Value Collection BS260000B Jobber Drill Bit Letter B Hss

Product Description

The VALUE COLLECTION BS260000B is a letter-size B jobber-length drill bit designed for general-purpose drilling in production and maintenance applications. Manufactured from high-speed steel (HSS) with a bright/uncoated finish, it features a 140-degree split point and a fast spiral flute geometry with web thinning for reduced thrust and cleaner entry. The straight cylindrical shank measures 0.2380 inches in diameter, matching the drill diameter for direct chuck mounting. At 4.0000 inches overall length with a 2.7500-inch flute length, this bit suits standard benchtop drill presses, hand drills, and CNC drilling operations. It is installed and used by machinists, maintenance technicians, and fabricators.

This jobber drill is suited for through-hole and blind-hole drilling in steel, aluminum, non-ferrous metals, and wood. The fast spiral flute promotes efficient chip evacuation, making it effective in both ferrous and non-ferrous materials. The 140-degree point angle provides self-centering capability, reducing the need for a center punch on many workpiece materials. It is a solid choice for general shop use, field maintenance, and light production drilling where a standard HSS bit is specified.

Key Features

• Letter B size: 0.2380 inch diameter for precise hole sizing
• 140-degree standard point angle with web thinning for reduced entry force
• Fast spiral flute with tapered web configuration for efficient chip removal
• High-speed steel construction handles steel, aluminum, non-ferrous metals, and wood
• Bright/uncoated finish — no coating buildup to affect dimensional tolerance
• Right-hand cutting, 2-flute design conforming to ANSI specification

Compatibility

Designed as a general-purpose jobber drill for use in any standard drill press, hand drill, or CNC spindle accepting a 0.2380-inch straight cylindrical shank. Suitable for workpiece materials including steel, aluminum, non-ferrous alloys, and wood.

Installation Notes

A licensed machinist or qualified technician should secure the straight shank firmly in a keyed or keyless chuck before operation, verifying concentricity to minimize runout. Ensure the workpiece is properly clamped or fixtured before drilling to prevent movement. Use appropriate cutting fluid or lubricant when drilling ferrous metals to extend tool life. Inspect the cutting edges for wear before each use and replace the bit if chipping or dulling is observed.
