Core drill bit with extension plus 120mm / 50mm

Note: Please select the desired SDS-Plus shank/extension for each core drill bit (centering drill bit included with every shank). If you only need the core drill bit, please select "without shank" for the core drill bit. Selecting the impact core drill bit: Choose the appropriate impact core drill bit for the respective material and the desired hole diameter. Pay attention to the quality and specifications of the drill bit to ensure it is suitable for your drill. Compatibility: Make sure the impact core drill bit is compatible with your drill. Most impact core drill bits are designed for SDS-plus or SDS-max chucks. Check the chuck interface of your drill. Mounting: Mount the impact core drill bit securely and firmly on the drill. Check that the bit is correctly and stably fastened to prevent slipping or loosening during operation. Drilling speed: Select the correct speed and impact rate for the respective material. Start with a low speed to start drilling into the workpiece, then increase the speed once the bit is properly seated. Drilling: Place the impact core drill bit straight onto the workpiece and apply even pressure. Let the impact function of the drill do the work and avoid excessive pressure to prevent jamming or damaging the bit. Drill in intervals and regularly withdraw the bit to remove drilling dust and cool the drilling site. Cooling and lubrication: For longer drilling operations or very hard materials, cooling may be necessary. If required, use water or a special coolant to reduce friction and heat generation. Safety instructions Protective equipment: Always wear appropriate personal protective equipment, including safety glasses, hearing protection, a dust mask, and gloves, to prevent injuries from dust, chips, and sparks. Stable work environment: Ensure that the workpiece is securely fastened and does not move during drilling. If necessary, use a workbench or a vice for fixation. Hazard awareness: Pay attention to your surroundings and keep clear of rotating parts. Always switch off the drill before making adjustments or changing the impact core drill bit. Ventilation: Work in a well-ventilated area to minimize exposure to dust and fumes. Use an extraction device if necessary. Maintenance tips Cleaning: Clean the impact core drill bit after each use with a cloth or brush to remove dust and residue. Avoid aggressive cleaning agents that could damage the bit. Inspection: Regularly inspect the impact core drill bit for wear, cracks, and other damage. Replace damaged or heavily worn bits to ensure precise and safe drilling results. Storage: Store the impact core drill bit in a dry place, preferably in a protective case or tool box, to protect it from moisture and damage. Sharpening: Have dull impact core drill bits professionally sharpened or replace them to maintain drilling performance. By following these instructions and tips, you can extend the lifespan of your impact core drill bits and ensure that you work effectively and safely.
