Value Collection BS26N0051 No. 51 Hss Jobber Drill Bit

Product Description

The VALUE COLLECTION BS26N0051 is a No. 51 wire-gauge jobber-length drill bit manufactured from high speed steel (HSS) with a bright, uncoated finish. The bit measures 0.0670 inches in diameter and 2 inches overall, with a 1-inch flute length. A 140-degree split-point geometry reduces walking on entry and lowers thrust force, making it well suited for production drilling in steel, aluminum, and non-ferrous materials. The fast spiral flute evacuates chips efficiently, reducing heat buildup during repeated passes. This is a general-purpose bit for trade and shop applications where precision hole location and consistent sizing in small-diameter work are required.

This drill bit is used in hand-held electric drills, drill presses, and CNC drilling operations where wire-gauge sizing is specified. The No. 51 designation corresponds to 0.0670 inches, a size commonly called out in tapping charts for small machine screws and clearance holes in light sheet metal, aluminum extrusions, and hardwood. The straight cylindrical shank seats in standard three-jaw chucks without modification. Right-hand cutting direction is standard for conventional drilling operations. Sold individually; minimum order quantity is 12 units per order.

Key Features

• No. 51 wire gauge diameter: 0.0670 inches for precision small-hole drilling
• 140-degree point angle reduces bit walking and lowers required feed pressure
• Web-thinned, tapered web construction reduces cutting resistance at the chisel edge
• Fast spiral flute promotes aggressive chip evacuation in metal and wood
• Bright, uncoated HSS finish compatible with standard cutting fluids and coolants
• ANSI specification designation ensures dimensional conformance

Compatibility

Designed as a general-purpose replacement or stock drill bit for any standard three-jaw chuck accepting a 0.0670-inch straight cylindrical shank. Suitable for drilling steel, aluminum, non-ferrous metals, and wood per the manufacturer specification.

Installation Notes

Install in a three-jaw chuck and tighten securely before operation. Machinists and maintenance technicians should confirm spindle speed is appropriate for the workpiece material and bit diameter before drilling; small-diameter HSS bits are susceptible to breakage at excessive feed rates. Apply a suitable cutting fluid when drilling ferrous metals to extend bit life and improve hole finish. Inspect the cutting edges before each use and replace bits showing signs of chipping or dulling to maintain hole accuracy.
