Intended to aid the fitting of down lights and ceiling loudspeakers, these high quality adjustable radius cutters are used in conjunction with variable speed hand power drills or drill presses to quickly cut apertures from 30mm to 260mm diameter in plywood, plasterboard, acrylic-plastic or similar sheeting. Depth of cut is 23mm, so material thicknesses of up to 45mm are accommodated if both sides can be accessed.
A sprung, transparent cowl aids positioning normal to the surface to be cut and catches the debris produced by the cutter. The blade holder and bit secure the cut section when free.
The outfit is supplied, in a moulded carrying case and comes complete with a spare wood blade, spanner, hex key and counterbalance weights.
