Schaftfräser DIN 844 Type N, 8 mm, HSS‑Co8 — short 4‑flute end mill by TECWERK

The Schaftfräser DIN 844 Type N, 8 mm HSS‑Co8 is a short, centre‑cut end mill designed for rigid milling and plunge work in workshop and industrial settings.

• HSS‑Co8 for improved heat resistance
• DIN 844 Type N short 4‑flute design
• Weldon shank with drive flat for secure clamp
• Centre‑cut for plunge and slotting operations

Stable cutting performance for demanding steel machining

The short 4‑flute geometry, manufactured from HSS‑Co8, provides a reliable balance between wear resistance and toughness for interrupted cuts. With an 8 mm cutter diameter and 4 mm cutting length, the tool concentrates stiffness close to the cutting zone, reducing deflection and chatter during heavy engagement. The centre‑cut feature permits controlled plunging and slotting without pre‑drilling, while the 4‑flute layout optimises surface finish on side walls. Performance guidance indicates suitability up to 800 N/mm² in uncoated condition and, where a suitable coating is applied, material strength limits can be extended toward 1000 N/mm² — crucial information when setting feeds and speeds.

Secure clamping and dimensional control for repeatable setups

Clamping reliability is provided by the Weldon shank with drive flat on a 10 mm shank diameter, paired with a compact 69 mm overall length and 25 mm effective length. This configuration minimises overhang and improves run‑out stability in collets or chucks, translating into consistent part accuracy and longer tool life. The short design also simplifies fixture planning in small machining centres or compact rigs. The tool’s ground relief (approx. 7.5 mm) contributes to predictable chip flow and reduced rubbing at the flank, which helps maintain dimensional control across serial runs.

Broad workshop applicability with clear material recommendations

Designed to the DIN 844 Type N specification, this end mill is primarily engineered for conventional steels and cast iron where it is very well suited, while performance on stainless and non‑ferrous alloys is conditional and depends on cutting data and part geometry. The cutter is right‑hand cutting, making it compatible with standard milling strategies. For marginal materials or complex alloys, pairing the substrate with an appropriate coating and adapted cutting parameters can extend tool capability.

FAQ

What applications is this TECWERK Schaftfräser best suited for?
This TECWERK Schaftfräser (DIN 844 Type N, SKU 2000866330NW) is best suited for rigid milling operations in steel and cast iron, including slotting and plunge cuts where stiffness and tool life are priorities.

Can the end mill be used for stainless steel and aluminium?
The tool can machine stainless steel and non‑ferrous metals conditionally; optimised cutting data and, where appropriate, a compatible coating are recommended to improve performance on these materials.

What does HSS‑Co8 mean for tool behaviour?
HSS‑Co8 indicates a cobalt‑alloyed high‑speed steel that offers improved hot hardness and toughness compared with standard HSS, benefiting the TECWERK end mill during higher temperatures and intermittent cutting.

Is the Weldon shank compatible with standard clamping systems?
Yes, the Weldon shank with drive flat provides secure clamping in common toolholders and chucks, improving resistance to rotation and enhancing repeatability in production setups.

Does the cutter allow plunging without pre‑drilling?
Yes, the centre‑cut design permits controlled plunging and makes the cutter suitable for short plunge operations and slotting in appropriate materials.
