Guhring 9064050023500 Micro Drill Bit 2.35mm Carbide

Product Description

The GUHRING 9064050023500 is a solid carbide micro drill bit engineered for precision drilling in demanding materials. It features a 2.35 mm (0.0925 inch) diameter, a 140-degree faceted point angle, and a TiAlN coating that extends tool life at elevated cutting temperatures. A through-coolant design delivers cutting fluid directly to the tip, reducing heat buildup and improving chip evacuation in deep-hole applications. The overall length is 62 mm with a 19 mm flute length and a maximum drilling depth of 16.10 mm. The straight-cylindrical shank measures 4.00 mm in diameter for secure chuck retention. This bit is sized and specified for use by machinists and tool-and-die professionals working in precision manufacturing environments.

This micro drill bit is designed for right-hand, spiral-flute cutting in ferrous and non-ferrous workpiece materials. Primary workpiece materials include cast iron, stainless steel, and steel (ISO material codes K, M, P). Secondary workpiece materials include aluminum and titanium alloy (ISO codes N, S). The 5xD flute-to-diameter ratio and web-thinned geometry reduce thrust force at entry, making this bit well suited for small-diameter, tight-tolerance holes in production machining, aerospace component work, and precision fabrication.

Key Features

• 2.35 mm diameter with a 0.0925 inch decimal equivalent for direct imperial cross-reference
• TiAlN coating resists heat and wear during high-speed cutting in hard materials
• Through-coolant construction channels fluid to the cutting edge for improved chip removal and tool life
• 140-degree faceted point with web-thinning reduces cutting force and improves centering accuracy
• Solid carbide K40 grade substrate provides rigidity and edge retention in micro-diameter applications
• Straight-cylindrical shank with m7 diameter tolerance ensures consistent, repeatable chuck seating

Compatibility

Designed for use in CNC machining centers and drilling stations equipped with through-coolant capability. Confirmed primary workpiece materials are cast iron, stainless steel, and steel; secondary workpiece materials are aluminum and titanium alloy. Part of the Guhring Series 6405 micro drill line.

Installation Notes

Installation and tool changes should be performed by qualified machinists with the spindle fully stopped and machine power isolated. Verify chuck or collet bore matches the 4.00 mm shank diameter before seating. Confirm through-coolant pressure and flow rate are within the machine and toolholder specifications before initiating a cut. Inspect the cutting edge under magnification prior to use, as micro-diameter carbide tools are brittle and sensitive to chipping from improper handling.
