End mill DIN 844 Type HR, 12 mm, HSS‑Co PM, ALCRONA, Weldon – TECWERK

The End mill DIN 844 Type HR is a long‑reach, centre‑cutting four‑flute tool designed for heavy‑duty milling in demanding steels and stainless applications

• ALCRONA-coated for extended tool life
• HSS‑Co PM substrate for toughness
• Centre-cutting, 4 flutes for effective cutting
• Weldon shank with drive flat for secure clamping

Reliable performance in demanding steels

The HSS‑Co PM substrate delivers high toughness and thermal resistance, making this long version suitable for machining materials up to 1400 N/mm² tensile strength. The tool’s geometry, with a conical flute root, increases stiffness along the cutting edge and reduces chatter during long‑reach operations, which translates into steadier feeds and more consistent component dimensions. This design choice benefits production runs that require repeatable accuracy and fewer rejected parts.

Longer tool life and predictable wear behaviour

The ALCRONA coating reduces friction and heat build‑up at the cutting edge, slowing flank wear and preserving the sharpness of the geometry over extended cycles. For shops aiming to maximise tool utilisation, the combination of coating and powder‑metallurgy steel offers a measurable reduction in replacement frequency. For those less familiar with coatings: ALCRONA forms a hard, low‑friction layer that delays abrasion and protects against high temperature degradation during hard cutting.

Secure clamping and reliable cutting action

A Weldon shank with drive flat provides positive axial and rotational grip in set‑screw holders, reducing the risk of slippage under high torque. The centre‑cutting tip enables light plunge cuts and fast tool engagement, while the 4 flutes balance chip evacuation with surface finish quality. The 45° protection chamfer on the margin reduces corner chipping and extends the usable life of each insert, giving a predictable edge condition for demanding finishing passes.

Practical fit for workshop and CNC use

With a 12 mm diameter, overall length of 110 mm and an effective length of 63 mm, the tool is optimised for long‑reach tasks where rigidity and controlled chip flow are essential. The design is right‑hand cutting and features a cylindrical shank with drive flat for standard clamping systems. Material suitability is clearly defined: very good for general steel and stainless steel, very good for cast materials, and conditional for non‑ferrous metals and specialised alloys — enabling confident tool selection for mixed‑material production environments.

FAQ

What materials is this end mill best suited for?
The TECWERK end mill (SKU 2000866075NW) is optimised for steel and stainless steel, with very good performance on cast materials; non‑ferrous metals and special alloys are addressed conditionally depending on cutting strategy and speeds.

Can the tool perform plunge or helical entry operations?
Yes, the centre‑cutting geometry allows plunge and helical entries, making the tool suitable for applications that require direct engagement into the workpiece.

Which clamping system is recommended for secure use?
A set‑screw holder for Weldon shanks is recommended to ensure axial and rotational security using the drive flat; this reduces the chance of slippage during heavy cuts.

What are the key dimensional data for workshop planning?
This item is a 12 mm diameter long end mill with 110 mm overall length, 63 mm effective length and 4 mm cutting length, intended for long‑reach milling where stiffness and chip control are important.
