End mill DIN 844 Type NR — D 12 mm, 36 mm cutting length, HSS‑Co5 with TiCN, Weldon shank (TECWERK)

The End mill DIN 844 Type NR D.12mm Einsatz‑L.36mm HSS‑Co5 TiCN Weldon TW is a short, multi‑flute cutter engineered for precision milling of cast components and medium‑strength steels in workshop and light industrial environments.

• HSS‑Co5 material with TiCN coating
• Conforms to DIN 844 Type NR
• Weldon shank with drive flat
• 45° protective chamfer and centre‑cut

Reliable machining for cast components and medium‑strength steels

Built from HSS‑Co5, this cutter delivers high wear resistance and thermal stability compared with standard high‑speed steel. The combination of the TiCN coating and cobalt alloy core raises the usable cutting range: uncoated tools are suitable for materials up to approximately 800 N/mm², while the coated variant extends capability to around 1000 N/mm². This translates into consistent surface quality and fewer tool changes in serial work, providing measurable efficiency gains on cast iron and steels with low to medium tensile strength.

Stable clamping and reduced chatter from the shank design

The Weldon shank with a dedicated drive flat ensures a secure seat in the toolholder, reducing micro‑slip and vibration during heavy cuts. The short design and multi‑flute geometry promote higher feed rates and smoother chip evacuation in interrupted cuts. Because the cutter features a centre‑cut, it permits restrained plunge operations where required, increasing setup flexibility without compromising stability or finish.

Coating and material choice that extend service intervals

The TiCN layer offers improved hardness and lower friction at the cutting edge, which reduces built‑up edge and adhesive wear when machining tougher grades. Coupled with the cobalt‑alloy HSS base, the tool resists softening at elevated temperatures and sustains sharper cutting edges for longer. These characteristics deliver lower life‑cycle costs through longer tool life and fewer replacement cycles, especially when processing abrasive cast materials.

Compatible standards and workshop benefits

Manufactured to DIN 844 Type NR, this end mill matches common tooling standards, simplifying replacement and inventory management across mixed fleets of machines. The tool is very well suited for steel and cast iron, while performance for non‑ferrous metals, stainless steels and special alloys is described as conditional; this makes it ideal for shops focused on cast and general steel work. The short, protected cutting edge with a 45° chamfer also reduces accidental damage during handling and storage, preserving cutting geometry until use.

FAQ

Is this cutter suitable for plunge milling?
The centre‑cut geometry allows restrained plunge operations; the cutter supports limited plunge milling while maintaining edge stability.

What advantages does the TiCN coating provide?
The TiCN coating on this end mill reduces friction and adhesive wear, helping to extend tool life and improve surface finish on demanding materials.

Which materials are best processed with this cutter?
The tool is very well suited to steel and cast iron; performance on non‑ferrous metals, special alloys and stainless steels is conditional, depending on cutting parameters.

Does the Weldon shank improve clamping security?
Yes, the Weldon shank with a drive flat provides a secure mechanical interface with the toolholder, reducing slippage and vibration during machining.

What standard does the cutter conform to and why does that matter?
Compliance with DIN 844 Type NR ensures interchangeability with standard holders and predictable cutting geometry for workshop inventory planning.
