Guhring 3541 Carbide Helical Flute Thread Mill for Internal Threading

The Guhring 3541 series carbide helical flute thread mills are precision solid carbide tools designed for efficient internal metric thread milling on CNC lathes and machining centers.
Featuring multi-range thread profiles and four flutes, these thread mills provide high accuracy, excellent surface finish, and reliable performance across a wide range of internal thread sizes.

Ideal for ISO metric internal threads on materials including carbon steel, stainless steel, and non-ferrous alloys, the 3541 series reduces setup time while maintaining consistent thread quality.
These tools are widely used in precision machining setups where repeatability and thread integrity are critical. For turning and milling operations, this series ensures stable and accurate internal threading.

Suitable for

• Internal metric thread milling on CNC lathes and machining centers
• ISO standard threads with multi-range profile adaptability
• Workshops requiring high repeatability and precise internal threads
• Materials such as carbon steel, stainless steel, and non-ferrous alloys

Not recommended for

• External threading or non-ISO thread standards
• Low-rigidity machines or setups prone to vibration
• Applications without through-coolant capability where internal coolant is necessary
• Custom or specialized thread forms outside the standard 3541 profile

Key Specifications & Technical Notes

• Series: 3541, Type TMU SP, solid carbide, multi-range internal thread mill
• Four-flute helical design for optimized chip evacuation and surface finish
• Adaptable for a broad range of ISO metric internal threads
• Solid carbide construction ensures rigidity and wear resistance
• Check machine setup and rigidity before high-speed or heavy interrupted operations

FAQ / Common Questions

• Q: Can the 3541 series be used for fine internal threads on stainless steel
  A: Yes — the carbide material and helical flute design maintain surface finish on stainless steel. Technical confirmation is recommended for exact pitch and material combination.
• Q: Is through-coolant support necessary
  A: For optimal chip evacuation and tool life, machines with internal coolant are recommended.
• Q: Can one 3541 tool cover multiple thread sizes
  A: The multi-range profile allows adaptability, but confirm specific thread size and pitch with our technical team before ordering.

Technical Confirmation Recommended

Before ordering a Guhring 3541 series thread mill, please confirm your threading requirements to ensure correct fit and performance.

Please provide the following details for technical verification:

• Machine type and spindle interface
• Thread size and pitch to be machined
• Workpiece material and coolant availability

Our technical team will verify compatibility and provide recommendations prior to quotation.
