Value Collection 01378231 Cobalt Drill Bit Size 23

Product Description

The VALUE COLLECTION 01378231 is a cobalt screw machine length drill bit designed for high-speed, short-clearance drilling in metal fabrication and machining applications. Built from cobalt high-speed steel, this bit delivers superior heat and wear resistance compared to standard HSS tooling. It features a 135-degree split point for fast, self-centering starts without the need for a center punch. At 2-1/16 inches overall length, the screw machine format fits tight-access drilling situations and is suited for use in drill presses, CNC machines, and hand-held power tools. The 0.154-inch diameter corresponds to wire gauge size 23. This is a right-hand cutting, straight-shank bit with a regular spiral flute and a heavy-duty grade rating.

This drill bit is used in production and maintenance environments where repeated drilling into steel, stainless steel, cast iron, and other hard metals is required. The screw machine length format is common in shop floors, tool cribs, and field service kits where stub-length rigidity is preferred over jobber-length flex. Machinists, tool-and-die technicians, and maintenance mechanics are the primary users. It is sold individually but requires a minimum order of 12 units per purchase.

Key Features

• Cobalt high-speed steel construction for extended tool life in hard and abrasive materials
• 135-degree split point reduces walking and cutting pressure at entry
• Screw machine length provides added rigidity over standard jobber-length bits
• Right-hand cutting with regular spiral flutes for efficient chip evacuation
• Straight shank compatible with standard drill chucks
• Heavy-duty grade rating suitable for production drilling cycles

Compatibility

Designed as an OEM-style replacement or production-use drill bit for applications requiring a wire gauge size 23 diameter within the 0.150 to 0.200 inch decimal inch range, fitting standard straight-shank drill chucks.

Installation Notes

Installation and use of this drill bit should be performed by qualified machinists or maintenance technicians familiar with metal cutting operations. Ensure the drill chuck is fully tightened and the workpiece is securely fixtured before beginning any cut. Always use appropriate cutting fluid or coolant when drilling hard metals to extend bit life, noting this bit does not support coolant-through delivery. Inspect the cutting edges for wear or chipping before each use and replace when performance degrades.
