Value Collection BS26N0021 Jobber Drill Bit No. 21 Hss

Product Description

The VALUE COLLECTION BS26N0021 is a No. 21 wire-size jobber-length drill bit designed for general-purpose drilling in a wide range of materials. Made 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 0.1590 inches in diameter, and the overall length is 3.25 inches. Right-hand cutting direction follows standard convention for use in conventional drill presses, hand drills, and CNC setups. This bit is sold individually and is suited for shop, maintenance, and production environments.

This jobber drill bit is appropriate for drilling steel, aluminum, non-ferrous metals, and wood. The 2.125-inch flute length provides adequate chip clearance for through-hole and blind-hole work in typical material thicknesses encountered in fabrication, maintenance, and light manufacturing. The general-purpose grade and ANSI specification designation make it a reliable option for professionals who need a standard wire-size bit without specialty coatings or point geometry.

Key Features

• No. 21 wire size with a decimal diameter of 0.1590 inches
• 140-degree point angle for reduced walking and lower entry force
• High speed steel construction for durability across ferrous and non-ferrous materials
• Fast spiral flute with web thinning and tapered web configuration for efficient chip evacuation
• Bright/uncoated finish — no coating buildup to affect hole diameter tolerances
• Right-hand cutting, straight shank — compatible with standard drill chucks
• ANSI specification compliant, general-purpose grade

Compatibility

Designed as a general-purpose jobber-length drill bit for use in standard three-jaw drill chucks accepting a 0.1590-inch straight shank, including hand drills, drill presses, and CNC drilling equipment.

Installation Notes

Secure the shank fully in the drill chuck before operation and confirm the bit runs true before engaging the workpiece. Clamp workpieces firmly to prevent walking at entry, particularly in metal applications. Apply cutting fluid when drilling ferrous metals to extend bit life and improve hole quality. Replace the bit when point dulling causes excessive heat buildup or oversized holes.
