Guhring 9085100035000 Screw Machine Drill Bit 3.50mm

Product Description

The GUHRING 9085100035000 is a solid carbide screw machine length drill bit engineered for high-performance drilling in demanding materials. Built to DIN 6537 K standards and coated with GUHRING nano-A multi-layer coating, this bit delivers extended tool life and heat resistance in applications where standard HSS tooling fails. It features a 140-degree facet point for precise entry and reduced thrust, a web-thinned geometry for easier chip evacuation, and coolant-through capability for deep-hole thermal management. Machinists, tool-and-die shops, and precision fabricators rely on this series for consistent results in tight-tolerance work.

This drill bit is designed for cutting stainless steel and high-temperature alloys, where coating performance and carbide substrate quality directly impact cycle times and tool life. The screw machine length format provides rigidity in CNC machining centers, drill presses, and gang drilling setups where stub-length tooling is preferred over jobber-length alternatives. The straight cylindrical shank accommodates standard drill chucks and collet systems sized for a 6.00 mm shank diameter.

Key Features

• Solid carbide construction, grade K40, for hardness and wear resistance in abrasive and high-temp materials
• nano-A multi-layer proprietary coating reduces friction and extends tool life in stainless steel and high-temp alloys
• 140-degree facet point minimizes walking and reduces entry thrust on hard materials
• Web-thinned geometry promotes chip flow and lowers cutting forces
• Coolant-through design supports through-tool coolant delivery for deep drilling and heat control
• DIN 6537 K standard geometry ensures dimensional consistency and interchangeability

Compatibility

Designed for use in CNC machining centers and drill presses accepting a 6.00 mm straight cylindrical shank. Primary workpiece materials are stainless steel and high-temperature alloys. Part of GUHRING Series 8510.

Installation Notes

Installation and tool changes should be performed by qualified machinists with the machine powered off and in a locked-out state per applicable machine safety procedures. Verify collet or chuck bore matches the 6.00 mm shank diameter before seating the tool. When using coolant-through capability, confirm the spindle coolant system is properly pressurized and that coolant lines are clear before initiating a cut. Inspect the cutting edge and coating condition before each use and replace the bit if chipping or coating breakdown is observed.
