TECWERK end mill DIN 844 Type NR – 12 mm, HSS‑Co5, TiCN, Weldon shank

The TECWERK end mill DIN 844 Type NR is a short, multi‑flute cutter for precise milling in steels and cast iron, designed for robust performance in industrial and workshop environments.

• DIN 844 short multi‑flute design
• TiCN coating for improved wear resistance
• 4 flutes for controlled chip formation
• Weldon shank with drive flat for secure clamping

High performance and extended tool life for steel and cast iron

The cutter combines a HSS‑Co5 substrate with a TiCN surface to raise hot hardness and abrasion resistance, resulting in noticeably longer service intervals compared with uncoated high‑speed steels. According to the tool data, the geometry is optimised for machining ferrous materials: very good suitability for steel and cast iron, with the coated tool extending application to higher tensile strengths. This balance of substrate and coating reduces flank wear and keeps component tolerances stable over longer production runs.

Precise geometry and efficient chip control for consistent finishes

A 4‑flute configuration and a short, multi‑cutter profile deliver a conservative axial engagement with improved surface quality and steady chip evacuation in interrupted or continuous cuts. The cutter features a centre cut and a 45° protection chamfer that support plunge and ramping operations, while the relieved helical profile reduces rubbing and heat build‑up. Together these geometry choices produce reproducible results on components requiring tight dimensional control.

Secure clamping and standard compliance for shop reliability

The Weldon shank with drive flat and the compliance with DIN 844 ensure straightforward integration into common tool holders and repeatable concentricity at the spindle. Dimensional data such as the 12 mm diameter, an effective length of 36 mm and an overall length of 83 mm provide a compact tool that reduces overhang and improves stability in small to medium machining centres. Right‑hand cutting and the short cutting length help to keep spindle loads predictable, reducing the need for frequent tool changes and supporting a steady production flow.

FAQ

What materials is this end mill best suited for?
The TECWERK end mill with HSS‑Co5 substrate and TiCN coating is very well suited for steel and cast iron; it is conditionally suitable for non‑ferrous metals and special alloys depending on cutting data.

How does the TiCN coating influence performance?
A TiCN coating increases surface hardness and wear resistance, allowing the cutter to handle higher contact temperatures and to maintain cutting edges longer than an uncoated tool.

What are the key dimensions to consider for fixture selection?
Relevant dimensions are 12 mm diameter, 36 mm effective length and 83 mm overall length; the Weldon shank ensures secure clamping in standard holders.

Is the cutter suitable for plunge or ramp milling?
Yes, the centre‑cut geometry and short multi‑flute profile permit limited plunge and ramp operations while maintaining good surface finish and stability.

Does compliance with DIN 844 affect compatibility with existing holders?
Compliance with DIN 844 ensures the tool adheres to a recognised profile and dimensional standard, aiding compatibility with commonly used holders and tool systems.
