Value Collection 01541309 Taper Shank Drill Bit 4MT Hss

Product Description

The VALUE COLLECTION 01541309 is a taper shank drill bit designed for drilling large-diameter holes in metal, wood, and other materials in industrial and trade shop environments. It measures 1-15/32 inches (1.4688 inches decimal) in diameter with a 4MT Morse taper shank, an overall length of 13.5 inches, and a flute length of 7.625 inches. The bit is manufactured from high-speed steel with an oxide finish that provides surface hardness and basic corrosion resistance. A 118-degree standard point angle and right-hand spiral flute geometry make this a reliable general-purpose choice for production drilling operations.

This drill bit is suited for use in drill presses, milling machines, and lathes equipped with a No. 4 Morse taper spindle or sleeve adapter. It is appropriate for general-purpose metal fabrication, maintenance shops, and machine shops where large-diameter drilling in ferrous and non-ferrous materials is routine. The web-thinned point reduces thrust force at the cutting edge and helps initiate the hole without excessive pressure. Right-hand cutting direction is standard for conventional clockwise-rotating spindles.

Key Features

• 1-15/32 inch (1.4688 inch) diameter for large-bore drilling applications
• No. 4 Morse taper shank fits matching spindle sockets and sleeve adapters
• High-speed steel construction handles heat generated during metal drilling
• Oxide finish provides basic surface protection and reduces friction
• 118-degree standard point angle for general-purpose material entry
• Web-thinned geometry reduces cutting thrust and eases hole initiation
• Right-hand spiral flute with regular helix evacuates chips efficiently

Compatibility

Designed for use in drill press spindles, lathes, and milling machine quills with a No. 4 Morse taper socket; a sleeve or reducing adapter is required when the machine taper differs from 4MT.

Installation Notes

Installation and use should be performed by a qualified machinist or tooling technician familiar with taper-shank tooling. Ensure the machine spindle is fully stopped and locked out before seating or removing the taper shank. Clean both the shank and the spindle socket to remove chips, oil, and debris before insertion to prevent fretting and misalignment. Coolant-through is not supported on this bit, so adequate surface or flood coolant should be applied at the cutting zone when drilling ferrous metals to manage heat buildup.
