Make it Snappy Tools 直柄鑽頭沉頭鑽

Drilled about twenty pilot holes in oak this afternoon, and the straight shank held firm without any wobble. The countersink depth was perfectly consistent each time, which saved me from having to switch bits.

The pilot hole and countersink in one pass saved me so much time on my deck project. Straight shank drills cut clean and the countersink leaves a flush finish every time.

Was tired of drilling two separate holes for every pilot and countersink, so this combo bit saved me a ton of time on my last cabinet build. The pilot and countersink cut clean in one pass, and the straight shank lines up perfectly with my modern screws.
