Hertel C.402.0205 Jobber Drill Bit 2.05 Mm Hss

Product Description

The HERTEL C.402.0205 is a high speed steel jobber-length drill bit designed for general-purpose drilling in metal, wood, and plastic. It features a 118-degree standard point angle for reliable center-starting and clean entry, and an oxide coating that reduces friction and helps extend tool life in production drilling environments. The straight cylindrical shank is compatible with standard drill chucks and CNC toolholders. At 2.05 mm in diameter and 54 mm overall length, this drill is suited for precision small-diameter work in light manufacturing, maintenance, and fabrication applications. It is typically installed and used by machinists, tool-and-die technicians, and general maintenance professionals.

This drill bit is sized at 2.05 mm (0.0807 inches decimal equivalent), placing it within the 2.00 mm to 3.00 mm size range. It is well-suited for pilot holes, through-holes, and spotting operations on light-gauge ferrous and non-ferrous stock. The right-hand spiral flute geometry provides efficient chip evacuation during drilling. This bit ships individually and is available in multiples of 12, making it practical for shop restocking and toolcrib replenishment.

Key Features

• 118-degree standard point angle for self-centering entry and consistent hole location
• High speed steel construction provides hardness and wear resistance for general-purpose metal drilling
• Oxide coating reduces surface friction and helps resist heat buildup during operation
• Right-hand spiral flute design promotes active chip evacuation from the bore
• Straight cylindrical shank fits standard drill chucks and collet holders without modification
• No coolant-through requirement simplifies setup for bench drilling and handheld operations

Compatibility

Designed as a general-purpose jobber drill for use in standard drill presses, CNC machining centers, and handheld drill drivers equipped with a chuck compatible with a straight cylindrical shank in the 2.00 mm to 3.00 mm size range.

Installation Notes

A licensed machinist or qualified maintenance technician should secure this bit in a properly rated drill chuck before use. Ensure the chuck key is removed and the spindle is at a full stop before changing tooling. Follow facility safety protocols and applicable OSHA machine guarding requirements when operating drill presses or CNC equipment. Do not exceed the recommended feed and speed parameters for the workpiece material to avoid premature tool wear or breakage.
