Value Collection 01551639 Taper Shank Drill Bit 5MT Hss

Product Description

The VALUE COLLECTION 01551639 is a taper shank drill bit engineered for heavy-duty boring in metal, fabrication, and machining applications. Built from high-speed steel (HSS) with an oxide finish, this bit measures 1-63/64 inches (1.9844 inches decimal) in diameter and delivers consistent performance in general-purpose drilling operations. The 118-degree standard point angle provides reliable entry geometry across a wide range of ferrous and non-ferrous materials. Web-thinned construction reduces thrust requirements at the cutting tip. This bit is sized for use in large floor-standing drill presses, radial arm drills, and milling machines equipped with a No. 5 Morse taper spindle.

Intended for machine shops, metal fabricators, industrial maintenance crews, and tool-room applications, this drill bit handles large-diameter through-holes in steel plate, cast iron, and similar materials. The right-hand spiral flute with regular spiral geometry promotes chip evacuation during deep-hole drilling. At 17-3/8 inches overall length with a 10-3/8 inch flute length, it accommodates significant depth-of-cut requirements without tool changes. No coolant-through capability is present, so flood or mist cooling at the periphery is recommended for extended cuts in harder materials.

Key Features

• 1-63/64 inch (1.9844 inches) diameter for large-bore applications
• No. 5 Morse taper (5MT) shank for direct spindle mounting without a chuck
• High-speed steel construction with oxide finish for heat and wear resistance
• 118-degree standard point angle with web-thinned tip to reduce entry thrust
• 10-3/8 inch flute length supports deep-hole drilling in thick stock
• Right-hand, regular spiral flute for efficient chip clearing

Compatibility

Designed for use in drill presses, radial arm drills, and milling machines equipped with a No. 5 Morse taper (5MT) spindle socket. A 5MT sleeve or adapter may be required when mounting in larger-spindle machines.

Installation Notes

Installation and use should be performed by a qualified machinist or toolroom technician. Power down and lock out the machine spindle before seating or removing the taper shank. Clean both the shank taper and the spindle socket with a clean cloth before insertion to ensure full metal-to-metal contact and prevent fretting. Do not use this bit in a standard keyed chuck — the 5MT taper is designed for direct spindle mounting only.
