Cle-line C74004 Jobber Drill Bit 2.50 Mm Hss

Product Description

The CLE-LINE C74004 is a high-speed steel (HSS) jobber-length drill bit designed for precision drilling in steel, cast iron, and similar ferrous materials. It measures 2.50 mm in diameter (0.1000 inch) with an overall length of 2.2400 inches and a flute length of 1.1800 inches. The 135-degree split point reduces walking at startup and lowers the thrust force needed to penetrate hard materials. A black oxide and gold coating provides lubricity and basic corrosion resistance. This bit is a standard tool for machinists, pipefitters, and maintenance techs working in production or field environments.

The C74004 is sized for general-purpose jobber drilling in the 2.00 mm to 3.00 mm range. Its straight cylindrical shank fits standard drill chucks found on bench drill presses, hand drills, and CNC drilling spindles. The regular spiral flute geometry and right-hand cutting direction suit common rotary drilling setups. Typical applications include pilot-hole drilling, through-hole work, and production drilling in steel and cast iron workpieces where a light-duty, small-diameter bit is required.

Key Features

• 135-degree split point reduces drill walk and lowers entry thrust on hard metals
• High-speed steel construction rated for heavy-duty use per DIN specification
• Black oxide and gold coating adds surface lubricity and basic corrosion resistance
• Regular spiral flute promotes consistent chip evacuation during drilling
• Straight cylindrical shank compatible with standard drill chucks
• Tapered web configuration and 2-flute design maintain rigidity at small diameters

Compatibility

Designed as a standard jobber-length drill bit for use in hand drills, drill presses, and CNC drilling equipment equipped with chucks accepting a 0.1000-inch straight shank. Suitable for drilling steel and cast iron workpieces.

Installation Notes

Installation and use of this bit should be performed by a qualified machinist or maintenance technician familiar with rotary cutting tools. Secure the shank fully in the chuck before operation and verify the chuck key is removed before starting the spindle. Use appropriate cutting fluid or coolant for ferrous materials to extend tool life. Always wear eye protection and follow applicable shop safety standards when operating drilling equipment.
