Chicago-latrobe 44349 Jobber Drill Bit 0.0145 in Wire 79

Product Description

The CHICAGO-LATROBE 44349 is a jobber-length drill bit designed for precision drilling in non-ferrous metals and other general-purpose materials. It measures 0.0145 inches in diameter, corresponding to wire gauge size 79, with an overall length of 0.75 inches and a flute length of 0.125 inches. The bit is manufactured from high speed steel with a bright, uncoated finish and features a standard 118-degree split point with web thinning for improved penetration and reduced walking on entry. This is a bench or hand-drill bit suited for machinists, maintenance technicians, and trade professionals requiring small-diameter precision drilling.

The 44349 is built for general-purpose drilling applications in non-ferrous metals such as aluminum, brass, and copper, as well as plastics and light materials. Its right-hand spiral flute design efficiently evacuates chips during through-hole and blind-hole drilling. The straight-cylindrical shank fits standard drill chucks without adapters, making it straightforward to deploy in drill presses, CNC machines, or hand drills wherever a wire-gauge 79 hole is required.

Key Features

• Wire size 79 diameter: 0.0145 inches for small-diameter precision work
• High speed steel construction for durability across general-purpose drilling tasks
• 118-degree standard point angle with web thinning for cleaner entry and reduced thrust
• Bright, uncoated finish compatible with cutting fluids or dry drilling
• Regular spiral, two-flute design for efficient chip evacuation
• Straight-cylindrical shank fits standard drill chucks without adapters

Compatibility

Designed as a general-purpose jobber-length drill bit conforming to DIN 338 standards, compatible with any standard drill chuck accepting a straight-cylindrical shank in the wire-gauge size range.

Installation Notes

Installation of small-diameter drill bits should be performed by a qualified machinist or tradesperson familiar with proper chuck seating and runout checks. Secure the straight-cylindrical shank fully in the chuck before use to minimize deflection and bit breakage at this diameter. For non-ferrous metals, use a compatible cutting fluid to extend tool life and maintain hole quality. Inspect the bit for tip damage before each use, as small-diameter high speed steel bits are susceptible to breakage under lateral loading.
