Value Collection 01180165 Letter E Hss Jobber Drill Bit

Product Description

The VALUE COLLECTION 01180165 is a Letter E jobber-length drill bit sized at 0.2500 inches (1/4 inch) in diameter, ground to a 118-degree standard point angle. Manufactured from high speed steel (HSS) with an oxide coating for added surface hardness and corrosion resistance, this bit is built for general-purpose drilling in steel and cast iron. The web-thinned, tapered web design reduces thrust and improves chip clearance at the cutting tip. With an overall length of 4 inches and a 2.75-inch flute length, it fits standard drill chucks and drill presses used in fabrication, maintenance, and production environments.

This jobber drill bit is suited for drilling ferrous metals including mild steel and cast iron in both light manufacturing and maintenance-repair operations. The straight cylindrical shank with a 0.2500-inch diameter seats securely in keyed or keyless chucks. The regular spiral flute geometry provides efficient chip evacuation during standard feed-rate drilling. Machinists, millwrights, and maintenance technicians commonly use this size for clearance holes, pilot holes, and through-hole operations on structural and machine components.

Compatibility

Designed as a general-purpose jobber drill bit for use in standard drill presses, hand drills, and machining centers accepting a 1/4-inch straight shank. Primary workpiece materials are steel and cast iron.

Installation Notes

Install and remove drill bits only with the drill or drill press powered off and the chuck key removed from the chuck. Secure the workpiece with appropriate clamping before drilling to prevent rotation. Use cutting fluid or coolant when drilling steel to extend tool life and maintain dimensional accuracy. Inspect the cutting edges for wear or chipping before each use and replace the bit if the point shows signs of damage.
