12mm Cylindrical Shank End Mill HSS-Co5 4-Flute 36mm Cutting Length, DIN 844 Weldon - TECWERK

Take advantage of the combination of robust HSS‑Co construction, a Weldon shank for secure tool holding and a 36 mm effective cutting length for longer passes; order the TECWERK HSS‑Co5 end mill directly via Metav Werkzeuge or ask our consultants if needed.

TECWERK HSS‑Co5 End Mill DIN 844 — Ø12 mm, 4‑flute, Weldon shank

TECWERK HSS‑Co5 end mill for short, high‑performance milling of steel and cast iron in general workshop and industrial use

• HSS‑Co5 high‑speed steel body
• 4 cutting edges for smooth chip evacuation
• Weldon shank with drive flat
• Very good for steel and cast iron

Reliable material and standard conformity for consistent results

The cutter is manufactured from HSS‑Co and conforms to DIN 844, delivering a balance of toughness and wear resistance appropriate for demanding shop work. The Ø12 mm geometry combined with a multi‑flute layout reduces tool deflection and supports efficient material removal. The specification emphasises repeatability: the tool’s effective cutting length of 36 mm and overall length of 83 mm are designed to provide extended reach while maintaining stability. These measurable features enable predictable cycle times and support process planning in production environments.

Geometry engineered for secure clamping and precise starts

The tool’s Weldon shank with drive flat ensures secure seating in standard holders, reducing slippage under torque and improving concentricity in interrupted cuts. A centre‑cut configuration allows limited plunge capability for contouring and slotting, while the 45° chamfer at the cutting edge and the relieved helix profile assist chip formation and evacuation. The 4‑flute design promotes smoother surface finishes on finished components and lowers radial vibration, which translates into fewer rejects and more consistent part quality.

Practical applications and machining guidance

This short, multi‑flute end mill is optimised for machining materials with low to medium strength; it is very well suited to steel and cast iron and conditionally suitable for non‑ferrous metals. As supplied uncoated, the tool is appropriate for steels up to ≈800 N/mm²; coating would extend that range but is not present on this item. The cutter is right‑hand cutting, so standard feeds and spindle directions apply. For enquires about feeds, speeds or holder compatibility, the technical team at Metav Werkzeuge can provide specific recommendations to integrate the tool into existing processes.

FAQ

What materials are best machined with this TECWERK end mill?
The TECWERK HSS‑Co5 end mill is very well suited for steel and cast iron and is conditionally suitable for some non‑ferrous metals, as stated in the product specification.

Can the cutter be used for plunging operations?
The cutter features a centre‑cut geometry that permits limited plunge work, though it is primarily intended for peripheral milling and slotting.

How is the tool clamped and secured in the holder?
The Weldon shank with drive flat provides secure clamping and positive torque transmission in standard Weldon holders.

Is the tool coated to extend cutting performance?
This item is supplied uncoated; the technical data notes uncoated performance up to ≈800 N/mm², with higher limits achievable when a suitable coating is applied (coated variants not included here).

Which standard defines the tool shape and dimensions?
The tool conforms to DIN 844, which specifies dimensions and characteristics for short straight shank cutters of this type.
