Guhring 9008150360000 Spiral Point Tap M36x4 Cobalt

Product Description

The GUHRING 9008150360000 is a spiral point tap designed for right-hand through-hole threading in metric M36 x 4 applications. Built from cobalt high-speed steel with a bright finish, it delivers the hardness and heat resistance required for tapping steel workpieces at larger thread diameters. The plug chamfer distributes cutting load across the leading threads for controlled entry into pre-drilled through-holes. With 5 flutes and a D8/D9 thread limit held to a 6H class of fit, this tap produces consistent thread geometry suited to production and maintenance environments. Overall length is 200 mm with a 28 mm shank diameter. Installed by machinists and tool-and-die professionals on manual or CNC equipment.

This tap is intended for through-hole threading operations on steel workpieces where M36 x 4 metric threads are required. The cobalt material construction makes it well suited for harder steel grades that generate elevated cutting temperatures. The 5-flute geometry helps distribute torque across a larger cutting surface at this diameter, reducing deflection risk during the tapping cycle. Typical applications include heavy fabrication, industrial maintenance, and machine repair where large-diameter metric threaded holes are needed in steel components.

Key Features

• M36 x 4 metric thread size with 4 mm pitch for coarse-thread through-hole applications
• Cobalt high-speed steel construction for improved heat and wear resistance in steel materials
• 5-flute design distributes cutting torque across the full tap diameter
• Plug chamfer provides controlled lead-in for through-hole threading
• 6H class of fit with D8/D9 thread limit for consistent, on-tolerance thread production
• Bright finish, no coolant-through — suited for flooded or manual lubrication setups

Compatibility

Designed for right-hand through-hole threading in steel workpieces requiring M36 x 4 metric threads. Compatible with standard tap holders and CNC rigid-tapping chucks accepting a 28 mm shank diameter.

Installation Notes

Installation should be performed by a qualified machinist following applicable shop safety procedures. Ensure the workpiece is securely fixtured and the spindle is properly aligned before beginning the tapping cycle. Use appropriate cutting fluid or tapping compound for steel to reduce heat buildup and extend tap life. Inspect the tap for wear or chipping before each use, particularly at this diameter where torque loads are significant.
