Value Collection 1057511 Taper Shank Drill Bit 13/16 in

Product Description

The VALUE COLLECTION 1057511 is a cobalt taper shank drill bit designed for demanding metal drilling applications. Sized at 13/16 inches (0.8125 inches decimal), it features a 3MT (Morse Taper 3) shank for secure mounting in compatible taper-shank spindles, tailstocks, and drill press quills. The bit carries a 118-degree standard point angle with N-thinned web geometry for reduced thrust at entry. Right-hand spiral flutes in a regular helix pattern evacuate chips efficiently during through-hole and blind-hole operations. The bright/uncoated cobalt construction handles elevated cutting temperatures better than standard high-speed steel, making it a practical choice for stainless steel, cast iron, and other abrasion-prone materials.

This bit is suited for machine shop, maintenance, and fabrication environments where a rigid, high-torque drill setup is required. The 3MT taper shank seats directly into drill presses, lathes, and machining centers equipped with a Morse Taper 3 socket or sleeve. At 11.125 inches overall length with a 6.5-inch flute length, it handles moderate-depth holes without extension tooling. General-purpose tool performance rating makes it appropriate for a wide range of ferrous and non-ferrous workpieces in both production and job-shop settings.

Key Features

• Cobalt tool material provides superior heat resistance compared to standard HSS for hard and abrasive metals
• 3MT (Morse Taper 3) shank mounts directly in compatible taper-socket spindles without a chuck
• 118-degree standard point angle for general-purpose drilling across a broad range of materials
• N-thinned web reduces entry thrust and lowers risk of walking on flat workpiece surfaces
• Right-hand regular spiral flutes promote efficient chip evacuation in through-hole applications
• Bright/uncoated finish allows easy visual inspection of cutting edge condition during service
• Coolant-through capability supports high-speed or deep-hole operations when used with coolant-fed spindles

Compatibility

Designed for use in drill presses, lathes, machining centers, and similar machine tools equipped with a Morse Taper 3 (3MT) socket or appropriate reducing/extension sleeve.

Installation Notes

Installation is performed by machinists or tool-and-die professionals. Power down and lock out the machine spindle before seating or removing the taper shank. Clean both the taper shank and the receiving socket thoroughly before insertion to ensure full seating and prevent fretting. Use a drift and drift slot to safely eject the bit from the spindle rather than striking the bit body directly.
