Get Flawlessly Square Mortise Holes Without Wasting Hours on Cleanup
Imagine sliding perfect tenons into mortises so precise they lock in place instantly — no awkward gaps, no shim tricks, no endless chisel cleanup. The TrueEdge™ Mortise Drill Set carves sharp, square holes in a single plunge, saving you time and leaving every joint rock-solid and beautifully flush. Finally, your DIY projects finish on schedule — not swallowed by frustration.

Stop Letting Round Holes Ruin Your Weekend
Tired of drilling round holes and then wasting precious time chasing square corners with a chisel? That frustrating rocking tenon and visible glue lines aren’t just ugly—they’re a constant reminder that your tools are holding you back. With TrueEdge™, every hole comes out perfectly squared on the first try, so you can ditch the tedious hand-chiseling and actually enjoy your workshop time.
➤ Flawless square cuts instantly: The tough hollow chisel carves the four sharp walls while the inner auger clears chips seamlessly — one smooth plunge creates the perfect mortise, no extra effort needed.
➤ Engineered for real wood precision: Precision-ground for pine, MDF, hardwoods, and more, the cutting edges slice cleanly through wood fibers without dulling or tearing.
➤ Ready to work out of the box: Every piece arrives razor-sharp so you can hit the ground running — no dull edges, no frustrating prep, just effortless cuts from the first hole.

Meet TrueEdge™ — The Mortise Bit That Combines Two Tools Into One Dead-Square Cutting Machine
TrueEdge™ isn’t just a bit — it’s a revolution inside your workshop. The outer hollow chisel sharpens every corner to flawless square perfection while the inner auger spins away chips, leaving behind only crisp, clean mortises that fit like a glove. No wobble, no mistakes, every hole identical from start to finish.
The milled round shaft fits snugly into your mortising machine or drill press attachment for rock-solid stability, eliminating vibration and giving you surgical precision straight from the first cut.

What Passionate Woodworkers Are Saying After Their First Use
“I expected to spend time sharpening like with my old bits — but these were razor-sharp right out of the box. I cut twenty perfect mortises on a Sunday morning, and every tenon fit flush without a hitch.” — Keith B.

How TrueEdge™ Changes Your Joinery Game for Good
✓ One plunge, perfect square: Every mortise comes out clean and true — forget sanding, chiseling, or adjusting for fit.
✓ Rock-solid joints without gaps: Your tenons sit flush and tight with no wiggle, boosting strength and pure workshop pride.
✓ Long-lasting sharpness: Built tough, TrueEdge™ stays sharp through your heaviest builds, keeping your workflow smooth and your precision sharp.
Set Up Once, Drill Like a Pro Every Time
Step 1: Handle carefully — the edges are sharp enough to thrill professional woodworkers from the get-go.
Step 2: Insert the bit securely into your mortising machine’s bushing and spindle — stability is key to flawless, chatter-free cuts.
Step 3: Add a thin shim (think credit card thickness) between the auger tip and chisel face — this gap stops binding and lets chips escape easily, keeping every cut smooth and worry-free.

Your Most Pressing Questions, Answered Honestly
Can I use these with my regular drill or bare drill press?
These bits demand a mortising machine or a drill press fitted with a mortising attachment to hold the chisel perfectly square. They won’t fit or function properly in a handheld drill or standard drill press — trying will just waste your money and time.
Are they sharp enough straight out of the box?
Absolutely. These arrive with razor-sharp edges ground to perfection so you can start working immediately — no frustrating sharpening or prep required.
Which woods will TrueEdge™ handle cleanly?
Perfect on pine, MDF, particleboard, linden, and hardwoods like oak or maple. Avoid metal, glass, plastic, or concrete — those will dull or chip the edges.
How do I prevent the bit from binding mid-cut?
Maintain a tiny 0.02–0.04" gap (about a credit card’s thickness) between the auger tip and the chisel sleeve. This gives chips a clear escape path and stops the bit from catching on the edges.
Is expert skill needed to get perfect holes?
Not at all. Clamp your workpiece, set your depth, pull the lever. The geometry does the heavy lifting. After a couple test cuts, your mortises will be indistinguishable from pro shop perfection.

Make Flawless Mortises Your New Workshop Standard
TrueEdge™ won’t magically transform your skills overnight — but it will erase the tedious, frustrating cleanup that steals all the joy from joinery. Set it once, drill every hole flawlessly, and experience the confidence of joints cut the way the pros have for generations.
