Value Collection 1057540 Taper Length Drill 0.8438 in

Product Description

The VALUE COLLECTION 1057540 is a taper length twist drill bit designed for demanding metal removal applications. Built from HSS-E Cobalt M35-grade high-speed steel, it delivers elevated heat resistance and edge retention compared to standard HSS tooling. The bit measures 0.8438 inches (27/32 inch) in diameter with a 118-degree split-point angle, a flute length of 6.75 inches, and an overall length of 10.25 inches. It ships with a bright, uncoated finish. This drill is suited for machinists, toolmakers, and industrial maintenance technicians working in production or job-shop environments.

The 1057540 is intended for general-purpose drilling in ferrous and non-ferrous metals where a longer flute length is required to reach deeper hole depths or clear chips in extended drilling operations. Its taper length body provides added rigidity beyond jobber-length bits while maintaining compatibility with standard drill press chucks and milling machine spindles. The 27/32-inch shank diameter matches the drill body diameter for direct chuck mounting without a sleeve adapter.

Key Features

• HSS-E Cobalt M35 material grade for improved heat and wear resistance over standard HSS
• 118-degree drill point angle suitable for general-purpose metal drilling
• Taper length body at 10.25 inches overall with a 6.75-inch flute for extended reach
• 27/32-inch (0.8438-inch) diameter with matching shank for direct chuck mounting
• Bright, uncoated finish allows visual inspection of the cutting edge
• General-purpose grade rated for use across a wide range of workpiece materials

Compatibility

Designed as a general-purpose taper length drill bit compatible with standard drill press chucks, milling machine spindles, and magnetic drill units capable of accepting a 27/32-inch straight shank.

Installation Notes

Installation and operation should be performed by qualified machinists or maintenance technicians familiar with rotating cutting tool safety. Secure the shank firmly in the chuck and verify runout before drilling. Always use appropriate cutting fluid or coolant when drilling ferrous metals to extend tool life and manage heat. Ensure the workpiece is properly clamped before initiating the cut to prevent movement or tool breakage.
