Guhring 9005460060000 Spotting Drill 6mm 142 Degree Solid Carbide

Product Description

The GUHRING 9005460060000 is a solid carbide spotting drill designed to accurately locate and start holes before a twist drill or boring operation. It runs a 142-degree point angle, which is a geometry suited to general-purpose spotting on a wide range of workpiece materials. The 6 mm cutting diameter and 16 mm flute length keep the tool stiff and minimize deflection at entry. A bright, uncoated finish means the carbide substrate is exposed directly to the cut, making this a practical choice when coatings are unnecessary or when regrinding is planned. Machinists and CNC operators install this tool in drill chucks or collet-style toolholders on machining centers and drill presses.

This spotting drill is intended for general-purpose drilling applications in production and job-shop environments. The right-hand cutting direction and spiral flute geometry suit standard spindle rotation on vertical machining centers and drill presses. The Weldon flat shank provides a positive drive connection and resists pullout under repeated spotting cycles. The 6 mm shank diameter matches the cutting diameter, keeping the tool profile clean and minimizing interference in close-clearance setups. Series 546 is a GUHRING line aimed at general metalworking and light production use.

Key Features

• 142-degree point angle for accurate, low-thrust hole location across common workpiece materials
• Solid carbide construction provides stiffness and wear resistance
• Bright, uncoated finish suitable for dry cutting or when specialty coatings are not required
• Weldon flat shank for positive drive and reduced pullout risk
• Two-flute spiral design promotes chip clearance during spotting cycles
• Single-ended design; compatible with standard drill chuck and collet toolholding systems

Compatibility

Designed as an OEM-style general-purpose spotting drill compatible with toolholders accepting a 6 mm Weldon flat shank, including collet chucks, Weldon-style end mill holders, and hydraulic chucks sized for 6 mm shanks.

Installation Notes

A licensed machinist or CNC operator should install and qualify this tool. Secure the Weldon flat in the toolholder setscrew against the flat before torquing to the toolholder specification. Power down and lock out the spindle before changing tools. Verify runout at the cutting diameter after installation and before the first production cycle; excessive runout will degrade spot accuracy and shorten tool life.
