Value Collection BS260000U Jobber Drill Bit Letter U Hss

Product Description

The VALUE COLLECTION BS260000U is a jobber-length drill bit sized to letter U (0.3680 inches decimal equivalent), designed for general-purpose drilling in steel, aluminum, non-ferrous metals, and wood. The bit features a 140-degree split point with web thinning for reduced walking and lower thrust on entry. Constructed from high speed steel (HSS) with a bright uncoated finish, it runs a fast spiral flute configuration with a tapered web. The straight cylindrical shank seats directly into standard drill chucks. This bit suits machinists, fabricators, and maintenance techs who need a reliable, no-frills hole-making tool across common shop materials.

This jobber drill is built for general-purpose applications in both production and maintenance environments. The 0.3680-inch diameter places it in the 0.3500 to 0.4000 inch size range, making it appropriate for through-holes, clearance holes, and pilot operations in steel plate, aluminum stock, and wood framing. With a 5-inch overall length and 3.625-inch flute length, it provides adequate reach for most standard workpiece thicknesses without sacrificing rigidity. The fast spiral promotes efficient chip evacuation in ductile materials, reducing heat buildup during extended cuts.

Key Features

• Letter U sizing at 0.3680 inches decimal equivalent per ANSI specification
• 140-degree point angle with web thinning reduces entry thrust and prevents bit walking
• High speed steel construction rated for steel, aluminum, non-ferrous metals, and wood
• Fast spiral flute with tapered web for efficient chip removal in ductile materials
• Straight cylindrical shank fits standard drill chucks without adapters
• Bright uncoated finish — no coating to chip or flake during regrinding

Compatibility

Designed as a general-purpose jobber drill compatible with standard drill presses, hand drills, and CNC drilling equipment accepting a straight cylindrical shank at 0.3680 inches diameter.

Installation Notes

Secure the shank fully in the drill chuck and verify runout before drilling. Set spindle speed appropriate to the workpiece material and bit diameter — lower speeds for steel, higher for aluminum and wood. Use cutting fluid when drilling ferrous metals to extend bit life and reduce heat. Inspect the point geometry before use; a damaged or dull 140-degree tip should be reground or replaced before continuing work.
