Value Collection 01166123 Letter L Hss Jobber Drill Bit

Product Description

The VALUE COLLECTION 01166123 is a letter-size L jobber-length drill bit manufactured from high speed steel (HSS) with a bright, uncoated finish. It cuts a 0.290-inch diameter hole and features a standard 118-degree point angle suited to general-purpose drilling applications. The straight cylindrical shank seats in standard drill chucks without modification. At 4.25 inches overall length with a 2.9375-inch flute length, it fits the proportions of a standard jobber series. Right-hand spiral flutes evacuate chips efficiently during through-hole and blind-hole operations in soft and non-ferrous materials.

This bit is intended for use on aluminum, copper, brass, plastics, and other non-ferrous workpiece materials in light industrial, maintenance, and fabrication settings. The tapered web and web-thinned geometry reduce thrust force at the point, making it practical for hand-held drill use as well as drill press work. Machinists, pipefitters, sheet metal workers, and general maintenance technicians will find this size useful wherever letter-drill tolerances are called out on drawings or job specs. It is sold individually with a minimum order quantity of six units per order.

Key Features

• Letter L size: 0.290-inch diameter for applications requiring letter-drill precision
• 118-degree standard point angle for general-purpose use on non-ferrous and soft materials
• High speed steel construction provides hardness and wear resistance for repeated use
• Bright, uncoated finish — no coating buildup to affect hole diameter tolerance
• Web-thinned, tapered web construction reduces entry thrust and walking tendency
• Right-hand, regular spiral flutes with two-flute design for efficient chip evacuation

Compatibility

Designed as a general-purpose jobber drill bit compatible with any standard keyed or keyless drill chuck accepting a 0.290-inch straight cylindrical shank, including portable electric drills and bench-mounted drill presses.

Installation Notes

Secure the shank fully in the chuck jaws and tighten before operation. Use appropriate cutting fluid or lubrication when drilling non-ferrous metals to extend edge life and improve hole finish. Ensure the workpiece is clamped or fixtured to prevent rotation during drilling. Inspect the cutting edges for wear or chipping before each use; a dull or damaged bit increases thrust load and reduces hole quality.
