Value Collection 01663285 Taper Shank Drill Bit 7/16 in 1MT

Product Description

The VALUE COLLECTION 01663285 is a taper shank drill bit designed for general-purpose metal drilling in machine shop and industrial environments. It measures 7/16 inches in diameter and features a No. 1 Morse taper (1MT) shank for positive engagement in taper-socket spindles on drill presses, lathes, and milling machines. The 118-degree standard point angle suits a wide range of common metals and is complemented by a web-thinned tip to reduce thrust and improve penetration. High-speed steel (HSS) construction with an oxide finish provides baseline heat and wear resistance for everyday production drilling tasks. A licensed machinist or tool-and-die technician is the typical end user.

This drill bit fits applications where a Morse taper drive is required rather than a straight-shank chuck. Common install scenarios include drilling through mild steel, cast iron, aluminum, and similar materials on floor-standing drill presses or turret lathes equipped with a No. 1 Morse taper socket. The right-hand spiral flute and regular spiral type make it a direct fit for standard right-hand rotation spindles. With a 10-inch flute length and 15-inch overall length, it handles deep-hole work that shorter jobber-length bits cannot reach.

Key Features

• 7/16-inch (0.4375 inches) diameter for precise hole sizing
• No. 1 Morse taper shank seats securely in 1MT spindle sockets without a chuck
• 118-degree standard point angle for general-purpose drilling in common metals
• Web-thinned tip reduces drilling thrust and starting resistance
• 10-inch flute length supports deep-hole drilling applications
• Oxide finish on high-speed steel body for basic thermal and corrosion resistance

Compatibility

Designed for use in drill presses, lathes, and milling machines equipped with a No. 1 Morse taper (1MT) spindle socket; right-hand rotation spindles only.

Installation Notes

Installation is performed by machinists or qualified tool operators. Power down and lock out the machine spindle before inserting or removing the taper shank. Seat the taper fully by hand and verify positive engagement before applying power; a loose taper shank can spin and damage the socket. Use a drift key and a soft-faced mallet to eject the bit safely — never hammer directly on the flute or shank body.
