Hertel C.402.0960 Jobber Drill Bit 9.60mm Hss

Product Description

The HERTEL C.402.0960 is a high speed steel jobber-length drill bit designed for general-purpose drilling in metal, wood, and plastic. It carries a 118-degree standard point angle for reliable center-starting and clean entry in a wide range of workpiece materials. The oxide coating reduces friction and provides light corrosion resistance during storage and use. At 130 millimeters overall length with a 95-millimeter flute length, it fits standard drill chucks and CNC drill spindles. Two right-hand spiral flutes evacuate chips efficiently and keep the cut cool. This bit is sized at 9.60 millimeters, equivalent to 0.3780 inches, and falls within the 9.00 to 10.00 millimeter drill size range.

This jobber drill is suited for production shops, maintenance and repair operations, and toolroom use. The straight cylindrical shank seats in keyed or keyless chucks without adapters. Its general-purpose grade makes it appropriate for light-to-medium drilling in mild steel, aluminum, brass, and thermoplastics. Machinists, tool and die makers, and maintenance technicians are the typical end users. It ships as a single unit and is sold individually.

Installation Notes

Installation and use should be performed by a qualified machinist or maintenance technician familiar with drill press, hand drill, or CNC spindle operation. Secure the shank fully in the chuck before powering the spindle, and confirm the workpiece is clamped or fixtured to prevent movement. Use appropriate cutting fluid or coolant for the workpiece material to extend tool life. Inspect the cutting edges for wear or chipping before each use and replace the bit if damage is detected.
