Hertel C.402.1160 Jobber Drill Bit 11.60 Mm Hss

Product Description

The HERTEL C.402.1160 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 starting without a center punch in most applications, and an oxide coating that reduces friction and helps extend tool life. The straight-cylindrical shank seats securely in standard three-jaw chucks and keyed drill chucks alike. With an overall length of 143 millimeters and a flute length of 106 millimeters, it fits the classic jobber proportions machinists and maintenance technicians rely on for through-hole and blind-hole work in production and repair environments.

This drill bit is suited for use in drill presses, CNC machining centers, and hand-held drill motors where a standard jobber-length bit is appropriate. The 11.60 mm diameter - equivalent to 0.4567 inches - places it in the 10.00 mm to 12.50 mm size range, making it a practical choice for clearance holes, pilot holes, and through-holes in general fabrication, maintenance, and light manufacturing. It is sold and packaged as a single unit, making it easy to stock as a direct replacement when a worn bit needs to be swapped out quickly.

Key Features

• 11.60 mm (0.4567 inch) diameter for precise hole sizing
• 118-degree standard point angle for general-purpose entry and self-centering performance
• High speed steel construction provides toughness across a broad range of workpiece materials
• Oxide coating reduces friction and helps resist heat buildup during cutting
• Right-hand spiral flute geometry evacuates chips efficiently from the cut zone
• Straight-cylindrical shank fits standard drill chucks without adapters

Compatibility

Designed as a general-purpose jobber drill bit compatible with standard three-jaw drill chucks and collet-style tool holders that accept straight-cylindrical shanks in the 10.00 mm to 12.50 mm drill size range.

Installation Notes

Installation is performed by machinists, toolroom technicians, and maintenance mechanics. Secure the shank fully in the chuck and verify runout before drilling. Wear appropriate eye protection and secure the workpiece before starting the spindle. Do not exceed the speed and feed recommendations for the workpiece material and machine type being used.
