Value Collection 01198274 Cobalt Jobber Drill Bit No. 27

Product Description

The VALUE COLLECTION 01198274 is a cobalt jobber-length drill bit sized to wire gauge No. 27 (0.1440 inches) with a 135-degree split-point tip. Cobalt construction gives this bit the heat resistance and edge retention needed when drilling stainless steel, hardened alloys, and other tough ferrous materials. The split-point geometry starts on contact without a center punch, reducing walking on hard surfaces. With a 3-inch overall length and a 1.875-inch flute length, this is a standard jobber format suited to handheld drills, drill presses, and CNC setups. It is sold individually and is intended for professional machining, fabrication, and maintenance applications.

This bit is engineered primarily for stainless steel and hardened materials where high-speed steel bits lose their edge quickly. Typical use cases include drilling fastener clearance holes, tapping pilot holes, and production drilling in sheet metal or structural components. The straight cylindrical shank fits standard three-jaw chucks without modification. The regular spiral flute pattern evacuates chips efficiently in through-hole and blind-hole operations. Fabricators, machinists, and maintenance technicians working in industrial and commercial environments are the primary users of this bit.

Key Features

• No. 27 wire gauge size — 0.1440 inches decimal equivalent
• 1.875-inch flute length supports efficient chip evacuation in deep holes
• Straight cylindrical shank fits standard drill chucks without adapters
• Right-hand cutting direction, regular spiral flute, two flutes

Compatibility

Designed as an OEM-style replacement or direct-use cobalt jobber drill bit for standard three-jaw drill chucks accepting a 0.1440-inch straight shank, compatible with handheld drills, drill presses, and CNC drilling equipment.

Installation Notes

Installation is performed by machinists or fabricators with appropriate drilling equipment. Secure the shank fully in the chuck before operation and verify chuck key removal prior to powering the spindle. Use cutting fluid or coolant when drilling stainless steel or hardened materials to extend bit life and prevent work hardening at the cutting zone. Do not apply excessive feed pressure — let the split-point geometry and cobalt hardness do the work.
