TECWERK End Mill DIN 844 Type N – 10 mm, HSS‑Co8, Long 4‑Flute with Weldon Shank

A TECWERK end mill DIN 844 Type N designed for long‑reach milling in steel and castings, offering centre cutting capability and a secure Weldon shank for stable clamping

• HSS‑Co8 construction for high wear resistance
• DIN 844 Type N — long design for deep pocket work
• 4‑flute centre‑cut for axial plunging
• Weldon shank with drive flat for secure clamping

Predictable long‑reach performance for deep machining

The long design, compliant with DIN 844, delivers reach where standard end mills fall short while maintaining predictable results. With a 10 mm diameter and an effective cutting length of 53 mm, the tool permits access into deeper slots and pockets with fewer tool changes. The high‑cobalt steel composition balances toughness and wear resistance to limit premature edge wear when used within its material limits.

Material suitability and recommended application range

Made from HSS‑Co8 (high‑speed steel with around 8% cobalt), the cutter is optimised for machining medium‑strength steels and cast materials where toughness and heat resistance are required. The tool performs very well on steel and castings, while non‑ferrous metals and stainless options are conditionally suitable depending on cutting conditions. As a rule, an uncoated high‑cobalt tool like this one is appropriate for workpiece strengths up to roughly 800 N/mm², with coated variants extending that capability further.

Secure clamping and axial cutting capability

The Weldon shank with drive flat ensures reliable torque transmission in collets or chucks, reducing the risk of slippage during heavy cuts. The 4‑flute, centre‑cut geometry allows for axial plunging as well as peripheral milling, combining material removal efficiency with a good surface finish on successive passes. The cutter is configured for right‑hand cutting, providing conventional chip flow and stable cutting forces for standard machining setups.

Practical considerations to extend tool life and quality

A relief zone measuring 9.5 mm helps reduce rubbing and improves chip evacuation near the shank, which is beneficial in deeper operations. To prolong service life, ensure secure clamping, adjust feeds and speeds to the workpiece and machine rigidity, and employ appropriate coolant or lubrication for the material being machined. Routine inspection of cutting edges will maintain consistent precision and minimise downtime.

FAQ

What materials is this end mill best suited for?
The TECWERK end mill (DIN 844 Type N, SKU 2000866380NW) is very well suited for steel and castings, with conditional suitability for non‑ferrous metals and stainless depending on cutting parameters.

Can this tool be used for plunge milling?
Yes. The cutter’s 4‑flute centre‑cut geometry allows axial plunging as well as conventional peripheral milling, enabling plunge operations where required.

How is the shank secured in the toolholder?
The tool features a Weldon shank with drive flat, designed to prevent slippage and ensure secure clamping under moderate to heavy cutting conditions.

Is the cutter coated?
This specific tool is supplied uncoated in HSS‑Co8; coating can increase surface hardness and allow higher workpiece strength applications, but the supplied variant is optimised for toughness and heat resistance without coating.

What is the effective cutting length and why does it matter?
The effective cutting length is 53 mm, which determines the deep‑reach capability of the cutter and helps assess whether the tool can access the required machining depth without extensions or multiple setups.
