End mill DIN 844 Type HR, Ø8 mm — HSS‑Co5, TiCN, Weldon shank (TECWERK)

A End mill DIN 844 Type HR, Ø8 mm designed as a short, centre‑cutting four‑flute tool for robust general machining and reliable finishing across steel and cast‑iron work

• HSS‑Co5 base for high toughness
• TiCN coating for extended tool life
• Weldon shank with drive flat
• DIN 844 Type HR, four‑flute geometry

Increased productivity through stiff geometry and coating

The combination of a HSS‑Co5 substrate and a TiCN surface treatment provides a balanced approach to wear resistance and toughness. The four flutes reduce radial run‑out and increase rigidity, which helps maintain a consistent surface finish during interrupted cuts. With an effective length of 25 mm and a cutting diameter of Ø8 mm, the tool suits short‑reach milling operations where stability and repeatable tool life are essential. The low‑friction coating lowers built‑up edge formation and contributes to higher allowable cutting parameters when machining tougher materials.

Secure clamping and reliable torque transmission

A Weldon shank with a drive flat and a 10 mm shank diameter delivers positive torque transmission in standard Weldon holders and chucking systems. The solid shank geometry minimises slippage during high feed conditions and supports accurate concentricity over longer production runs. The overall length of 69 mm gives a compact working envelope while the short profile and 45° chamfer improve entry conditions and reduce axial thrust during engagement, which both help to preserve cutter geometry and workpiece tolerances.

Material suitability and practical application scope

Designed as a Type HR end mill under DIN 844, the tool is very well suited for steel and cast iron and is conditionally applicable to non‑ferrous metals, special alloys and stainless steel. The geometry includes a centre cutting design that permits limited plunging, useful for pocket starts or dwell corrections without a separate drill operation. For uncoated use, the tool handles materials up to approximately 800 N/mm²; with the TiCN coating applied, the capability extends up to around 1,200 N/mm², enabling a broader range of workshop tasks with one tool type.

Simple operational guidance to extend performance

To make the most of the cutter’s construction and finish, select feeds and speeds appropriate to the machine rigidity and workpiece material, and favour incremental depth passes rather than deep single cuts. Use suitable coolant or cutting fluid for ferrous materials to reduce thermal load; in dry or semi‑dry applications the TiCN layer helps to control friction and adhesion. Regular inspection of the cutting edges and correct holder clamping will preserve concentricity and ensure consistent component quality over time.

FAQ

Is this cutter suitable for stainless steel applications? The TECWERK end mill is conditionally suitable for stainless steel; performance depends on cutting parameters, coolant use and material grade, with best results achieved using the TiCN coating and conservative feeds.

Can the tool perform plunge cuts? Yes — the centre‑cutting geometry allows limited plunging and pocket entry operations, so separate pre‑drilling is not always required for shallow starts.

Which holders are compatible with the Weldon TW shank? The Weldon shank with drive flat fits standard Weldon tool holders and collet chucks designed for a 10 mm shank; secure clamping is recommended to preserve concentricity.

What distinguishes the Type HR geometry under DIN 844? Type HR denotes a short, robust profile with a protective chamfer and geometry optimised for interrupted cuts and increased rigidity, beneficial in many workshop milling scenarios.

How does the TiCN coating affect tool life? The TiCN layer reduces friction and adhesion, typically increasing tool life and allowing higher cutting parameters compared with uncoated equivalents, especially in harder steels
