TECWERK End mill DIN 844 Type HR, 8 mm — HSS‑Co5, Weldon shank

The End mill DIN 844 Type HR, 8 mm is a short, four‑flute, centre‑cutting milling cutter suited to precision slotting and plunge operations in harder materials.

• HSS‑Co5 high-speed steel for durability
• DIN 844, Type HR four‑flute design
• Weldon shank with drive flat
• Centre‑cutting; 45° protective chamfer

Precision and material capability for demanding cuts

The tool is produced from HSS‑Co5, a cobalt‑alloyed high‑speed steel that raises red‑hardness and wear resistance compared with standard HSS, enabling higher cutting temperatures and extended service life. As a four‑flute short cutter with centre‑cutting geometry, it is suitable for axial entries and reliable plunge operations. The specification includes ratings for material strength of 800 N/mm² with an uncoated tool and up to 1200 N/mm² when used with a compatible coating, which supports informed tool selection for tougher workpiece classes.

Geometry engineered for stability and surface finish

Conforming to DIN 844 Type HR, the cutter combines a compact 25 mm cutting length with a finely re‑ground helix profile to reduce burr formation and improve surface quality in the finished component. A 45° protective chamfer mitigates chipping at the margin during interrupted cuts, while the Weldon shank with drive flat ensures secure clamping and positive torque transfer in milling holders. These attributes contribute to consistent runout behaviour and repeatable concentricity during moderate feeds and speeds.

Practical benefits and typical applications in production

Designed primarily for machining steel and cast iron (very good suitability) and conditionally for non‑ferrous metals, the short design is ideal for precision slotting, pocketing and compact fixture work where rigidity is at a premium. Supplied as a single unit, the cutter reduces inventory complexity and supports predictable tool‑change planning. The combination of material grade, edge treatment and shank design helps to shorten cycle times by enabling stable, chatter‑resistant cuts and reliable surface tolerance outcomes.

FAQ

What materials is the End mill DIN 844 Type HR suitable for?
The End mill DIN 844 Type HR (TECWERK, SKU 2000866492NW) is very well suited to steel and cast iron and is conditionally suitable for certain non‑ferrous metals depending on chip evacuation and feed‑rate settings.

Can the cutter perform plunge cuts and axial entries?
Yes, the cutter’s centre‑cutting geometry allows reliable plunge operations and axial entries, which is why the End mill DIN 844 Type HR is specified for pocketing and slotting where axial engagement is required.

How does the Weldon shank benefit clamping and torque transmission?
The Weldon shank with a drive flat provides positive torque transfer and secure clamping in standard milling holders, reducing slipping and improving repeatable concentricity for the TECWERK end mill.

What advantage does HSS‑Co5 offer for production use?
HSS‑Co5 increases red‑hardness and wear resistance compared with standard high‑speed steel, enabling the End mill DIN 844 Type HR to withstand higher cutting temperatures and extend tool life under demanding conditions.

Is the cutter available as a coated version for harder materials?
The product data for the End mill DIN 844 Type HR indicates performance comparisons for uncoated and coated scenarios (up to 1200 N/mm² with coating); for coated variants or specific coating recommendations, refer to Metav Werkzeuge for matched tool options and compatibility advice.
