TECWERK End mill DIN 844 Type NR, Ø8 mm — HSS‑Co5, TiCN, Weldon shank

The TECWERK End mill DIN 844 Type NR is a short, multi‑flute cutter designed for accurate machining of steel and cast iron, offering centre cutting and high clamping stability for workshop and light industrial use

• DIN 844 short multi‑flute design
• HSS‑Co5 with TiCN coating for wear resistance
• Weldon shank with drive flat for secure clamping

Predictable performance through standardised geometry

Built to DIN 844, this short multi‑flute end mill delivers consistent cutting geometry that reduces process variation and simplifies tool selection. The combination of a HSS‑Co5 substrate and a TiCN coating provides a balance between toughness and surface hardness, enabling reliable edge retention under interrupted cuts. With a Ø8 mm cutter diameter and an effective length of 25 mm, the tool offers predictable engagement volumes, which supports stable cycle times and consistent part quality in serial production.

Longer life and improved surface finish with the right coating

The TiCN (titanium carbonitride) layer increases surface hardness and lowers friction, which reduces built‑up edge and improves finish on ferrous materials. The cobalt content in HSS‑Co5 improves red hardness and thermal resistance compared with standard HSS, allowing higher machining temperatures before hardness loss. Together these materials extend tool life and maintain dimensional accuracy over longer runs, making the cutter a cost‑effective choice for repetitive milling tasks where component quality matters.

Secure clamping and vibration‑resistant machining

A Weldon shank with drive flat and a 10 mm shank diameter provides a positive location in holders, reducing slippage and runout at the toolholder interface. The tool’s overall length of 69 mm and short design increase stiffness, while the 3‑flute geometry balances chip evacuation and cutting edge strength. These features reduce chatter and support reproducible toolpaths, which is particularly beneficial when machining prismatic parts or when tight tolerances are required.

Clear guidance on applications and material suitability

This short end mill is optimised for materials of low to medium strength: it is very well suited to steel and cast iron, while non‑ferrous and special alloys are conditionally machinable with adapted cutting data. The geometry includes a centre cutting capability and a 45° protective chamfer, enabling limited plunge cuts and reliable entry into workpieces. For steels up to 800 N/mm² with an uncoated tool and up to 1000 N/mm² when coated, the tool offers dependable performance; adjust feeds and speeds according to machine rigidity and workholding for best results.

FAQ

What materials is this end mill best suited to?
The TECWERK end mill (SKU 2000866469NW) is very well suited to steel and cast iron; non‑ferrous metals, stainless steel and special alloys are conditionally machinable with adapted cutting data.

Can this cutter be used for plunge milling?
Yes. Because the cutter is centre cutting, the tool allows limited plunge operations; use conservative feeds when plunging to preserve edge life.

How does the Weldon shank affect clamping?
The Weldon shank with drive flat and a 10 mm shank diameter gives secure clamping and reduced slippage, improving runout stability for the TECWERK end mill (2000866469NW).

What performance benefit does the TiCN coating provide?
The TiCN coating increases surface hardness and reduces friction, which lowers built‑up edge formation and improves surface finish and tool life under elevated temperatures.

Which standard and geometry does the tool conform to?
The cutter conforms to DIN 844 and features a short multi‑flute Type NR geometry with a 45° protective chamfer, a relieved flute profile and right‑hand cutting.
