TECWERK D844 Type N end mill — HSS‑Co8, TiCN, Ø14 mm, long

The D844 Type N end mill is a long, 4‑flute HSS‑Co cutter designed for slotting and finishing on steel and stainless steel in accordance with DIN 844.

• HSS‑Co8 for improved wear resistance
• TiCN coating for higher cutting performance
• Long 63 mm cutting length for deep slots
• Weldon shank with drive flat for secure clamping

High precision and consistent surface quality for production use

Made from HSS‑Co8 and specified to DIN 844, this long milling cutter offers a balance of toughness and wear resistance suited to industrial environments. The Ø14 mm body and 63 mm cutting length provide reach for deeper operations while the 4‑flute geometry reduces vibration and supports a stable cutting action. In practice, this means fewer tool changes and more predictable component tolerances, which contributes to smoother production flow and reduced rework.

Coating and strength: longer tool life under increased loads

The TiCN coating increases surface hardness and heat resistance, enabling the tool to handle higher workpiece strengths compared with an uncoated variant. Where an uncoated tool is suitable up to about 800 N/mm², the coated version extends applicability to approximately 1200 N/mm², expanding the range of machinable alloys. Suitability is highlighted by especially good performance on steel, stainless steel, and cast iron, while non‑ferrous and special alloys show more limited compatibility.

Secure clamping and versatile machining strategies

A Weldon shank with drive flat gives dependable axial and torsional support in standard tool holders, reducing slippage during interrupted cuts. The centre‑cutting design allows plunge and ramp moves in addition to conventional side milling, and the right‑hand cutting orientation delivers predictable chip flow. For shop floors requiring both slotting and finishing with minimal setup time, the long reach of this cutter supports efficient single‑setup machining where previously multiple tools might have been needed.

Practical benefits for purchasing and production planning

Compliance with DIN 844 ensures dimensional reliability and interchangeability across tool holders and collets. The combination of HSS‑Co substrate and TiCN surface treatment provides a cost‑effective alternative to more specialised grades while maintaining excellent surface finish and tool life in many standard applications. For production planners and buyers, the result is improved machining efficiency and consistent finishes on routine and semi‑demanding workpieces.

FAQ

Is this cutter suitable for plunge milling?
Yes. The D844 Type N end mill from TECWERK is centre‑cutting, which permits plunge and ramp milling in addition to axial profiling.

What materials can be machined with this tool?
The TECWERK D844 end mill performs very well on steel, stainless steel, and cast iron; suitability for non‑ferrous and special alloys is limited according to the tool’s specifications.

Does the TiCN coating improve performance?
The TiCN coating on the TECWERK D844 increases surface hardness and heat resistance, extending application capability to higher workpiece strengths (approx. 1200 N/mm² when coated).

What clamping system is required for this tool?
The tool has a Weldon shank with drive flat and a 12 mm shank diameter, compatible with standard Weldon holders and clamping systems that accept cylindrical shanks with flats.

Which standard covers the cutter dimensions and tolerances?
The cutter is manufactured to DIN 844, which governs the geometry and dimensional interchangeability for this series of end mills.
