Hertel C.402.0250 Jobber Drill Bit 2.50 Mm Hss

Product Description

The HERTEL C.402.0250 is a high speed steel jobber-length drill bit designed for general-purpose drilling in metal, wood, and plastics. The bit features a 118-degree standard point angle, a spiral flute configuration, and an oxide finish that provides light corrosion resistance and reduces friction during cutting. At 2.50 mm in diameter (0.0984 inches decimal equivalent) with an overall length of 60 mm and a flute length of 35 mm, this bit suits precision drilling tasks where a compact, consistent jobber-length tool is required. It is a single-piece unit with a straight-cylindrical shank for use in standard drill chucks.

This drill bit is suited for shop, maintenance, and production environments where small-diameter hole making is routine. It fits into the 2.00 mm to 3.00 mm drill bit size range and is appropriate for light-to-medium duty applications across fabrication, assembly, and repair work. Right-hand cutting direction is standard for conventional drill press and hand drill operation. The general-purpose grade makes it a practical stock item for toolrooms, HVAC sheet metal work, plumbing rough-in, and electrical panel fabrication where small pilot holes or clearance holes are frequently needed.

Key Features

Compatibility

Designed as a general-purpose jobber drill bit compatible with any standard drill chuck accepting a straight-cylindrical shank in the 2.00 mm to 3.00 mm size range.

Installation Notes

Installation is performed by machinists, tool and die technicians, and trade professionals using a drill press, CNC machine, or hand drill with a standard 3-jaw chuck. Secure the workpiece before drilling to prevent movement. Use appropriate cutting fluid or lubrication when drilling ferrous metals to extend tool life. Inspect the cutting edges before use and replace the bit if chipping or excessive wear is present.
