Hobby-masonry drill bits for use in ordinary impact/hammer drills (with three-jaw chuck). For assembly of Easy, Light and Medium Kits in masonry, soft natural stone, and similar materials. Conditionally suitable for concrete without reinforcement... drilling in smaller diameter is then recommended. In hollow brick, aerated (cellular) concrete, and possibly also in 'normal' brick-- use without percussion setting. Not for wood. The cleaning of holes with a hole brush and blower allows for higher adhesive forces and is essential for professional bonding with composite mortar. Please refer as needed to the general information on percussion drilling.
