TECWERK End Mill DIN 844 Type N Ø20 mm (HSS‑Co8, TiCN, 4‑flute, Weldon)

The TECWERK End Mill DIN 844 Type N Ø20 mm is a short, centre‑cutting, four‑flute cutter designed for medium‑strength machining in toolrooms and production environments

• HSS‑Co8 substrate for high wear resistance
• TiCN coating for extended tool life
• Weldon shank with drive flat for secure clamping

Consistent cutting performance for medium‑strength materials

The HSS‑Co8 substrate provides a balance of toughness and hardness suited to demanding milling tasks; combined with a TiCN coating, tool life increases under appropriate cutting conditions. The tool is rated for work up to ≈800 N/mm² with an uncoated insert and up to ≈1000 N/mm² when coated, which supports longer intervals between changes and contributes to predictable cycle times. This reliability translates into fewer interruptions and improved throughput for everyday machining.

Secure clamping and plunge capability for precise operations

A Weldon shank with a drive flat ensures secure retention in standard toolholders, reducing slippage under higher axial forces. The centre‑cutting geometry permits limited plunge milling and drilling operations, while the four‑flute configuration balances feed rate and surface finish for side milling. Together, these features reduce vibration and improve dimensional repeatability, which is particularly important for jobs requiring tight tolerances and a consistent surface quality.

Proven suitability across common workshop materials

This short DIN 844 Type N cutter is described as very good for steel, stainless steel and cast materials, and conditionally suitable for non‑ferrous metals and special alloys. In practice, it is well suited for toolrooms, repair shops and light production where a versatile, robust end mill is required for components made from medium‑strength steels and corrosion‑resistant grades. The combination of substrate and coating makes it a practical choice when occasional higher hardness encounters are expected.

Efficiency and reduced tool management overhead

The compact form factor and robust geometry reduce tool change frequency and downtime. For daily use, the shorter overhang improves rigidity, enabling higher effective feeds at equivalent spindle speeds compared with longer cutters. This leads to better surface finishes and a more consistent workpiece outcome, supporting more efficient batch processing and less rework — a clear rational benefit for manufacturing operations with tight productivity targets.

FAQ

What materials is this cutter best suited for?
The TECWERK end mill DIN 844 Type N Ø20 mm is very well suited for steel, stainless steel and cast materials, with conditional suitability for non‑ferrous metals and special alloys.

Can this tool be used for plunge milling?
Yes, the centre‑cutting geometry of this short, four‑flute end mill allows plunge operations and limited drilling when appropriate feeds and speeds are observed.

What shank type and clamping does the tool require?
The cutter features a Weldon shank with a drive flat for secure clamping in standard Weldon‑type holders; this improves retention under axial and radial loads.

How does the TiCN coating affect performance?
The TiCN coating increases wear resistance and thermal stability, enabling higher performance in tougher materials and extending tool life compared with an uncoated equivalent.

Is the cutter suitable for high‑hardness steels?
The TECWERK HSS‑Co8 tool is intended for work up to approximately 800 N/mm² uncoated and up to about 1000 N/mm² when coated; for substantially harder materials, alternative tool grades should be considered.
