10mm Solid Carbide End Mill DIN 844 HR 4-Flute Long ALCRONA Coating, Weldon Shank, 45° Chamfer - TECWERK

Benefit from extended tool life and secure clamping thanks to a HSS‑Co PM core and ALCRONA coating, combined with a Weldon shank for reliable power transmission; order directly via Metav Werkzeuge or consult our specialists for application guidance.

End mill DIN 844 Type HR, 10 mm, HSS‑Co PM, ALCRONA — TECWERK

A End mill DIN 844 Type HR for long‑reach milling of steel, stainless steel and cast iron, designed for reliable performance up to approx. 1400 N/mm².

• HSS‑Co PM for high wear resistance
• ALCRONA coating for extended life
• 4‑flute long design for deep pockets
• Weldon shank with drive flat for secure clamping

Durable core and coating for sustained performance

The End mill DIN 844 Type HR combines a HSS‑Co PM substrate with an ALCRONA coating to balance toughness and wear resistance for demanding tasks. The powder‑metallurgy high‑speed steel offers improved red hardness and edge stability compared with conventional HSS, while the coating reduces adhesion and abrasion during prolonged cuts. The tool is specified for materials up to ~1400 N/mm², enabling consistent metal removal rates when machining medium‑to high‑strength steels. With a 4‑flute geometry and centre cutting capability, the cutter is suitable for axial entry and produces predictable chip formation in interrupted and continuous cuts.

Secure clamping and geometry for stability in deep machining

The long‑reach version features a Weldon shank with a drive flat to prevent slippage in the holder and maintain concentricity under load. A tapered flute root improves the bending stiffness of the cutting section, reducing deflection and chatter when reaching into pockets or slots. The long design permits access to deeper cavities without sacrificing stability, and the 45° protective chamfer on the cutting edge lowers the risk of edge damage during approach. Right‑hand cutting ensures conventional machining behaviour and compatibility with standard milling strategies.

Versatile application with predictable surface quality

Configured as a four‑edged tool with centre cutting, the cutter delivers a balance of feed capacity and finish quality. It is rated very good for steel, very good for stainless steel and very good for cast iron, while non‑ferrous metals and some special alloys are listed as conditionally suitable — a detail that helps planners select the correct tool for each workpiece. The geometry supports stable chip evacuation and a consistent surface finish, making the tool appropriate for both roughing in constrained geometries and finishing passes where dimensional control is required. Operators benefit from reduced tool changes and repeatable process outcomes when the cutter is matched to the stated material classes.

FAQ

What materials is this end mill suitable for?
The TECWERK end mill is specified as very good for steel, very good for stainless steel and very good for cast iron; non‑ferrous metals and certain special alloys are listed as conditionally suitable.

Can the cutter perform axial plunging?
Yes, the centre cutting geometry allows axial entry and controlled plunging operations when using the TECWERK DIN 844 Type HR tool.

How does the Weldon shank improve machining reliability?
The Weldon shank with drive flat provides secure clamping and torque transmission, reducing the risk of slippage for the TECWERK end mill during heavy or interrupted cuts.

Is the coating helpful for stainless steel applications?
The ALCRONA coating on the TECWERK cutter reduces adhesion and wear, supporting longer tool life and improved performance when machining stainless steel.

What benefits does the tapered flute root provide?
A tapered flute root increases the bending stiffness of the cutting section, lowering deflection and chatter for more stable cutting with the TECWERK long‑reach design.
