Value Collection KP65112 Jobber Drill Bit Letter K Hss

Product Description

The VALUE COLLECTION KP65112 is a jobber length drill bit sized to Letter K (0.2810 inches decimal equivalent), designed for general-purpose drilling in metal, wood, and plastic. It is made from high speed steel (HSS) with an oxide coating for added wear resistance and heat reduction during cutting. The bit features a 118-degree standard point angle, a right-hand spiral flute with regular helix, and a straight-cylindrical shank. Overall length is 4.25 inches with a flute length of 2.9375 inches. Machinists, maintenance technicians, and fabricators will find this bit suited for everyday production and repair drilling tasks.

This drill bit is intended for use in standard drill presses, hand drills, and CNC machines accepting a straight shank. It fits applications requiring a Letter K diameter hole, common in tapping operations for thread sizes that call for a 0.281-inch pilot. The web-thinned, tapered web construction reduces thrust when starting and progressing through material, making it practical for both high-volume production and intermittent shop use.

Key Features

• Letter K size with 0.2810-inch decimal equivalent for precise hole sizing
• 118-degree standard point angle with web-thinned, tapered web for reduced thrust
• High speed steel construction with oxide coating for improved wear and heat resistance
• Right-hand cut with regular spiral flute for efficient chip evacuation
• Straight-cylindrical shank fits standard drill chucks without adapters
• General-purpose grade suitable for metal, wood, and plastic applications

Compatibility

Designed as a general-purpose jobber length drill bit compatible with standard drill chucks accepting a 0.2810-inch straight-cylindrical shank, including drill presses, hand drills, and CNC spindles within the 0.2500 to 0.3000-inch drill bit size range.

Installation Notes

Installation is performed by machinists or maintenance technicians using a standard keyed or keyless drill chuck. Secure the shank fully in the chuck before operation and verify the workpiece is clamped or fixtured to prevent rotation. Inspect the cutting edges for wear or chipping before each use, and replace the bit if the point is dull to avoid overheating the workpiece or workholding setup.
