wolfcraft GmbH 5953000, 3 stk., Europa

The three-piece hole enlarging tool set from wolfcraft is the first safe standard solution for neat and centred enlarging of existing boreholes using a hole saw. The high-quality two-component case contains three hole enlarging tools: the hole enlarging tool for existing hole dimensions of Ø 35–51 mm can be used with hole saws from Ø 60 mm, the tool for existing hole dimensions of Ø 46–62 mm with hole saws from Ø 68 mm and the tool for existing hole dimensions of Ø 54–70 mm with hole saws from Ø 76 mm. The set also contains an insertion aid as well as three steel drilling bushes with Ø 6, 8 and 10 mm that can be installed to suit the diameter of your 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 or 10 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. With this set you are prepared for existing boreholes of Ø 35–70 mm – ideal for professional use. 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.
