Value Collection 01541523 Taper Shank Drill Bit 4MT

Product Description

The VALUE COLLECTION 01541523 is a taper shank drill bit designed for heavy-duty drilling operations requiring a secure, self-holding shank connection. Built from high-speed steel with an oxide finish, this bit measures 1.8125 inches (1-13/16 inches) in diameter and delivers reliable performance in general-purpose metal drilling applications. The 118-degree standard point geometry with web thinning reduces thrust and improves centering at the start of the cut. Machinists and tool-room professionals working with drill presses, lathes, and milling machines will find this bit suited to production and maintenance drilling where a Morse taper spindle is available.

This drill bit is intended for use in machine tool spindles and drill press quills that accept a No. 4 Morse taper (4MT) shank. It is appropriate for drilling through ferrous metals, mild steel, cast iron, and similar materials in both job-shop and production environments. The right-hand spiral flute with regular helix promotes efficient chip evacuation during through-hole and deep drilling passes. General-purpose tool performance makes it a practical stock item for maintenance shops and machine rooms handling a variety of bore sizes.

Key Features

• 1-13/16 inches (1.8125 inches) drill diameter for large-bore applications
• No. 4 Morse taper (4MT) shank for self-holding fit in compatible spindles
• High-speed steel construction provides heat resistance during general-purpose drilling
• 118-degree standard point angle with web thinning reduces entry thrust and improves bit centering
• Oxide finish offers mild corrosion resistance and reduces friction at the cutting edge
• Right-hand spiral flute with regular helix promotes consistent chip evacuation

Compatibility

Designed for use in machine tool spindles, drill press quills, and lathe tailstocks equipped with a No. 4 Morse taper socket. Coolant-through spindles are not required, as this bit does not support coolant-through delivery.

Installation Notes

Installation is performed by machinists or qualified tool-room personnel. Before mounting, power down and lock out the machine per OSHA lockout/tagout procedures. Clean the taper shank and the spindle socket thoroughly before seating to ensure full contact and prevent shank slippage under load. Use a proper drift and drift slot to remove the bit from the spindle — do not strike the bit or spindle directly to dislodge it.
