The search for a powerful, process-safe and high quality shoulder milling system is over. With the new double-sided 90 milling system 4910 WNT presents a unique system providing a precise 90 profile with 8 usable cutting edges per insert. Maximum efficiency guaranteed when shoulder milling. Hard wearing nickel plated body Narrow and wide pocket Easy handling with a large insert Exact 90 Profile Irregular pitch for quiet machining Field test reports Cutter Ø: 63 mm Material: 36CrNiMo4 v c : 150 m/min a e : 6 20 mm f z 0,13 0, % a p % Chip volume, Q cm 3 /min % Number of finished 2 components % WNT Competitor 2

3 Dragonskin technology with 8 cutting edges for maximum economy Introduction With these extremely stable inserts the highest cutting data is possible, very smooth running even with less powerful machines and thin walled components. Very high efficiency with 8 usable cutting edges Exact 90 no programming adjustment necessary Maximum process reliability due to the extremely stable insert Maximum tool life due to the stable insert location positioning and Dragonskin coating New Dragonskin Coating Precision ground insert for perfect axial and radial run-out accuracy Dragonskin the correct Dragon for every material type In combination with the Dragonskin coating system 4910 is not only extremely hard-wearing, but also provides a maximum performance and process reliability. the first choice for machining non, low and high alloyed steels The first choice for the machining of ductile and malleable irons and sintered steels The first choice for machining austenitic, ferritic and martensitic stainless steels Cutter Ø: 50 mm Material: 16MnCr5 a p : 3.5 mm a e : 35 mm Advantages/Benefits v c in m/min f z Chip volume, Q cm 3 /min Usable cutting edges 220 0, % 0, % % + 88% Very high metal removal rates Maximum service life 8 usable cutting edges per insert at exact 90 Highest cutting data Soft cutting action through positive chip breakers Low power consumption Universal application in various materials WNT Competitor 3
