Guhring 3527 Carbide Thread Mill for ISO Metric Internal Threads

The Guhring 3527 carbide thread mill is designed for high-precision ISO metric internal thread milling.
This series features solid carbide construction with helical flutes and chamfered edges, ensuring excellent surface finish, reliable chip evacuation, and stable performance on CNC lathes and machining centers.

Ideal for materials such as carbon steel, stainless steel, and non-ferrous alloys, the Guhring 3527 thread mill provides consistent ISO metric internal threads in blind and through holes.
It is suitable for turning and milling operations where precision and repeatability are critical.

Guhring 3527 Thread Mill – Suitable Applications

• Internal metric thread milling on CNC lathes and machining centers
• ISO metric threads M4 to M16 (multi-size adaptability)
• Applications requiring high precision and tight tolerances
• Materials including carbon steel, stainless steel, and non-ferrous alloys

Not recommended for

• External threading or non-ISO metric threads
• Low rigidity setups or excessive vibration
• Heavy interrupted cuts compromising stability
• Machines without internal coolant when through-coolant is required
