Cleveland C72147 Jobber Drill Bit No. 47 Hss 118 Deg

Product Description

The CLEVELAND C72147 is a jobber-length drill bit sized to wire gauge No. 47, with a decimal diameter of 0.0785 inches. Made from high speed steel with a bright uncoated finish, this bit features a 118-degree standard point angle and a two-flute right-hand spiral configuration. The overall length is 2 inches, with a 1-inch flute length and a straight-cylindrical shank of 0.0785 inches in diameter. The web is thinned and tapered, which reduces thrust at entry and helps maintain point stability in small-diameter work. It is classified as a general purpose tool and conforms to ASME B94.11M and DIN 338 standards. Licensed trade professionals and production machinists are the primary users.

This drill bit is suited for general-purpose drilling in metal, plastic, and similar materials where a wire gauge No. 47 hole is required. The 4xD flute-to-diameter ratio supports chip evacuation in short, through-hole operations. Typical applications include tapping pre-drill work, instrument and electrical panel fabrication, and light fixture or enclosure assembly where small-diameter precision holes are needed. The right-hand cut and regular spiral are standard for most bench drill, hand drill, and CNC drilling operations in trade and production environments.

Key Features

• Wire gauge No. 47 diameter: 0.0785 inches decimal equivalent
• 118-degree standard point angle with web-thinned, tapered web for reduced entry thrust
• High speed steel construction with bright uncoated finish
• Right-hand cut, two-flute regular spiral for general-purpose use
• Straight-cylindrical shank at 0.0785 inches for standard chuck compatibility
• Conforms to ASME B94.11M and DIN 338 standards

Compatibility

Designed as a general-purpose jobber-length drill bit for use in standard three-jaw drill chucks accepting a 0.0785-inch straight-cylindrical shank. Suitable for bench drill presses, hand drills, and CNC drilling setups configured for small-diameter wire gauge bits.

Installation Notes

Installation and use should be performed by a qualified machinist or trade professional familiar with small-diameter drill bit handling. Secure the shank fully in the chuck before operation and verify chuck runout is within tolerance, as small-diameter bits are sensitive to misalignment. Power down and de-energize the drill press or machine spindle completely before changing bits. Do not exceed the recommended feed rate for the material being drilled, as small-diameter high speed steel bits are susceptible to breakage under excessive lateral load.
