Hertel C.E09.1230 Extra Length Drill Bit 0.4844 in

Product Description

The HERTEL C.E09.1230 is an extra length twist drill bit machined from high-speed steel with an oxide finish. It is designed for general-purpose drilling in metal, wood, and similar materials where added reach is required beyond standard jobber-length tooling. The bit measures 0.4844 inches in diameter with a 10 inch overall length and a 118-degree point angle, making it suitable for through-hole and deep-bore applications. Machinists, maintenance technicians, and tool-and-die professionals install this type of tooling in drill presses, lathes, and hand-held pneumatic or electric drills.

This extra length drill bit is used in manufacturing, fabrication, and maintenance applications where standard-length bits cannot reach the target bore depth. The extended flute length of 7.5 inches allows chip evacuation in deep-hole operations. It is appropriate for production shops, job sites, and maintenance facilities requiring reliable general-purpose drilling with extended reach capability.

Key Features

• 0.4844 inch diameter for precise sizing in general-purpose drilling applications
• 10 inch overall length provides extended reach beyond standard jobber-length bits
• 118-degree point angle suits a wide range of common materials
• 7.5 inch flute length supports chip clearance in deep-hole operations
• High-speed steel construction offers durability under typical drilling conditions
• Oxide finish provides mild corrosion resistance and reduced friction at the cutting surface

Compatibility

Designed as a general-purpose extra length drill bit compatible with standard drill chucks accepting a straight shank at 0.4844 inch diameter, suitable for drill presses, lathes, and compatible hand-held drilling equipment.

Installation Notes

Extra length drill bits are installed and removed by qualified machinists or maintenance technicians using a keyed or keyless chuck rated for the shank diameter. Ensure the drill press or machine spindle is fully powered down and the chuck is secured before beginning a drilling operation. Secure the workpiece firmly to prevent movement during cutting. Extra length tooling is more susceptible to deflection than standard-length bits, so use appropriate feed rates and support the workpiece close to the bore point when possible.
