Chicago-Latrobe 55115 Screw Machine Drill Bit

This Chicago-Latrobe 55115 is a screw machine drill bit built for production drilling tasks. It is made from high speed steel with a TiN coating for extended wear life. The bit suits machinists and maintenance crews who need consistent hole quality in metal.

23/64 inch size with 118 degree point angle

The decisive specification is the 23/64 inch diameter paired with a 118 degree conventional point angle. This combination determines whether the bit matches the hole size and material you are drilling. The decimal equivalent is .3594 inch for precise setup.

Suited for right-hand cutting in ferrous

Buyers who need a non-coolant-through bit for screw machine or portable drilling will find this fit for purpose. It is not for left-hand cutting applications or for jobs requiring through-coolant delivery. Buyers who want a different diameter or point geometry should look at other options.

Questions about this item

How deep can the 23/64 inch drill bit reach in a screw machine setup?

The 23/64 inch size with 118 degree point angle is designed for screw machine drilling where shorter flute lengths provide rigidity for accurate holes in metal stock.

What does the 118 degree point angle mean for drilling performance?

The 118 degree conventional point angle on this high speed steel bit offers general-purpose cutting across steel and other ferrous materials with reliable centering.

Will the TiN coated 55115 bit fit my standard drill chuck?

The right-hand cutting drill bit uses a straight shank sized to the 23/64 inch diameter, fitting standard three-jaw chucks that accommodate that capacity.
