8 Tools for Digging and Setting Fence Posts
From post hole diggers to tamping bars, this guide covers the 8 essential tools you need to dig, set, and secure fence posts for a professional result.
There’s a certain satisfaction in looking down a perfectly straight line of fence posts, each one standing plumb and true. But getting there involves a lot of sweat and the simple, brutal physics of moving earth. Without the right tools, digging and setting posts turns from a challenging project into a downright miserable one.

Essential Prep Work for a Sturdy Fence Line
Before a single shovel of dirt is moved, a successful fence starts with a string line. Run a mason’s line tightly between two stakes to mark the exact path of your fence, ensuring it’s straight and positioned correctly on your property. This simple guide is non-negotiable; it prevents a wavy, amateur-looking fence line and saves you from having to re-dig holes.
Next, mark the precise location for each post along the string line with marking paint or a small flag. Standard spacing is typically eight feet, but adjust as needed for your terrain and fencing type. Most importantly, before you break ground, call 811 to have underground utilities marked. Hitting a buried power or water line is a dangerous and expensive mistake that is easily avoided with a free phone call.
Post Hole Digger – Seymour Structron Hercules
A post hole digger, often called a "clamshell" digger, is the foundational tool for this job. It’s designed for one thing: lifting soil straight up and out of a deep, narrow hole. This is your primary workhorse for digging in soil that is moderately cooperative—not pure sand, but not solid rock either.
The Seymour Structron Hercules stands out for its 48-inch fiberglass handles. Unlike wood, they won’t rot or splinter, and they absorb shock far better, saving your hands and shoulders over a long day. The riveted, high-carbon steel blades are tough enough to slice through small roots and hold their edge. This tool is built for leverage and durability, not finesse, which is exactly what you need.
Before buying, consider the hole diameter you need. A 6-inch digger is perfect for standard 4×4 wood posts, leaving enough room for concrete or gravel backfill. This tool is ideal for the homesteader putting in a garden fence or a small pasture line. It’s not the fastest option, but it’s reliable, requires no fuel, and will last a lifetime.
Manual Auger – Seymour Midwest Iwan Auger
Where a clamshell digger lifts, a manual auger drills. This tool is indispensable for soils that are loamy, sandy, or relatively free of large rocks. The screw-like design pulls soil upward as you turn the handle, creating a cleaner, more uniform hole with less effort than repeated plunging and lifting.
The Seymour Midwest Iwan Auger is a classic for a reason. Its welded steel construction is brutally simple and effective, with a traditional hardwood handle that provides a solid grip. The key is the Iwan pattern head, which features two blades that excel at boring into the ground without getting easily clogged. It’s a surprisingly efficient way to move earth.
A manual auger shines when you need precise, clean holes and your soil allows for it. It’s less jarring on the body than a clamshell digger, making it a good choice for those with back or shoulder issues. However, it will stop dead on a large rock or thick root, requiring you to switch to a digging bar. For projects in predictable, soft soil, this auger can significantly speed up your work.
Gas-Powered Auger – Earthquake Powerhead Earth Auger
This Earthquake powerhead delivers reliable digging power with its 43cc Viper engine and durable, steel-welded construction. It features anti-vibration handles for comfortable use and a rugged auger bit with replaceable blades for lasting performance.
When you have more than 15 or 20 holes to dig, or your ground is a nightmare of clay and rock, a gas-powered auger is no longer a luxury—it’s a necessity. This machine replaces raw muscle with horsepower, drilling a perfect hole in a fraction of the time it would take manually. It saves your back and turns a multi-day project into a single-afternoon task.
The Earthquake Powerhead Earth Auger is a solid choice for the small-farm scale. Its Viper engine is reliable and provides enough torque to chew through compacted soil and power through smaller roots. The unit is designed to be operated by one person, with durable, foam-padded handlebars that help absorb the intense vibration. Bits are sold separately, so you can choose the right diameter (8-inch is a versatile starting point) for your specific posts.
Be warned: a gas auger is a powerful and potentially dangerous tool. It can kick back violently if it hits a large, immovable object, so a firm grip and proper stance are critical. It’s also heavy and loud. This tool is for the serious homesteader with a lot of fence to run, not for someone setting four posts for a mailbox.
Digging Bar – Bully Tools San Angelo Digging Bar
This heavy-duty steel bar is ideal for tamping and digging with its durable, all-steel construction. Made in the USA, it features a solid steel bar and thick plate for reliable performance.
No matter how good your soil seems, you will eventually hit something your digger can’t handle: a buried rock, a thick tree root, or a layer of hardpan clay. This is where the digging bar comes in. It is your problem-solver, a simple lever of solid steel designed to break, pry, and dislodge whatever is in your way.
The Bully Tools San Angelo Digging Bar is the one to get. It’s made from 100% American-made, high-strength steel and features two distinct ends. One end is a sharp, pencil-like point for shattering rock and hardpan; the other is a flat, chisel-like tamper for cutting roots or compacting soil. At 17 pounds, it has the heft to do serious work without being completely exhausting to lift.
This is not an optional tool. Attempting to dig a fence line without a solid digging bar on hand is a recipe for frustration. You’ll use it to break up compacted soil at the bottom of the hole, pry out stubborn rocks, and slice through roots that would stop an auger cold. It is pure, simple, and absolutely essential.
Tamping Bar – Nupla Classic Tamping and Digging Bar
Digging the hole is only half the battle; setting the post securely is what makes a fence last. A tamping bar is specifically designed to compact the soil or gravel you add back into the hole around the post. Proper tamping eliminates air pockets, locking the post in place and preventing it from leaning over time.
The Nupla Classic Tamping and Digging Bar combines two functions. One end is a heavy, 8-inch by 8-inch steel tamper head for compacting backfill. The other end is a digging chisel, useful for light-duty clearing. The key feature is its Nuplaglas fiberglass handle, which dramatically reduces vibration and is resistant to weather and rot.
Many people try to skip this step or use a piece of scrap wood, but the results are never the same. A dedicated tamping bar allows you to apply focused force in the narrow space between the post and the hole wall. By adding backfill in 4-to-6-inch layers and tamping each one thoroughly, you create a foundation that is as solid as concrete.
Post Driver – SpeeCo T-Post Driver with Handles
While this article focuses on digging holes for wood or metal posts, many farm fences rely on simple metal T-posts. You don’t dig holes for these; you drive them directly into the ground. A post driver is a weighted, hollow steel tube with handles that makes this possible without destroying the top of the post or your hands.
The SpeeCo T-Post Driver is the standard for this task. It’s a heavy-walled cylinder with two large, welded handles that provide a secure grip. You simply slide the driver over the top of the T-post, lift it, and use its own weight to drive the post into the earth. The heavy steel does most of the work, saving you from swinging a sledgehammer.
This tool is for one job only: driving T-posts, rebar, or grounding rods. It is completely unsuited for wooden posts. If your fencing plan involves a mix of sturdy wooden corner posts and intermediate metal T-posts, this driver is a must-have. It makes installing T-posts fast, safe, and efficient.
Post Level – Swanson Tool Co. PostRite Folding Level
A fence post that isn’t plumb (perfectly vertical) will stick out like a sore thumb and compromise the strength of the entire fence line. A post level is a specialized tool that straps directly to the post, allowing you to check for plumb in two directions at once. It eliminates the guesswork of holding a standard level against the post while trying to brace it.
The Swanson Tool Co. PostRite Folding Level is a smart, simple design. It has three vials to check plumb on two perpendicular sides simultaneously, plus a level vial for horizontal applications. Its durable, high-impact body can take job site abuse, and the included rubber strap holds it securely to posts of any size or material—square, round, wood, or metal.
You can try to get by with a standard torpedo level, but it’s clumsy. The hands-free operation of a dedicated post level allows you to make minor adjustments to the post’s position while keeping an eye on the bubbles. For the small cost, this tool adds a layer of precision that separates a professional-looking fence from a sloppy one.
Transfer Shovel – Fiskars Pro D-Handle Transfer Shovel
Once the post is in the hole, you need to backfill it with the soil you removed or, ideally, with gravel and concrete. A transfer shovel, with its flat-bottomed, deep-sided blade, is built for moving loose material like this. It’s far more efficient than a pointed digging shovel for scooping gravel from a pile or mixing concrete in a wheelbarrow.
The Fiskars Pro D-Handle Transfer Shovel is a modern, ergonomic take on a classic tool. It features a heavy-gauge steel blade that won’t bend under a heavy load of wet concrete or gravel. The real advantage is the extruded aluminum handle with a D-handle design, which is lighter than wood but incredibly strong, reducing fatigue over a long day of mixing and backfilling.
Don’t underestimate the need for a good shovel. You’ll use it to place a gravel base at the bottom of the hole for drainage, to scoop concrete mix, and to carefully place backfill soil for tamping. Its wide, flat blade is also perfect for cleaning up the work area when you’re done.
Manual vs. Powered Diggers: Making the Choice
Choosing between a manual post hole digger and a powered auger comes down to three factors: soil condition, scale, and physical ability. There is no single "best" answer, only the right tool for your specific situation.
Manual diggers—both clamshell and auger types—are perfect for small projects of up to 15-20 holes in soil that is relatively free of rocks and hard clay. They are inexpensive, require no maintenance or fuel, and give you a great workout. If your land is workable and your fencing needs are modest, a manual digger is the most practical and economical choice.
A gas-powered auger becomes the right choice when facing tough soil conditions or a large number of holes. If you have more than 20 posts to set, or if you know your ground is compacted, root-filled, or rocky, the investment in a powered auger will pay for itself in saved time and physical exhaustion. For those on the fence, consider renting one for a day; it’s a great way to tackle a big job without the cost of ownership.
Tips for Setting Posts Plumb, Level, and Secure
A well-dug hole is just the start. To ensure your posts last for decades, start by adding 4 to 6 inches of coarse gravel to the bottom of the hole before setting the post. This creates a French drain that allows water to escape, dramatically slowing rot at the post’s base—the most common point of failure.
Once the post is in place and plumbed with your level, backfill in layers. Whether you’re using soil, gravel, or concrete, add only about 6 inches of material at a time. After each addition, use your tamping bar to aggressively compact the material all the way around the post. This process is tedious but critical; it removes air pockets and locks the post into the ground so it won’t shift under pressure or frost heave.
For corner posts and gate posts that will be under constant tension, using concrete is highly recommended. Mix it to a thick, peanut-butter-like consistency—too wet, and it loses strength. Slope the top of the concrete footing away from the post so that it sheds water, further protecting the wood from moisture.
Safety First: Proper Fencing Posture and Gear
Fencing is hard physical labor that puts a strain on your back, hands, and joints. Always wear the right personal protective equipment (PPE). This includes sturdy leather gloves to prevent blisters and splinters, safety glasses to protect from flying dirt or rock chips, and steel-toed boots to guard against a dropped tamping bar or post.
When using manual diggers, focus on proper body mechanics. Lift with your legs, not your back. Keep your spine straight and your core engaged. When using a powered auger, maintain a wide, stable stance and be prepared for the machine to kick back. Never wear loose clothing that could get caught in the rotating auger.
Finally, know your limits. Fencing is a marathon, not a sprint. Stay hydrated, take regular breaks, and don’t try to dig 50 holes in a single day if you’re not conditioned for it. Working smart and safe ensures you can finish the project without injury.
Building a good fence is a fundamental skill on any farmstead, and having the right set of tools transforms it from an ordeal into a deeply rewarding project. Invest in quality tools, take your time with the prep work, and you’ll build a fence that stands strong for years to come.
