Value Collection 1057935 Taper Length Drill 1.4375in 118deg

Product Description

The VALUE COLLECTION 1057935 is a taper length twist drill bit designed for heavy-duty drilling applications in metal, steel, and other hard materials. Ground from M35-grade HSS-E cobalt high-speed steel, this bit delivers improved heat resistance and edge retention compared to standard HSS tooling. It features a 118-degree split-point angle and a bright, uncoated finish. At 1.4375 inches (1-7/16 inches) in diameter with a 14.375-inch overall length, this is a large-diameter drill intended for production and maintenance machining environments where precision and tool life are critical.

This taper length drill bit is suited for general-purpose drilling in machine shops, fabrication facilities, and industrial maintenance settings. The extended taper length body provides added reach for through-holes in thick stock or deep workpieces. It is typically chucked in a floor-standing drill press, radial arm drill, or machining center equipped with a taper-shank or large-capacity chuck. A 9.625-inch flute length accommodates significant chip evacuation in deep-hole drilling operations.

Compatibility

Designed as a general-purpose taper length drill bit for use in drill presses, radial arm drills, and CNC machining centers with chucks or adapters rated for 1-7/16 inch shank diameters.

Installation Notes

This bit should be installed and operated by qualified machinists familiar with large-diameter drilling procedures. Ensure the machine spindle and chuck or adapter are rated to handle the 1-7/16 inch shank before securing. Always clamp workpieces firmly and use appropriate cutting fluid or coolant to manage heat buildup at this diameter. Power down and lock out the machine before changing or adjusting the bit.
