Value Collection 01378520 Cobalt Drill Bit Size 52

Product Description

The VALUE COLLECTION 01378520 is a cobalt screw machine length drill bit in wire gauge size 52, equivalent to 0.0635 inches in decimal. The 135-degree split point geometry reduces walking and requires less feed pressure at the start of the cut, making it well suited for production drilling and repetitive-hole applications. At 1-11/16 inches overall length, the stub-style body is stiffer than a jobber-length bit, reducing deflection in short-reach setups. Two regular spiral flutes evacuate chips efficiently. The heavy-duty cobalt construction handles elevated cutting temperatures better than standard high-speed steel, making it a practical choice for harder steels, stainless, and abrasive alloys. Installation is performed by machinists, tool-and-die workers, and general metalworking tradespeople.

This bit is designed for use in drill presses, CNC machining centers, manual mills, and handheld power drills where a short, rigid cutting tool is required. The screw machine length format is common in production environments where consistency and reduced bit flex matter across high-volume hole counts. Its 0.0635-inch diameter targets fine-detail work, pilot holes, and tapping preparation for small-diameter fasteners.

Key Features

• Wire gauge size 52 (0.0635 inches decimal) for fine-diameter drilling
• 135-degree split point reduces bit walking and lowers thrust force needed
• Cobalt construction resists heat buildup when cutting hard or abrasive metals
• Screw machine (stub) length body increases rigidity and reduces deflection
• Right-hand cutting direction, straight shank for standard chuck compatibility
• 2-flute regular spiral design promotes consistent chip evacuation

Compatibility

Designed as an OEM-style replacement or production-stock drill bit for use in any standard drill chuck or collet accepting a straight shank at 0.0635-inch diameter.

Installation Notes

Secure the straight shank firmly in a drill chuck or collet before operating. Always power down and lock out the machine spindle before changing bits. Use cutting fluid appropriate for the workpiece material to extend bit life and maintain dimensional accuracy. Operators should wear appropriate eye and hand protection in compliance with applicable shop safety standards.
