Import BDNA-KP65104 Jobber Drill Bit Letter C Hss

Product Description

The IMPORT BDNA-KP65104 is a jobber-length twist drill bit sized to Letter C (0.2420 inches) and manufactured from high speed steel with an oxide coating. It features a 118-degree standard point angle, a right-hand spiral flute, and a straight cylindrical shank. The overall length is 4 inches with a flute length of 2.75 inches. This bit is suited for general-purpose drilling in metal, wood, and plastics and is a standard consumable stocked by machinists, maintenance technicians, pipefitters, and general trade contractors who need reliable through-hole capability in a common letter-size format.

This drill bit fits general-purpose applications where a Letter C diameter hole is required. Common use cases include pilot holes for fasteners, clearance holes in sheet metal and structural steel, and layout drilling in fabrication shops. The regular spiral flute and tapered web configuration with web thinning support efficient chip evacuation and reduced thrust in hand-drill and drill-press applications alike. It is sold individually and is appropriate for both bench use and field service kits.

Key Features

• Letter C size — 0.2420 inches diameter for precise fit in standard letter-series hole charts
• 118-degree standard point angle with web-thinned, tapered web for reduced entry thrust
• High speed steel construction for hardness and heat resistance in general-purpose drilling
• Oxide finish coating provides mild corrosion resistance and reduces friction at the cutting edge
• Right-hand cut, regular spiral flute promotes efficient chip removal
• Straight cylindrical shank compatible with standard 3-jaw drill chucks

Compatibility

Designed as a general-purpose jobber-length drill bit compatible with any standard 3-jaw keyed or keyless drill chuck that accepts a straight cylindrical shank at 0.2420 inches diameter.

Installation Notes

A licensed machinist or qualified tradesperson should secure the bit fully in the chuck before operation and verify concentricity before drilling. Always wear appropriate eye protection and secure the workpiece to prevent rotation. For drilling ferrous metals, use an appropriate cutting fluid to extend bit life and control heat buildup. Inspect the cutting edges and point for wear or chipping before each use and replace if the geometry is compromised.
