Drill a Perfectly Square Hole in One Plunge — No Chisel, No Cleanup, No Guesswork
Mortise-and-tenon joints used to mean a sharp chisel, a steady hand, and twenty minutes of paring corners by hand. EdgeCraft Pro™ drops that down to a single pull of the lever: a spinning auger clears the waste while a four-point square chisel shears the corners crisp, so you get a clean square recess in seconds instead of a half-hour of fiddling.
Stop Hand-Chiseling Mortises That Come Out Crooked and Loose
You mark it twice, chop it out by hand, and the tenon still rocks in the slot — so you pare a little more, and a little more, until the joint's sloppy. Round drill bits leave a round hole that won't hold a square tenon. Cheap mortise sets show up with rolled, soft edges that quit after a dozen holes. EdgeCraft Pro™ gives you a tight fit straight off the machine — square corners, flat walls, ready to glue.
➤ Square holes, square the first time: The auger and four-cornered chisel work as one — the drill hogs out the middle, the chisel walls shear the sides clean, so the slot comes out flat and tight without a follow-up hand chisel.
➤ Chip flutes that don't pack or burn: Deep spiral flutes lift sawdust up and out of the cut as you go, so the bit stays cool and doesn't clog mid-plunge — even in dense oak and maple.
➤ Stays super sharp longer: Heat-treated hardened steel holds its corners through repeated mortises instead of rolling over after the first project, so your joints stay crisp hole after hole.
How One Bit Does the Job of a Drill and a Chisel at Once
Look inside the square sleeve and there's a spinning auger bit. When you plunge, the auger drills out the bulk of the wood while the four sharpened corners of the outer chisel slice the round hole into a clean square. The chip flutes carry the waste up and away so nothing jams. One motion, one square hole — flat walls, sharp corners, no sanding.
A regular auger or Forstner bit can only ever leave you a round hole, which means rounding your tenons or chiseling four corners by hand on every single joint. EdgeCraft Pro™ puts the chisel and the drill on the same axis, so the square is built into the cut instead of fixed afterward.
Why Woodworkers Keep These on the Drill Press Instead of the Cheap Sets
Most square-hole sets get one bad review after another — soft chisels that roll, corners ground out of square, edges that need work before they'll even cut. EdgeCraft Pro™ users go in expecting the same and come out surprised. "Figured it'd be cheap junk like my last set that rolled after a dozen holes — I've punched 40 square mortises in white oak and the corners are still crisp." — Marcus T.
Joints So Tight the Tenon Practically Snaps Into Place
✓ Nice tight fit, no gaps: Flat square walls mean your tenon seats fully with no rocking and no daylight around the joint — the kind of fit that holds without relying on glue to fill the slop.
✓ Less fixing, more building: No paring corners by hand on every mortise, so a job that ate your whole afternoon now moves at the pace of pulling a lever.
✓ A genuine upgrade to your bench: Four common sizes cover most joinery, so this set earns its spot in the drawer instead of getting tried once and shelved.
Clean Square Mortises in 3 Simple Steps
Step 1: Mount the EdgeCraft Pro™ bit in your drill press mortising attachment or hollow chisel mortiser and set your depth stop.
Step 2: Line up the chisel over your marked layout line and pull the lever to plunge — the auger and chisel cut together.
Step 3: Step over by one chisel width and repeat to extend the mortise to any length you need. Clean, square, ready to glue.

Your Questions Answered — No Surprises, Just Confidence
Can I use these in a regular cordless or handheld drill?
No — and this is the one thing to check before you buy. Hollow chisel bits need the downward leverage of a drill press fitted with a mortising attachment, or a dedicated hollow chisel mortiser. They're not made to spin in a freehand drill.
Will they handle hardwood?
Yes. The chip flutes keep the cut clear so the bit doesn't pack or burn, and the hardened chisel holds its corners through oak, maple, and softwoods alike.
Do I need to sharpen them first?
They cut sharp out of the box. As with any chisel bit, a quick hone of the four inside corners before your first cut gives you the cleanest possible walls — a two-minute step seasoned woodworkers do by habit.
What sizes are included?
Four square sizes — 1/4", 5/16", 3/8", and 1/2" — which cover the large majority of furniture, cabinet, and frame joinery. Wider mortises are made by stepping the chisel across in overlapping cuts.
What if they don't perform?
If your mortises aren't coming out clean and square, return the set within 30 days for a full refund — no questions asked. Manufacturing defects are repaired or replaced.
