Guhring 9006090030000 Carbide Drill Bit 3mm Tin

Product Description

The GUHRING 9006090030000 is a solid carbide jobber-length drill bit designed for precision drilling in demanding industrial and trade applications. Built to DIN 6539 standards, this 3 mm (0.1181 inch) diameter bit features a Titanium Nitride (TiN) coating that extends tool life by reducing friction and heat buildup at the cutting edge. The 150-degree drill point angle and web-thinned, tapered web configuration promote self-centering entry and cleaner hole initiation without a center punch. With a submicron carbide grade and three-flute spiral design, the bit delivers improved chip evacuation and higher feed rates compared to standard two-flute geometry. Licensed machinists, toolmakers, and precision fabricators are the primary installers of this bit in CNC and manual drilling operations.

This bit is suited for drilling small-diameter, close-tolerance holes in hard materials including hardened steels, cast iron, stainless steel, and exotic alloys. The straight-cylindrical shank (0.1181 inch diameter) fits standard collet chucks and drill chucks on CNC machining centers, CNC lathes with live tooling, and precision bench drill presses. The 5xD flute-to-diameter ratio supports a maximum drilling depth of 0.690 inch (17.50 mm) per pass without coolant-through capability, making it appropriate for shallow-to-moderate depth holes in production and toolroom environments. Series 609 is GUHRING's line of solid carbide jobber bits optimized for rigid machine setups.

Key Features

• Solid submicron carbide construction for strength and wear resistance in hard materials
• TiN coating reduces cutting friction and extends tool life between resharpenings
• 150-degree point angle with web thinning promotes self-centering and reduces thrust force
• Three-flute spiral geometry improves chip evacuation at higher feed rates
• DIN 6539 standard compliance ensures dimensional consistency and interchangeability
• Straight-cylindrical shank fits standard collet and drill chucks without adapters

Compatibility

Designed as an OEM-style replacement or direct-fit tooling solution for any machine tool accepting a straight-cylindrical shank drill in the 3 mm (0.1181 inch) diameter range, including CNC machining centers, lathes with live tooling, and precision drill presses using standard ER or drill chucks.

Installation Notes

Installation of this bit should be performed by a qualified machinist or toolroom technician. Ensure the machine spindle is fully stopped and the chuck or collet is clean and free of debris before seating the shank. Confirm runout is within acceptable limits for the application, as excessive runout accelerates wear on small-diameter carbide tools. Carbide bits are brittle relative to HSS; avoid side-loading or interrupted cuts that can cause fracture.
