Value Collection 01541358 Taper Shank Drill Bit 4MT

Product Description

The VALUE COLLECTION 01541358 is a taper shank drill bit designed for heavy-duty boring in metal fabrication, machining, and industrial maintenance applications. Built from high-speed steel with an oxide finish, this bit measures 1-35/64 inches (1.5469 inches decimal) in diameter and delivers consistent, accurate holes in ferrous and non-ferrous materials. The 118-degree standard point geometry with web thinning reduces thrust and improves chip clearance at the start of the cut. A licensed machinist or tool and die technician is the typical end user for a bit in this size class.

This drill bit is suited for general-purpose drilling operations on machine tools equipped with a No. 4 Morse taper spindle, including floor-standing drill presses, lathes, and milling machines commonly found in production shops and maintenance facilities. The right-hand spiral flute design and 9-5/8-inch flute length accommodate deep-hole work in thick plate or structural stock. It is not intended for hand-held or portable drill use given the taper shank interface.

Key Features

• 1-35/64 inch (1.5469 inches decimal) cutting diameter for large-bore applications
• No. 4 Morse taper shank for direct spindle mounting without a chuck
• High-speed steel construction provides heat resistance during sustained drilling cycles
• Oxide finish reduces friction and provides light corrosion resistance
• 118-degree standard point angle with web thinning for reduced entry thrust
• Right-hand regular spiral flute for efficient chip evacuation

Compatibility

Designed to fit machine tools with a No. 4 Morse taper (4MT) spindle socket, including drill presses, lathes, and milling machines configured for taper shank tooling.

Installation Notes

Installation is performed by machinists or toolroom technicians. Power down and lock out the machine before inserting or removing the taper shank bit. Clean both the spindle taper and the bit shank with a clean cloth before seating to ensure full contact and prevent drift under load. Use a proper drift key and a soft-faced mallet to remove the bit from the spindle — never strike the spindle housing directly.
