Hertel C.402.0175 Jobber Drill 1.75mm Hss Oxide

Product Description

The HERTEL C.402.0175 is a high speed steel jobber-length drill bit ground to a standard 118-degree point angle with an oxide finish. Sized at 1.75 mm (0.0689 inches) in diameter, it delivers general-purpose drilling performance across a range of materials including mild steel, aluminum, wood, and plastics. The oxide coating provides light corrosion resistance and reduces friction during the cut. With an overall length of 51 mm and a flute length of 25 mm, this bit fits standard drill chucks and is suited for bench-drill, drill-press, and hand-drill applications. Machinists, maintenance techs, and fabrication professionals use it for precision small-diameter work where consistent geometry matters.

This jobber drill is designed for general-purpose drilling tasks in light manufacturing, maintenance, and fabrication environments. Its straight-cylindrical shank seats securely in keyed or keyless chucks without the need for special toolholders. The two-flute spiral design clears chips efficiently in both through-hole and blind-hole drilling operations. It is appropriate for use in ferrous and non-ferrous metals, thermoplastics, and composite materials at standard drilling speeds for the 1.75 mm diameter range.

Key Features

• 1.75 mm (0.0689 inches) diameter for precise small-bore work
• 118-degree standard point angle for general-purpose material entry
• High speed steel construction provides wear resistance across common shop materials
• Oxide coating reduces friction and light surface corrosion
• Two-flute spiral geometry promotes efficient chip evacuation
• Straight-cylindrical shank compatible with standard drill chucks

Compatibility

Designed as a general-purpose jobber drill for use in standard keyed and keyless drill chucks accepting straight-cylindrical shanks in the 1.75 mm diameter range.

Installation Notes

Install in a properly rated drill press or hand drill with the chuck tightened securely before operation. Ensure the workpiece is firmly clamped or secured to prevent movement during drilling. Apply appropriate cutting fluid for metal drilling to extend bit life and maintain dimensional accuracy. Inspect the cutting edges before each use and replace the bit if chipping or dulling is observed.
