Hertel C.402.0800 Jobber Drill Bit 8.00 Mm Hss

Product Description

The HERTEL C.402.0800 is a high speed steel jobber-length drill bit ground to an 8.00 mm diameter with a standard 118-degree split-point angle. It is oxide coated to reduce friction and extend tool life during general-purpose drilling operations. The straight-cylindrical shank seats securely in standard drill chucks, and the two-flute spiral geometry clears chips efficiently in a right-hand cutting direction. With an overall length of 114.00 mm and a flute length of 81.00 mm, this bit is sized for typical jobber-length reach in metal, wood, and plastic substrates. Machinists, maintenance technicians, and fabricators reach for this size regularly in production and repair settings.

This drill bit is suited for general-purpose applications across light manufacturing, maintenance, repair, and fabrication work. It performs in drill presses, CNC machining centers, and hand-held power drills where a standard jobber-length bit in the 8.00 mm range is required. The oxide finish makes it a practical choice for ferrous metals and similar materials where a non-coated bit would see accelerated wear. No coolant-through capability is present, so conventional surface or flood cooling methods apply for extended runs in harder materials.

Key Features

• 8.00 mm diameter with 0.3150 inch decimal equivalent for cross-reference
• 118-degree standard point angle for general-purpose entry and centering
• High speed steel construction with oxide coating to reduce friction and resist wear
• Two-flute spiral geometry promotes efficient chip evacuation in right-hand cutting direction
• Straight-cylindrical shank compatible with standard drill chucks and collets
• Jobber-length proportions at 114.00 mm OAL and 81.00 mm flute length

Compatibility

Designed as a general-purpose jobber drill bit for use in standard drill chucks and collets accepting an 8.00 mm straight-cylindrical shank, suitable for drill presses, lathes, and handheld power drill applications in the 8.00 mm to 9.00 mm size range class.

Installation Notes

Secure the straight shank fully in the chuck or collet before operation and verify concentricity to avoid premature edge wear. Machinists and maintenance technicians should select an appropriate cutting speed and feed rate for the workpiece material. Apply cutting fluid or coolant at the surface when drilling harder ferrous materials for extended tool life. Inspect the cutting edges before each use and replace the bit if chipping or dulling is observed.
