Value Collection 01541572 Taper Shank Drill Bit

Product Description

The VALUE COLLECTION 01541572 is a taper shank drill bit designed for heavy-duty metal drilling in industrial and machine shop environments. It measures 1-57/64 inches (1.8906 inches decimal) in diameter and features a 4MT (Morse Taper No. 4) shank for direct mounting in compatible taper-spindle drill presses and lathes. The bit is manufactured from high-speed steel with an oxide finish for added lubricity and basic corrosion resistance. A standard 118-degree point angle makes it suitable for general-purpose drilling in a wide range of ferrous and non-ferrous materials. Web thinning reduces thrust and improves chip evacuation at larger diameters.

This drill bit is suited for general-purpose production drilling in machine shops, fabrication facilities, and maintenance operations. The 4MT taper shank seats directly into drill press quills, boring mills, and lathe tailstocks equipped with a No. 4 Morse Taper socket, eliminating the need for a separate chuck. It handles materials including mild steel, cast iron, and aluminum in both one-off and repetitive drilling applications.

Key Features

• 4MT Morse Taper shank for direct spindle mounting without a chuck
• High-speed steel construction for durability across general-purpose materials
• Oxide finish for improved lubricity and mild corrosion protection
• 118-degree standard point angle for versatile material compatibility
• Web-thinned point reduces drilling thrust at large diameters
• Right-hand spiral flute with regular helix for efficient chip removal

Compatibility

Designed for use in drill presses, boring mills, and lathe tailstocks fitted with a No. 4 Morse Taper (4MT) socket.

Installation Notes

Installation is performed by machinists or tooling technicians. Power down and lock out the machine before inserting or removing the taper shank. Clean both the bit taper and the spindle socket thoroughly before seating to ensure full contact and prevent slippage under load. Use a drift and knockout bar to remove the bit from the spindle — never strike the spindle housing directly.
