The Problem Every Woodworker Knows (But Often Endures Silently)

You're working on something you're proud of—a bookshelf for your daughter, a jewelry box for your partner, or maybe a cabinet you've been planning for weeks. You measure, cut, and everything fits... until it’s time to cut those square holes. Suddenly, your momentum hits a wall.
You try chiseling by hand—slow, uneven, and exhausting. Maybe you attempt to "square" a round drill hole, only to end up widening it too much or splintering the wood. You curse under your breath, waste another piece, and reach for coffee that’s already gone cold.
If you're like most craftspeople, you've probably thought, "There has to be a better way

Meet the Adapter That Works as Hard as You Do

The Square Hole Drill Bits Adapter Bracket is the better way.
This bracket doesn’t just hold your bit—it gives your entire process stability, control, and finesse. Mount it onto your drill press column, insert a square-hole chisel bit, and instantly convert your setup into a capable mortising machine. It keeps your drill bit and chisel aligned perfectly, so every punch-through is clean, controlled, and centered—no more fumbling, readjusting, or ruining good wood.
Instead of struggling through one mortise for 15 minutes, you’ll glide through dozens in a single session—with accuracy you can see and feel.

Built for Real Work, Not Shelf Appeal

The design isn’t flashy—and that’s a good thing. It’s built like a tool should be: sturdy, no-nonsense, and made to last. The high-strength alloy body resists bending, slipping, or loosening over time, no matter how many mortises you cut. With precise bolt clamping and firm column support, it stays rock-solid during even the most aggressive drilling.
Each component, from the adjustable jaws to the finely machined screw knobs, is engineered to give you confidence that every hole will be exactly where—and how—you want it.
Whether you're a full-time woodworker or a passionate weekend builder, this adapter blends seamlessly into your workshop and steps up your results.

It’s Not Just About Clean Holes—It’s About Creative Freedom

When your tools work with you—not against you—you feel unstoppable.
There’s something deeply rewarding about a perfectly cut mortise that fits flush, tight, and right on the first try. This bracket doesn’t just make the process easier—it restores the creative momentum that frustrating tasks can steal.
Suddenly, you're not dreading joinery work—you’re looking forward to it. You plan more confidently. You finish faster. And at the end of the day, you're not just producing projects—you’re crafting pieces you're proud of.
Because woodworking isn't just about what you build. It's about how you feel while you're building it.

You’ve already invested time, money, and heart into your craft—don’t let poor tools limit your results. This adapter is not some novelty gadget—it’s a serious upgrade that brings consistency, speed, and joy back into your projects.

I used to hate cutting mortises—always took forever and never looked clean. This bracket paired with my drill press makes the process smooth and accurate. Worth every penny

Mark G., New Jersey

I build custom cabinets and this saved me hours on joinery. Super sturdy, easy to set up, and honestly more accurate than my old benchtop mortiser

Rachel T., Oregon

I thought it would be okay for small jobs, but I’ve run dozens of mortises through it and it hasn’t slipped once. Holds alignment really well
