Schaftfräser DIN 844 Typ NR Ø25 mm, cutting length 63 mm — TECWERK

The Schaftfräser DIN 844 Typ NR Ø25 mm Einsatz‑L.63mm HSS‑Co5 TiCN Weldon TW is a short multi‑flute HSS end mill designed for demanding milling of steel and cast iron in workshop and industrial environments.

• HSS‑Co5 for improved hot hardness
• TiCN coating for extended tool life
• Cylindrical shank with Weldon flat
• Very good for steel and cast iron

High‑performance cutting that boosts productivity

The short multi‑flute geometry delivers stable engagement and a consistent surface finish while the HSS‑Co5 composition provides enhanced red hardness compared with standard high‑speed steel. The addition of a TiCN coating reduces friction and increases resistance to abrasive wear, which together extend the tool life under elevated cutting temperatures. For applications where repeatability and uptime matter, this configuration offers a robust balance of toughness and hardness, minimising rework and supporting smoother production cycles.

Secure clamping and predictable chip control to reduce downtime

A Weldon shank with drive flat and the relieved core profile improve tool retention and reduce slippage in the holder, so clamping reliability is enhanced during interrupted cuts. The short multi‑flute arrangement and the centre cut enable axial penetration when plunging, while the 45° chamfer on the cutting edge supports controlled chip formation. These design choices mean fewer interruptions for tool changes and predictable tool behaviour, leading to lower secondary costs and less unscheduled maintenance.

Clear material guidance and machining suitability

The cutter follows DIN 844 specifications and is optimised for machining materials with low to medium tensile strength: uncoated performance is rated up to 800 N/mm², while the TiCN coating permits use up to 1000 N/mm² where appropriate. Suitability is very good for steel and cast iron, and conditional for non‑ferrous metals, stainless steels and special alloys; selection should reflect the workpiece alloy and machining strategy. When combined with appropriate feeds and moderate cutting speeds, this tool offers reliable removal rates and surface integrity for general workshop and production tasks.

FAQ

What materials is this end mill best suited for?
The TECWERK end mill is very well suited for steel and cast iron and can be used conditionally for non‑ferrous metals, stainless steels and certain special alloys depending on the machining parameters.

Does the TiCN coating improve performance compared with an uncoated cutter?
Yes, the TiCN coating on the HSS‑Co5 core reduces friction and increases abrasive wear resistance, which typically extends the service life compared with an uncoated tool under similar cutting conditions.

Can the cutter be used in standard Weldon holders?
The tool features a cylindrical shank with a Weldon drive flat, so it is compatible with standard Weldon holders and provides secure clamping for interrupted cuts.

What does the designation DIN 844 Type NR mean for the application?
DIN 844 Type NR indicates a standardised short multi‑flute end mill geometry suitable for general milling tasks; in this case it supports centre cutting and axial entry where required.

Is this cutter suitable for plunging and slotting operations?
The centre cut design allows axial penetration and controlled plunging, while the short multi‑flute geometry supports slotting with good surface finish in recommended material ranges.
