Adjustable hole saw, adjustable drill bit 30-120 mm for drilling holes in wood, plastic and plaster

Versatile Use - The wood hole saw allows you to drill through plywood, wood, plasterboard, acrylic, fiber cement panels, etc. Adjustable Diameter - The adjustable hole saw is capable of drilling large diameter holes (from 30 mm to 120 mm) for mounting spotlights or recessed speakers, for example. Material - The adjustable bit is made of chrome vanadium steel, which is corrosion-resistant, impact-resistant, deformation-resistant, and reusable after sharpening. Advantage - This tool offers a real advantage in terms of adjusting the drilling diameter, thus avoiding the accumulation of hole saws. Note - Before drilling, ensure that both styli are set to the same diameter and that the initial rotation speed is not high.
