Frequently Asked Questions

What is the CHICAGO-LATROBE Taper Length Drill Bit 55250 used for?

This drill bit is designed for deep-hole drilling in metalworking applications. Its parabolic flute design efficiently clears chips, while the 135° split point reduces walking and eliminates the need for a center punch. It is commonly used in industrial manufacturing and maintenance for drilling precise holes in steel, stainless steel, and other alloys.

What are the specifications of the CHICAGO-LATROBE 55250 drill bit?

The CHICAGO-LATROBE 55250 is a taper-length drill bit with a 9/32" (0.2813 inch) diameter. It features a 135° split point, TiN-coated high-speed steel (HSS) construction, and a parabolic flute design. The TiN coating reduces friction and extends tool life. This bit is designed for chip-clearing efficiency in deep-hole drilling.

Where to buy CHICAGO-LATROBE 55250 drill bits worldwide?

3G Electric supplies the CHICAGO-LATROBE 55250 taper-length drill bit to customers worldwide. As a global industrial equipment distributor, 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?

Select a taper-length drill bit with a parabolic flute for efficient chip evacuation in deep holes. The 135° split point helps prevent walking on curved surfaces. For harder materials, choose a TiN-coated HSS bit like the CHICAGO-LATROBE 55250 to reduce friction and heat. Match the diameter (9/32") to your hole size requirement.
