VA circular saw blades medium 250X2 mm

Description

Version: Precision toothing and very fine ground side faces. Rake angle especially for stainless steels. Nitrided surface: Hard, durable protection against edge build-up. Tooth form: 250 – 275 mm ? = BW 300 – 350 mm ? = HZ. Application: Tooth pitch t: • 3 mm – For thin pipes, profiles, sheet metal with 1 – 2 mm wall thickness. • 4 mm – For pipes, profiles, sheet metal with 1.5 – 4 mm wall thickness. • 6 mm – For pipes, profiles, and solid material with more than 4 mm wall thickness or cross sections up to maximum 50 mm. • 8 mm – For solid material more than 50 mm. Suitable for: • 37 m/min cutting speed (vc) in general structural steels up to 500 N/mm2. • 22 m/min cutting speed (vc) in unalloyed quenched and tempered steels up to 750 N/mm2, unalloyed case-hardening steels up to 750 N/mm2, nitriding steels up to 750 N/mm2. • 20 m/min cutting speed (vc) in unalloyed quenched and tempered steels up to 900 N/mm2, unalloyed case-hardened steels up to 900 N/mm2, nitriding steels up to 900 N/mm2, tool steels up to 900 N/mm2. • 15 m/min cutting speed (vc) in alloyed quenched and tempered steels up to 1100 N/mm2, alloyed case-hardened steels up to 1100 N/mm2, alloyed tool steels up to 1100 N/mm2. • 11 m/min cutting speed (vc) in sulphuretted stainless steels up to 700 N/mm2, austenitic stainless steels up to 850 N/mm2. • 11 m/min cutting speed (vc) in stainless and acid-free steels martensitic / ferritic up to 1100 N/mm2. • 15 m/min cutting speed (vc) in Ti-based superalloys up to 1200 N/mm2, special alloys up to 1200 N/mm2. • 27 m/min cutting speed (vc) in cast iron, spheroidal graphite cast iron, tempered cast iron. • Free cutting steels, free cutting stainless steels, aluminium and non-ferrous metals. • Applicable with emulsion with at least 4 % grease content (for tapping at least 8 %). Note: • For optimum performance and tool life use coolant concentrate No. 084260. • The concentricity and axial run-out values are considerably better than the figures in DIN 1840, in some cases by up to 50 %.
