Value Collection 01378181 Cobalt Drill Bit Size 18

Product Description

The VALUE COLLECTION 01378181 is a cobalt screw machine length drill bit designed for high-performance drilling in hard and abrasive materials. Built to a Size 18 wire gauge dimension (0.1695 inches), this bit features a 135-degree split point that reduces walking on contact and allows drilling to begin without a center punch on most surfaces. The shortened screw machine length overall length of 2.125 inches provides added rigidity compared to jobber-length bits, making it well suited for drilling in confined spaces or on drill presses where chatter and deflection need to be minimized. Cobalt construction provides heat resistance and wear life beyond standard high-speed steel bits.

This drill bit is intended for use in metal fabrication, machine shops, maintenance and repair operations, and industrial production environments. It is particularly effective when drilling stainless steel, hardened alloys, cast iron, and other tough ferrous metals. The straight shank is compatible with standard drill chucks found on drill presses, CNC machines, and hand-held power drills. The regular spiral flute design promotes efficient chip evacuation during through-hole drilling operations.

Key Features

• Cobalt tool material provides superior heat and wear resistance compared to standard HSS bits
• 135-degree split point reduces thrust force and minimizes bit walking on entry
• Screw machine length body adds rigidity and reduces deflection in tight setups
• Right-hand cutting direction compatible with all standard drill chucks and spindles
• 2-flute regular spiral design promotes consistent chip removal
• Heavy duty grade construction suited for repeated use in production drilling

Compatibility

Designed as a standard screw machine length drill bit with a straight shank for use in any drill chuck accepting bits in the 0.1500 to 0.2000 inch diameter range, including drill presses, CNC drilling machines, and hand-held power drills.

Installation Notes

This bit is installed by a machinist or maintenance technician into a keyed or keyless drill chuck. Ensure the machine is fully powered down and the spindle is locked before changing bits. Secure the shank firmly in the chuck to the full depth of the jaws to prevent slippage under load. Use appropriate cutting fluid when drilling hardened or stainless alloys to extend bit life and improve hole finish.
