Guhring 9055230038600 Cobalt Jobber Drill Bit Wire 24

Product Description

The GUHRING 9055230038600 is a cobalt jobber length drill bit built to DIN 338 standards, sized to wire gauge 24 (0.1520 inches decimal). Manufactured from M35 cobalt high-speed steel, it delivers improved heat and wear resistance compared to standard HSS bits. The 118-degree four-facet split point geometry reduces walking on entry and lowers thrust requirements at the drill press or hand tool. With an overall length of 75 millimeters and a spiral flute length of 43 millimeters, this bit is suited to general-purpose drilling in a range of metalworking and fabrication applications. It is installed by machinists, tool and die technicians, and maintenance professionals requiring consistent, close-tolerance holes.

This drill bit is rated for use in aluminum, cast iron, steel, and non-ferrous materials, consistent with its K, M, N, and P workpiece material codes. The 2-flute right-hand spiral configuration clears chips efficiently in through-hole and blind-hole drilling operations. The straight-cylindrical shank measures 3.86 millimeters in diameter and 32 millimeters in length, making it compatible with standard drill chucks across benchtop and handheld power tools. A web-thinned, tapered web design reduces cutting resistance and extends tool life in production environments where cycle time and bit longevity matter.

Key Features

• M35 cobalt construction for elevated heat resistance during extended cutting cycles
• 118-degree four-facet split point reduces drill walk and lowers entry thrust
• DIN 338 standard jobber length: 75 millimeters overall, 43-millimeter flute length
• Right-hand cut, regular spiral, 2-flute design for efficient chip evacuation
• Web-thinned tapered web lowers cutting resistance in ferrous and non-ferrous materials
• Diameter tolerance held to +0.000 to -0.018 millimeters for consistent hole sizing

Compatibility

Designed as an OEM-style replacement jobber drill bit conforming to DIN 338 specifications, suitable for use in standard 3-jaw drill chucks accepting a 3.86-millimeter straight-cylindrical shank.

Installation Notes

Installation is performed by machinists or maintenance technicians using any drill press, CNC machine, or handheld power tool equipped with an appropriate chuck. Ensure the workpiece is firmly secured before drilling and that spindle speed is set to match the workpiece material and bit diameter per standard machining feeds-and-speeds references. No coolant-through capability is present on this bit; apply cutting fluid externally when drilling ferrous materials to extend tool life. Inspect the cutting edges before each use and replace the bit if chipping or excessive wear is observed.
