roughing boring head / double-edged
BIG KAISER Precision Tooling Ltd.
Min.: 16 mm
Max.: 21 mm
Based on KAISER's existing 319 SW series, the MW Boring Head is a twin-cutter boring tool, which means it can quickly remove large quantities of material, compared to single-cutter tools. The MW's two cutting edges can be pre-set independently to the required diameter, with a tolerance of 0.2mm.
The MW Boring Head is ideally suited to semi-finish or finish boring operations of workpieces with die cast holes. It uses a 20mm shank, which means it is easy to clamp in commonly-used milling chucks and tool holders.
Its precision serrated connecting system ensures secure and rigid connection, and means that torque can be maximised. In aluminium, cutting speeds of up to 280mm per minute can be achieved, with a feed rate of 0.3mm per revolution and a cutting depth of 4mm.
A spiral groove improves chip evacuation. Coolant is provided directly to the cutting edges, and in blind hole boring, coolant is routed through the centre of the tool, which further helps in chip evacuation. The coolant hole can be closed when required using a stop screw.
