Value Collection 01430479 Extra Length Drill Bit Hss

Product Description

The VALUE COLLECTION 01430479 is a high speed steel extra length drill bit designed for drilling applications that require extended reach beyond the capacity of standard-length bits. With a 0.7344-inch diameter, a 118-degree standard point angle, and an overall length of 12 inches, this bit handles deep-hole drilling in metal, wood, and plastics where a conventional bit cannot reach. The oxide finish reduces friction and provides basic corrosion resistance during storage and use. Two spiral flutes with a web-thinned, tapered web configuration improve chip evacuation and reduce the thrust required to start and advance the cut.

This bit is suited for general-purpose drilling tasks performed by machinists, fabricators, and maintenance technicians working with drill presses, lathes, or hand-held power drills. The 9-inch flute length provides extended chip clearance in deep-hole applications. The straight-cylindrical shank with a 47/64-inch diameter seats securely in standard drill chucks and collet holders. Right-hand cutting direction is standard for conventional drilling operations.

Key Features

• High speed steel construction for general-purpose drilling in metal, wood, and plastics
• 118-degree standard point angle with web-thinned tapered web for reduced entry thrust
• 12-inch overall length with 9-inch flute length for extended-reach drilling
• Oxide finish reduces surface friction and provides basic rust protection
• Two-flute spiral design promotes efficient chip evacuation in deep holes
• Straight-cylindrical shank compatible with standard drill chucks and collet holders

Compatibility

Designed as a general-purpose extra length drill bit for use in standard drill chucks and collet holders that accept a straight-cylindrical shank of 47/64-inch diameter.

Installation Notes

Installation and use should be performed by qualified machinists or maintenance technicians familiar with drilling equipment and safe operating practices. Secure the workpiece firmly before drilling and confirm the chuck or collet is properly tightened on the straight shank before starting the spindle. Reduce feed pressure when the bit begins to break through the far side of the workpiece to prevent grabbing. Inspect the cutting edges for wear or chipping before each use, and replace the bit if the point shows signs of damage that cannot be corrected by standard sharpening.
