12mm Solid Carbide HSS-Co End Mill DIN 844 Short 36mm Cut Length 4-Flute Right-Hand - TECWERK

The combination of HSS‑Co5 wear resistance, centre‑cutting geometry and a secure Weldon shank ensures stable, repeatable performance in short, precision milling tasks. Order the TECWERK HSS‑Co5 end mill directly via Metav Werkzeuge or ask our consultants if needed.

TECWERK HSS‑Co5 end mill — 12 mm diameter, 36 mm effective length, Weldon TW

The TECWERK HSS‑Co5 end mill is designed for short, high‑precision milling operations in steel and cast iron where repeatable results and reliable clamping are required

• HSS‑Co5 for increased wear resistance
• Centre‑cutting for plunge capability
• Weldon shank for firm tool clamping
• DIN 844 short multi‑flute design

Consistent cutting performance for short, accurate passes

The combination of HSS‑Co5 steel and a compact multi‑flute geometry delivers a balance of toughness and edge retention that benefits interrupted and short‑run milling. The 12 mm diameter with a 36 mm effective length and a 4 mm cutting length gives a rigid working length that reduces deflection and vibration during milling, improving dimensional consistency. The tool conforms to DIN 844, a standard that aligns form and tolerances for short shank cutters, which helps maintain predictable tool behaviour in production setups.

Secure clamping and improved chip flow for reliable machining

A Weldon shank (Weldon TW) provides positive drive under high torque and prevents rotation in the holder, making the tool suited to aggressive feed rates within its application range. The 45° chamfer on the cutting edge and the relieved cord‑style profile aid chip formation and evacuation, reducing heat build‑up and extending edge life. The centre‑cutting geometry enables controlled plunge entry when needed, while the short multi‑flute arrangement increases axial stiffness and lowers the tendency to chatter, offering more predictable surface finish and cycle times.

Clear material recommendations and typical uses

The cutter is specified for machining workpieces of low to medium strength up to approximately 800 N/mm² with an uncoated tool, with higher limits possible when a coated version is used. According to the original specification, suitability is very good for steel and cast iron and conditionally suitable for non‑ferrous metals. Typical applications include face milling, slotting and light plunge operations in component finishing, prototype work and workshop rework where a short, robust cutter is preferred.

FAQ

What materials is this cutter suited to?
The TECWERK HSS‑Co5 end mill (SKU 2000866426NW) is specified as very well suited for steel and cast iron; non‑ferrous metals are marked as conditionally suitable according to the tool data.

Does the tool allow plunge cutting?
Yes. The centre‑cutting geometry of this end mill enables controlled plunge entries as well as conventional side milling.

What does the Weldon TW shank mean for clamping?
A Weldon shank provides a flat for set screws in the holder, ensuring secure axial and rotational drive; the Weldon TW configuration helps prevent slippage under higher torque.

Is the cutter supplied with a coating?
The tool is supplied uncoated according to the available data, constructed from HSS‑Co5 high‑speed steel for improved toughness.

What are the key dimensions to consider for holder selection?
Key dimensions: 12 mm diameter, 12 mm shank diameter, 36 mm effective length and 83 mm overall length — use these when selecting the correct holder and stick‑out.
