Frequently Asked Questions

What is a CHICAGO-LATROBE taper length drill bit used for?

This CHICAGO-LATROBE taper length drill bit is designed for deep-hole drilling in metal, wood, and plastics. Its parabolic flute clears chips efficiently, while the 135° split point reduces walking and thrust. It is ideal for maintenance, fabrication, and production environments requiring precise, repeatable holes.

What are the specifications of the CHICAGO-LATROBE 55249 drill bit?

The CHICAGO-LATROBE 55249 is a 17/64" taper length drill bit with a 135° split point. It features TiN-coated high-speed steel and a parabolic flute design for chip clearing. The bit diameter is 0.2656 inches. It is suitable for general-purpose drilling in ferrous and non-ferrous materials.

How to select the right taper length drill bit for deep holes?

For deep-hole drilling, choose a taper length bit with a parabolic flute, like this CHICAGO-LATROBE 55249, to clear chips effectively. The 135° split point helps start holes without a center punch. Match the bit diameter (17/64") to your hole size and ensure the shank fits your drill chuck. Use cutting fluid for steel.
