Guhring 9028760100000 Spiral Point Tap M10x1.5 Cobalt

Product Description

The GUHRING 9028760100000 is a cobalt spiral point tap designed for cutting metric internal threads in through-hole applications. Built to M10 x 1.5 specification with a 6H class of fit and D4/D5 thread limit, this plug-chamfer tap drives chips forward ahead of the cutting zone, making it well suited for through-hole threading operations. The cobalt construction provides elevated heat resistance and edge retention compared to standard high-speed steel, and the oxide finish aids in initial lubrication and corrosion resistance. With a 100 mm overall length and a 10 mm shank diameter, it fits standard toolholders used on CNC machining centers, drill presses, and tapping heads in production and job-shop environments. Installation and operation are handled by machinists and toolroom technicians.

This tap is rated for use in stainless steel and steel workpieces, materials that demand a harder, more wear-resistant tap substrate. The plug chamfer provides a gradual entry lead suitable for through-hole threading where the tap can pass completely through the bore. The right-hand thread direction aligns with standard M10 x 1.5 fastener specifications common across general mechanical assemblies, machine frames, and structural components. It is part of GUHRING Series 2876 and ships as a single tap per package.

Key Features

• Cobalt substrate for improved wear resistance and heat tolerance when tapping stainless steel and steel
• Spiral point geometry drives chips forward, keeping flutes clear in through-hole applications
• Oxide finish aids lubrication retention and reduces initial friction at thread engagement
• Plug chamfer provides gradual entry lead for clean thread starts in through-hole bores
• 6H class of fit and D4/D5 thread limit for standard metric tolerance requirements
• 3-flute design balances chip evacuation and cutting edge rigidity in moderate-to-hard materials

Compatibility

Designed for through-hole threading in stainless steel and steel workpieces requiring an M10 x 1.5 metric thread with a 6H class of fit. Compatible with standard straight-shank tapping chucks and floating tap holders accepting a 10 mm shank diameter.

Installation Notes

This tap is installed and operated by machinists using CNC machining centers, drill presses, or dedicated tapping machines equipped with a proper floating or rigid tap holder. Always confirm spindle speed and feed rate are appropriate for the workpiece material and tap diameter before engaging the cut. Use a cutting fluid or tapping compound rated for the workpiece material, particularly when tapping stainless steel, to extend tool life and maintain thread quality. Inspect the tap for wear or chipping after each use and replace before thread quality degrades.
