Value Collection 01541341 Taper Shank Drill Bit 4MT

Product Description

The VALUE COLLECTION 01541341 is a taper shank drill bit designed for general-purpose metal drilling in machine shop and production environments. It measures 1-17/32 inches (1.5313 inches decimal) in diameter and features a 4MT (Morse Taper 4) shank for secure seating in compatible drill presses, lathes, and milling machines. Constructed from high-speed steel with an oxide finish, it runs a 118-degree standard point angle with a web-thinned tip for improved centering and reduced thrust. The spiral flute geometry is regular right-hand cut, suited to a wide range of ferrous and non-ferrous materials.

This bit is intended for use in machine tool spindles accepting a 4 Morse Taper shank. With a flute length of 7-7/8 inches and an overall length of 13-3/4 inches, it handles deep-hole drilling applications where shorter jobber-length bits cannot reach. It is installed by machinists, tool-and-die workers, and maintenance technicians working on lathes, drill presses, and horizontal boring equipment. The general-purpose tool performance rating makes it appropriate for production drilling across a variety of workpiece materials at standard cutting speeds.

Key Features

• 1-17/32 inch diameter (1.5313 inches decimal) for large-bore drilling applications
• 4MT Morse Taper shank for positive, self-holding fit in compatible machine spindles
• 118-degree standard point angle with web-thinned tip for improved penetration and centering
• High-speed steel construction with oxide finish for heat and wear resistance
• 7-7/8 inch flute length enables deep-hole reach beyond jobber-length capability
• Right-hand spiral flute with regular helix for efficient chip evacuation

Compatibility

Designed to seat in machine tool spindles, drill press quills, and lathe tailstocks equipped with a No. 4 Morse Taper socket. Coolant-through drilling is not supported by this bit.

Installation Notes

Installation is performed by machinists or maintenance technicians. Power down and lock out the machine before inserting or removing the taper shank. Clean both the shank and the spindle socket of chips and oil before seating to ensure full taper contact. Use a drift and mallet to eject the bit through the spindle drift slot - do not pry or strike the flutes directly.
