8mm End Mill HSS-Co PM Alcrona Coated 4-Flute Short, Weldon Shank DIN 844 - TECWERK

Benefit from the combination of HSS‑Co PM construction, ALCRONA surface treatment and vibration‑reducing four‑flute geometry for precise, long‑lasting milling; order this end mill directly via Metav Werkzeuge or request application advice from our consultants.

TECWERK End Mill DIN 844 Type N, 8 mm, HSS‑Co PM, ALCRONA, Weldon Shank — 4‑flute, short

The TECWERK end mill DIN 844 Type N is a short, four‑flute cutter designed for stable slotting and peripheral milling of steels, stainless steel and cast iron up to approximately 1000 N/mm².

• HSS‑Co PM core for high toughness
• ALCRONA coating for extended tool life
• Four‑flute design with centre cutting
• Weldon shank, 10 mm shank diameter
• Reduced vibration through unequal flute spacing

Precise performance through engineered materials and coating

The short, Type N cutter combines a HSS‑Co PM substrate with an ALCRONA coating to deliver increased edge strength and wear resistance under intermittent and continuous cutting. Powder‑metallurgy high‑speed steel (HSS‑Co PM) offers a uniform microstructure that improves toughness compared with conventional grades; the coating reduces friction and thermal loading, which together extend service intervals and help maintain consistent part quality. This construction is especially beneficial where tool life and repeatable accuracy directly affect production throughput.

Broad material suitability for workshop and industrial use

Designed for a wide range of applications, the cutter is very well suited to steel, stainless steel and cast iron, while non‑ferrous metals and special alloys are workable with adapted parameters. The tool is specified for materials up to roughly 1000 N/mm², which covers many common structural steels and hardened components encountered in general engineering and toolroom environments. The centre‑cutting geometry permits plunge work and makes the tool suitable for slotting as well as side milling, increasing process flexibility.

Geometry and clamping for improved rigidity and finish

With an 8 mm cutting diameter, 4 cutting edges and a Weldon shank of 10 mm, the cutter offers a compact footprint that increases stiffness in the holder. The effective length 25 mm and short overall length (69 mm) reduce deflection during machining; a tapered flute root improves tool stiffness, while vibration reduction is achieved by unequal flute spacing. These design choices result in steadier cutting forces and a finer surface finish, particularly important for tight‑tolerance or thin‑walled components.

Practical guidance for safe integration and process optimisation

Use secure clamping and a compatible Weldon‑style holder to exploit the cutter’s stiffness advantages. Given the material range, select cutting speeds and feeds appropriate to the workpiece and machine rigidity; applying coolant or lubricant where recommended will prolong tool life and improve chip evacuation. For interrupted cuts or hard conditions, the HSS‑Co PM core and ALCRONA coating combine to resist chipping and thermal wear, reducing unplanned tool changes and supporting more stable cycle times.

FAQ

Which materials can this end mill machine reliably? The TECWERK end mill (DIN 844 Type N, SKU 2000866033NW) is very well suited to steel, stainless steel and cast iron; non‑ferrous materials and special alloys are workable with adjusted cutting data.

What does the ALCRONA coating provide? ALCRONA coating on this TECWERK cutter reduces friction and thermal wear, extending tool life and helping maintain cutting edge integrity under demanding conditions.

Why choose a Weldon shank for this cutter? A Weldon shank provides secure clamping and improved torque transmission for the short, 8 mm cutter, enhancing rigidity and repeatability in milling operations.

How does the cutter reduce vibration during milling? Unequal flute spacing and a tapered flute root on this four‑flute cutter help to disrupt harmonic excitation, resulting in lower vibration and a finer surface finish.

Is the tool suitable for plunge cutting? Yes; the centre‑cutting geometry enables plunge cuts as well as slotting and peripheral milling with the TECWERK end mill.
