Hertel C.402.0110 Jobber Drill 1.10mm 118 Deg Hss

Product Description

The HERTEL C.402.0110 is a high speed steel jobber-length drill bit designed for general-purpose drilling in metal, wood, and plastics. It features a 118-degree standard point angle for reliable center-starting on flat and curved surfaces. The oxide coating provides a light surface hardness and helps reduce friction during cutting. With an overall length of 44 millimeters and a 1.10 mm diameter, this bit fits standard drill chucks and is sized for small-diameter precision work. Machinists, tool-and-die technicians, and maintenance professionals keep sizes like this on hand for pilot holes, through-holes in thin stock, and production drilling tasks.

This drill bit is suited for light-duty production and maintenance drilling operations where small-diameter holes are required. The straight-cylindrical shank seats directly in standard keyless or keyed chucks without adapters. The spiral flute geometry clears chips efficiently in short-run drilling. Its general-purpose grade makes it appropriate for a broad range of base metals and non-ferrous materials in shop, field, and machine-tool environments.

Key Features

• 1.10 mm diameter with 0.0433 inch decimal equivalent for cross-reference
• 118-degree standard point angle for versatile, self-starting entry

• Right-hand cutting direction, compatible with standard drill presses and hand drills

Compatibility

Designed as a general-purpose jobber drill for use in standard drill chucks accepting straight-cylindrical shanks across drill presses, CNC machines, and handheld power tools within the 0.00 mm to 2.00 mm drill bit size range.

Installation Notes

Secure the shank fully in the chuck jaws before beginning any drilling operation. Always power down or unplug the drill press or deenergize the machine tool before changing bits. Use appropriate cutting fluid or coolant for extended runs in ferrous metals to preserve cutting edge life. Wear proper eye protection and follow applicable shop safety procedures when operating rotating cutting tools.
