Key specifications
Brand: KWB
Model / MPN: 499439
EAN: 4009314994391
Diameter: 10.3 cm
Type: Single hole saw, tungsten carbide gritted
Package: Hanging card
How to use
Mount the hole saw on a compatible arbor and secure it to the drill according to the arbor manufacturer’s instructions. Mark the intended drilling position and start at low speed to create a guide groove, then increase speed and apply steady, even pressure. For hard or abrasive materials use intermittent drilling and, if applicable, cooling or lubrication to reduce heat. After cutting, remove debris and inspect the hole for burrs; finish as needed.
Usage recommendations
Use appropriate personal protective equipment (safety glasses, gloves and hearing protection) and select a drill with sufficient power and correct arbor fit. For brittle materials (tiles, ceramics, natural stone) consider using masking tape over the cut area to reduce chipping; for reinforced concrete avoid excessive pressure and use slower speeds.
