TECWERK End Mill DIN 844 Type N, Ø12 mm — Long 4‑flute HSS‑Co8 cutter with Weldon shank

TECWERK End Mill DIN 844 Type N Ø12 mm is a long, centre‑cut high‑speed cobalt end mill designed for general workshop and production milling of steels, cast iron and selected non‑ferrous materials

• HSS‑Co8 construction for high wear resistance
• Four‑flute design for stable milling
• Weldon shank (drive flat) for secure clamping
• DIN 844 Type N — long centre‑cut geometry

Durable material and geometry for consistent performance

Built from HSS‑Co8, this long DIN 844 Type N cutter offers a balance between toughness and wear resistance that suits repetitive workshop tasks. The cobalt alloy improves thermal stability under load, which helps to preserve the cutting edge when machining medium‑strength steels. The four‑flute arrangement increases engagement and chip load capacity, producing a steady cut and improved surface quality compared with two‑ or three‑flute variants. The long design provides access to deeper features while the centre‑cut geometry enables limited plunge operations without the need for specialised plunging tools.

Secure clamping and vibration control for repeatable accuracy

A Weldon shank (drive flat) ensures positive drive transmission to the tool holder and reduces slippage under higher torque, making the cutter suitable for set‑screw holders and many modular tool‑holding systems. The combination of a Ø12 mm shank and matching shaft diameter promotes rigidity, while the overall long form factor and 4‑flute geometry help to dampen chatter. These characteristics translate into more consistent tolerances and fewer rework cycles in routine milling operations, improving throughput and process reliability in small‑ to medium‑batch production.

Application range and material suitability explained

This cutter is engineered primarily for machining steels and cast iron, with a very good suitability for these materials; non‑ferrous metals and stainless steel are conditionally suitable depending on cutting data and workpiece hardness. Where surface hardness and tensile strength increase, adjustments to cutting speed and feed are recommended. The tool’s effective length of 63 mm gives sufficient reach for many pocketing and profiling tasks while maintaining stability. For unfamiliar applications, consult technical data to match cutting parameters and workpiece conditions.

Practical handling notes and workshop integration

As a right‑hand cutting long end mill with a Weldon drive, the cutter integrates easily into standard set‑screw holders and many modular clamping systems. The cutter’s free relief length and flute geometry reduce heat buildup under typical cutting conditions for HSS‑Co tools; nevertheless, appropriate coolant or flood lubrication is advised where heavy material removal is required. For reliable selection of holders and machining parameters or to compare with coated alternatives, Metav Werkzeuge’s product specialists provide application advice and supply logistics from their Emmerich facility.

FAQ

What materials is this end mill suitable for?
The TECWERK End Mill DIN 844 Type N (SKU 2000866382NW) in HSS‑Co8 is very well suited to machining steel and cast iron; non‑ferrous metals and stainless steel are conditionally suitable depending on cutting data and workpiece hardness.

Is the cutter supplied with a coating?
This specific cutter is supplied uncoated; the tool is manufactured from HSS‑Co8 without a surface coating.

What does DIN 844 Type N mean for the cutter’s geometry?
DIN 844 Type N indicates a long shank, centre‑cut end mill geometry with robust flute form suitable for general milling tasks and limited plunge cutting.

Which clamping system is required for secure use?
The Weldon shank (drive flat) is designed for secure clamping in set‑screw holders and compatible modular tool holders that accept a drive flat for positive torque transmission.

Can the cutter be used for plunge milling?
The centre‑cut geometry allows limited plunging operations; for continuous or deep plunge work, consult Metav Werkzeuge for recommended tooling options.
