TEX Square End Mill for Stainless Steel

The TEX square end mill is specially developed for stainless steel machining, especially for dynamic milling, roughing, and semi-finishing applications. With optimized core geometry and advanced AlCrN coating, it delivers stable chip evacuation, lower vibration, and reliable thermal stability in stainless steel cutting.

Compared with general-purpose end mills, TEX series tools are designed to handle the cutting resistance, heat concentration, and built-up edge risks commonly found in stainless steel machining. This makes them more suitable for stable cutting performance in slotting, side milling, and pocket machining.

For a broader comparison of cutter geometries used in stainless steel machining, see our guide to stainless steel end mill types and how to choose the right one.

The table below lists standard sizes of the Dohre TEX series square end mill for stainless steel machining. Custom sizes and geometries are also available based on your application requirements.

Standard Size Overview

Premium Carbide Material

The TEX square end mill uses ultra-fine micro-grain carbide below 0.6 μm with 12% cobalt content. This material provides a balanced combination of hardness, toughness, and wear resistance, helping the tool maintain stable performance in stainless steel machining.

Balzers AP Coating

The cutter uses Balzers AP coating based on AlCrN technology, with heat resistance up to 1200°C. The coating offers strong hardness, oxidation resistance, and wear resistance, making it more reliable in high-temperature stainless steel cutting conditions.

Optimized Dual-Core Geometry

The tool adopts a dual-core design, with the first core opened to 52% and the second core to 70%, combined with an 8° rake angle and 45° helix angle. The smaller front core helps improve chip evacuation during roughing, remove cutting heat more effectively, and reduce the risk of built-up edge.

Unequal Pitch for Lower Vibration

The unequal pitch design of 88° / 92° effectively suppresses cutting vibration and improves machining stability. This makes the tool especially suitable for roughing and dynamic milling, while also helping achieve smoother cutting and more consistent machining results.

Dohre CNC pays close attention to edge preparation, dimensional consistency, and inspection standards in stainless steel machining applications. TEX series end mills are produced under strict control to ensure stable cutting performance, consistent edge quality, and reliable batch accuracy.

We use a fluid sandblasting process to reduce burrs on the cutting edge and improve the final surface quality of machined parts. This helps the tool achieve more stable cutting performance in stainless steel semi-finishing applications.

The cutting edges are treated by a fully automatic passivation machine with rubber-bonded diamond abrasive polishing. This process helps maintain edge consistency across all tools, and the passivation value can be controlled within ±3 μm.

Profile measurement is carried out using German Walter HELICHECK PLUS equipment, together with 150× optical inspection and 300× high-definition appearance inspection. This helps ensure stable tool geometry, reliable cutting edge quality, and consistent batch production.

TEX series end mills are produced on German Walter 5-axis high-precision grinding machines. This helps maintain cutting edge sharpness and dimensional accuracy, making cutting smoother and more stable in stainless steel machining.
