Guhring 9024580015900 Cobalt Jobber Drill Bit 1/16 in

Product Description

The GUHRING 9024580015900 is a cobalt jobber-length drill bit designed for high-performance drilling in demanding materials. Measuring 1/16 inch (0.0626 inch decimal) in diameter with a 130-degree cone-relief point, this bit is built for self-centering entry and clean hole starts. The FIREX coating reduces friction and extends tool life in abrasive and high-heat applications. The straight-cylindrical shank and regular spiral flute geometry maintain cutting efficiency at a 5xD flute-to-diameter ratio. Licensed HVAC, mechanical, and metalworking tradespeople will find this bit reliable for precision small-diameter work in hard alloys.

This bit is engineered for drilling titanium alloy and similar high-strength workpiece materials, designated under primary workpiece material code M and S. The Series 2458 design conforms to DIN 338 standards, making it appropriate for toolrooms, maintenance shops, and field service applications where consistent small-diameter hole quality is required. With a 43 mm overall length and a 20 mm flute length, it fits standard jobber-length drill chucks and is suitable for both bench drilling and handheld operations on metal fabrication and service work.

Key Features

• Cobalt construction for increased heat and wear resistance in hard materials
• FIREX coating reduces friction and extends cutting life in abrasive alloys
• 130-degree cone-relief point with web thinning for self-centering starts
• Right-hand, regular spiral flute for efficient chip evacuation
• DIN 338 standard compliance for consistent dimensional accuracy
• Straight-cylindrical shank with h8 diameter tolerance for secure chuck fit

Compatibility

Designed as a DIN 338 jobber-length drill bit for use in standard straight-shank drill chucks; primary workpiece material designation covers titanium alloy and similar M and S category high-strength metals.

Installation Notes

Installation and use should be performed by qualified machinists or tradespeople familiar with small-diameter drill bit handling. Secure the shank fully in a properly rated drill chuck before operation and confirm chuck runout is within tolerance to prevent bit deflection or breakage at this diameter. Power down and lock out all equipment before changing bits. Do not apply side load to small-diameter bits; use a drill press or stable fixture whenever possible to maintain alignment.
