面框沉頭鑽頭

That shaped profile really does the trick—the counterbore holes came out clean on my face frame joints, no chattering or tear-out. I’ve used it on about a dozen assemblies and it’s held its edge well so far.

The pilot tip grabs perfectly, so it stays centered without walking across the wood. My pocket hole plugs sit flush now, no sanding needed to level them out.

First time using a counterbore bit for face frames and the profile cut through the plywood with zero tear-out. It made drilling perfectly aligned holes for the screws a breeze, and the depth stop saved me from going too deep.
