TECWERK HSS‑Co PM End Mill DIN 844 — D 12 mm, ALCRONA‑coated, Long, 4‑Flute

The TECWERK HSS‑Co PM end mill DIN 844 HR D12 is a long, four‑flute, right‑hand centre‑cutting cutter designed for robust milling of steels and stainless materials in demanding workshop and production environments.

• HSS‑Co PM for elevated wear resistance
• ALCRONA coating for improved heat protection
• Weldon shank for secure toolholding
• Centre‑cutting for limited plunge operations

Consistent performance through advanced material and coating

The combination of HSS‑Co PM substrate and ALCRONA coating delivers a dependable balance between toughness and surface hardness. The powder‑metallurgy cobalt steel offers improved red‑hardness and shock resistance compared with conventional high‑speed steels, while the coating reduces friction and thermal loading. This results in longer tool life and steadier cutting behaviour in interrupted cuts, which is especially relevant for series work and shop floor reliance.

Increased rigidity and secure clamping for stable machining

Built to the DIN 844 long‑shank profile with a Weldon shank, the cutter provides a reliable clamping interface and reduced slippage in holders with flats. The 4‑flute geometry combines axial stiffness with improved surface finish on side milling, and the tapered flute root contributes to improved tool stiffness under load. The centre‑cutting design and 45° protection chamfer permit limited plunge operations and protect the cutting edges during engagement, reducing the need for frequent tool changes.

Clear suitability for demanding materials and tensile limits

Designed for milling workpieces with tensile strengths up to approximately 1400 N/mm², this tool is very well suited for steel, stainless steel and cast materials, while non‑ferrous and special alloys are conditionally machinable. The material‑suitability indications mean fewer trial cuts and a faster determination of the right cutting data, supporting more efficient process planning in mixed production runs.

Practical dimensions and workplace benefits

With a 12 mm diameter, 110 mm overall length and an effective length of 63 mm, the long version is intended for operations where reach is required without compromising stability. The modest cutting length helps concentrate cutting forces near the tool tip, which combined with the robust substrate and coating delivers repeatable results. The cylindrical shank with drive flat ensures positive torque transmission for aggressive feeds while maintaining concentricity in standard toolholders.

FAQ

Is this tool suitable for plunge milling?
The TECWERK HSS‑Co PM end mill features a centre‑cutting geometry that allows limited plunge operations; it is primarily optimised for peripheral and shoulder milling.

Which materials show the best performance with this cutter?
Best results are achieved on steel and stainless steel; the ALCRONA coating and HSS‑Co PM substrate make the cutter particularly resilient when machining these materials.

What clamping interface does the tool require?
The Weldon shank with drive flat is designed for secure clamping in holders that accept Weldon shanks, ensuring reliable torque transmission.

Can the long version be used for deep pocketing?
Yes, the long‑shank configuration and 63 mm effective length permit deeper reach, but attention to deflection and appropriate cutting data is recommended.

What advantage does the ALCRONA coating provide?
The ALCRONA coating reduces friction and thermal load, increasing tool life and maintaining cutting edge integrity under higher cutting temperatures.
