12mm Cutter DIN 844 HR Short 4-Flute HSS-Co5 36mm Cutting Length Right-Hand - TECWERK

Take advantage of the combination of HSS‑Co5 material, a secure Weldon shank and a compact 36 mm effective cutting length to maintain stable production in rigid setups; order via Metav Werkzeuge or consult the team for application matching.

End mill DIN 844 Type HR, 12 mm — TECWERK HSS‑Co5, 4‑flute (36 mm effective length)

End mill DIN 844 Type HR, 12 mm is a short, robust HSS‑Co5 cutter designed for precision milling of steel, castings and selected non‑ferrous materials in industrial milling and workshop environments

• HSS‑Co5 for high wear resistance
• Four flutes for stable machining
• 36 mm effective cutting length
• Weldon shank with drive flat

High‑performance material and geometry for demanding steels

The cutter is manufactured from HSS‑Co5 and produced to DIN 844 tolerances, which gives a balance of toughness and hot hardness for interrupted cuts and heavy‑duty milling. The 4‑flute geometry provides a stable cutting action and improved surface finish compared with roughing designs, while the 12 mm diameter keeps rigidity high in short, precise setups. Because the tool is supplied uncoated, it is rated for machining steel up to ca. 800 N/mm²; when used with a suitable coating, application can extend to approximately 1,200 N/mm². This combination of material and geometry translates into consistent tool life and repeatable part quality in series and single‑piece production.

Secure clamping and precise engagement for reliable results

Designed as a short Type HR tool, the cutter features a Weldon shank with a drive flat for positive holder engagement and reduced slippage in heavy cuts. The overall length of 83 mm and the 36 mm effective length keep the working zone compact, limiting overhang and deflection in rigid toolholders. A 45° protective chamfer, central cutting geometry and a back‑relieved, fine cord profile reduce the tendency to chatter and support quick entry into the workpiece. The tool's 11.5 mm free relief and right‑hand cutting direction are optimised for conventional milling cycles and stable axial engagement, which aids reproducible slotting and pocketing tasks on steels and cast components.

Practical advantages for workshops and production lines

In everyday use the short, stiff design of this milling cutter reduces setup time and waste from incorrectly selected overhangs. The four‑cutting‑edge layout delivers a good compromise between chip evacuation and feed capacity, making the tool well suited to semi‑finishing and finishing passes on cast parts and plain steels; non‑ferrous metals are conditionally suitable depending on machining strategy. The Weldon shank simplifies holder compatibility and changeover, so spindle downtime is minimised. For operations seeking to consolidate tooling ranges, the tool's DIN conformity and robust build lower the risk of premature wear and micro‑failures, contributing to predictable process economics and a dependable surface quality on final parts.
