TECWERK End Mill DIN 844 Type N — 20 mm, HSS‑Co PM with ALCRONA coating (Weldon shank, 4 flutes, long)

A TECWERK end mill DIN 844 Type N designed for deep and precise milling of steels and stainless steel, featuring a Weldon shank and vibration‑reducing flute geometry

• HSS‑Co PM construction for high strength
• ALCRONA coating for reduced wear
• Long design with Weldon shank for deep cuts
• Four flutes with unequal split for vibration control

Precision and lifetime for demanding steel work

The long, high‑performance cutter delivers consistent chip evacuation and extended tool life thanks to its HSS‑Co PM substrate and ALCRONA coating. The powder‑metallurgical high‑speed steel core increases red‑hardness and fracture resistance, which makes this cutter particularly suitable for milling tasks in steels up to approximately 1000 N/mm². The combination of substrate and coating reduces flank wear and maintains cutting geometry over longer series runs, ensuring predictable process windows in production environments.

Stable milling performance and vibration reduction

Built to the DIN 844 standard as a Type N long end mill, the tool features a Weldon shank for secure clamping and a four‑flute design with unequal flute division to lower resonance. The offset flute spacing reduces chatter and improves surface finish in deep cuts, while the conical flute root increases overall tool stiffness. For workshops and jobbing shops seeking repeatable results, this geometry translates into fewer reworks and better adherence to machining tolerances.

Clear suitability and material guidance

Application suitability has been optimised for a wide range of materials: excellent for steel and stainless steel, very good for cast iron and conditionally suitable for non‑ferrous metals and special alloys. The cutter is centre‑cutting, so it can plunge as well as mill across the face. The right‑hand cutting direction conforms with standard machining setups. These characteristics make the tool a practical choice for serial production and repair work where adaptability and robustness are required.

Practical design details that aid handling and setup

Key dimensions and functional choices support both manual and CNC workflows: a 20 mm diameter and 20 mm shank permit direct holder mounting, while the Weldon flat enhances torque transmission for interrupted cuts. The modest cutting length relative to the overall length keeps the effective tool overhang low, improving rigidity during long‑reach operations. The product’s configuration allows easy integration into existing tool pages and simplifies tool life tracking in structured maintenance plans.

FAQ

What materials is this end mill best suited for?
The TECWERK end mill DIN 844 Type N is very well suited for steel and stainless steel applications and is also very good for cast iron; suitability for non‑ferrous metals and special alloys is conditional.

Can the tool be used for plunge milling?
Yes. The cutter is centre‑cutting, so the TECWERK long end mill can be used for plunging as well as conventional side milling operations.

What advantages does the ALCRONA coating provide?
The ALCRONA coating on this HSS‑Co PM cutter reduces abrasive wear and extends tool life under elevated temperatures common in steel machining.

How does the Weldon shank benefit production use?
The Weldon shank improves clamping security and torque transmission for interrupted cuts, making the cutter reliable in both manual setups and CNC toolholders.

Is the tool designed to reduce vibration and chatter?
Yes. Unequal flute division and a conical flute root increase stiffness and lower resonance, improving surface finish and dimensional stability.
