Chicago-latrobe 44276 No. 6 Hss Jobber Drill Bit

Product Description

The CHICAGO-LATROBE 44276 is a jobber length twist drill bit manufactured from high speed steel with a bright uncoated finish. Sized to wire gauge No. 6, the cutting diameter measures 0.2040 inches. The 118-degree standard point angle suits general-purpose drilling across a broad range of workpiece materials. Overall length is 3.75 inches, with a 2.5-inch spiral flute and a straight-cylindrical shank diameter of 0.2040 inches. The web-thinned, tapered-web geometry reduces thrust at entry and improves chip evacuation. This is a hand-tool and machine-shop consumable installed by machinists, maintenance technicians, plumbers, and electricians in production and field settings alike.

The 44276 is suited to drilling non-ferrous metals including aluminum, copper, brass, and similar alloys, as well as general-purpose applications in plastics and softer materials. The right-hand cut, regular spiral flute pattern promotes efficient chip removal during through-hole and blind-hole operations. With a Series 150D designation and DIN 338 compliance, this bit fits standard jobber-length drill chucks on benchtop drill presses, cordless and corded hand drills, and CNC drilling fixtures that accept straight-shank tooling.

Key Features

• Wire gauge No. 6 cutting diameter: 0.2040 inches, held to a tolerance of -0.0007 to 0.0000 inches
• High speed steel construction for durability across general-purpose drilling tasks
• 118-degree standard point angle with web-thinned, tapered-web geometry for reduced entry thrust
• Bright uncoated finish compatible with standard cutting fluids and lubricants
• Regular right-hand spiral flute, 2.5-inch flute length, promotes consistent chip evacuation
• DIN 338 compliant; straight-cylindrical shank fits standard drill chucks without adapters

Compatibility

Designed for use in standard drill chucks accepting a 0.2040-inch straight-cylindrical shank; compatible with drill presses, hand drills, and CNC spindles conforming to DIN 338 jobber-length tooling specifications. Primary workpiece material rating is non-ferrous metal.

Installation Notes

Secure the shank fully in the drill chuck and verify chuck key is removed before starting the spindle. Apply an appropriate cutting fluid or lubricant when drilling non-ferrous metals to extend bit life and improve hole finish. Reduce feed pressure near breakthrough to prevent grab or workpiece deformation. Inspect the cutting edges for wear before each use; a dull bit increases thrust load and can damage the workpiece or shank.
