What is the CHICAGO-LATROBE Taper Length Drill Bit 55254 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, reducing friction and heat. Common in automotive, aerospace, and general fabrication where precise, clean holes are required.

What are the specifications of the CHICAGO-LATROBE 55254 drill bit?

The CHICAGO-LATROBE 55254 is a taper-length drill bit with a 11/32" (0.3438 inch) diameter. It features a 135° split point, TiN-coated high-speed steel (HSS) construction, and a parabolic flute design for efficient chip evacuation. The manufacturer part number is 55254.

Where to buy CHICAGO-LATROBE 55254 drill bits worldwide?

3G Electric supplies the CHICAGO-LATROBE 55254 taper-length drill bit to customers worldwide. As a global industrial equipment distributor since 1990, we handle full logistics, customs clearance, and delivery to your location. Contact us for availability and lead time.

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

For deep-hole drilling, choose a taper-length bit with a parabolic flute, like the CHICAGO-LATROBE 55254, to improve chip evacuation. A 135° split point reduces walking and thrust. Ensure the diameter matches your hole size (11/32") and the coating (TiN) suits the material hardness. Always use proper cutting fluid.
