Value Collection 01378140 Cobalt Drill Bit Size 14

Product Description

The VALUE COLLECTION 01378140 is a cobalt screw machine length drill bit designed for high-speed drilling in tough materials including hardened steel, stainless steel, and heat-resistant alloys. Built to a wire gauge Size 14 with a decimal equivalent of 0.1820 inches, this bit features a 135-degree split point that reduces walking on entry and requires no center punch on most surfaces. The shortened screw machine length body — 2.1875 inches overall — provides added rigidity in drill press, turret lathe, and CNC applications where stub-length tooling is preferred. A standard straight shank and two-flute regular spiral design make this compatible with most chucks and collet holders. Machinists, tool and die tradespeople, and production drilling operators are the primary users.

This bit is suited for production and job-shop environments where precise, repeatable hole sizing in the 0.1500 to 0.2000 inch decimal range is required. It performs well in drill presses, milling machines, and hand-held drill motors where a rigid, short-length bit reduces deflection in interrupted cuts or when drilling at depth. The cobalt construction with straw finish handles elevated cutting temperatures without premature edge breakdown, making it a practical choice for ferrous metals, exotic alloys, and work-hardening materials that consume high-speed steel tooling quickly.

Key Features

• Cobalt tool material for extended tool life in hard and abrasive materials
• 135-degree split point reduces entry thrust and eliminates center-punch requirement on most workpieces
• Screw machine length body at 2.1875 inches OAL provides rigidity and reduces deflection
• Straight shank fits standard drill chucks and collet holders without modification
• Right-hand cutting direction, regular spiral flute for efficient chip evacuation
• Heavy duty grade rated for production drilling applications

Compatibility

Designed as a standard screw machine length drill bit for use in drill presses, CNC machining centers, turret lathes, and hand-held drill motors accepting straight shank tooling in the 0.1500 to 0.2000 inch decimal inch size range.

Installation Notes

Secure the shank fully in the chuck or collet and verify runout before beginning a cut. Use appropriate cutting fluid or coolant when drilling ferrous and work-hardening materials to extend edge life, noting that this bit does not support through-coolant delivery. Inspect the cutting edges and split point for chipping before each use; a damaged split point increases thrust and reduces hole accuracy. Wear appropriate PPE including eye protection when operating any drill tooling.
