Take advantage of the combination of HSS‑Co5 construction, a 4‑flute finishing geometry and a secure Weldon shank to keep machining consistent and clamping reliable in short‑run and series production; order directly via Metav Werkzeuge or consult our specialists for application advice.

TECWERK HR End Mill Ø14 mm (HSS‑Co5), 4‑flute, DIN 844

The TECWERK HR end mill is a short, four‑flute DIN 844 cutter designed for efficient milling and controlled plunge operations in steel and cast iron components.

• HSS‑Co5 for high heat resistance
• 4‑flute design for smooth finishing
• Weldon shank with drive flat for secure clamping
• DIN 844, type HR — centre‑cut for plunge milling

Consistent material performance for demanding steels

The combination of HSS‑Co5 substrate and a compact geometry delivers predictable tool life when machining medium‑strength steels. The cobalt‑alloyed high‑speed steel increases red hardness and wear resistance, which translates into longer service intervals under elevated cutting temperatures. With a Ø14 mm cutting diameter and a 4‑flute arrangement, the cutter balances material removal rate and surface finish, enabling efficient finishing passes without sacrificing dimensional control. The tool is specified for uncoated use up to approximately 800 N/mm², offering a clear guideline for process planning in mixed‑material shops.

Stable clamping and machine compatibility reduce downtime

A Weldon shank with a defined drive flat ensures positive engagement in common toolholders and hydraulic chucks, reducing the risk of slippage during interrupted cuts. The cylindrical shank with drive flat suits standard toolholders and allows for quick tool changes on conventional and CNC milling machines. The short design and the effective length 36 mm minimise overhang, improving rigidity and enabling higher cutting parameters on stable setups. This construction supports reproducible results across multiple operators and shifts, contributing to predictable production throughput.

Geometry engineered for plunge and profile milling

The HR type conforms to DIN 844, featuring a centre‑cut capability that permits safe plunge milling as well as peripheral passes. A 45° chamfer at the entry edge helps control burr formation and reduces the tendency for corner chipping when entering the workpiece. The tool’s finely relieved cord profile and precise cutting edge preparation enhance chip control and surface integrity, particularly in cast iron where brittle chips can otherwise affect finish. These geometric choices reduce secondary operations and support consistent part quality in small to medium batch sizes.

Application suitability and shopfloor benefits

This cutter shows very good suitability for steel and cast iron, with conditional application to non‑ferrous metals; its uncoated state is optimised for the stated strength range. The combination of a robust substrate and a four‑cut geometry results in a favourable surface texture on machined faces, reducing rework and inspection effort. For tool room managers and production engineers, the HR short end mill presents a pragmatic solution where a balance of finish, rigidity and plunge capability is required. When higher strength materials or elevated speeds are planned, consider a coated variant to extend the tool’s top‑end capability.

FAQ

What materials is this cutter best suited for?
The TECWERK HR end mill (SKU 2000866498NW) is very well suited to steel and cast iron; non‑ferrous metals are conditionally suitable with this uncoated tool.

Can the cutter be used for plunge milling?
Yes, the HR geometry includes a centre‑cut feature that allows controlled plunge operations and makes the tool suitable for dowel‑type pockets and slotting where plunge entry is required.

What clamping systems are compatible with the shank?
The Weldon shank with drive flat is compatible with standard Weldon holders and many collet and chuck systems that accept cylindrical shanks with flats, ensuring secure clamping during interrupted cuts.

Is the cutter coated and how does that affect performance?
The supplied tool is uncoated; performance guidelines indicate suitability up to ca. 800 N/mm² in uncoated form. For higher strength materials or elevated cutting speeds, a coated variant is recommended to extend capability.

How does the four‑flute design affect surface finish?
The 4‑flute geometry delivers a good compromise between chip evacuation and surface integrity, producing smoother finishes on peripheral passes while maintaining sufficient cutting edges for productive feeds.
