Value Collection 01531284 Taper Shank Drill Bit 3MT Hss

Product Description

The VALUE COLLECTION 01531284 is a taper shank drill bit engineered for general-purpose drilling in metal, wood, and similar materials. It carries a Morse Taper 3 (3MT) shank, making it compatible with taper-socket spindles found on drill presses, lathes, and milling machines. The cutting end features an 118-degree standard point with web thinning to reduce thrust and improve centering. Manufactured from high-speed steel (HSS) with an oxide finish, this bit delivers reliable performance in production and maintenance environments. At 1.4375 inches in diameter with a 6.75-inch flute length and 11.75-inch overall length, it handles deep-hole and large-diameter drilling tasks across a wide range of shop applications.

This taper shank drill bit is suited for machine shops, maintenance facilities, and industrial production settings where large-diameter holes are drilled regularly. The 3MT shank seats directly into compatible taper sockets without an additional chuck, reducing runout and improving rigidity. Right-hand spiral fluting clears chips efficiently during through-hole and blind-hole drilling. General-purpose HSS construction makes it appropriate for ferrous metals, non-ferrous metals, plastics, and wood. A licensed machinist or toolroom technician typically operates this type of tooling.

Key Features

• 1-7/16 inches (1.4375 inches) diameter for large-format hole cutting
• Morse Taper 3 (3MT) shank for direct socket mounting on compatible machines
• 118-degree standard point with web thinning to reduce entry thrust and improve accuracy
• High-speed steel construction with oxide finish for general-purpose durability
• 6.75-inch spiral flute length for efficient chip evacuation in deep cuts
• Right-hand cutting direction with regular spiral for standard machine spindles

Compatibility

Designed for use in drill presses, lathes, and milling machines equipped with a Morse Taper 3 (3MT) socket spindle.

Installation Notes

Installation is performed by a machinist or qualified toolroom technician. Power down and lock out the machine before seating or removing the taper shank. Clean both the shank and the socket bore thoroughly before insertion to ensure full taper contact and prevent runout. Never force a mismatched taper size into a socket, as this can damage both the spindle and the bit.
