Hertel C.402.0125 Jobber Drill Bit 1.25 Mm Hss

Product Description

The HERTEL C.402.0125 is a general-purpose jobber-length drill bit designed for precision drilling in metal, plastic, and similar materials. Built from high speed steel with an oxide coating, it delivers solid wear resistance across routine drilling applications. The bit features a 118-degree standard point angle for reliable self-centering on flat and curved surfaces. At 1.25 mm in diameter (0.0492 inches decimal equivalent) and 48 mm overall length, this drill is sized for fine-detail work. It is installed and used by machinists, tool-and-die workers, maintenance technicians, and trade professionals requiring small-diameter hole production in light to moderate-duty operations.

This jobber drill fits standard drill chucks and is suited for bench drill presses, hand drills, and CNC drilling applications where a small-diameter straight-shank bit is required. The spiral flute geometry aids chip evacuation during through-hole drilling. Right-hand cutting direction is standard for conventional drill press and hand-tool use. The oxide finish provides a base level of corrosion resistance and reduces friction during cutting. This drill is well-suited for general fabrication, HVAC sheet metal work, electrical panel knockouts, and plumbing bracket fabrication.

Key Features

• 118-degree standard point angle for general-purpose drilling and reliable entry on flat stock
• High speed steel construction provides durability across a range of common materials
• Oxide coating reduces surface friction and offers light corrosion resistance
• Straight-cylindrical shank fits standard keyed and keyless drill chucks
• Two spiral flutes promote chip clearance and reduce heat buildup during drilling
• Right-hand cutting direction compatible with all standard drill equipment

Compatibility

Designed as a general-purpose jobber drill for use in any standard drill chuck accepting straight-cylindrical shanks in the 0.00 to 2.00 mm drill size range.

Installation Notes

This bit is installed by machinists and trade technicians in standard drill chucks on bench presses, hand drills, or CNC spindles. Secure the shank firmly in the chuck before operation and ensure the workpiece is properly clamped. Use appropriate cutting fluid for metal drilling to extend bit life and maintain hole quality. Inspect the cutting edges before each use and replace the bit if chipping or dulling is observed.
