End mill DIN 844 Type HR, Ø12 mm, HSS-Co PM, ALCRONA-coated, Weldon shank — TECWERK

A End mill DIN 844 Type HR designed as a long, four-flute, centre-cutting tool for reliable milling of steels, stainless steels and cast iron up to approx. 1400 N/mm²

• HSS-Co PM for high abrasion resistance
• ALCRONA coating for extended tool life
• Four-flute, centre-cutting geometry
• Weldon shank with drive flat for secure clamping

High-strength milling with consistent productivity

Constructed from HSS-Co PM (powder-metallurgical high-speed steel with cobalt), this long, four-flute cutter delivers a balance of toughness and wear resistance that is suited to demanding shop-floor work. The geometry is optimised for materials with tensile strength up to ~1400 N/mm², which enables fewer tool changes and predictable cycle times when machining medium- to high-strength steels. The centre-cutting design allows plunge operations, while the four cutting edges support higher feed per tooth and a more efficient material removal rate, resulting in improved throughput for serial and single-piece production alike.

Longer life and surface quality through coating and geometry

The ALCRONA coating reduces abrasive wear and heat transfer at the cutting edge, which extends the tool life under elevated temperatures and intermittent cut conditions. Combined with a 45° protective chamfer at the cutting face and a tapered flute root that increases stiffness, the tool produces a more consistent surface finish and reduces the occurrence of build-up on the flutes. For workshops seeking reliable repeatability, these features translate into fewer interruptions, lower rework rates and a steadier first-pass quality.

Secure clamping and improved rigidity for repeatable accuracy

A Weldon shank with drive flat ensures secure clamping in standard holders, eliminating slippage during interrupted cuts or heavy roughing. The conically reinforced flute base improves bending resistance and reduces vibration, which benefits dimensional accuracy and tool life in long-reach operations. Because runout and chatter are minimised, tolerances can be maintained with greater confidence, especially in applications where long-length cutters are required to reach deep features or clear fixtures.

Material suitability and typical applications explained

This tool is very well suited for steel, stainless steel (inox) and cast iron, while performance in non-ferrous and certain special alloys is conditional depending on machining strategy and cutting data. The right-hand cutting direction and centre-cutting capability permit both conventional milling and plunge cuts, making the cutter appropriate for slotting, pocketing and profile work in fabrication, mould-and-die pre-machining and maintenance machining tasks. When paired with appropriate feeds and coolant strategy, the cutter supports efficient machining of challenging components without excessive thermal or mechanical wear.

FAQ

What materials can be machined with this end mill?
The TECWERK end mill is very well suited for steel, stainless steel (inox) and cast iron; performance in non-ferrous metals and certain special alloys is conditional and depends on cutting data and machining strategy.

Can this cutter be used for plunge milling?
Yes. The centre-cutting geometry allows plunge operations so the long four-flute cutter can be used for both slotting and plunge milling where access and tool length require it.

How does the ALCRONA coating benefit workshop productivity?
The ALCRONA coating reduces abrasive wear and heat at the cutting edge, which extends tool life and supports more consistent surface finish, lowering downtime for tool changes and rework.
