TECWERK HSS‑Co PM ALCRONA short end mill D20 mm (DIN 844, Type N, 4 flutes)

A TECWERK HSS‑Co PM ALCRONA short end mill D20 mm (DIN 844, Type N) engineered for accurate milling of steels, stainless steel and cast iron up to roughly 1000 N/mm² in short‑reach operations

• HSS‑Co PM substrate with ALCRONA coating
• Weldon cylindrical shank with drive flat
• Unevenly spaced flutes for vibration reduction
• Suited to steel and stainless up to 1000 N/mm²

High‑performance substrate and coating for extended durability

The combination of HSS‑Co PM (powder‑metallurgy high‑speed steel with cobalt) and an ALCRONA surface treatment provides a balance of toughness and wear resistance that favours interrupted cuts and moderate feed rates. The steel‑based substrate tolerates higher temperatures and shock loading better than standard HSS, while the coating reduces adhesion and micro‑welding on the cutting edges. This results in longer tool life and more predictable regrinds, improving process economics in short‑to‑medium production runs.

Stable cutting with reduced vibration and improved surface quality

An asymmetric, uneven pitch between the four flutes reduces harmonic excitation during milling, delivering vibration reduction and consequently more consistent surface finish and tool security. The tapered flute root increases local stiffness, which minimises chatter and enables efficient transfer of cutting forces into the workpiece. A centre‑cut geometry allows for limited plunging, expanding the range of applicable machining strategies for pocketing and slotting in constrained setups.

Secure clamping and compact geometry for short‑reach machining

The Weldon shank with drive flat provides positive location in holders and prevents rotation under heavy side loads, ideal for machines with high torque. With Ø20 mm shank and an overall length of 104 mm, the tool is classified as a short DIN 844 Type N cutter; the cutting length 4 mm and effective length 52 mm make it suitable for operations where rigidity is paramount. The right‑hand cutting direction and four‑cut geometry offer a compromise between material removal rate and surface quality for typical workshop applications.

Application range and measurable production benefits

Designed for machining tasks up to approximately 1000 N/mm², the geometry shows very good suitability for steel, stainless steel and cast iron, while non‑ferrous metals and certain special alloys are conditionally suitable. The compact, high‑rigidity design reduces setup time and scrap risk in series production, translating to faster cycle times and lower lifecycle costs per part. For specialised materials or unusual machining strategies, technical consultation is recommended to match feeds, speeds and coolant strategy to the specific process.

FAQ

Can this end mill perform plunge cuts?
The TECWERK short end mill features a centre‑cut geometry that allows limited plunging; where deeper plunges are required, tool and process parameters should be verified before production.

Which materials is the tool best suited for?
The tool is very well suited to steel, stainless steel and cast iron up to approximately 1000 N/mm²; non‑ferrous materials and special alloys are conditionally suitable depending on cutting data.

What clamping system is recommended for secure mounting?
A Weldon holder or equivalent clamping system that mates with a drive flat is recommended to prevent rotation and maintain rigidity under side loads.
