End mill DIN 844 Type NR – 16 mm HSS‑Co5 with TiCN, Weldon shank (TECWERK)

The End mill DIN 844 Type NR, 16 mm is a short multi-flute cutter in HSS‑Co5 with TiCN coating, designed for robust milling of medium-strength steels and cast iron in production environments

• DIN 844 Type NR short multi-flute design
• 16 mm diameter; 42 mm effective cutting length
• TiCN coating on HSS‑Co5 for extended wear
• Weldon shank with drive flat for secure clamping

High-performance cutting for consistent throughput

Constructed from HSS‑Co5, this tool delivers a balance of toughness and hardness that suits production milling where tool life and chip control are decisive. The TiCN coating reduces adhesive wear and increases surface hardness, allowing higher sustained cutting loads. With a 4‑flute geometry and right‑hand cutting orientation, the cutter produces stable chips and improved surface finish compared with high-helix roughers, especially in short‑overhang operations. Compliance with DIN 844 provides dimensional and performance predictability for repeatable process planning.

Secure clamping for repeatable accuracy

The Weldon shank (TW) with drive flat provides direct torque transmission and minimises slippage in collets and chucks, which is crucial for small‑diameter cutters under intermittent loading. The cylindrical shank and precise shank diameter promote concentricity, reducing runout and enabling consistent part tolerances. The overall length of 92 mm combined with a 42 mm effective cutting length keeps the tool rigid in typical setups, lowering the risk of chatter and permitting predictable cycle times in batch production.

Material suitability that supports mixed workflows

This cutter is specified for machining steels up to approximately 800 N/mm² uncoated and up to 1,000 N/mm² with coating, providing a clear guideline for process limits. The geometry and material pairing make it very well suited to steel and cast iron, while applications involving non‑ferrous metals, special alloys or stainless steel are possible but conditional, depending on cutting data and coolant strategy. The centre‑cutting characteristic allows limited plunging, simplifying pocket entry and reducing the need for pre-drilling in many operations.

Optimised geometry for efficient finishing and stability

A short, multi‑cutter design with a 45° chamfer and a relieved helix profile improves entry behaviour and reduces axial forces during engagement, which benefits finishing passes and fine contour work. The honed relief profile reduces edge chipping and extends usable life in interrupted cuts. For operators seeking a single‑tool solution for finishing and medium‑duty slotting, this cutter combines centre cutting capability with a robust edge treatment to deliver consistent dimensional quality and reduced secondary processing.

FAQ

Which materials is this end mill best suited for?
The end mill (DIN 844 Type NR, 16 mm) from TECWERK is very well suited for steel and cast iron; use in non‑ferrous metals, special alloys and stainless steel is conditional and depends on cutting data and coolant.

Can this cutter perform plunge cutting or drilling into the material?
Yes — the tool’s centre‑cutting geometry permits limited plunge operations; for deep plunges or full‑depth drilling, select specific plunge tools or adjust feeds and speeds accordingly.

What benefits does the TiCN coating provide for production runs?
The TiCN coating increases surface hardness and reduces adhesive wear, which helps maintain edge geometry under higher cutting loads and extends tool life in batch production.

How does the Weldon shank improve setup reliability?
The Weldon TW shank with drive flat ensures secure torque transmission and prevents slippage in the tool holder, improving repeatability and concentricity for consistent part quality.

Is the tool compliant with recognised standards?
The cutter conforms to DIN 844 dimensional and design conventions and is supplied under SKU 2000866446NW, facilitating integration into standardised workflows.
