Make it Snappy Tools 3件式 HSS 錐形沉頭鑽頭組

The three sizes in this set cover pretty much every tapered wood screw I keep in the shop, and the HSS tips still bite cleanly after a few dozen holes. Countersinks sit flush in one step, no wobble, no chipping around the rim.

The tapered bits cut clean pilot holes and countersinks in one pass, which saved me a ton of time on my last batch of pine shelves. Three sizes cover everything from #6 to #10 screws, and they still feel sharp after a few dozen holes.

Used these on a pine shelf project with tapered screws and the countersinks sat flush every time. The 5/64 pilot hole is a touch small for harder woods like oak, so I had to drill a starter hole first. Still, three sizes in the set covers most of what I need.
