8mm Solid Carbide End Mill DIN 844 HR 4-Flute Long 45° Chamfer Alcrona Coated HSS-Co PM, Centre Cut, Weldon Shank - TECWERK

Benefit from the combination of wear‑resistant HSS‑Co PM construction, the protective ALCRONA coating and a secure Weldon shank for consistent performance and longer tool life; order directly via Metav Werkzeuge or request advice from our consultants for the ideal tool choice.

End mill DIN 844 Type HR, 8 mm — HSS‑Co PM, ALCRONA‑coated (TECWERK)

The End mill DIN 844 Type HR, 8 mm is a long, four‑flute cutter designed for milling steels and stainless steels with high tensile strength in production environments

• HSS‑Co PM for high wear resistance
• ALCRONA coating for improved tool life
• DIN 844 Type HR, four‑flute long version

High cutting performance in demanding materials

This long four‑flute cutter combines a HSS‑Co PM substrate and an ALCRONA surface treatment to sustain higher cutting loads while maintaining edge stability. The tool’s centre‑cutting geometry and right‑hand helix deliver efficient chip evacuation and reliable plunge capability; the tapered flute root increases rigidity and reduces chatter, which improves surface finish and dimensional control when machining tougher workpieces up to approximately 1400 N/mm² tensile strength.

Secure clamping and shop‑floor reliability

The cylindrical shank with a Weldon drive flat ensures a positive and repeatable connection to the toolholder, reducing slippage under heavy feed. The cutter’s protective 45° chamfer on the cutting edge helps prevent edge damage during entry, while the four cutting edges balance material removal rate and tool life. These design choices translate into fewer tool changes and more predictable cycle times in series production, supporting leaner processes and less downtime.

Practical suitability and application guidance

Engineered to meet the DIN 844 Type HR standard, this long end mill is very well suited to machining steel, stainless steel (INOX) and cast materials, while performance on non‑ferrous metals and certain special alloys is conditional and may require adapted cutting data. The combination of substrate and coating supports higher thermal loads and abrasion resistance, making the tool appropriate for roughing and semi‑finishing operations where stable geometry and consistent flank wear are priorities.

FAQ

Is this cutter suitable for stainless steel applications? Yes. The End mill DIN 844 Type HR, 8 mm from TECWERK is specified as very well suited for INOX and is designed to cope with the particular demands of stainless machining.

Can the tool be used for roughing and finishing operations? The long four‑flute design of this cutter supports both roughing and semi‑finishing; the combination of HSS‑Co PM and ALCRONA coating balances wear resistance with edge stability for varied tasks.

What does the Weldon shank provide compared with a plain cylindrical shank? The Weldon drive flat on this TECWERK end mill secures clamping under higher radial loads, reducing the risk of slippage and improving repeatability in production setups.

Are non‑ferrous materials and special alloys supported by this tool? Performance on non‑ferrous metals and certain special alloys is conditional; while the cutter can machine these materials, optimised cutting data may be required to achieve the best tool life.

Which standards and specifications does this cutter follow? The tool conforms to DIN 844 and is manufactured as Type HR with centre‑cut capability and a 45° protective chamfer, suitable for robust industrial use.
