Your drill bit slips in the chuck, walks off-center, or burns up the first time you hit rebar in concrete — and you wrote it off as a throwaway. This 9/32-inch titanium nitride drill bit is built to stay in the hole longer without walking or overheating. Titanium nitride coating resists heat buildup and bit walk, extending useful life in masonry and concrete. The 9/32-inch size covers the smaller end of hammer drill bits used for anchoring and electrical rough-in — the size you reach for most on a concrete fasten or pipe-run job. The 1/4-inch hex shank fits standard hammer drills without slipping under impact load. Standard on plumbing and electrical rough-in crews across northeast Nebraska and northwest Iowa — the bit that covers the most common pipe and conduit sizes without switching bi Stocked at Crofton Lumber and Akron Lumber.
