TECWERK End Mill DIN 844 Type N, Ø16 mm, HSS‑Co8, Weldon, 4‑flute, long

The TECWERK End Mill DIN 844 Type N is a long, four‑flute, centre‑cut HSS‑Co cutter designed for milling operations in steel and cast iron with secure Weldon shank clamping.

• HSS‑Co8 for enhanced wear resistance
• 73 mm effective cutting length for deep machining
• Weldon shank for reliable clamping
• Four flutes for efficient chip evacuation

Durable high‑speed steel for reliable cuts

The use of HSS‑Co8 provides improved red hardness and wear resistance compared with standard high‑speed steel, which translates into longer tool life under heat and load. In practice this means steadier performance when machining steel and cast iron, where the material toughness requires a cutter that maintains its cutting edge. The material choice also allows reliable operation at moderate cutting speeds without a coating, while a coated variant would extend capability for tougher heat‑resistant alloys.

Secure clamping and long reach for deeper operations

A Weldon shank with a drive flat ensures secure axial and torsional clamping in standard toolholders, reducing the risk of slippage during heavy engagement. The 73 mm effective cutting length combined with a total length of 123 mm gives extra reach for slotting and deep pocketing where standard stub cutters fall short. The long design keeps the cutter accessible to deeper work while the cylindrical shank with a drive flat maintains stability for consistent surface quality.

Geometry optimised for smooth chip control

The four‑flute configuration offers a balance between chip removal and surface finish: more cutting edges than a two‑flute allow finer finishes, while flute geometry eases evacuation when cutting ferrous materials. The tool is centre‑cutting and right‑handed, enabling safe plunge starts and conventional milling directions. This geometry reduces chatter and supports predictable chip flow, which is especially useful when cutting cast iron or interrupted surfaces.

Conformance and workshop advantages

Manufactured to DIN 844 Type N specifications, this long end mill adheres to a recognised industrial standard that simplifies tool selection and replacement. The cutter is indicated as very well suited for steel and cast iron, with conditional suitability for non‑ferrous metals and stainless steels; when combined with appropriate coatings, the tool’s capacity can extend further. For workshops seeking a robust, easy‑clamp cutter for general to demanding milling tasks, the construction and geometry offer a pragmatic blend of durability and versatility.

FAQ

What materials is this end mill best suited for?
The TECWERK end mill is very well suited for steel and cast iron; suitability for non‑ferrous metals and stainless steel is conditional and depends on cutting parameters and whether a coating is applied.

Can this cutter be used for plunge milling?
Yes. The centre‑cutting geometry and four‑flute design allow controlled plunge starts with the TECWERK long end mill, subject to correct feeds and speeds.

How does the Weldon shank benefit machining stability?
The Weldon shank provides a drive flat for secure clamping in collet chucks or holders, reducing slippage and improving torque transmission during heavier cuts.

Is the tool supplied with any coating?
The supplied tool is uncoated; HSS‑Co8 stock offers good red hardness, and a coated variant would extend capability for higher temperature or abrasive applications.

What standard does the cutter conform to and why does that matter?
Conformance to DIN 844 Type N ensures standardised geometry and dimensions, facilitating replacement and predictable performance across industrial toolholders.
