HELITANG T490 Heavy Duty Face Mill Line

The T490 FLN-22ST 90° face milling tools were designed mainly for machining of large-size parts in heavy cutting conditions, especially in cases when the configuration of a machined workpiece or workholding constraints require milling near to shoulders.

The tools carry tangentially clamped inserts T490 LNHT 22… with 4 helical cutting edges that are mounted in the pockets with seats protecting the tool body even in case of insert breakage. The major application of these durable tools is heavy duty milling steel, stainless steel and cast iron with depth of cut up to 21 mm.
