## Long description

Key specifications
Overall length: 400 mm
Tip material: carbide masonry tip designed for rotary and percussion use
Pack quantity: single piece
Primary application materials: concrete, masonry, natural and artificial stone, brick
Intended use: long-reach masonry drilling in construction and repair
How to use
Fit the drill bit securely into a compatible drill chuck or SDS adapter according to the drill manufacturer’s instructions. Select the appropriate rotary or rotary-percussion mode depending on the material and drilling depth. Begin at low speed to establish a precise start point, then increase speed and apply steady, even pressure while allowing the drill to do the work. Periodically withdraw the bit to clear dust and debris, which helps maintain cutting efficiency and prevents binding. Use appropriate personal protective equipment, including eye protection, gloves, and hearing protection.
Usage recommendations
For prolonged bit life and best results, match drill mode and speed to the material: use rotary-percussion for concrete and masonry, rotary-only for softer stone where percussion may cause chipping. Keep the bit straight and avoid excessive lateral force. When drilling deep holes, withdraw the bit regularly to remove cuttings and reduce heat buildup. Ensure the drill and bit are compatible in shank type and size before use.
