TECWERK HSS-Co PM End Mill D20 mm – 4-flute, ALCRONA-coated, Weldon shank

The TECWERK end mill is a long, centre-cutting milling cutter designed under DIN 844 for precision machining of steels and stainless materials at elevated strength levels.

• HSS-Co PM for high heat and toughness
• ALCRONA coating for extended tool life
• Weldon shank with drive flat for secure clamping
• 4-flute, centre-cutting, right-hand milling cutter

Enhanced cutting performance with powder-metallurgy HSS

Built to DIN 844 standards, this end mill combines HSS-Co PM metallurgy with an ALCRONA surface finish to deliver improved wear resistance and thermal stability during heavy-duty milling. The powder-metallurgy composition increases toughness and hardness retention at elevated temperatures, which helps maintain cutting geometry under load. The ALCRONA coating reduces abrasive wear and supports longer intervals between tool changes, contributing to measurable productivity gains in batch and single-piece production environments.

Secure clamping and stable long-reach machining

A Weldon shank with drive flat and a cylindrical shank profile ensure secure clamping even under high radial loads, while the tool’s geometry provides stiffness for extended reach operations. The tool’s effective length of 89 mm and overall length of 141 mm permit deeper engagement where needed, whereas the relatively short cutting length of 4 mm enables focused axial machining with controlled chip formation. The conical flute root creates an improved rigidity profile, reducing chatter and enhancing surface finish in slotting and peripheral milling tasks.

Broad application range and efficient material removal

Designed for machining materials up to approximately 1400 N/mm², this cutter is very well suited to machining steel, stainless steel and cast iron, with conditional suitability for certain non-ferrous alloys and specialty materials. The 4-flute layout balances feed rates and chip evacuation for high metal removal rates, and the centre-cutting geometry permits limited plunge milling where required. The 45° protective chamfer on the cutting edges reduces edge chipping and extends usable life, making the cutter a practical choice for production and repair workshops seeking dependable cutting performance.

FAQ

What materials is this cutter best suited for?
The TECWERK HSS-Co PM end mill (SKU 2000866077NW) is very well suited for steel, stainless steel and cast iron and is rated for materials up to approximately 1400 N/mm².

Can the tool be used for plunge milling?
Yes, the cutter is centre-cutting, which allows limited plunge milling in addition to conventional peripheral and slotting operations.

How does the ALCRONA coating benefit production runs?
The ALCRONA coating increases wear resistance and reduces abrasive degradation, resulting in longer tool life and fewer tool changes during production.

What clamping system is required for safe operation?
A secure toolholder compatible with a Weldon-style drive flat is recommended to ensure the Weldon shank achieves optimal clamping force and torque transmission.

Is this cutter suitable for high-speed machining?
The HSS-Co PM substrate offers improved thermal stability and toughness; however, machining parameters should be set according to workpiece material and machine capabilities for high-speed applications.
