Hertel C.402.0650 Jobber Drill Bit 6.50 Mm Hss

Product Description

The HERTEL C.402.0650 is a high speed steel jobber-length drill bit designed for general-purpose drilling in metal, wood, and plastic. It features a 6.50 mm diameter (0.2559 inch decimal equivalent) with a standard 118-degree point angle that centers easily on most workpiece materials. The oxide coating reduces friction and provides moderate corrosion resistance. With an overall length of 105 mm and a spiral flute configuration, this bit suits benchtop drill presses and hand-held power drills alike. Machinists, maintenance technicians, and fabricators are the typical users of this type of tooling.

This jobber drill is suited for light- to medium-duty drilling applications in job shops, maintenance facilities, and general fabrication environments. The straight cylindrical shank accepts standard 3-jaw drill chucks without an adapter. The 73 mm flute length provides adequate chip evacuation for through-hole drilling in typical stock thicknesses. It is sold as a single unit, making it a straightforward replacement or line-item addition to an existing drill index.

Key Features

• 6.50 mm diameter with 0.2559 inch decimal equivalent for cross-reference against imperial drill charts
• 118-degree standard point angle for general-purpose use across common workpiece materials
• High speed steel construction with oxide coating for reduced friction during cutting
• Right-hand spiral flute geometry for efficient chip removal in standard drilling operations
• Straight cylindrical shank fits standard 3-jaw chucks without adapters
• 73 mm flute length supports through-hole drilling in typical stock thicknesses

Compatibility

Designed as a general-purpose jobber drill bit compatible with any drill press or hand-held power drill equipped with a standard 3-jaw chuck sized to accept a straight cylindrical shank in the 6.00 mm to 7.00 mm drill bit size range.

Installation Notes

This bit is installed and serviced by machinists, maintenance technicians, and fabricators following standard tooling procedures. Secure the straight cylindrical shank fully in the drill chuck and tighten with a chuck key before operation. Ensure the drill press or power tool is powered off and de-energized before changing tooling. Do not exceed the speed and feed recommendations appropriate for the workpiece material and bit diameter.
