Schaftfräser DIN 844 Typ N, Ø14 mm, HSS‑Co8 — TECWERK end mill, 4‑flute, long

The Schaftfräser DIN 844 Typ N is a long, four‑flute HSS‑Co8 end mill designed for general milling of steels and castings where high material removal rates and repeatable dimensional accuracy are required

• HSS‑Co8 for high wear resistance
• 63 mm effective cutting length
• 4 cutting edges for smooth material removal
• Weldon shank Ø12 mm for secure clamping

Consistent performance through geometry and material

The tool is made from HSS‑Co8, a cobalt‑alloyed high‑speed steel that raises red‑hardness and wear resistance compared with standard HSS. The DIN 844 Type N profile and four flutes provide a balanced cutting action that reduces vibration and promotes consistent chip evacuation. With a 63 mm effective cutting length and a Ø14 mm cutting diameter, this cutter is engineered to maintain form accuracy over longer passes. The combination of alloyed steel and optimized flute geometry results in predictable tool life and fewer tool changes, supporting continuous production with reduced downtime.

Suited materials and practical limits for workshop use

This end mill offers very good suitability for steel and cast iron, while non‑ferrous and stainless materials are classified as conditionally suitable depending on cutting data and coolant. In practice, the uncoated variant is recommended for workpieces up to approximately 800 N/mm²; when a suitable coating is applied, the operational range extends toward 1,200 N/mm², enabling tougher applications. The right‑hand cut geometry aligns with standard milling setups and makes the cutter a versatile choice for both roughing and semi‑finishing operations in mechanical and toolmaking environments.

Secure clamping and machine compatibility

A Weldon shank with a 12 mm diameter provides a reliable means of clamping in setscrews or hydraulic chucks, minimising runout and slippage during high‑load cuts. The tool’s 11.5 mm relief behind the cutting edges helps to avoid rubbing and reduces heat transfer to the shank, which supports longer service life in repetitive cycles. The four‑edge design also lowers cutting forces per tooth, which can improve surface finish and reduce spindle load on medium‑power machining centres and vertical mills typical in small to medium workshops.

Efficiency gains and recommended usage

Using a long Type N end mill such as this one improves reach for deeper cavities and long‑step operations without compromising rigidity when correctly clamped. The four‑flute configuration helps to maintain a fine balance between metal removal rate and surface integrity, delivering measurable productivity improvements in batch production. For best results, match feeds and speeds to machine rigidity and workpiece material, and consider a suitable coating if machining harder steels or when higher thermal stability is required to approach the extended 1,200 N/mm² range.

FAQ

What materials can this end mill machine reliably?
This TECWERK end mill DIN 844 Type N (SKU 2000866384NW) is very well suited to steel and castings; non‑ferrous and stainless applications are possible but require adapted cutting data and, in many cases, a suitable coating.

Is the shank compatible with standard clamping systems?
Yes, the Weldon shank with a 12 mm diameter provides secure clamping in setscrew holders and compatible hydraulic or collet chucks, ensuring stability for the long version of this cutter.

How does the HSS‑Co8 grade affect tool life?
The HSS‑Co8 composition increases red‑hardness and wear resistance compared with standard HSS, so the TECWERK HSS‑Co8 cutter maintains cutting performance at elevated temperatures, extending tool life under comparable conditions.

Can this cutter reach deeper cavities without chatter?
The long Type N geometry combined with four flutes and the Weldon shank allows deeper reach while maintaining acceptable rigidity when properly clamped; correct feed, speed and machine stiffness remain essential to avoid chatter.

What cutting ranges are recommended for uncoated versus coated variants?
As supplied uncoated, the tool is geared for workpieces up to around 800 N/mm²; applying a suitable coating extends capability toward approximately 1,200 N/mm², permitting harder steels and more demanding operations.
