Value Collection 01378256 Cobalt Drill Bit Size 25

Product Description

The VALUE COLLECTION 01378256 is a cobalt screw machine length 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 entry and requires less feed pressure to start the cut. The straight shank and short screw machine length body make it well suited for use in tight clearances and production environments. At 0.1495 inches in diameter, it corresponds to wire gauge size 25 and delivers consistent hole geometry in steel, stainless, cast iron, and similar tough workpiece materials.

This drill bit is used in metalworking applications across manufacturing, maintenance, and fabrication settings. The screw machine length profile fits standard drill chucks and is commonly run in drill presses, CNC machining centers, and hand-held power drills where a shorter, stiffer bit improves accuracy and reduces deflection. It is suited for production drilling in ferrous metals, heat-treated alloys, and other materials that cause premature wear in standard high-speed steel tooling. Licensed machinists, toolmakers, and maintenance mechanics are the primary users.

Key Features

• Cobalt construction provides elevated heat and wear resistance for drilling hard metals
• 135-degree split point reduces drill walking and lowers required feed pressure
• Screw machine length body increases rigidity and reduces deflection in tight setups
• Right-hand cutting direction for standard clockwise drill operation
• 2-flute regular spiral flute design promotes efficient chip evacuation
• Straight shank fits standard drill chucks without adapters

Compatibility

Designed as a standard screw machine length drill bit in wire gauge size 25, compatible with any drill chuck or collet system that accepts a straight shank at 0.1495 inches nominal diameter.

Installation Notes

This bit is installed by a machinist or maintenance technician in any standard drill chuck capable of accepting a straight shank. Ensure the workpiece is securely clamped before drilling and use appropriate cutting fluid when drilling hard alloys to extend tool life. Inspect the split point for chipping before each use, as a damaged point will affect hole accuracy and can cause bit breakage under feed pressure.
