Dewalt DW1919 19/64 in Cobalt Pilot Point Drill Bit

Product Description

The DEWALT DW1919 is a cobalt mechanics drill bit engineered for demanding metal-drilling applications. It features a 135-degree split-point pilot tip that starts on contact without center-punching and reduces walking on hard surfaces. The bit is manufactured from cobalt high-speed steel, which provides heat and wear resistance when drilling through stainless steel, cast iron, and other hard metals. At 19/64 inch (0.2969 inches) in diameter and 4.375 inches overall length, it delivers a maximum drilling depth of 3.06 inches. A web-thinned, tapered-web construction reduces thrust requirements and supports chip evacuation through the spiral flute design. Licensed tradespeople and maintenance mechanics install this bit in standard three-jaw drill chucks.

This bit is suited for residential and commercial maintenance work, fabrication shops, and field service applications that require consistent performance in ferrous and non-ferrous metals. The right-hand cut and straight cylindrical shank seat securely in corded or cordless drills and drill presses. Typical use cases include hole-making in structural steel, equipment frames, HVAC sheet metal work, and mechanical systems requiring precise, clean entry points.

Key Features

• 135-degree pilot point tip eliminates center-punching and reduces bit walking
• Cobalt high-speed steel construction resists heat and wear in hard-metal drilling
• Web-thinned, tapered-web design lowers drilling thrust and improves chip clearance
• Bright uncoated finish maintains consistent dimensional tolerance without coating buildup
• 19/64 inch straight cylindrical shank fits standard drill chucks and drill press collets
• Right-hand spiral flute promotes efficient chip evacuation during through-hole drilling

Compatibility

Designed as an OEM-style replacement mechanics drill bit compatible with standard three-jaw chucks accepting a straight cylindrical shank of 19/64 inch diameter.

Installation Notes

Installation of this drill bit is performed by machinists, maintenance mechanics, HVAC technicians, and other trade professionals using standard drill equipment. Secure the straight shank fully into the chuck and tighten all jaws evenly before operation. Always wear appropriate eye protection and secure workpieces firmly before drilling. Use cutting fluid when drilling hard ferrous metals to extend bit life and maintain hole quality.
