TECWERK End Mill DIN 844 — Ø 8 mm, HSS‑Co PM, ALCRONA‑coated, Weldon, 4 flutes, long

The TECWERK end mill provides a long‑reach, centre‑cutting solution for demanding milling of steel, stainless steel and cast iron in production and toolroom environments.

• HSS‑Co PM base material with ALCRONA coating
• Four‑flute, centre‑cutting geometry for versatile milling
• Long reach with Weldon cylindrical shank for stability
• Optimised flute design for vibration reduction

Deliver consistent material removal and extended tool life

This long‑reach cutter is built from HSS‑Co PM, a powder‑metallurgy cobalt high‑speed steel that delivers improved toughness and wear resistance compared with conventional HSS. The ALCRONA coating adds a tribological barrier, reducing built‑up edge and extending tool life in intermittent or continuous cuts. With a Ø 8 mm cutting diameter and four flutes, the tool balances chip evacuation and surface finish: the multiple cutting edges reduce feed per tooth while maintaining material removal rates. The centre‑cutting geometry permits limited plunge milling and safe ramping into the workpiece, which broadens application options beyond purely peripheral passes.

Improved stability and vibration control for better surface quality

Designed for demanding setups, the cutter combines a Weldon shank with a cylindrical shaft featuring a drive flat for secure clamping in tool holders. The overall length 88 mm and effective length 44 mm give genuine long‑reach capability while retaining rigidity where it matters. Vibration is reduced by an unevenly divided flute pitch and a conical flute root that increases stiffness along the cutting edge—this translates into steadier cutting, fewer chatter marks and a more uniform finish. The short cutting length 4 mm and ground relief (7.5 mm relief) concentrate cutting forces where they are most effective, helping to protect the tool and the machine spindle in cantilevered setups.

Clear application window and machining guidance

The geometry and material combination make this cutter very well suited to steel, stainless steel and cast iron, with conditional suitability for non‑ferrous metals and special alloys. It is optimised for workpiece strengths of up to approximately 1000 N/mm², so it performs reliably in a broad range of industrial tasks from maintenance milling to component finishing. As a right‑hand cutting tool with four flutes and a centre‑cutting tip, it is a practical choice for slotting, pocketing and finishing operations where accessibility and surface quality are priorities. For secure assembly use holders compatible with a 10 mm shank diameter and a Weldon drive flat.

FAQ

What materials is this end mill suitable for?
The TECWERK end mill is very well suited for steel, stainless steel and cast iron; it is conditionally suitable for non‑ferrous metals and special alloys.

Can this cutter perform plunge operations?
Yes. The centre‑cutting geometry allows for limited plunge milling and safe ramping into the workpiece, expanding its use beyond peripheral milling.

What does the Weldon shank mean for clamping?
A Weldon cylindrical shank provides a drive flat for secure clamping; the 10 mm shank diameter ensures compatibility with standard Weldon holders and reduces slippage during heavy cuts.

How does the ALCRONA coating affect tool life?
The ALCRONA coating improves wear resistance and reduces adhesion of workpiece material, which extends cutting life and helps maintain surface finish during interrupted cuts.

Why choose a powder‑metallurgy HSS‑Co grade?
The HSS‑Co PM substrate combines enhanced toughness and wear resistance, giving better edge retention under tougher milling conditions compared with conventional HSS.
