TECWERK End Mill DIN 844 Type HR — Ø16 mm, HSS‑Co PM, ALCRONA‑coated, 4‑flute, long, Weldon shank

TECWERK End Mill DIN 844 Type HR — a long, centre‑cutting milling tool engineered for demanding operations in stainless steel and high‑strength steels, offering secure Weldon clamping and improved stiffness for stable deep machining.

• HSS‑Co PM with ALCRONA coating
• 4‑flute long design for deep milling
• Weldon shank with drive flat
• Centre cutting for plunge capability

Stable long‑reach milling that reduces chatter and improves surface quality

The long version of this DIN 844 Type HR cutter combines a 123 mm overall length with an effective reach of 73 mm to permit access into deeper features while maintaining rigidity. The tool’s tapered flute root increases bending resistance, which reduces vibration and delivers a more consistent surface finish during interrupted cuts. For workshops facing confined geometries, the extended reach translates into fewer tool changes and shorter set‑up times, improving productivity on longer workpieces.

Material and coating engineered for longer life in tough alloys

Manufactured from powder‑metallurgy cobalt high‑speed steel (HSS‑Co PM) and finished with an ALCRONA coating, the cutter offers enhanced wear resistance at elevated cutting temperatures. The combination extends tool life when machining stainless and high‑strength steels up to approx. 1400 N/mm² tensile strength. This pairing balances toughness and hardness: toughness helps resist chipping in interrupted cuts, while the coating lowers friction to preserve cutting edges, resulting in fewer tool replacements and steadier cycle times.

Secure clamping and centre‑cutting capability for versatile use

A Weldon shank with drive flat ensures reliable torque transmission in collet and chuck systems, reducing the risk of slippage under heavy axial loads. The centre‑cutting geometry permits controlled plunge milling, enabling pocketing and entry operations without pre‑drilling. With four flutes, the cutter achieves a compromise between effective chip evacuation and high metal removal rates, making the tool suitable for slotting and peripheral milling where a balance of feed and finish is required.

Clear guidance on material suitability and recommended applications

The tool is rated very good for steel, stainless steel and cast iron, while non‑ferrous and special alloys are conditionally suitable. Its right‑hand cutting action and 45° protective chamfer support clean engagement and reduced burr formation on entry. Typical applications include deep pocketing, bore chamfering preparations and finishing passes on components subjected to high tensile loads. Where alloys or very soft non‑ferrous materials are the primary concern, tool selection should consider flute count and coating compatibility to prevent built‑up edge.

FAQ

Can this end mill be used for plunge milling?
Yes. The TECWERK end mill is centre‑cutting, which allows controlled plunge milling and pocket entry without pre‑drilling.

What clamping systems are compatible with the Weldon shank?
The Weldon shank with drive flat is suitable for collets and chucks that accept a 16 mm shank and provides secure torque transmission for the TECWERK cutter.

Is the ALCRONA coating suitable for stainless steel?
Yes. The ALCRONA coating on the HSS‑Co PM substrate improves wear resistance and performance when machining stainless steel with the TECWERK end mill.

Which materials should be avoided with this cutter?
While the tool performs very well in steel, stainless and cast iron, very soft non‑ferrous materials and certain exotic alloys are only conditionally suitable; selection should consider coating and flute geometry.

How does the tool design reduce chatter during deep milling?
The tapered flute root and long‑reach geometry increase stiffness and reduce vibration, producing steadier cutting conditions for deep features.
