Schaftfräser D844 Typ N D.6mm — long HSS‑Co8, TiCN‑coated 4‑flute end mill (TECWERK)

The Schaftfräser D844 Typ N D.6mm is a long, four‑flute end mill designed for general and continuous milling of steel, stainless steel and cast materials, combining DIN 844 geometry with a Weldon shank for secure clamping

• HSS‑Co8 for high heat resistance
• TiCN coating for extended tool life
• Four cutting edges for high removal rates
• Weldon shank with drive flat for secure clamping

Longer tool life through heat‑resistant materials and coating

The long design of this cutter is built from HSS‑Co8, a cobalt‑alloyed high‑speed steel that maintains hardness at elevated temperatures, and is finished with TiCN to reduce wear. Together these features increase resistance to abrasion and adhesive wear, which means fewer tool changes and longer service intervals. The DIN‑standard geometry also ensures consistent performance across batches, supporting repeatable process results. The clear benefit is a reduction in downtime and steady machining quality under demanding conditions.

Reliable machining of common industrial materials

This tool is optimised for machining steel, stainless steel and castings, with very good suitability noted for these materials; non‑ferrous metals and special alloys are conditionally suitable. The cutter is centre cutting, allowing plunge operations, and features right‑hand cutting for conventional spiral chip evacuation. With a capacity up to approximately 800 N/mm² when uncoated and up to around 1,200 N/mm² when coated, the geometry supports higher productivity while preserving edge integrity — an advantage when running mixed batches or switching between production and repair work.

Secure clamping and stable geometry for accurate results

With a Ø6 mm shank and 30 mm cutting length inside a 68 mm total length, the tool offers the reach required for deeper features while maintaining rigidity when clamped correctly. The Weldon shank with drive flat provides positive engagement in standard chucks and holders, reducing slippage and improving concentricity. The four‑flute layout balances metal removal and surface finish, making the cutter suitable for operations where dimensional accuracy and repeatability are priorities.

Efficient material removal with industrial compatibility

The four‑edge configuration favours higher feed rates and improved surface finish when compared with two‑flute alternatives, while the TiCN layer reduces built‑up edge on sticky materials. The tool’s DIN 844 Type N profile makes it compatible with established machining strategies and holder systems, simplifying integration into existing workflows. For procurement, the combination of durable substrate and coating produces a favourable total cost of ownership through reduced tool consumption and fewer process interruptions.

FAQ

Is this cutter suitable for plunge milling and slotting?
Yes. The D844 Type N cutter is centre cutting, which allows plunge operations and makes the tool suitable for slotting and limited plunging duties with TECWERK’s long HSS‑Co8 design.

Which materials perform best with this end mill?
The tool shows very good suitability for steel, stainless steel and castings; non‑ferrous metals and special alloys are conditionally suitable depending on machining parameters and workpiece hardness.

What advantages does the TiCN coating provide?
The TiCN coating improves wear resistance and reduces adhesive build‑up, increasing tool life and enabling higher cutting parameters compared with an uncoated tool.

How does the Weldon shank help in production environments?
The Weldon shank with drive flat ensures secure clamping and reduces slippage in standard tool holders, supporting improved concentricity and repeatable results in production setups.

Can the tool handle hardened materials?
The cutter is designed primarily for low to medium‑strength materials; coated geometry extends the workable hardness range up to approximately 1,200 N/mm² under suitable conditions.
