Value Collection 01541317 Taper Shank Drill Bit 4MT Hss

Product Description

The VALUE COLLECTION 01541317 is a taper shank drill bit designed for heavy-duty drilling in metal, steel, and similar materials. Built from high-speed steel with an oxide finish, this bit delivers reliable performance in general-purpose machining and fabrication applications. It features a 1-31/64 inch (1.4844 inch decimal) diameter, a 118-degree standard point angle, and a right-hand spiral flute. The web-thinned tip reduces thrust and improves starting accuracy. At 15 inches overall length with a 9-3/8 inch flute length, this bit is suited for deep-hole operations on drill presses and milling machines. Licensed machinists and tool-and-die technicians are the primary installers.

This taper shank drill bit is used in industrial and job-shop environments where large-diameter holes are required in ferrous and non-ferrous metals. The 4MT (Morse Taper 4) shank seats directly into compatible spindles on drill presses, lathes, and boring mills without a chuck, providing a rigid, concentric connection. It is a general-purpose bit appropriate for production drilling and maintenance repair operations where standard tolerances are acceptable. The regular spiral flute promotes efficient chip evacuation during through-hole and deep drilling cycles.

Key Features

• 1-31/64 inch diameter with 4MT taper shank for direct spindle mounting
• 118-degree standard point angle with web-thinned tip for reduced entry thrust
• High-speed steel construction for general-purpose metal drilling
• Oxide finish provides mild corrosion resistance and reduces friction
• Right-hand, regular spiral flute design promotes chip clearance
• No coolant-through design — suitable for conventional flood or dry drilling setups

Compatibility

Designed for use in any machine spindle or sleeve accepting a 4MT (Morse Taper 4) taper shank, including standard drill presses, lathes, and milling machines configured for that taper size.

Installation Notes

Installation is performed by machinists or qualified tool operators. Power down and de-energize the machine spindle completely before seating or removing the taper shank. Clean the spindle socket and taper shank with a clean cloth to remove chips and oil before insertion to ensure full contact and prevent slippage. Use a proper drift and mallet to eject the bit from the spindle socket — never force removal in a way that could damage the taper seat.
