wolfcraft GmbH 5950000, 1 styck, Europa

The hole enlarging tool from wolfcraft is the first safe standard solution for neat and centred enlarging of existing boreholes using a hole saw. The clever innovation consists of a high-quality, conical plastic cylinder that you screw into the existing borehole with ease using the integrated thread. In the centre of the hole enlarging tool is a steel bushing that receives the centring drill bit with Ø 6–8 mm, enabling it to guide the hole saw safely. The hole enlarging tool also guarantees centred alignment with the existing borehole. This enables you to maintain an even hole pattern when drilling series of holes, e.g. when upgrading halogen ceiling spots to a larger LED system. The insertion aid supplied lets you tighten the fit in the borehole once more so that the hole enlarging tool is securely fixed in the borehole. Simply position the hole saw, drill the hole and then remove the hole enlarging tool together with the drilling core. The hole enlarging tool also makes working overhead child's play.
