Value Collection 01166149 Letter N Jobber Drill Bit Hss

Product Description

The VALUE COLLECTION 01166149 is a Letter N jobber-length drill bit designed for general-purpose drilling in production and maintenance environments. Manufactured from high speed steel (HSS) with a bright, uncoated finish, it features a standard 118-degree point angle and a regular spiral flute for efficient chip evacuation. The straight cylindrical shank measures 0.3020 inches in diameter, and the overall length is 4.375 inches with a flute length of 3.0625 inches. Right-hand cutting direction and a web-thinned, tapered web configuration reduce entry force and improve centering on startup. Licensed tradespeople and machining professionals install this bit in standard drill presses, hand drills, and CNC equipment.

This jobber drill bit is suited for drilling aluminum, non-ferrous metals, plastics, and other softer materials where an HSS bit performs reliably without the added cost of coated tooling. The Letter N designation corresponds to a decimal diameter of 0.3020 inches, placing it in the 0.3000 to 0.3500 inch size range. It is a practical choice for shops, maintenance crews, and field technicians who need a dependable general-purpose drill in a common letter-size designation. Each unit is sold individually, with a minimum order quantity of 6 pieces per order.

Key Features

• 118-degree standard point angle for general-purpose entry on non-ferrous materials
• High speed steel construction for durability across repeated use cycles
• Bright, uncoated finish — no coating buildup to affect tolerance-critical holes
• Web-thinned tapered web reduces thrust and improves self-centering
• Regular spiral, 2-flute design promotes consistent chip clearance

Compatibility

Designed as a general-purpose jobber-length drill bit compatible with standard 3-jaw drill chucks and collet systems accepting a 0.3020-inch straight shank. Intended for use in aluminum and non-ferrous workpiece materials as noted in the product specifications.

Installation Notes

Install in a drill press, hand drill, or CNC spindle with a chuck rated for the 0.3020-inch straight shank diameter. Secure the shank firmly to prevent slipping and verify chuck runout before drilling precision holes. Follow standard machine guarding and PPE requirements per shop safety protocols. Replace the bit when point wear causes increased thrust force or noticeable wandering at entry.
