鑽頭套組，29件，螺絲機長度 HSS

I was tired of digging through mismatched bits mid-project, so having every 64th from 1/16" to 1/2" in one indexed case is a real time-saver. The shorter screw machine length makes them stiffer than my old jobber set, which means less wandering on the pilot hole.

These bits cut through steel like butter, and having every 64th from 1/16 to 1/2 inch means I always have the exact size I need.

I’ve been using these screw machine length drills for a few weeks now and they fit perfectly in tight spots where my old jobber bits wouldn’t reach. The 64ths sizing gives me just the right increments between 1/16 and 1/2 inch. Pretty happy with the purchase.
