Hertel C.402.0610 Jobber Drill Bit 6.10 Mm Hss

Product Description

The HERTEL C.402.0610 is a general-purpose jobber-length drill bit designed for precision hole drilling in a wide range of materials. Manufactured from high speed steel with an oxide coating, it measures 6.10 mm (0.2402 inches) in diameter with a standard 118-degree point angle. The overall length is 102 mm, and the flute length is 70 mm. The two-spiral flutes clear chips efficiently during drilling, and the right-hand cutting direction suits standard drill press and hand-drill operation. This bit is a reliable workhorse for machinists, maintenance technicians, pipefitters, and fabricators who need consistent performance in everyday drilling applications.

This jobber drill bit is suited for general-purpose drilling in metal, plastic, and similar materials in shop, field, or production environments. The straight cylindrical shank fits standard drill chucks across a broad range of drill presses, hand drills, and CNC machines. It falls within the 6.00 mm to 7.00 mm drill bit size range and the 0.2000 to 0.2500 decimal inch range, making it a common sizing choice for tapping prep, clearance holes, and through-hole work in light fabrication and maintenance tasks.

Key Features

• 6.10 mm (0.2402 inch) diameter with a standard 118-degree point angle for general-purpose drilling
• High speed steel construction with oxide coating for basic wear and heat resistance
• Two spiral flutes promote efficient chip evacuation during drilling
• Right-hand cutting direction compatible with standard drill chucks and machines
• Straight cylindrical shank fits most standard drill chucks without adapters
• Jobber-length design at 102 mm overall length for balanced reach and rigidity

Compatibility

Designed as a general-purpose replacement or stock drill bit for any application requiring a 6.10 mm straight-shank jobber drill in the 6.00 mm to 7.00 mm size range.

Installation Notes

This drill bit is installed and operated by machinists, maintenance technicians, and fabricators using standard drill chucks. Ensure the shank is fully seated and the chuck is tightened securely before operation. Use appropriate cutting fluid or coolant where required by material type, as this bit does not support coolant-through delivery. Inspect the cutting edges for wear before use and replace if chipping or dulling is observed to maintain hole quality and prevent workpiece damage.
