End mill DIN 844 Type N D16 mm (HSS‑Co PM, ALCRONA) — TECWERK

The End mill DIN 844 Type N D16 mm (HSS‑Co PM, ALCRONA) is a long, centre‑cut, right‑hand four‑flute cutter designed for milling steel, stainless steel and cast iron up to approximately 1000 N/mm².

• HSS‑Co PM substrate for high toughness
• ALCRONA coating for extended life
• Weldon shank for secure clamping
• Four unevenly pitched flutes reduce vibration

Consistent performance for medium‑strength materials

The combination of a HSS‑Co PM substrate and ALCRONA coating delivers a balance of toughness and wear resistance that benefits everyday workshop production. The long version to DIN 844 Type N offers extended reach without sacrificing rigidity, enabling consistent material removal rates in components made from steel, stainless steel and cast iron, for which the tool is rated as very good. The centre‑cutting geometry allows limited plunge milling while preserving edge integrity.

Stability and vibration control for better surface quality

A major practical advantage is the tool’s vibration reduction through unevenly pitched, four‑flute geometry combined with a tapered flute root that increases stiffness. The result is fewer chatter marks and an improved surface finish on workpieces; this supports tighter process windows and reduces rework. The Weldon shank (drive flat) ensures dependable torque transmission and secure clamping in common toolholders, which is essential for repeatable cycle times in production.

Coating and substrate: what they mean in practice

The ALCRONA finish acts as a protective barrier that lowers abrasive wear and helps maintain cutting edge sharpness under intermittent cutting loads. Paired with the HSS‑Co PM core, the cutter resists thermal and mechanical stresses better than conventional high‑speed steels, extending tool life in batch and single‑piece production alike. For less experienced users: the coating reduces built‑up edge, while the cobalt‑alloyed substrate provides the fracture resistance needed when entering and exiting slots.

Application tips for reliable results

Designed as a right‑hand, centre‑cutting, four‑flute end mill with a cylindrical shank and drive flat, this long‑reach tool is particularly effective for shoulder milling, slotting and finishing operations where access depth is critical. Feed and speed should be chosen with material hardness and machine rigidity in mind; the cutter is specified for materials up to about 1000 N/mm². Note the conditional suitability for non‑ferrous metals and special alloys — test cuts are recommended when processing these materials to fine‑tune parameters and secure optimal chip evacuation.

FAQ

Which materials is this cutter best suited for?
The TECWERK end mill DIN 844 Type N D16 mm is rated very good for steel, very good for stainless steel and very good for cast iron; it is conditionally suitable for non‑ferrous metals and special alloys.

Can the cutter perform plunge cuts?
The centre‑cutting geometry permits limited plunge operations; however, controlled feed and appropriate spindle power are required when plunging with this long‑reach cutter.

What benefits does the ALCRONA coating provide?
The ALCRONA coating reduces abrasive wear and helps prevent built‑up edge, extending cutting life and improving finish on long‑reach milling tasks.

How should the cutter be clamped?
Use a secure holder compatible with a Weldon drive flat to ensure reliable torque transmission and minimise slippage during heavy cuts.

Is this tool suitable for high‑speed machining?
The HSS‑Co PM substrate is robust but process parameters must be adapted to machine rigidity and workpiece material; testing is advised when increasing cutting speeds.
