Value Collection 1057156 Taper Length Drill 0.5313 in

Product Description

The VALUE COLLECTION 1057156 is a taper length drill bit designed for general-purpose drilling in metal, steel, and other ferrous materials. Built from HSS-E Cobalt (M35 grade), it delivers improved heat resistance and edge retention compared to standard high-speed steel. The 118-degree split-point geometry provides accurate starting without a center punch and reduces walking on flat surfaces. At 0.5313 inches (17/32 inch) in diameter with an overall length of 8 inches and a flute length of 5.25 inches, this bit handles deeper hole applications where a jobber-length drill cannot reach. Machinists, tool-and-die techs, and maintenance professionals are the primary users.

This taper length drill is suited for production and maintenance machining environments where extended reach is required. The bright, uncoated finish makes it a straightforward choice for general-purpose work in cast iron, mild steel, alloy steel, and similar materials. The taper length body provides added rigidity over longer flute designs while still accessing deeper workpiece sections. It is sold individually and fits standard drill chucks and machine spindles accepting 17/32-inch round shanks.

Key Features

• HSS-E Cobalt M35 construction for improved heat and wear resistance over standard HSS
• 118-degree point angle suits general-purpose drilling in ferrous and non-ferrous metals
• Taper length body provides extended reach beyond standard jobber-length bits
• Bright, uncoated finish is ready to use out of the box with no coating to chip or peel
• 17/32-inch (0.5313 inch) diameter with 5.25-inch flute length and 8-inch overall length

Compatibility

Designed as a general-purpose taper length drill bit for use in manual drill presses, CNC machining centers, and turret mills equipped with a chuck or collet accepting a 17/32-inch round shank.

Installation Notes

This bit is installed by machinists and maintenance technicians in standard drill chucks or collets. Ensure the machine spindle is fully stopped and the chuck is secure before beginning a drilling operation. Use appropriate cutting fluid for the workpiece material to extend tool life and maintain hole quality. Inspect the cutting edges before each use and re-sharpen or replace the bit if chipping or wear is detected.
