Value Collection BS27N0040 No. 40 Hss Jobber Drill Bit

Product Description

The VALUE COLLECTION BS27N0040 is a No. 40 wire-size jobber-length drill bit ground from high speed steel (HSS) and left in a bright, uncoated finish. It produces a 0.0980-inch diameter hole with a 130-degree split-point geometry that reduces walking and improves bite on entry. The slow-spiral flute design clears chips efficiently in aluminum and other non-ferrous materials. Overall length is 2.375 inches, with a 1.375-inch flute length, and the straight cylindrical shank matches the decimal diameter of 0.0980 inches for secure chuck seating. It is a general-purpose bit suited for hand drilling, drill press, and CNC work where a standard wire-gauge size is specified.

This bit is rated for aluminum and non-ferrous workpiece materials, making it a practical choice for sheet metal fabrication, electrical rough-in drilling through aluminum panels, HVAC equipment assembly, and light mechanical work. The 130-degree point angle and slow-spiral flute are well matched to soft-metal applications where a conventional 118-degree bit may grab or chatter. Right-hand cutting direction is standard for all common drill equipment. The web-thinned, tapered web configuration reduces thrust load at the tip.

Key Features

• No. 40 wire size, 0.0980-inch diameter for precise hole sizing in aluminum and non-ferrous stock
• 130-degree point angle with web thinning reduces entry walking and lowers thrust requirements
• Slow-spiral flute geometry promotes controlled chip evacuation in soft metals
• High speed steel construction provides hardness and wear resistance for general-purpose use
• Bright, uncoated finish allows easy visual inspection of cutting-edge condition
• Straight cylindrical shank seats securely in standard keyless or keyed chucks

Compatibility

Designed as a general-purpose replacement or stock bit for applications requiring a No. 40 wire-gauge drill in aluminum and non-ferrous materials; conforms to ANSI specification designation for jobber-length drill geometry.

Installation Notes

A licensed machinist, electrician, or qualified trade professional should secure the shank fully within the chuck before operation and verify runout is within acceptable tolerance. Disconnect or de-energize all equipment being drilled into before starting. Use cutting fluid or lubricant when drilling aluminum at higher speeds to extend cutting-edge life. Inspect the cutting edges before each use and replace the bit if chipping or dulling is observed.
