Value Collection 1057448 Taper Length Drill Bit Hss-e

Product Description

The VALUE COLLECTION 1057448 is a taper length twist drill bit designed for professional metalworking and machining operations. Built from M35-grade HSS-E cobalt steel, it delivers the elevated heat resistance and edge retention required when drilling through tough ferrous metals, stainless steel, and high-alloy materials. The bit measures 0.7656 inches (49/64 inch) in diameter with a 118-degree point angle, a flute length of 6.5 inches, and an overall length of 9.875 inches. The bright, uncoated finish is standard for general-purpose cobalt tooling and allows easy visual inspection of the cutting edge. Machinists and tool-and-die professionals are the primary users of this diameter and length class.

This taper length drill bit is suited for production drilling environments where a longer reach is needed beyond what a jobber-length bit provides. The extended flute length supports deeper hole applications in mill and lathe setups, CNC machining centers, and manual drill press work. The 49/64-inch shank diameter matches the bit diameter, making it compatible with standard drill chucks and collet systems that accept this size. General-purpose grade designation makes it appropriate for a wide range of shop floor applications including fixture work, mold and die, and structural metal fabrication.

Key Features

• M35-grade HSS-E cobalt construction for improved heat and wear resistance over standard HSS
• 118-degree point angle for general-purpose drilling in a broad range of metals
• 0.7656 inch (49/64 inch) diameter with matching shank for balanced chuck grip
• 6.5-inch flute length provides extended reach for deeper hole requirements
• Bright, uncoated finish for easy edge inspection and standard regrinding compatibility
• 9.875-inch overall length suits taper length drilling applications where jobber bits fall short

Compatibility

Designed as a general-purpose taper length drill bit compatible with standard drill chucks, Jacobs-style chucks, and collet systems sized for a 49/64-inch shank, used in drill presses, milling machines, lathes, and CNC machining centers.

Installation Notes

Installation and use of this drill bit should be performed by qualified machinists or tooling professionals familiar with rotating tool safety. Secure the shank fully in the chuck or collet before operation and verify runout before beginning a cut. Always use appropriate cutting fluid or coolant when drilling hard alloys to preserve edge life. Follow machine manufacturer RPM recommendations for the workpiece material and bit diameter.
