Hertel C.402.0105 Jobber Drill Bit 1.05 Mm Hss

Product Description

The HERTEL C.402.0105 is a high speed steel jobber-length drill bit designed for general-purpose drilling in metal, wood, and plastic. The bit measures 1.05 mm in diameter (0.0413 inches) with a standard 118-degree split point and an overall length of 41 mm (approximately 1.61 inches). An oxide coating helps reduce friction and resist heat buildup during drilling. The straight-cylindrical shank seats securely in standard drill chucks. With two spiral flutes and right-hand cutting direction, this bit clears chips efficiently in a wide range of production and maintenance drilling applications.

This drill bit is suited for light-duty production drilling, toolroom work, and maintenance operations where small-diameter precision holes are required. The 1.05 mm diameter falls within the 0.00 mm to 2.00 mm size range, making it appropriate for fine metalworking tasks such as pilot holes, circuit board work, and instrument assembly. It is typically used by machinists, maintenance technicians, and fabricators working with hand drills, drill presses, or CNC equipment.

Key Features

• 1.05 mm diameter (0.0413 inches) for fine, precise drilling
• 118-degree standard point angle for general-purpose use across multiple materials
• High speed steel construction provides durability and heat resistance
• Oxide coating reduces friction and extends tool life
• Two spiral flutes with right-hand cutting for efficient chip evacuation
• Straight-cylindrical shank fits standard drill chucks without adapters

Compatibility

Designed as a general-purpose jobber drill bit compatible with standard drill chucks and collets accepting straight-cylindrical shanks in the 0.00 mm to 2.00 mm drill size range.

Installation Notes

Installation and use should be performed by machinists or qualified technicians familiar with rotary cutting tools. Ensure the drill chuck is fully tightened and the workpiece is securely clamped before operation. Always wear appropriate eye protection when drilling. Do not exceed the recommended speed range for the material being drilled, and allow adequate chip clearance to prevent bit breakage at this small diameter.
