Cleveland C72130 No 30 Hss Jobber Length Drill Bit

Product Description

The CLEVELAND C72130 is a jobber-length drill bit sized to wire gauge No. 30, with a decimal diameter of 0.1285 inches. Built from high speed steel with a bright uncoated finish, it features a 118-degree standard point angle and a web-thinned, tapered web construction that reduces thrust and improves chip clearance at entry. The spiral flute design runs in a right-hand cutting direction with a regular spiral type. At 2.75 inches overall length with a 1.625-inch flute length, this bit fits standard drill chucks via its straight-cylindrical shank. It is a general-purpose tool installed by machinists, maintenance technicians, plumbers, and electricians in production and field applications alike.

The C72130 is suited for general-purpose drilling in light metals, plastics, and similar materials where a wire-gauge No. 30 hole diameter is required. The jobber-length format provides a practical balance of reach and rigidity for bench drill presses, hand drills, and CNC drilling operations. Its 0.1285-inch shank diameter matches the bit diameter, making it compatible with standard collets and drill chucks sized for small-diameter bits. This series is commonly used in HVAC, electrical, and plumbing trades for pilot holes, clearance holes, and sheet metal work.

• Right-hand spiral flute in regular spiral type for efficient chip evacuation
• Meets ASME B94.11M and DIN 338 standards; ANSI specification designation

Compatibility

Designed as a general-purpose jobber-length drill bit for use in any standard drill chuck or collet accepting a 0.1285-inch straight-cylindrical shank. Part of the CLEVELAND Series 2002G line of wire-gauge drill bits.

Installation Notes

Install in a drill press, hand drill, or CNC spindle with a chuck rated for small-diameter bits. Secure the shank fully in the chuck and verify concentricity before drilling to prevent bit deflection at this diameter. No coolant-through capability is present on this bit; apply cutting fluid externally when drilling metals to extend tool life. Follow applicable shop safety practices and wear appropriate eye protection during operation.
