Value Collection BS260000X Jobber Drill Bit Letter X Hss

Product Description

The VALUE COLLECTION BS260000X is a letter-size X jobber-length drill bit manufactured from high speed steel (HSS) with a bright, uncoated finish. It features a 140-degree split-point angle for fast entry and reduced walking on steel, aluminum, non-ferrous metals, and wood. The fast spiral flute design promotes efficient chip evacuation during drilling operations. At 5.125 inches overall length with a 3.75-inch flute, this bit fits standard drill chucks without an adapter. The web-thinned, tapered web construction reduces thrust requirements and extends cutting life in general-purpose shop and field applications. Licensed tradespeople and machinists reach for this size when drilling clearance or tap holes in ferrous and non-ferrous stock.

This drill bit is suited for residential, commercial, and light industrial drilling tasks. Its 0.3970-inch diameter corresponds to letter size X, placing it in the 0.3500 to 0.4000 inch size range. Common applications include metal fabrication, plumbing rough-in, HVAC sheet metal work, and electrical panel work where a close-tolerance hole is required. The straight cylindrical shank seats securely in keyed or keyless chucks on portable drills and drill presses. Right-hand cutting direction is standard for conventional drill press and hand-drill operation.

Key Features

• Letter X diameter (0.3970 inches) for precise clearance and tap-hole sizing
• 140-degree point angle with web thinning reduces thrust and minimizes bit walking
• Fast spiral flute geometry accelerates chip removal in metal and wood
• High speed steel construction handles steel, aluminum, non-ferrous metals, and wood
• Bright, uncoated finish allows easy visual inspection of cutting edge condition
• ANSI specification compliance ensures dimensional consistency

Compatibility

Designed as a general-purpose jobber drill bit compatible with any keyed or keyless chuck accepting a 0.3970-inch straight cylindrical shank. Primary workpiece materials include steel, aluminum, non-ferrous metals, and wood per manufacturer specification.

Installation Notes

Install and remove drill bits only when the drill or drill press is fully powered down and the chuck is stationary. Secure the workpiece with a clamp or vise before drilling to prevent rotation. Use appropriate cutting fluid when drilling ferrous metals to extend cutting edge life and manage heat. Inspect the cutting edges for wear or chipping before each use, as a dull bit increases thrust load and reduces hole quality.
