TECWERK short 4 mm HSS‑Co8 TiCN Weldon end mill, DIN 844 Type N

A TECWERK short 4 mm HSS‑Co8 TiCN Weldon end mill engineered for high-precision milling and plunge work in steel, stainless steel and cast iron applications

• High-performance HSS‑Co8 core
• TiCN coating for extended tool life
• 4‑flute geometry for improved surface finish
• Weldon shank with drive flat

Precision and cut quality with four‑flute geometry

The short four‑flute design delivers a balance between rigidity and cutting engagement, producing a consistently fine surface finish in milled contours. The 4‑flute layout increases axial stability compared with fewer‑flute cutters, which reduces chatter in interrupted cuts; this advantage is particularly relevant when tight tolerances are required. In practice, the geometry supports smooth tool paths on CNC and manual milling machines while maintaining dimensional accuracy across repeating runs.

Heat resistance and wear performance for demanding materials

Manufactured from HSS‑Co8 (high‑speed steel with 8% cobalt), the cutter sustains higher temperatures and improved red hardness compared with standard high‑speed steels. The application of a TiCN coating further increases wear resistance and can extend tool life under elevated thermal loads. Performance guidance: uncoated tooling is suitable up to about 800 N/mm², while the coated variant can be used up to approximately 1000 N/mm², enabling confident machining of tougher steels and persistent stainless grades.

Versatile shank and plunge capability for flexible use

Equipped with a Weldon shank (cylindrical shank with drive flat) and a centre‑cutting geometry, the tool is suitable for axial plunging as well as conventional peripheral milling operations. The drive flat secures positive clamping in collets and holders that accept Weldon flats, reducing slippage during heavy engagement. The centre‑cutting feature enables short plunge cuts without the need for pre‑drilling, enhancing process flexibility in cavity starts and pocketing.

Short overall length for rigidity and repeatability

The compact, short design prioritises rigidity to minimise deflection and vibration in deep or constrained setups. Reduced overhang delivers improved repeatability and surface integrity, which is beneficial when working with stainless steel and cast iron, both listed as very well suited for this cutter. The truncated profile also simplifies toolpath planning for high‑precision pockets and shoulders where chatter or runout would otherwise compromise part quality.

FAQ

What materials is this end mill best suited for?
The TECWERK short 4 mm HSS‑Co8 TiCN Weldon end mill is very well suited for steel, stainless steel and cast iron; non‑ferrous metals and special alloys are conditionally suitable according to the tool specification.

Can this cutter perform plunge cuts?
Yes, the centre‑cutting geometry permits axial plunging; the tool is designed for both plunge starts and conventional peripheral milling.

How does the TiCN coating affect performance?
The TiCN coating increases wear resistance and thermal stability, extending life in demanding operations and allowing machining of materials up to about 1000 N/mm² when coated.

What clamping system is recommended for this tool?
The Weldon shank requires a holder or collet that accepts a drive flat; the drive flat reduces slippage under higher torque and heavy engagement.

Is the tool suitable for high‑temperature steel applications?
With its HSS‑Co8 composition and TiCN coating, the cutter provides improved heat resistance and is appropriate for demanding steel and stainless applications within the stated strength ranges.
