Chicago-latrobe 44112 Jobber Drill Bit Size 42 Hss

Product Description

The CHICAGO-LATROBE 44112 is a jobber-length drill bit designed for general-purpose drilling in ferrous materials. It carries a wire gauge size of 42, equal to 0.0935 inches in decimal. The bit is manufactured from high speed steel with an oxide finish that provides basic lubricity and corrosion resistance during cutting. The two-flute spiral design clears chips efficiently, and the 118-degree standard point angle suits flat entry into cast iron and steel stock. Overall length is 2.25 inches with a flute length of 1.25 inches. The straight-cylindrical shank measures 0.0935 inches in diameter and fits standard keyless or keyed drill chucks. This is a Series 150 general-purpose tool used by machinists, maintenance technicians, and fabricators.

The 44112 is suited for drilling cast iron and steel in light-production and maintenance settings. Its jobber length makes it a practical everyday bit for bench drill presses, hand drills, and CNC applications where a compact flute length and standard reach are sufficient. The web-thinned, tapered-web design reduces thrust requirements at entry, which is useful when drilling smaller-diameter holes in harder ferrous stock. It conforms to DIN 338 dimensional standards, making it compatible with metric-chuck tooling setups as well as imperial equipment.

Compatibility

Designed as a general-purpose jobber-length drill bit for use in cast iron and steel applications. Suitable for standard keyless and keyed drill chucks accepting a 0.0935-inch straight-cylindrical shank.

Installation Notes

Installation and use of this bit should be performed by machinists or qualified trade professionals familiar with rotary cutting tools. Secure the shank fully in the chuck before operation and verify chuck key removal prior to starting the drill. Use appropriate cutting fluid or coolant when drilling steel to extend tool life and maintain hole tolerance. Always wear appropriate eye protection and follow applicable shop safety standards when operating drilling equipment.
