TECWERK End Mill DIN 6527L, 12 mm — Solid Carbide, TiAlN Coated, Long, 38/40° Helix

TECWERK End Mill DIN 6527L is a long solid‑carbide milling cutter engineered for efficient roughing and refined finishing of non‑ferrous workpieces in production and toolroom environments

• Solid carbide with TiAlN coating
• Unequal helix for low vibration machining
• Z=3 centre‑cutting flutes for ramping and plunge milling
• Cylindrical shank to DIN 6535 HB specification

Precision, stability and surface quality thanks to unequal‑pitch geometry

The long solid‑carbide cutter delivers a stable cut sequence through its unequal helix and three‑flute layout, reducing harmonic excitation during machining. The Z=3 configuration with a 38/40° helix angle enables high feed rates while preserving surface integrity, so components emerge with a consistent finish. This geometry is particularly beneficial when processing elongated features or deep pockets, where chatter and tool deflection otherwise degrade results. The design therefore supports both productivity gains and predictable component quality.

Coating and cutting edge design minimise built‑up edge and weld‑on

A specialised TiAlN coating is applied to protect the cutting edges and to reduce material adhesion when machining aluminium, copper and other non‑ferrous metals. The cutter is centre cutting, allowing controlled plunging and ramping operations, and includes a small 45° protection chamfer and a 0.2 mm edge relief to discourage burr formation. Together, these features reduce the risk of built‑up edge and prolong tool life, making the tool suitable for mixed batches and applications where repeatable surface finish is required.

Shank standard and application versatility for workshop integration

Equipped with a cylindrical shank produced to DIN 6535 HB, the long variant is compatible with standard toolholders and collet chucks used across industrial workshops. A neck relief grind improves clearance when machining deep cavities, while the right‑hand cutting configuration matches conventional spindle rotations. The combination of solid‑carbide construction and the special coating ensures stable performance for both roughing and finishing passes, offering an economical route to fewer tool changes and consistent throughput.

FAQ

What materials is the end mill best suited to?
The TECWERK end mill is optimised for aluminium, copper and other non‑ferrous metals, providing very good performance on these materials thanks to the TiAlN coating and flute geometry.

Can the cutter be used for plunge milling?
Yes, the cutter features a centre‑cutting geometry that allows controlled plunging and ramping operations with the long solid‑carbide design.

How does the unequal helix affect machining?
The unequal helix reduces harmonic resonance during cutting, which leads to a vibration‑reduced run and improved surface finish suitable for higher feeds and consistent part quality.

Is the shank compatible with standard toolholders?
The cylindrical shank is produced to DIN 6535 HB, ensuring compatibility with commonly used collet chucks and holders in industry toolrooms.
