Value Collection 1057746 Taper Shank Drill Bit 1 in 3MT

Product Description

The VALUE COLLECTION 1057746 is a cobalt taper shank drill bit designed for heavy-duty metal drilling in professional machining and fabrication environments. Built to a 1-inch diameter with a No. 3 Morse taper (3MT) shank, this bit seats directly into compatible taper-socket spindles and drill press quills without a separate chuck. The 118-degree standard point angle is suited for general-purpose work on steel, cast iron, and similar ferrous materials. Coolant-through capability allows cutting fluid to reach the tip during deep-hole operations, reducing heat buildup and extending tool life. The bright, uncoated finish allows easy visual inspection of the cutting edges.

This drill bit is suited for job-shop, production drilling, and maintenance-repair operations where a Morse taper shank is the preferred or required interface. The 3MT shank fits drill presses, lathes, and milling machines equipped with a No. 3 Morse taper socket. The right-hand spiral flute and N-thinned web reduce thrust requirements at the start of the cut, making it practical for drilling through plate, bar stock, and structural sections in ferrous metals. General-purpose tool performance makes it a dependable choice across a range of drilling applications.

Key Features

• 1-inch diameter cobalt construction for strength in ferrous metal drilling
• No. 3 Morse Taper (3MT) shank for direct spindle mounting without a chuck
• 118-degree standard point angle for general-purpose metal drilling
• Coolant-through design routes cutting fluid directly to the drill tip
• N-thinned web reduces axial thrust and improves chip clearance

Compatibility

Designed for use in drill presses, lathes, and milling machines equipped with a No. 3 Morse Taper (3MT) spindle socket.

Installation Notes

Installation is performed by machinists or toolroom technicians familiar with Morse taper tooling. Clean and inspect both the drill shank and the spindle socket before seating to ensure full taper contact. Power down and lock out the machine spindle before inserting or removing the bit. Use a drift key in the spindle slot to safely eject the taper shank — never strike the bit directly.
