TECWERK HSS-Co PM End Mill DIN 844 — 20 mm, 4-flute, ALCRONA-coated

TECWERK HSS-Co PM end mill for short, high-rigidity milling in steels and stainless steels

• HSS-Co PM for high wear resistance
• ALCRONA coating for extended tool life
• 4-flute geometry for fine surface finish
• Weldon shank for secure clamping

Exceptional rigidity for heavy-duty milling and long tool life

This short cutter is built from HSS-Co PM (powder-metallurgy high-speed steel), a microstructure tailored for elevated toughness and wear resistance. The tool’s tapered flute root increases cross-section where it matters, improving tool rigidity and reducing vibration during interrupted or heavy cuts. The result is a consistently improved part finish and fewer rejections when machining materials with high tensile strength up to 1400 N/mm². For procurement and planning, this specification provides a clear basis for matching machine capabilities to the cutter’s performance.

Accurate cutting and controlled chip flow for better surface quality

The 4-flute layout combined with a centre-cutting geometry enables axial plunging and steady radial engagement, producing a finer surface finish than coarse-fluted cutters. The short design and 45° chamfer on the cutting edge protect the tool margin and support initial entry, while the ALCRONA coating reduces friction and heat build-up, promoting reliable chip evacuation. These features together lower the risk of built-up edge on stainless and alloyed steels, so less post-processing is required and cycle times can be shortened.

Broad material suitability for versatile workshop use

Material compatibility has been optimised: steel, stainless steel, and cast iron are rated very good for this cutter, while non-ferrous metals and advanced special alloys are conditionally suitable. The designation to machine materials up to 1400 N/mm² makes the tool suitable for demanding repair, prototype and small-batch production tasks where both strength and surface integrity matter. The centre-cutting capability further expands application flexibility by permitting axial entry for pockets and blind features.

Secure clamping and practical handling for industrial workflows

A cylindrical shank with a Weldon shank (driving flat) ensures positive clamping in toolholders and minimises slippage under torque; the short length reduces overhang and improves stability in standard holders. This configuration simplifies tool change procedures and reduces set-up time while preserving concentricity. The combined benefits of coating, short geometry and shank design help maintain cutting performance over multiple components, supporting an efficient production flow and lower overall tooling consumption.

FAQ

What materials is this cutter best suited for? This TECWERK HSS-Co PM end mill is optimised for steel, stainless steel and cast iron, with conditional suitability for non-ferrous metals and specialised alloys.

Can the cutter plunge axially or is it limited to peripheral milling? The cutter has a centre-cutting geometry so axial plunging is possible; the short design further improves stability during plunge operations.

How does the ALCRONA coating benefit machining performance? The ALCRONA coating reduces friction and heat at the cutting edge, improving wear resistance and extending tool life during continuous or interrupted cuts.

What does the Weldon shank provide in a production setting? The Weldon shank (driving flat) ensures secure clamping and minimal slippage under torque, supporting repeatable concentricity in industrial toolholders.

Is this tool suitable for high-strength steels up to 1400 N/mm²? Yes, the cutter is specified for machining materials up to 1400 N/mm², making it appropriate for many high-strength steel applications.
