Value Collection 01531052 Taper Shank Drill Bit 1-5/64 in

Product Description

The VALUE COLLECTION 01531052 is a taper shank drill bit engineered for heavy-duty drilling in metal, cast iron, and similar hard materials. The bit measures 1-5/64 inches (1.0781 inches decimal) in diameter with an overall length of 11.5 inches and a flute length of 6.875 inches. Constructed from high-speed steel (HSS) with an oxide finish for added lubricity and corrosion resistance, it features a 118-degree standard point angle and a web-thinned tip to reduce thrust and improve chip evacuation. This bit is designed for right-hand, clockwise cutting in general-purpose machining applications.

This drill bit is suited for use in drill presses, milling machines, and lathes equipped with a Morse taper spindle or sleeve. The No. 3 Morse taper (3MT) shank provides secure, self-holding engagement in compatible machine spindles. It handles general-purpose drilling operations in production shops, maintenance departments, and machine shops where large-diameter, accurate hole-making is required. The spiral flute geometry supports efficient chip removal during through-hole and blind-hole drilling in a range of workpiece materials.

Key Features

• 1-5/64 inch diameter (1.0781 inches decimal) for precise, large-diameter hole sizing
• No. 3 Morse taper (3MT) shank for self-holding fit in compatible machine spindles
• High-speed steel construction for durability across general-purpose metal drilling
• Oxide finish reduces friction and improves heat dissipation during cutting
• 118-degree standard point with web thinning to lower drilling thrust and improve chip flow
• Regular spiral, right-hand cutting flute geometry for consistent chip evacuation

Compatibility

Designed for use in machine spindles and drill press quills accepting a No. 3 Morse taper (3MT) shank, either directly or with a suitable Morse taper sleeve or adapter.

Installation Notes

Installation and removal should be performed by a qualified machinist or tool-and-die technician. Ensure the machine spindle and taper shank are clean and free of chips or burrs before seating the bit to ensure proper taper engagement. Use a drift key and drift slot to safely eject the bit from the spindle — never strike the bit or spindle directly with a hammer. Confirm the machine is fully de-energized and the spindle has stopped completely before changing tooling.
