Import BDNA-KP65114 Jobber Drill Bit Letter M Hss

Product Description

The IMPORT BDNA-KP65114 is a jobber-length twist drill bit sized to Letter M, equivalent to 0.2950 inches in decimal. Constructed from high speed steel with an oxide coating, this bit handles general-purpose drilling in metal, wood, and plastics. The standard 118-degree point angle suits a wide range of common materials without requiring specialized grinding. Web thinning at the tip reduces thrust and improves penetration, making it practical for hand-held drills and drill presses alike. With a 4-3/8-inch overall length and straight-cylindrical shank, it seats directly in standard three-jaw chucks. Machinists, pipefitters, ironworkers, and maintenance technicians keep this size in regular rotation.

This bit is suited for general-purpose hole-making applications in trade and light industrial settings. Typical uses include drilling clearance holes for fasteners, creating pilot holes ahead of taps, and boring holes in structural steel, pipe, sheet metal, and similar materials. The 3-1/16-inch flute length provides adequate chip evacuation in moderate-depth holes. It is sold individually and is appropriate for both bench drill press work and portable drill use in residential and commercial maintenance applications.

Key Features

• Letter M size: 0.2950 inches decimal equivalent for precise hole sizing
• 118-degree standard point angle for general-purpose drilling across common materials
• High speed steel construction with oxide coating for corrosion resistance and heat dissipation
• Web-thinned tip reduces cutting thrust and improves bit entry
• Tapered web and regular spiral flute geometry promote consistent chip clearing
• Straight-cylindrical shank fits standard three-jaw drill chucks without adapters

Compatibility

Designed as a general-purpose jobber-length drill bit compatible with any standard three-jaw chuck accepting a 0.2950-inch straight shank, including benchtop drill presses and portable electric or pneumatic drills.

Installation Notes

Secure the shank fully in the chuck and verify concentricity before drilling to minimize runout. For drilling metals, apply cutting fluid to extend bit life and reduce heat buildup. Always wear appropriate eye protection and secure the workpiece before starting the drill. Discard or resharpen bits showing chipped edges, bluing from overheating, or reduced cutting performance.
