Value Collection 01378546 Cobalt Drill Bit Size 54

Product Description

The VALUE COLLECTION 01378546 is a cobalt screw machine length drill bit sized at wire gauge 54 (0.0550 inches decimal) with a 135-degree split point. Built for heavy-duty use, it features a straight shank, right-hand cutting direction, and a straw finish. The shortened screw machine length overall length of 1-5/8 inches makes it well suited for work in confined spaces and high-cycle production drilling. With 2 regular spiral flutes and a 5/8-inch flute length, this bit handles tough materials common in metalworking and fabrication. Machinists, tool-and-die technicians, and maintenance mechanics are the typical users.

This drill bit is appropriate for drilling small-diameter holes in ferrous metals, stainless steel, and other hard materials where a high-speed steel bit may wear prematurely. Screw machine length bits are commonly used in drill presses, CNC machining centers, and manual lathes where reduced length increases rigidity and minimizes deflection. The 135-degree split point geometry reduces walking on entry and requires less feed pressure, making it practical for production environments and precision work alike.

Key Features

• Wire gauge size 54 with 0.0550 inch decimal diameter for precise small-hole drilling
• 135-degree split point reduces bit walking and lowers required feed force
• Cobalt construction rated for heavy-duty use in hard and abrasive materials
• Screw machine length (1-5/8 inches OAL) increases rigidity and reduces deflection
• Right-hand cutting, 2-flute regular spiral design for standard drilling applications
• Straight shank compatible with standard drill chucks and collets

Compatibility

Designed as an OEM-style replacement or direct-use screw machine length drill bit for wire gauge size 54 applications across standard drill presses, machining centers, and hand-held power drills equipped with a compatible straight-shank chuck.

Installation Notes

Installation and use of this drill bit should be performed by qualified machinists or maintenance personnel familiar with machine tool operation. Secure the straight shank fully in the chuck or collet before operation and confirm the machine is at a complete stop before changing bits. Use appropriate cutting fluid or lubrication when drilling hard metals to extend bit life and improve hole quality. Follow applicable shop safety standards and machine manufacturer guidelines for speed and feed settings.
