TECWERK End Mill DIN 844 Type NR — 14 mm, HSS‑Co5, TiCN, Weldon TW

TECWERK End Mill DIN 844 Type NR engineered for short multi‑flute milling in steels and cast iron, ideal for medium‑duty production and maintenance work where secure clamping is required

HSS‑Co5 base material for durability TiCN coating extends tool life Four flutes for efficient chip evacuation Weldon shank with drive flat for secure clamping

Consistent, measurable cutting performance for production environments

The TECWERK end mill follows DIN 844 standards and delivers a repeatable machining outcome thanks to its 14 mm diameter and 36 mm effective cutting length. The short multi‑flute geometry produces stable radial forces, reducing chatter during interrupted or light finishing cuts and enabling consistent dimensional accuracy in serial work. Measurable suitability for materials is specified: the tool is designed for work on steel and cast iron, providing defined operational limits that support planning of feeds and speeds in a production schedule.

Extended tool life through material and coating technology

Made from HSS‑Co5, the substrate offers enhanced hot‑hardness compared with conventional high‑speed steels, while the TiCN coating reduces adhesive wear and improves surface finish on the workpiece. This combination extends tool life and increases time between regrinds, which lowers process costs and downtime. The protective 45° chamfer and centre‑cutting geometry aid in plunge starts and reduce edge chipping, making the cutter well suited to interrupted cuts and mixed operation regimes.

Secure clamping and practical geometry for workshop use

A Weldon shank with a drive flat (Weldon TW) ensures positive torque transmission in standard milling holders and arbors, reducing slip under higher torque. The four flutes improve chip control and allow a balance between surface finish and material removal rate; chip evacuation remains efficient when machining medium‑strength steels up to 800 N/mm² with an uncoated tool and up to 1000 N/mm² when the coating is engaged. The short, relieved core profile enhances rigidity, so the cutter maintains form tolerance over extended runs.

Recommended applications and handling notes

The cutter is particularly effective for finishing and semi‑finishing operations on steel and cast iron, and it can be used conditionally on aluminium and certain non‑ferrous alloys when appropriate cutting data are applied. For stainless steels and special alloys, a cautious feed strategy and suitable coolant are advised due to their work‑hardening tendencies. The cylindrical shank with drive flat supports quick tool changes in standard toolholders; ensure correct clamping length and coolant delivery to maximise the service life of the tool.

FAQ

What materials are best machined with this end mill?
The TECWERK end mill is very well suited to steel and cast iron; non‑ferrous metals and special alloys are workable with adapted cutting data.

Is the cutter suitable for plunge milling or only peripheral milling?
The centre‑cutting geometry allows plunge starts as well as peripheral milling, making the tool versatile for slotting and ramping operations.

How does the TiCN coating affect cutting performance?
The TiCN coating reduces adhesive wear and increases edge strength, which prolongs the tool life of the HSS‑Co5 substrate under typical workshop conditions.

What clamping system is recommended for this tool?
Use a standard Weldon holder or collet chuck that accommodates a Weldon TW shank with drive flat to ensure secure torque transmission.

Which standard does this tool comply with and what does that mean for use?
Compliance with DIN 844 indicates standardised geometry and dimensions, simplifying tool selection and replacement in industrial settings.
