Extra Long 17/64" HSS Drill Bit

This extra-long drill bit from Chicago-Latrobe is built from high-speed steel with a black oxide finish for machining performance. The 135-degree split point design helps reduce walking and starts holes cleanly in metal. It suits professional mechanics and fabricators who need extended reach for deep-hole drilling tasks.

Check Shank Fit and Application Needs

Verify that your drill chuck accepts a 17/64-inch fractional shank before ordering. The bit achieves a maximum drilling depth of 2 7/8 inches and is designed for 4xD applications, so confirm this length matches your workpiece thickness. Buyers needing a shorter flute length or a different point angle for softer materials should select another tool.
