Chicago-Latrobe 49717 Taper Length Drill Bit
The Chicago-Latrobe 49717 is a taper length drill bit made from high speed steel with a black oxide finish. It features a 17/64 inch diameter and a 118 degree radial point angle. This accessory is built for general purpose drilling in a variety of materials.
Suited for general workshop drilling tasks
This bit suits machinists and maintenance crews needing extra reach for deep holes in steel or cast iron. It is not for buyers who require a split point for self-centring without a centre punch. Users needing cobalt alloy for high temperature alloys or carbide for abrasive materials should look at something else.

Questions about this item
How do I install the 17/64 in HSS drill bit in my drill chuck, and what step do people often get wrong?
Open the chuck wide, insert the shank fully, then tighten securely. The common error is not seating the shank all the way, which causes run-out and premature wear on the 118-degree point.
What maintenance or replacement will the 49717 taper-length bit need over time?
The black oxide coating reduces friction but wears off. Resharpen the 118-degree radial point when cutting slows, and replace the bit once the high-speed steel flutes are too short to clear chips effectively.
