Value Collection 01378488 Cobalt Drill Bit Size 48

Product Description

The VALUE COLLECTION 01378488 is a cobalt screw machine length drill bit sized to wire gauge 48, equivalent to 0.076 inches in decimal diameter. The 135-degree split point geometry reduces walking and allows faster penetration without a center punch in most applications. At 1-11/16 inches overall length, this short-series bit provides added rigidity and reduced deflection in tight drilling situations. The straight shank fits standard drill chucks and machine tool holders. Two regular spiral flutes clear chips efficiently. This bit is intended for use by machinists, tool-and-die workers, and maintenance technicians drilling in metal substrates.

Screw machine length bits are standard in CNC turret drilling, bench drill press work, and manual machining operations where stub-length rigidity is preferred over jobber-length reach. The 0.076-inch diameter is commonly used for tapping prep in small-fastener applications. The cobalt construction makes this bit suitable for drilling harder ferrous alloys, stainless steel, and heat-resistant materials that would quickly degrade high-speed steel tooling. The heavy-duty grade designation indicates suitability for production drilling environments.

Key Features

• Cobalt construction for drilling hardened ferrous metals and stainless steel
• 135-degree split point reduces drill walk and decreases required feed force
• Screw machine (stub) length provides increased rigidity and reduced deflection
• Two regular spiral flutes for consistent chip evacuation
• Straight shank fits standard drill chucks and collet holders
• Heavy-duty grade rated for production and repeat-cycle drilling

Compatibility

Designed as an OEM-style replacement or direct substitute for wire gauge 48 screw machine length drill bits used in standard drill press, CNC turret, and hand-held drill applications accepting straight-shank tooling.

Installation Notes

Secure the straight shank firmly in the chuck or collet before operation. Use appropriate cutting fluid or coolant when drilling hardened or stainless alloys to extend tool life, even though this bit does not support coolant-through delivery. Follow applicable shop safety standards and machine guarding requirements. Inspect the cutting edges before each use and discard or resharpen bits showing chipping or wear at the split point.
