12mm Long Solid Carbide Roughing End Mill TiAlN Coating 35mm Cutting Length 45° Helix Right-Hand - TECWERK

The combination of a TiAlN coating and VHM (solid carbide) construction delivers high heat resistance and extended edge life, while the positive rake and special roughing profile enable vibration‑reduced material removal and consistent stock removal rates; order the TECWERK carbide roughing end mill directly via Metav Werkzeuge or consult our specialists if technical advice is required.

TECWERK Carbide Roughing End Mill DIN 6527L — D 12 mm, TiAlN, VHM

The TECWERK carbide roughing end mill DIN 6527L (D 12 mm, long) is a high‑performance tool designed for heavy roughing operations in steel, non‑ferrous metals and cast parts.

• VHM solid carbide construction
• TiAlN coating for high heat resistance
• 45° helix for efficient chip evacuation
• DIN 6535 HB shank, tolerance h6

Fast, durable roughing with reduced vibration

The long solid‑carbide design combines VHM material properties with a TiAlN surface layer to sustain high temperatures and resist abrasion during demanding operations. The tool’s special roughing profile and four flutes remove large chip volumes while maintaining stability; this results in vibration‑reduced cutting that prolongs tool life and preserves machine spindle health. The positive rake angle promotes predictable cutting forces, which helps to maintain cycle times and reduces the need for frequent tool changes.

Broad material compatibility with clear performance advantages

A 45° helix and the optimised flute geometry ensure reliable chip control across a range of materials: excellent performance in steel, non‑ferrous metals and castings, and conditional suitability for stainless and certain special alloys. The combination of the 45° helix angle and the cutter’s roughing profile enables efficient chip evacuation, lowering the risk of built‑up edge and improving process repeatability. Where higher heat and abrasion are expected, the TiAlN coating provides a thermal barrier that supports higher cutting parameters and consistent surface results.

Secure mounting and long‑reach geometry for versatile setups

The tool follows the DIN 6527L form with a cylindrical shank to DIN 6535 HB and h6 shank tolerance for reliable clamping and concentricity. With a 12 mm shank and an effective reach of 35 mm, the long version is suited for deep pocketing and stepped components while keeping runout low. The 45° protective chamfer and neck relief reduce interference and allow approach from limited access angles; this geometry supports flexible fixturing and helps maintain consistent tool engagement during heavy passes.

FAQ

What materials is this roughing end mill best suited for?
The TECWERK carbide roughing end mill is very well suited to steel, non‑ferrous metals and cast materials; it is conditionally suitable for stainless steel and certain special alloys (SKU 2000866119NW).

How does the TiAlN coating benefit performance?
The TiAlN coating on this TECWERK VHM tool increases thermal stability and wear resistance, allowing higher cutting temperatures and longer edge life for sustained roughing operations.

What advantages does the 45° helix provide?
A 45° helix angle improves chip thinning and evacuation, reducing cutting forces and supporting stable material removal in the roughing profile of the TECWERK cutter.

Is the shank suitable for standard collets and holders?
Yes, the cylindrical shank to DIN 6535 HB with h6 tolerance ensures precise clamping in standard toolholders, providing concentricity and secure mounting for deep or long‑reach operations.

How does the roughing profile affect cycle times?
The special roughing profile with four cutting edges promotes efficient chip breaking and high material removal rates while limiting vibration, which in practice reduces cycle time by allowing higher feed per tooth and fewer tool changes.
