3mm Solid Carbide End Mill HSS-Co8 TiCN Coating 4 Flute 4mm Cut Short DIN 844 - TECWERK

Combine the wear resistance of TiCN with the heat resilience of HSS‑Co8 and the secure clamping of a Weldon shank for consistent small‑diameter milling results; order the TECWERK end mill via Metav Werkzeuge or consult our specialists for application advice.

TECWERK DIN 844 Type N 3 mm HSS‑Co8 TiCN Weldon End Mill, 4‑flute, short

The TECWERK DIN 844 Type N 3 mm end mill is a short, 4‑flute, centre‑cutting HSS‑Co tool with TiCN coating designed for precise milling of steels, stainless steel and cast iron in workshop and light industrial settings.

• TiCN coating for extended tool life
• HSS‑Co8 alloy for heat resistance
• Short 4‑flute design for rigidity
• Weldon shank, 6 mm for secure clamping

High rigidity and predictable finish for small diameters

This short 4‑flute design follows the DIN 844 Type N specification and offers a compact geometry that improves rigidity and reduces chatter during slotting and finishing operations. The combination of a reduced 3 mm cutting diameter and a 52 mm overall length concentrates stiffness at the cutting zone, which helps to produce consistent surface quality and repeatable dimensional results. The 4‑flute layout supports better axial stability and a finer feed per tooth, making the tool suitable for finishing passes where accuracy and tool life are priorities.

Coating and substrate engineered for tougher applications

A TiCN coating on an HSS‑Co8 substrate increases surface hardness and wear resistance compared with uncoated high‑speed steel, which improves performance on abrasive stainless steels and cast materials. With the coated tool, machining of steels up to about 1000 N/mm² is feasible, whereas the uncoated substrate is best applied up to around 800 N/mm². These characteristics translate into longer intervals between tool changes and fewer rework cycles, supporting efficient production rhythms in small workshops and maintenance shops alike.

Secure clamping and practical workshop integration

The Weldon flat on the shank and a 6 mm shank diameter provide secure clamping in standard holders, reducing slippage during interrupted cuts. The tool’s centre‑cutting geometry allows limited plunging and makes it versatile for pocketing and contouring tasks. With a 4 mm cutting length and an effective length of 8 mm, the tool balances accessibility and rigidity for short‑to‑medium depth features. Right‑hand cutting orientation matches common machining setups, simplifying integration into existing tool inventories.

FAQ

Which materials is this milling cutter best suited to machine?
The TECWERK DIN 844 Type N 3 mm end mill is very well suited for steel, stainless steel and cast iron; non‑ferrous metals and special alloys are suitable in conditional applications according to machining strategy.

What advantages does the TiCN coating provide?
The TiCN coating on the HSS‑Co substrate improves surface hardness and wear resistance, enabling longer tool life and allowing coated cutting up to approximately 1000 N/mm² in tougher steels.

Can the tool be used for plunging operations?
Yes, the cutter is centre‑cutting, so limited plunging and entry moves are possible, which is useful for pocketing and contouring without pre‑drilling in many workshop tasks.

What does the Weldon shank offer for clamping?
The Weldon shank with a 6 mm diameter secures the tool in standard holders and reduces the risk of slippage, providing reliable torque transmission for interrupted cuts and penetrating features.

Which standard does this tool conform to and what is its SKU?
This tool conforms to DIN 844 Type N and is listed under SKU 2000866346NW for reference in ordering and inventory.
