Reversible Drill Bits for Sheet Metal
When one end becomes worn, reverse the bit to use the other end. These bits have short flutes and a sturdy construction which prevent snagging that deforms sheet metal and thin-wall tubing. They can be used in both hand-held drilling and machine-tool applications. The split point keeps the bit centered without a pilot hole.
