TECWERK HSS‑Co8 DIN 844 Type N 4 mm — short 4‑flute milling cutter with Weldon shank

The TECWERK HSS‑Co8 DIN 844 Type N 4 mm short milling cutter is a right‑hand, centre‑cut 4‑flute tool designed for accurate face and side milling in low to medium strength materials, especially steel and cast iron

• HSS‑Co8 high‑alloy construction
• Four‑flute, centre‑cut geometry
• Weldon shank with drive flat
• Short 55 mm overall length for rigidity
• Very good for steel and cast iron

Consistent productivity through alloy and edge geometry

The combination of HSS‑Co8 material and a 4‑flute design delivers a balance of toughness and wear resistance that suits repetitive production tasks. The cobalt‑alloy high‑speed steel improves red‑hardness and edge stability, which translates into longer intervals between regrinds and fewer tool changes. Specified to DIN 844, the geometry ensures predictable cutting behaviour and repeatable results in batch production, so machining cycles stay efficient and downtimes are reduced. This supports a measurable increase in throughput for small parts and finishing operations.

Precision and rigidity in compact setups

A short overall length of 55 mm combined with a shank diameter of 6 mm and a Weldon shank with drive flat reduces cantilever and improves clamping security, which lowers radial runout and enhances surface finish. The cutting length 4 mm and effective length 11 mm are optimised for shallow passes and confined toolpaths where stability is critical. In practice, the compact form factor allows reliable performance on small milling machines, toolholders with limited projection and fixtures that demand high stiffness, making it a practical choice for accurate slotting and profiling.

Material suitability explained for informed machining

The tool is engineered for materials up to approximately 800 N/mm² in strength with the uncoated cutter and can extend capability to around 1000 N/mm² if a suitable coating is applied. It is rated very good for steel and cast iron, while performance on non‑ferrous alloys and stainless steel is conditional and depends on cutting parameters. The centre‑cut feature permits limited axial plunging without pre‑drilling, offering flexibility for interrupted cuts and pocketing in short‑reach applications. Understanding these limits helps select correct feeds and speeds and avoid premature wear.

Easy integration, predictable maintenance, trusted supply

Conformity to DIN 844 and the standard Weldon clamping interface ensure straightforward integration into existing toolholding systems. The straightforward geometry simplifies regrinding and inspection routines, while the robust HSS‑Co base material tolerates typical workshop reconditioning. For buyers, sourcing from an established supplier reduces uncertainty: Metav provides a quality filter for the European market and a broad range of compatible tooling, enabling a consolidated supply chain and reliable stock availability — factors that support uninterrupted production.

FAQ

What applications is this 4 mm TECWERK milling cutter best suited for? This TECWERK HSS‑Co8 short 4‑flute milling cutter excels at face and side milling, small slotting and finishing in steel and cast iron, particularly where a compact, rigid setup is available.

Can the tool be used for plunging operations? The centre‑cut geometry allows limited axial plunging without pre‑drilling; for deeper or continuous plunge work with the TECWERK cutter, assess cutting parameters and machine rigidity first.

Is the cutter suitable for stainless steel or non‑ferrous metals? Performance on stainless steel and non‑ferrous alloys is conditional; the TECWERK cutter can be used with adapted feeds, speeds and, where appropriate, a suitable coating to improve performance.

How does the Weldon shank benefit clamping and runout? The Weldon shank with drive flat secures the tool in the holder, improving clamping stability and reducing radial runout for more consistent surface finishes when using the TECWERK milling cutter.
