Guhring 9065960040000 4mm Carbide Drill Bit 180 Deg

Product Description

The GUHRING 9065960040000 is a screw machine length drill bit engineered for high-performance drilling in demanding industrial applications. Built from solid carbide and coated with a proprietary multi-layer nano-FIREX finish, this bit delivers extended tool life and heat resistance in tough materials. The 4.00 mm diameter (0.1575 inch) bit features a 180-degree flat bottom point, making it well suited for flat-bottomed hole entry without a pilot. It measures 65.00 mm overall length with an 18.00 mm flute length and a 6.00 mm straight cylindrical shank. Coolant-through capability supports chip evacuation and heat management during continuous cutting cycles. Weighing 0.06 pounds, this is a precision tool for CNC and production drilling environments.

This drill bit is designed for right-hand, regular spiral flute cutting in steel, stainless steel, and cast iron. The screw machine length format provides a compact, rigid setup ideal for close-tolerance production drilling on CNC machining centers, drill presses, and screw machines. The 3xD flute-to-diameter ratio and maximum drilling depth of 12.00 mm suit through-hole and shallow blind-hole applications in high-volume manufacturing. The Series 6596 designation identifies it within the GUHRING performance drill lineup. Machinists and toolroom technicians in metalworking and precision manufacturing environments are the primary installers and users of this tool.

Key Features

• Solid carbide construction for rigidity and wear resistance in ferrous materials
• Proprietary multi-layer nano-FIREX coating for extended tool life and thermal protection
• 180-degree flat bottom point eliminates the need for a pilot hole on flat surfaces
• Coolant-through design supports chip evacuation and thermal control during deep or continuous cuts
• Straight cylindrical shank with 6.00 mm diameter fits standard toolholders and collet chucks
• Drill bit diameter tolerance N7 for consistent, close-tolerance hole sizing

Compatibility

Designed as an OEM-style cutting tool replacement for production drilling applications in steel, stainless steel, and cast iron workpieces using standard straight-shank toolholding systems.

Installation Notes

This tool should be installed by qualified machinists or toolroom technicians familiar with CNC toolholding and cutting parameter selection. Secure the shank fully in a collet chuck or hydraulic toolholder rated for the shank diameter before operation. Verify coolant-through connections are active before engaging the cut to protect tool life. Do not exceed the recommended maximum drilling depth of 12.00 mm per pass without confirmed chip evacuation.
