層板插銷鑽孔治具鑽頭（1/4"）

The hex shank snaps into my drill in seconds and doesn't wobble at all, which makes lining up the brad point tip feel precise. Drilled a dozen shelf holes in pine and every single one came out clean with zero tear-out on the backside.

The brad point tip really earns its keep—my holes came out clean and centered without any wandering on the first try. It’s small but hefty, and the hex shank stayed locked in my driver the whole time. Jig set-up took seconds, and I had all my shelf pins placed in under ten minutes.

The hex shank clicked right into my drill chuck with zero fuss, and the brad point tip bit into the wood cleanly without skating around. Drilled a row of shelf pin holes in about five minutes, all smooth and perfectly straight.
