Value Collection 01167311 No. 31 Hss Jobber Drill Bit

Product Description

The VALUE COLLECTION 01167311 is a wire gauge No. 31 jobber-length drill bit ground from high speed steel (HSS) with a standard 118-degree split point and a bright, uncoated finish. At 0.1200 inches in diameter and 2.75 inches overall length, this bit is sized for general-purpose drilling in light metals, plastics, and non-ferrous materials. The straight cylindrical shank seats securely in standard 3-jaw drill chucks. A web-thinned, tapered web construction reduces thrust and improves chip flow at the cutting edge. Machinists, maintenance technicians, and sheet-metal workers are the primary users of this size range.

The 01167311 is suited for production and maintenance drilling in aluminum, copper, brass, and other non-ferrous workpiece materials. Its 1.625-inch regular spiral flute length provides adequate chip evacuation in through-hole and blind-hole applications at typical hand-drill or drill-press feed rates. The right-hand cutting geometry is standard for conventional clockwise-rotation spindles found on drill presses, CNC machines, and cordless drill drivers.

Key Features

• Wire gauge No. 31 — 0.1200-inch diameter for precision hole sizing
• 118-degree standard point angle for general-purpose drilling
• High speed steel construction provides good hardness and wear resistance for non-ferrous materials
• Bright, uncoated finish — no coating to flake or contaminate workpiece
• Web-thinned tapered web reduces cutting thrust and improves chip removal
• Regular spiral, right-hand flute geometry compatible with standard clockwise-rotation spindles

Compatibility

Designed as a general-purpose jobber drill bit for use in standard 3-jaw drill chucks accepting a 0.1200-inch straight cylindrical shank, suitable for drill presses, hand drills, and CNC drill spindles within the 0.1000- to 0.1500-inch drill size range.

Installation Notes

Installation is performed by machinists or maintenance technicians using a standard drill chuck. Secure the shank fully in the chuck before operation and confirm the chuck key is removed before starting the spindle. Use appropriate cutting fluid or lubricant for non-ferrous metals to extend bit life and improve hole finish. Inspect the cutting edges for wear or chipping before each use and replace bits that show visible damage to avoid workpiece surface defects.
