TECWERK Full‑Radius End Mill, 4 mm • Solid Carbide • TiAlN • 2 Flutes (Short)

The TECWERK full‑radius end mill 4 mm is a short, centre‑cutting solid carbide cutter engineered for accurate radius profiling and reliable plunge capability in steels and non‑ferrous alloys

• TiAlN coating for extended tool life
• Solid carbide, fine‑grain body
• Centre‑cutting, 2‑flute design
• Cylindrical shank DIN 6535 HB

High rigidity and lasting tool life for precision machining

Made from solid carbide fine‑grain material and finished with a TiAlN coating, this short radius cutter combines hardness with oxidation resistance for longer productive lifetimes. The compact geometry increases stiffness at the cutting edge, reducing deflection during radius profiling and contouring operations. With a 4 mm diameter and 12 mm effective cutting length, the tool offers a balance between access and rigidity that supports repeatable tolerances in small features and finishing passes.

Plunge capability and broad material compatibility

Thanks to its centre‑cutting geometry and a 2‑flute layout, the cutter permits safe plunge milling as well as conventional side milling. The tool is specified as highly suitable for a wide range of workpiece materials including steel, stainless steel, cast iron, bronze, brass, copper, aluminium with silicon content and abrasive plastics. This makes the cutter well suited to mixed‑batch environments where flexibility across substrate types is required without frequent tool changes.

Geometry and chip control that improve surface quality

A 30° helix and right‑hand cutting orientation promote controlled chip evacuation and smoother surface finish on small radii. The short version reduces overhang, which together with the cylindrical shank DIN 6535 HB and shank tolerance h6 increases concentricity and minimises runout when held in a precision collet. The combination of helix angle and two‑flute design also reduces cutting forces in slotting and light profiling operations, lowering the risk of chatter and improving final component appearance.

Practical applications and handling recommendations

Suitable for finishing, radius machining and plunge operations in toolrooms and production cells, the cutter excels where access and precision matter. Use of a proper collet to match the 6 mm shank diameter and attention to coolant or air blast for chip clearance will extend service life. Inspect the cutting edges for wear before critical runs; the TiAlN coating tolerates elevated temperatures but full‑depth continuous cutting on hard alloys may require adjusted feeds and review of toolpath strategy to maintain optimal tool life.

FAQ

Is this cutter suitable for plunge milling into steel?
Yes. The TECWERK full‑radius end mill is centre‑cutting, which permits plunge operations into steel and similar materials when used with appropriate feeds and toolholders.

Which toolholder is recommended for best concentricity?
A precision collet matching the 6 mm shank diameter with h6 tolerance is recommended to maintain concentricity and reduce runout for the TECWERK cutter.

Can the tool be used for finishing aluminium components?
Yes. The TiAlN coating and two‑flute geometry support finishing of aluminium alloys, including those with silicon content, provided chip evacuation is managed and cutting parameters are adjusted accordingly.

What advantages does the TiAlN coating provide?
The TiAlN coating increases thermal and wear resistance, helping the cutter retain edge stability at higher cutting temperatures and extending service life in demanding production cycles.
