Guhring 9085100041000 Screw Machine Drill Bit 4.10mm

Product Description

The GUHRING 9085100041000 is a solid carbide screw machine length drill bit engineered for high-performance drilling in demanding materials. It features a 4.10 mm diameter, a 140-degree facet point, and GUHRING's proprietary nano-A multi-layer coating, which reduces friction and extends tool life in abrasive applications. With an overall length of 66.00 mm and a 6.00 mm straight cylindrical shank, this bit is sized for use in CNC machining centers, screw machines, and precision drill presses. Right-hand cutting with a regular spiral flute and web-thinned point geometry allows for clean entry and efficient chip evacuation. This tool is designed for machinists and tooling professionals working in production environments.

This drill bit is suited for drilling stainless steel and high-temperature alloys where tool longevity and hole quality are critical. The coolant-through design supports internal coolant delivery, making it a strong fit for high-cycle production operations where heat management is essential. It conforms to DIN 6537 K standards and carries a 3xD flute-to-diameter ratio with a maximum drilling depth of 17.85 mm. Typical applications include aerospace component machining, medical device manufacturing, and precision stainless fabrication where tight tolerances are required.

Key Features

• Solid carbide construction with nano-A multi-layer coating for extended wear resistance in stainless steel and high-temp alloys
• 140-degree facet point with web-thinned geometry for reduced thrust and clean hole entry
• Coolant-through design supports internal coolant delivery for heat control in high-cycle applications
• Right-hand cut, regular spiral flute for efficient chip evacuation
• Conforms to DIN 6537 K standard; material grade K40 carbide
• Diameter tolerance m7 for consistent, repeatable fit in precision toolholders

Compatibility

Designed as a Series 8510 screw machine length drill bit 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. Drill bit size range covered by this series is 3.50 mm to 5.00 mm.

Installation Notes

Installation should be performed by a qualified machinist or tooling technician. Ensure the machine spindle and toolholder are fully powered down and at rest before inserting or removing the bit. Confirm the straight shank is fully seated and clamped to the torque specification required by your toolholder manufacturer. When using the coolant-through feature, verify coolant lines are connected and flow is confirmed before beginning the cut cycle.
