Bi-metal hole saw for metal Koelner/Rawlplug MN-61-413 35 mm
Bi-metal hole saw for metal Koelner/Rawlplug MN-61-413 35 mm
Bi-metal hole saw Koelner/Rawlplug MN-61-413, 35 mm diameter, is designed for making circular openings in metal materials. The tool combines high-speed steel teeth with a flexible steel body to balance cutting performance and resistance to deformation and heat. It fits most standard drill chucks and drill presses and is suitable for repetitive cutting of thin sheet metal, pipes and metal profiles during installation, repair and metalworking tasks.
The bi-metal construction provides increased durability and improved heat resistance compared with standard carbon-steel cutters, reducing wear during prolonged use. The saw’s teeth geometry is engineered to provide efficient chip removal and steady cutting speed, which helps achieve precise round holes with clean edges. Compatibility with hand drills and drill presses offers versatility for on-site and workshop use.
Secure the appropriate pilot drill or arbour in the hole saw if required, then mount the saw in a drill or drill press chuck and tighten firmly. Clamp the workpiece to prevent movement and align the saw with the intended cutting position. Start drilling at low speed to establish a center and then increase speed according to material thickness while applying steady, moderate feed pressure. Pause periodically for cooling when cutting thicker or harder metal to preserve the cutting edge and avoid overheating.
Use cutting lubricant when working with steel to reduce friction and extend tool life. Ensure the workpiece is firmly clamped and wear appropriate personal protective equipment such as safety glasses and gloves. Replace the hole saw if teeth become blunt or damaged to maintain cutting quality and safety.
