Value Collection 01378157 Size 15 Cobalt Drill Bit

Product Description

The VALUE COLLECTION 01378157 is a screw machine length cobalt drill bit designed for high-speed drilling in hard and abrasive materials. Built to heavy-duty grade standards, it features a 135-degree split point that reduces walking on contact and allows drilling to start without a center punch. The cobalt construction provides superior heat resistance compared to standard high-speed steel, making it suitable for stainless steel, cast iron, and other tough alloys. At 2-3/16 inches overall length, the shorter screw machine body delivers added rigidity in confined spaces and reduces deflection during high-feed drilling operations.

This drill bit is intended for use in screw machine and production drilling applications where a compact, stiff tool is required. It is well suited for metal fabrication shops, maintenance and repair operations, and production line environments. The straight shank accepts standard drill chucks on hand drills, drill presses, and CNC machining centers. Right-hand cutting direction is standard for conventional clockwise-rotating spindles. The regular spiral flute geometry promotes efficient chip evacuation in most metal drilling scenarios.

Key Features

• Cobalt construction for heat resistance and extended tool life in hard metals
• 135-degree split point reduces thrust and eliminates center-punch requirement
• Screw machine length body increases rigidity and reduces deflection
• Right-hand cutting, regular spiral flutes for efficient chip removal
• Straight shank fits standard drill chucks without adapters
• Heavy-duty drill bit grade rated for demanding production applications

Compatibility

Designed as an OEM-style replacement or production-use drill bit compatible with standard drill chucks accepting straight shank tooling across hand drills, drill presses, and CNC machining centers using conventional right-hand rotation.

Installation Notes

Installation and use should be performed by qualified machinists or trade professionals familiar with drill press and machining center operation. Secure the workpiece firmly before drilling and confirm spindle speed is appropriate for the material and bit diameter before starting. Do not apply side pressure to the bit during drilling as screw machine length bits, while rigid, are not designed for lateral loading. Inspect the cutting edges before each use and replace if chipping or excessive wear is observed.
