Guhring 9057460097000 Taper Length Drill Bit 9.7mm

Product Description

The GUHRING 9057460097000 is a taper length drill bit from the Series 5746 line, engineered for demanding drilling applications in difficult-to-machine materials. Built from K40-grade solid carbide and finished with a nano-A coating, this bit delivers superior wear resistance and thermal stability under high-load conditions. It measures 9.7 mm in diameter (0.3819 inches) with a 140-degree split point (SU type) and a web-thinned geometry that reduces thrust force at entry. The 95 mm flute length and 139 mm overall length put it in taper length territory, and the straight cylindrical shank at 10 mm diameter allows mounting in standard toolholders. Coolant-through capability supports high-speed production environments. Installed by machinists and toolroom technicians in CNC and manual drilling operations.

This drill bit is designed for cutting stainless steel, nickel alloys, and titanium alloys — material groups known for work hardening and heat generation at the cutting edge. The 7xD flute-length-to-diameter ratio and regular spiral flute geometry promote consistent chip evacuation in deep-hole applications in these tough materials. A right-hand cutting direction and straight shank make it compatible with standard drill chucks and collet systems across CNC machining centers, drill presses, and manual machine tools used in aerospace, medical device, and industrial manufacturing environments.

Key Features

• K40-grade solid carbide construction for high hardness and wear resistance in abrasive materials
• nano-A coating reduces friction and extends tool life in stainless steel, nickel alloy, and titanium alloy applications
• 140-degree SU split point with web thinning reduces entry thrust and prevents walking
• Coolant-through design supports internal coolant delivery for deep-hole drilling and heat control
• 7xD flute-length-to-diameter ratio enables deep reach with consistent chip evacuation
• Straight cylindrical shank at 10 mm diameter with m7 diameter tolerance fits standard toolholders

Compatibility

Designed for use in stainless steel, nickel alloy, and titanium alloy workpieces. Compatible with standard straight-shank drill chucks, ER collet systems, and hydraulic toolholders accepting a 10 mm shank diameter across CNC machining centers and conventional drill presses.

Installation Notes

Installation and tool changes should be performed by qualified machinists with the machine powered down and in a locked-out state per applicable lockout/tagout procedures. Confirm the toolholder bore and runout before seating the shank to maintain the m7 diameter tolerance and prevent premature tool failure. When using coolant-through capability, verify that the machine spindle and toolholder are configured to deliver internal coolant at the appropriate pressure for the material being drilled. Inspect cutting edges for wear or chipping before each use, particularly when working with work-hardening alloys.
