Guhring 9007680170000 Straight-flute Drill Bit 17mm

Product Description

The GUHRING 9007680170000 is a straight-flute, solid carbide drill bit engineered for high-performance drilling in aluminum, aluminum alloy, and cast iron. Built from submicron carbide with a bright/uncoated finish, this bit features a 120-degree standard point and web-thinned geometry that reduces thrust and promotes clean entry. With coolant-through capability via a round coolant-hole, it is suited for CNC machining centers and production environments where chip evacuation and heat management are critical. Machinists and tooling specialists working in metal fabrication and precision manufacturing will find this bit appropriate for close-tolerance hole-making applications.

This bit is designed for right-hand cutting and carries a DIN 6535HA shank specification, making it compatible with standard collet and tool-holder systems used in CNC drilling and boring operations. The 4xD flute-by-diameter ratio supports drilling to moderate depth with consistent chip clearance. It is well suited for production runs on aluminum and cast iron components where surface finish and dimensional accuracy are required.

Key Features

• Straight-flute geometry for controlled chip flow in aluminum and cast iron
• 120-degree standard point angle for accurate hole entry and reduced walking
• Web-thinned tip reduces axial cutting force and improves penetration
• Coolant-through design with round coolant holes for internal coolant delivery
• Submicron carbide substrate for extended tool life in high-performance applications
• DIN 6535HA shank for compatibility with standard CNC collet systems

Compatibility

Designed for use with standard DIN 6535HA-compliant collet chucks and tool holders on CNC machining centers. Primary workpiece materials include aluminum, aluminum alloy, and cast iron.

Installation Notes

Installation and tool changes should be performed by qualified machinists with the machine in a powered-off, locked-out state per OSHA lockout/tagout procedures. Ensure the shank is fully seated and torqued in the collet or tool holder per the tool-holder manufacturer specifications before operation. Verify coolant-through lines are clear and delivering adequate flow before drilling. Do not exceed the recommended cutting parameters for the workpiece material.
