Value Collection 01378470 Size 47 Cobalt Drill Bit

Product Description

The VALUE COLLECTION 01378470 is a screw machine length cobalt drill bit designed for high-speed drilling in tough materials. Built from heavy-duty cobalt steel, it handles hard metals, stainless, and abrasive alloys that would wear out standard high-speed steel bits. The 135-degree split point starts on contact without a center punch and reduces thrust load during entry. At 0.0785 inches in diameter (wire gauge size 47) with a 1.75-inch overall length, this stub-length bit runs with minimal deflection and is well suited to close-quarters drilling in production and repair environments.

Screw machine length bits like the 01378470 are standard on turret lathes, CNC drill presses, multi-spindle machines, and hand-held drilling operations where a shorter, stiffer bit improves hole accuracy. The right-hand cutting direction and regular spiral flute pattern make this bit a straightforward fit for general metalworking, toolroom work, automotive repair, and MRO production drilling. A 0.75-inch flute length keeps chip evacuation manageable in shallow-to-medium depth holes typical of this size range.

Key Features

• Cobalt construction for extended tool life in hard and abrasive metals
• 135-degree split point for self-centering entry and reduced walking
• Stub screw machine length (1.75 inches OAL) minimizes deflection and maximizes rigidity
• Right-hand cut with regular spiral flute for reliable chip clearance
• Straight shank compatible with standard drill chucks and collets
• Heavy-duty grade rated for demanding production and MRO applications

Compatibility

Designed as an OEM-style replacement or standard production drill bit for use in any drilling application requiring a wire gauge size 47 straight-shank screw machine length bit.

Installation Notes

Installation and use of this drill bit should be performed by a qualified machinist or maintenance technician familiar with drill press, lathe, or hand-drill operation. Secure the straight shank firmly in a properly sized chuck or collet before operation and verify runout is within acceptable tolerance for the application. Use appropriate cutting fluid for the material being drilled to extend tool life and improve hole finish. Always wear appropriate eye protection and follow applicable shop safety procedures when drilling.
