20mm Solid Carbide End Mill DIN 844 NR 52mm Cutting Length HSS-Co5 45° Chamfer Weldon Shank - TECWERK

Take advantage of high‑alloy HSS‑Co5 cutting performance combined with a Weldon shank for stable clamping and consistent results when milling steel and cast iron; order the cutter directly via Metav Werkzeuge or ask our consultants if needed.

End mill DIN 844 Type NR, 20 mm, HSS‑Co5, Weldon TW (TECWERK)

The end mill DIN 844 Type NR (20 mm, HSS‑Co5) is a short multi‑flute cutter designed for precision milling of steels and cast iron in workshop and industrial environments

• HSS‑Co5 for high wear resistance
• Weldon shank with drive flat
• Centre‑cutting, right‑hand helix
• Suited for steel and cast iron

Consistent cutting performance for demanding components

The tool is manufactured from HSS‑Co5, a high‑speed steel with cobalt alloying that increases red hardness and wear resistance. This composition ensures steady cutting performance when machining tougher materials, enabling the cutter to process workpieces with tensile strengths of up to 800 N/mm² with an uncoated tool and up to 1000 N/mm² when used with a suitable coating. The result is predictable tool life and repeatable surface quality, which supports tighter process planning and reduced scrap rates.

Secure clamping and precise chip control for reliable processes

A Weldon shank with a drive flat provides positive torque transmission and secure toolholding in conventional toolholders, reducing the risk of slippage under load. The short, multi‑flute geometry combined with a centre‑cutting design allows limited plunging and consistent entry behaviour, while the 45° protective chamfer and the relieved cord profile help to control chip flow and reduce edge loading. Together these features promote dimensional stability and a cleaner finish on interrupted or continuous cuts.

Designed to increase workshop throughput and ease of use

The compact design improves rigidity compared with longer tools, lowering vibration and improving surface integrity on each pass. The cutter is right‑hand cutting, optimised for common machining setups, and its construction makes regrinding and maintenance straightforward for experienced toolrooms. Conditional suitability for non‑ferrous metals gives flexibility across job types, while the strong performance on steel and cast iron makes the tool a practical choice for mixed production environments.

Confidence through supply and application knowledge

Metav’s position as a precision partner supports reliable supply and technical clarity: the tool is supplied under the TECWERK designation and aligns with the mechanical expectations of DIN 844 Type NR parts. The combination of documented material suitability and standardised shank form means the cutter can be integrated into existing workflows with minimal adaptation. Metav’s extensive product range and customer experience back up the product’s role in everyday workshop productivity.

FAQ

What materials is the end mill suitable for?
The TECWERK end mill DIN 844 Type NR is very well suited for steel and cast iron; non‑ferrous metals are only conditionally suitable according to the supplied specifications.

Can the cutter perform plunge operations?
Yes, the cutter is centre‑cutting, which permits limited plunging and reliable entry behaviour for pocketing and interrupted cuts.

How is the tool held in the spindle?
The cutter uses a Weldon shank (Weldon TW) with a drive flat to ensure secure clamping and positive torque transmission in compatible holders.

What are the key dimensions of the cutter?
Diameter is 20 mm and cutting length (Einsatz‑L) is 52 mm, as specified in the product designation.

Is the tool supplied with a coating?
The product data lists the tool material as HSS‑Co5 and describes performance values for uncoated and coated conditions, but the standard supply is uncoated in the provided description.
