Chicago-latrobe 44308 Wire 38 Jobber Drill Bit Hss 118 Deg

Product Description

The CHICAGO-LATROBE 44308 is a jobber length drill bit in wire gauge size 38, equivalent to 0.1015 inches in decimal diameter. Built from high-speed steel with a bright uncoated finish, it features a standard 118-degree split point and a web-thinned, tapered web for reduced thrust on entry. The two-flute spiral design with regular helix promotes efficient chip evacuation. With an overall length of 2.5 inches and a flute length of 1.4375 inches, this bit is sized for precision drilling in light-duty production and maintenance applications. HVAC technicians, plumbers, electricians, and general trade professionals use this bit for clean hole-making in non-ferrous metals and similar materials.

The 44308 is suited for general-purpose drilling in non-ferrous metals such as aluminum, brass, and copper, as well as plastics and similar soft materials. Its straight cylindrical shank seats securely in standard drill chucks on hand drills, drill presses, and CNC machines. The 118-degree point angle makes it a versatile choice across a broad range of light-to-medium drilling tasks encountered in field service and shop environments. Conformance to DIN 338 ensures consistent dimensional standards across the series.

Installation Notes

This bit is installed and serviced by any trade professional or machinist using a standard keyed or keyless drill chuck. Ensure the shank is fully seated and the chuck is tightened securely before operation. Run at appropriate spindle speeds for the workpiece material to avoid overheating the uncoated HSS cutting edge. Inspect the cutting edges before each use and replace if chipping or dulling is observed.
