Value Collection 01378405 Cobalt Drill Bit Size 40

Product Description

The VALUE COLLECTION 01378405 is a cobalt screw machine length drill bit designed for high-speed drilling in tough materials. Built in wire gauge size 40 with a decimal diameter of 0.0980 inches, this bit features a 135-degree split point that self-centers on contact and reduces walking on hard surfaces. The shortened screw machine length overall length of 1-13/16 inches provides added rigidity, making it well suited for use in drill presses, CNC machines, and turret lathes where stub-length stability is required. It ships with a straw finish and uncoated cutting edges, standard for cobalt heavy-duty tooling.

This drill bit is sized for wire gauge 40 applications and falls within the 0.0000 to 0.1000 inch drill bit size range. It is commonly used in metalworking and machining environments for drilling ferrous metals, stainless steel, cast iron, and other hard alloys. The screw machine length format is a standard choice for production drilling and repetitive hole operations on machine tools where a shorter bit reduces deflection and improves hole accuracy.

Key Features

• Cobalt tool material rated for heavy-duty drilling in hardened and abrasive metals
• 135-degree split point self-centers and reduces thrust force at entry
• Screw machine length body at 1-13/16 inches overall for maximum rigidity
• Flute length of 13/16 inches supports efficient chip evacuation in short-depth holes
• Right-hand cutting direction, straight shank, regular spiral flute
• 2-flute geometry standard for general metalworking drill applications

Compatibility

Designed as an OEM-style replacement or direct-use bit for any drill press, CNC turret, or hand drill accepting a straight shank wire gauge 40 bit within the 0.0000 to 0.1000 inch size range.

Installation Notes

Installation of this drill bit is performed by qualified machinists or tool-and-die professionals. Power down and de-energize all machinery before changing tooling. Secure the straight shank fully in the chuck or collet to the recommended engagement depth for the machine being used. Follow applicable shop safety standards and machine manufacturer guidelines for spindle speed and feed rate selection based on material being drilled.
