End mill DIN 844 Type HR — 12 mm, HSS‑Co5, TiCN (TECWERK)

The End mill DIN 844 Type HR is a short four‑flute shank cutter designed for demanding general‑purpose milling and cast‑iron work, featuring a TiCN coating and Weldon shank for secure clamping

• HSS‑Co5 M35 for improved hot hardness
• TiCN coating for longer tool life
• 4‑flute geometry for smooth surface finish
• Weldon shank with drive flat for secure clamping

High‑performance cutting for tougher materials

The tool combines HSS‑Co5 substrate and a TiCN coating to deliver elevated wear resistance and thermal stability. Conforming to DIN 844 Type HR, the geometry includes a centre cutting capability and a short profile that enables controlled entry and exit in pocketing operations. With the coated version, the tool is rated for materials up to about 1200 N/mm²; the uncoated substrate is suitable for up to around 800 N/mm², allowing selection according to cycle demands and workpiece strength.

Optimised for steel and cast‑iron applications

The four‑flute layout and the finely honed cord profile give good axial stability and a consistent surface finish, making this cutter especially effective in steel and cast iron where dimensional accuracy matters. Non‑ferrous metals, certain special alloys and stainless steels are machinable with care, but the tool’s strengths are most apparent where hardness and wear resistance are required. The short flute length reduces deflection and improves controllability during interrupted cuts.

Practical dimensions and secure clamping for shop use

The cutter is supplied with a 12 mm cylindrical shank and a Weldon (drive flat) configuration for reliable retention in set‑screw holders. Key dimensions include an overall length of 83 mm, an effective cutting length of 36 mm and a relief/ground length of 11.5 mm, offering a compact, rigid package for tool‑holder assemblies. The right‑hand cutting direction and the precision shank ensure repeatable positioning and safe tool changeover in production environments.

Productivity gains and tool‑life economy

Applying the TiCN coating reduces adhesive wear and allows higher cutting speeds compared with uncoated HSS‑Co5, which translates into shorter cycle times and fewer tool changes. The combination of a short, stiff design and a four‑edge geometry minimises vibration and produces consistent chip control, improving surface quality and lowering rework risk. Further technical guidance and application charts are available for optimising feeds and speeds for specific machines and materials.

FAQ

What materials is this end mill best suited for?
The TECWERK end mill (DIN 844 Type HR, SKU 2000866512NW) is very well suited to steel and cast iron; non‑ferrous metals, special alloys and stainless steel are machinable with appropriate parameters and tool path planning.

Can the cutter be used for plunge milling?
The centre‑cutting design permits limited plunge operations; the short profile and four‑flute geometry favour controlled entry, but plunge depth should be matched to the tool’s effective length and machine capabilities.

How is the cutter clamped in the holder?
The Weldon shank with drive flat is designed for set‑screw or clamping holders that accept a 12 mm shank, providing reliable torque transmission and quick tool changes.

Does the TiCN coating change machining parameters?
Yes, TiCN increases wear resistance and allows higher cutting speeds compared with uncoated HSS‑Co5; feed and speed adjustments should be made according to the material and the rigidity of the setup.

Is the tool suitable for finishing operations?
The four‑flute geometry and honed cord profile yield a good surface finish and dimensional control, making the cutter suitable for finishing passes where stiffness and low vibration are required.
