TECWERK End Mill DIN 844 Type HR – 18 mm, HSS‑Co5, TiCN coating

The TECWERK end mill is a short, 4‑flute, high‑toughness cutter designed for precision milling of steels and castings, offering a secure Weldon shank and a TiCN finish for extended tool life.

• TiCN coating for extended tool life
• HSS‑Co5 core for high toughness
• Short 4‑flute profile for stable machining
• Weldon shank with drive flat, 16 mm shank

High performance material pairing for consistent results

The combination of HSS‑Co5 substrate and a TiCN surface finish provides a balance of toughness and wear resistance that suits intermittent and continuous milling alike. The cutter conforms to DIN 844 and features a centre‑cutting geometry, enabling safe entry into material without pre‑drilling in many applications. With a 4‑flute arrangement and a fine honed cutting profile, this short‑length design reduces deflection and helps maintain dimensional accuracy when machining components made from medium‑strength steels and cast iron.

Short profile and shank design that improve process stability

A reduced overhang and a 42 mm effective length keep the cutter rigid under load, which benefits surface finish and tool life in repetitive operations. The 18 mm diameter combined with the 16 mm Weldon shank and drive flat ensures reliable clamping torque transmission in rigid toolholders. The right‑hand cut and modest cutting length are configured for typical milling strategies where stability and repeatability take priority, making the tool suitable for slotting, side milling and light shoulder milling in workshop and production settings.

Coating and cutting capacity explained in practical terms

The TiCN coating increases surface hardness and reduces built‑up edge compared with uncoated steels, which raises the allowable strength of the workpiece from approximately 800 N/mm² with an uncoated tool to about 1,200 N/mm² when using the coated cutter. In practice, this means longer intervals between tool changes and fewer interruptions in batch runs. The cobalt alloy matrix of the substrate contributes impact resistance and thermal stability, supporting consistent performance under temperate cutting regimes.

Application scope and workshop advantages

This short Type HR cutter excels when machining steel and cast iron, where it is rated as very well suited; it is conditionally suitable for non‑ferrous metals, stainless steels and special alloys. The compact geometry helps reduce chatter on smaller machines and in manual milling fixtures, while the 45° protective chamfer and fine honed edge profile protect the cutting edge during engagement. For shops seeking to standardise tooling across production cells, this cutter offers a pragmatic compromise between robustness and precision.

FAQ

What workpiece materials is this cutter best suited for?
The TECWERK end mill (SKU 2000866518NW) is very well suited for steel and cast iron; it is conditionally suitable for non‑ferrous metals, stainless steels and special alloys.

Does the TiCN coating allow machining of harder steels?
Yes, the TiCN finish on this HSS‑Co5 cutter increases wear resistance and allows machining of materials up to roughly 1,200 N/mm² under appropriate conditions compared with about 800 N/mm² for an uncoated tool.

Is the cutter centre‑cutting and suitable for plunge operations?
The tool features a centre‑cutting geometry, which enables plunging in many applications, though suitability will depend on machine rigidity and cutting parameters.

What shank system is used and how is it clamped?
The cutter uses a Weldon shank with a drive flat (16 mm), providing secure torque transmission in standard Weldon‑style holders.

How does the short profile affect machining performance?
A short profile increases rigidity and reduces deflection, improving dimensional accuracy and finish in milling tasks where stability and repeatability are priorities.
