Core bit with extension Max 350mm / 220mm

Note: Please select the desired SDS-Max shank/extension for each core drill bit (centering drill bit included with each shank). If only the core drill bit is needed, please select "without shank" for the core drill bit. Selecting the Hammer Core Drill Bit: Choose the appropriate hammer core drill bit for the specific 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 hammer core drill bit is compatible with your drill. Most hammer core drill bits are designed for SDS-plus or SDS-max chucks. Check the chuck interface of your drill. Attachment: Mount the hammer core drill bit securely and firmly on the drill. Check that the bit is correctly and stably attached to prevent slipping or loosening during operation. Drilling Speed: Select the correct rotational speed and impact rate for the specific material. Start with a low speed to initiate drilling and then increase the speed once the bit is properly engaged. Drilling: Position the hammer core drill bit straight onto the workpiece and apply even pressure. Let the drill's hammer function 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 area. 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 hammer core drill bit. Ventilation: Work in a well-ventilated area to minimize exposure to dust and fumes. If necessary, use an extraction device. Maintenance Tips Cleaning: After each use, clean the hammer core drill bit with a cloth or brush to remove dust and residues. Avoid aggressive cleaning agents that could damage the bit. Inspection: Regularly inspect the hammer 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 hammer core drill bit in a dry place, preferably in a protective sleeve or tool case, to protect it from moisture and damage. Sharpening: Have dull hammer core drill bits professionally sharpened or replace them to maintain drilling performance. By following these instructions and tips, you can extend the life of your hammer core drill bits and ensure that you work effectively and safely.
