CHICAGO-LATROBE Taper Length Drill Bit: 25/64", 135° Split Point, TiN-Coated HSS

A CHICAGO-LATROBE taper length drill bit is used for deep-hole drilling in metalworking and industrial machining. Its parabolic flute design clears chips efficiently, while the 135° split point reduces walking and thrust. It suits applications across automotive, aerospace, and general fabrication where precision and chip evacuation are critical.

The CHICAGO-LATROBE 55257 is a 25/64" taper length drill bit with a 135° split point, TiN-coated HSS, and parabolic flute. The drill diameter is 0.3906 inches. It is designed for chip-clearing in deep-hole drilling and is part of the Chip-Clearing High-Speed Steel Taper-Length Drill Bits category.

Select a taper length drill bit based on hole depth, material, and chip evacuation needs. For deep holes, choose a parabolic flute design like the CHICAGO-LATROBE 55257 to clear chips. Match the drill diameter (e.g., 25/64") to your hole size and consider coatings like TiN for extended tool life in ferrous metals.
