Guhring 9055100060000 Carbide Screw Machine Drill Bit

Product Description

The GUHRING 9055100060000 is a solid carbide screw machine length drill bit designed for high-performance drilling in ferrous materials. Built to DIN 6537 K standards, this right-hand cut bit features a 140-degree split point (SU point type) with web thinning for reduced thrust and improved centering. The 6.00 mm (0.2362 inch) diameter matches the straight-cylindrical shank diameter, making it compatible with standard drill chucks and collet holders. Coolant-through capability supports higher feed rates and extended tool life in demanding production environments. Machinists, tool and die technicians, and CNC operators working with cast iron and steel are the primary users of this bit.

This drill bit is suited for screw machine work, CNC machining centers, and production drilling applications where short, rigid tooling is required. The 3xD flute-to-diameter ratio and screw machine length geometry keep the tool stiff in close-clearance setups. Primary target materials are cast iron and steel. The Series 5510 designation places this bit in a high-performance carbide drill family built for demanding metalworking environments where consistency and tight diameter tolerance are critical.

Key Features

• Solid submicron carbide construction for hardness and wear resistance in ferrous materials
• 140-degree SU split point with web thinning reduces entry thrust and improves hole location accuracy
• Coolant-through design channels cutting fluid directly to the cutting edge for heat management and chip evacuation
• Straight-cylindrical shank at 6.00 mm for direct chuck or collet mounting
• Diameter tolerance of +0.004 to +0.016 mm for consistent, repeatable hole sizing
• Conforms to DIN 6537 K specification for screw machine length carbide drills

Compatibility

Designed as a high-performance replacement for standard screw machine length carbide drill bits in the 0.2000 to 0.2500 inch (5.00 to 6.50 mm) diameter range, conforming to DIN 6537 K. Suitable for use in any holder accepting a 6.00 mm straight-cylindrical shank.

Installation Notes

Installation and operation should be performed by qualified machinists or CNC technicians familiar with carbide tooling. Ensure the spindle and workpiece are secure before beginning drilling operations. Carbide is brittle and susceptible to chipping from interrupted cuts or excessive runout — verify holder and collet concentricity before use. When using coolant-through capability, confirm that the machine spindle and toolholder support internal coolant delivery at the required pressure.
