Guhring 9085100046500 Solid Carbide Drill Bit 0.1831 in

Product Description

The GUHRING 9085100046500 is a solid carbide screw machine length drill bit engineered for high-performance drilling in demanding applications. Built to DIN 6537 K standards, this bit features a 140-degree point angle, a web-thinned VA point type, and coolant-through capability, making it well-suited for precision work in difficult materials. The 0.1831-inch (4.65 mm) diameter and compact screw machine length body provide rigidity and accuracy in short-hole drilling operations. Licensed tradespeople working in aerospace, machining, and metalworking environments rely on bits in this class for consistent, repeatable results.

This drill bit is designed for use in CNC machining centers, drill presses, and other equipment capable of delivering coolant through the spindle. Its primary target workpiece material is titanium alloy, though the solid carbide construction and high-performance grade make it suitable for other hard and abrasive materials in similar hardness ranges. The straight-cylindrical shank with a 6.00 mm shank diameter seats securely in standard collet and chuck systems. It is a Series 8510 tool carrying a K40 material grade carbide substrate.

Key Features

• Solid carbide construction with K40 material grade for hardness and wear resistance
• 140-degree point angle with VA point type and web thinning for clean entry in hard materials
• Coolant-through design supports internal coolant delivery to extend tool life and improve chip evacuation
• 2-flute regular spiral configuration with a 3xD flute-to-diameter ratio for efficient chip removal
• Straight-cylindrical shank at 6.00 mm for compatibility with standard collet systems
• Manufactured to DIN 6537 K specification with m7 diameter tolerance for precision fitment

Compatibility

Designed as a Series 8510 screw machine length drill bit for use in machining operations targeting titanium alloy and similarly hard primary workpiece materials, compatible with coolant-through spindle setups using standard straight-cylindrical collet or chuck systems.

Installation Notes

Installation and use of this drill bit should be performed by qualified machinists or tooling technicians familiar with carbide tooling handling procedures. Ensure the machine spindle is fully stopped and locked out before installing or removing the bit from the collet or chuck. Confirm that internal coolant pressure and flow rate are set within the machine manufacturer's recommended range before initiating a cut. Avoid side-loading or using this bit in applications outside its rated material category, as carbide tooling is brittle and susceptible to fracture under improper loads.
