Chicago-latrobe 44334 Jobber Drill Bit 0.036 in Wire 64 Hss

Product Description

The CHICAGO-LATROBE 44334 is a jobber-length twist drill bit designed for general-purpose drilling in non-ferrous metals and similar materials. Built from high-speed steel (HSS) with a bright, uncoated finish, it measures 0.036 inches in diameter — wire gauge size 64 — with a 118-degree standard point angle. The overall length is 1.5 inches, and the flute length is 0.625 inches. The straight cylindrical shank seats cleanly in standard drill chucks. This bit suits machinists, maintenance techs, and trade professionals who need a reliable small-diameter drill for light metalworking, pilot holes, or precision applications.

The 44334 is suited for drilling non-ferrous metals including aluminum, brass, copper, and similar softer alloys. Its compact jobber-length profile makes it practical for benchtop drill presses, handheld drills, and CNC drilling operations where a short, rigid bit is preferred. The two-flute spiral configuration provides efficient chip evacuation in through-hole and blind-hole applications. This bit follows DIN 338 standards, making it a recognized specification in industrial and MRO environments.

Key Features

• 0.036-inch diameter, wire gauge size 64, with a tolerance of -0.0005 to 0.0000 inches for close-tolerance hole sizing
• 118-degree standard point angle with web-thinned, tapered web geometry for easier penetration in small-diameter applications
• High-speed steel construction with bright, uncoated finish for use in non-ferrous metals and general-purpose materials
• Right-hand cut, regular spiral, two-flute design promotes consistent chip removal
• Straight cylindrical shank compatible with standard drill chucks and collets
• Conforms to DIN 338 dimensional standards for consistent interchangeability

Compatibility

Designed as a general-purpose jobber-length drill bit per DIN 338 specifications, compatible with standard three-jaw drill chucks and collets accepting straight cylindrical shanks. Intended for use in non-ferrous metal workpieces as noted in the Series 150D product line.

Installation Notes

Install into a properly sized chuck or collet and tighten securely before operation. Secure the workpiece with a vise or fixture before drilling — never hand-hold small parts. For small-diameter bits like this, use appropriate drilling speeds per established feeds-and-speeds references for the workpiece material to avoid bit deflection or breakage. Inspect the cutting edges before each use; small-diameter HSS bits are susceptible to tip damage if dropped or improperly stored.
