Hertel C.4C0.0476 Taper Shank Drill Bit 3/16 in 1MT

Product Description

The HERTEL C.4C0.0476 is a taper shank twist drill bit designed for precision drilling in metal, steel, and similar materials. It carries a 3/16 inch (0.1875 inch) cutting diameter and mounts via a No. 1 Morse Taper (1MT) shank, making it compatible with drill presses, lathes, and milling machines equipped with a matching MT1 spindle or sleeve. The 118-degree point angle is a standard general-purpose geometry suited for a wide range of ferrous and non-ferrous workpiece materials. With a flute length of 2.5 inches and an overall length of 5.75 inches, this bit provides sufficient reach for deep-hole applications at this diameter. Installation and use require a licensed or experienced machinist or tooling professional.

This drill bit is well suited for production shops, maintenance and repair operations, and toolroom environments where taper shank tooling is standard equipment. The 1MT shank fits directly into compatible spindle bores without additional chucking hardware, which reduces runout and improves concentricity compared to straight-shank tooling held in a chuck. It is appropriate for manual drill presses, CNC-capable lathes with MT1 tailstock bores, and similar machine setups requiring small-diameter drilling at moderate depths.

Key Features

• 3/16 inch (0.1875 inch) cutting diameter for small-bore precision drilling
• No. 1 Morse Taper (1MT) shank for direct spindle mounting without a chuck
• 118-degree standard point angle suitable for ferrous and non-ferrous materials
• 2.5 inch flute length supports deeper hole applications at this diameter
• 5.75 inch overall length for reach in drill press and lathe tailstock setups

Compatibility

Designed for use in machine spindles, lathe tailstocks, and drill press quills fitted with a No. 1 Morse Taper bore. A 1MT-to-larger-taper sleeve adapter may be required when used in spindles with a larger native taper designation.

Installation Notes

Installation is performed by a qualified machinist or tooling technician. Power down and lock out the machine before seating or removing the taper shank. Ensure the taper bore and shank are clean and free of chips or oil film before insertion to achieve proper seating and prevent slippage under load. A drift key and drift slot are the standard means of taper shank removal — never use a hammer directly on the shank body.
