Frequently Asked Questions

What is the CHICAGO-LATROBE Taper Length Drill Bit 55252 used for?

This TiN-coated HSS taper-length drill bit with a 135° split point and parabolic flute is designed for deep-hole drilling in metalworking. It efficiently clears chips in steel, stainless steel, and alloys, making it ideal for maintenance, fabrication, and production environments where precision and chip evacuation are critical.

What are the specifications of the CHICAGO-LATROBE 55252 drill bit?

The CHICAGO-LATROBE 55252 is a 5/16" (0.3125 inch) taper-length drill bit with a 135° split point, TiN-coated high-speed steel, and a parabolic flute design. It is part of the Chip-Clearing HSS Taper-Length Drill Bits series, optimized for deep-hole drilling and chip evacuation in ferrous materials.

Where to buy CHICAGO-LATROBE 55252 drill bits worldwide?

How to select the right taper-length drill bit for deep-hole drilling?

For deep-hole drilling, choose a bit with a parabolic flute design, like the CHICAGO-LATROBE 55252, to improve chip evacuation. A 135° split point reduces walking and thrust. Match the diameter (5/16") to your hole size and ensure the coating (TiN) suits the material—steel or stainless steel. Always use proper cutting fluid and pecking cycles.
