Take advantage of the combination of HSS‑Co8 durability, a TiCN coating and a secure Weldon shank to keep milling cycles consistent and tool changes fast; order this long DIN‑844 end mill directly via Metav Werkzeuge or consult our technicians for application-specific advice.

TECWERK End Mill D844 Type N, 12 mm – HSS‑Co8 TiCN, 4‑flute long

A TECWERK End Mill D844 Type N designed for long‑reach milling of medium‑strength steels and stainless steel in industrial and workshop production.

• HSS‑Co8 substrate for increased heat resistance
• TiCN coating for extended tool life
• 4‑flute geometry for smooth material removal
• Weldon shank for secure clamping

Consistent high‑feed machining for medium‑strength materials

The long version of this DIN‑844 end mill combines a HSS‑Co8 substrate with a TiCN surface treatment to raise thermal stability and abrasion resistance. This means more consistent performance when machining components in low to medium tensile ranges; the tool is specified for materials up to approximately 800 N/mm² when uncoated and up to 1,200 N/mm² with the coating applied. The result is improved process reliability and longer intervals between tool changes.

Stable clamping and runout control for accurate finishes

A Weldon shank and a cylindrical shank with drive flat provide secure toolholding that reduces slippage and runout in rigid setups. The long effective length of 63 mm delivers reach without compromising stability in properly supported fixtures. Combined with the 11.5 mm relief, the design ensures stable chip evacuation and consistent surface quality on lengthwise passes, which supports predictable cycle times and repeatable tolerances.

Versatile material suitability for stainless and cast components

This end mill is centre cutting, permitting plunge as well as peripheral milling operations, and is categorised for very good performance on steel, stainless steel and cast materials. Non‑ferrous metals and special alloys are conditionally suitable, so process trials are recommended for aluminium or high‑temperature alloys. The four‑flute geometry balances chip load and surface finish, making it effective for through‑cuts and finishing passes in many common workshop tasks.

Practical design that reduces setup time and improves throughput

Conforming to DIN 844 and featuring a 12 mm diameter with a 63 mm effective length, the tool is optimised for longer reach jobs where stability and wear resistance matter. The 4‑flute profile offers a higher volumetric removal rate compared with two‑flute cutters while maintaining a fine surface. For production environments seeking fewer tool swaps and dependable repeatability, the combination of material, coating and shank design supports efficient integration into standard tool management systems.

FAQ

What materials is this end mill best suited to machine?
The TECWERK End Mill D844 Type N is very well suited to machining steel, stainless steel and cast materials; non‑ferrous metals and special alloys are conditionally suitable and should be validated in trials.

Can the cutter be used for plunge milling?
Yes. The tool is centre cutting, which allows controlled plunging operations in addition to peripheral milling for greater process flexibility.

How is the tool clamped in the holder?
Clamping is via a Weldon shank with drive flat, providing secure holding for heavy cuts and minimising slippage in rigid setups.

What benefits does the TiCN coating provide?
The TiCN coating increases surface hardness and heat resistance, extending tool life and improving wear performance compared with uncoated variants.

Which industry standard does the tool comply with?
The cutter is manufactured to DIN 844 specifications and is delivered in the long Type N geometry for extended reach applications.
