14mm Solid Carbide End Mill HSS-Co8 TiCN Coating 63mm Cutting Length DIN 844 - TECWERK

Take advantage of high red hardness from HSS‑Co8 combined with a TiCN coating for longer tool life and higher cutting performance; long effective length (63 mm) allows deeper milling operations; order directly via Metav Werkzeuge or consult our specialists for application advice.

TECWERK End mill D844 Type N, 14 mm — TiCN-coated HSS‑Co8, 4‑flute, Weldon shank

The TECWERK End mill D844 Type N is a long, centre-cut, 4‑flute cutter designed for precise milling of medium-strength steels, stainless steel and cast materials

• HSS‑Co8 for improved red hardness
• TiCN coating for extended wear resistance
• 4‑flute geometry for fine surface finish
• Weldon shank with 12 mm clamping section

Robust material and coating for extended tool life

The combination of HSS‑Co8 substrate and TiCN surface treatment delivers a balance of toughness and heat resistance that suits demanding milling tasks. The cobalt‑alloyed high‑speed steel increases red hardness, helping the cutter retain its cutting edge at elevated temperatures, while the TiCN layer reduces adhesive wear and improves resistance to abrasion. This pairing makes the tool particularly effective when increased cutting performance is required without sacrificing reliability, allowing higher sustained cutting speeds than uncoated equivalents.

Geometry tailored for accuracy and deeper reach

With a 14 mm diameter and an effective length of 63 mm, this long version offers reach for deeper slots and stepped features while maintaining stability. The 4‑flute design provides a fine surface finish and reduces axial run-out effects, whereas the centre‑cut geometry permits limited plunge milling. A Weldon style clamping face on the cylindrical shank ensures secure retention in holders that accept a flat, enhancing axial torque transmission during heavy cuts. The overall length of 110 mm balances reach with rigidity for repeatable results.

Clear selection for common workshop applications

Specified to the DIN 844 form (Type N), the cutter is intended primarily for materials with low to medium tensile strength up to approximately 800 N/mm² when used uncoated, and up to 1,200 N/mm² when used with the TiCN coating. Suitability is rated very good for steel, stainless steel (INOX) and cast materials, with conditional suitability for non‑ferrous metals and special alloys. This clarity helps procurement and process engineers match the tool to the correct component families, reducing trial‑and‑error and improving first‑pass yield.

Practical use and handling recommendations

For best results, secure the Weldon shank in an appropriately sized holder and prefer rigid setups to exploit the cutter’s long profile. Coolant use is recommended for continuous heavy cuts and stainless applications to moderate temperature and chip adhesion. Feed and speed should be selected in line with machine rigidity and material; the enhanced TiCN wear properties allow more aggressive parameters than uncoated HSS in many cases.

FAQ

Is this cutter suitable for stainless steel workpieces?
The TECWERK end mill D844 Type N is rated very good for INOX; the HSS‑Co8 substrate combined with the TiCN coating improves performance on stainless materials.

Can the tool be used for plunge milling?
Yes, the centre‑cut geometry permits limited plunge milling; the tool is specified as centre‑cut in the D844 Type N form.

What clamping does the cutter require?
The cutter features a cylindrical shank with a Weldon flat; a holder accepting a 12 mm shank with a clamp screw on the flat ensures secure retention.

Which materials are only conditionally suitable?
Non‑ferrous metals and special alloys are listed as conditionally suitable for this cutter; machining parameters and coating choice influence performance.
