Value Collection 1146307 Taper Length Drill 0.6406 in Hss-e

Product Description

The VALUE COLLECTION 1146307 is a taper length drill bit designed for general-purpose drilling in metal, steel, and other ferrous and non-ferrous materials. Built from HSS-E Cobalt (M35 grade), the bit offers enhanced heat resistance and edge retention compared to standard high-speed steel. It measures 0.6406 inches (41/64 inch) in diameter with an overall length of 9 inches and a 118-degree split or conventional point angle. The bright, uncoated finish keeps the surface clean and allows for easy visual inspection of the cutting edge. This bit is sized and built for production and maintenance drilling environments where a longer reach is required.

This taper length drill bit is suited for machine shop, maintenance, and fabrication applications where standard-length bits do not provide enough reach. The 41/64 inch diameter and 5-7/8 inch flute length make it appropriate for through-hole drilling in thicker stock or for drilling in hard-to-reach locations. It is typically used with drill presses, milling machines, or CNC drilling equipment by machinists, toolroom technicians, and industrial maintenance professionals.

Key Features

• HSS-E Cobalt M35 construction provides improved heat resistance and longer tool life in hard materials
• 118-degree point angle suits general-purpose drilling across a wide range of metal types
• Taper length body at 9 inches overall length extends reach beyond standard jobber-length bits
• 5-7/8 inch flute length supports chip evacuation over deeper cuts
• Bright uncoated finish allows direct visual inspection of cutting edge condition
• 41/64 inch shank diameter matches the bit diameter for direct chuck mounting

Compatibility

Designed as a general-purpose taper length drill bit compatible with drill presses, milling machines, and CNC drilling equipment accepting a 41/64 inch straight shank.

Installation Notes

Install and secure the shank fully in the chuck before operation and verify runout before beginning the cut. Use appropriate cutting fluid or coolant when drilling hardened steels or stainless to extend tool life and reduce heat buildup. Ensure the workpiece is firmly clamped before drilling. Follow applicable shop safety standards and equipment manufacturer guidelines for spindle speed and feed rate selection.
