Hole saw Cimco 207564 bi-metal HSS 68 mm for drilling large diameter holes

Bi-metal HSS hole saw Cimco 207564 with a 68 mm cutting diameter, designed for cutting larger holes in metal and other materials. The tool pairs high-speed steel cutting teeth with a flexible backing to provide wear resistance and improved heat tolerance, making it suitable for repeated use in demanding drilling tasks with handheld drills or drill presses.

Advantages

The carbide-edge high-speed steel teeth and bi-metal construction increase durability and resist tooth breakage during aggressive cutting. The flexible backing reduces the risk of blade fracture and extends service life. The saw is compatible with standard arbors and is suitable for use with drill chucks and drill presses for consistent hole quality.

How to use

Fit the hole saw onto a compatible arbor or mandrel and secure it in the drill chuck. Mark the hole centre, clamp the workpiece if possible, and start drilling at low speed to create a pilot indentation. Increase speed and apply steady pressure, allowing the saw to cut without excessive force. Periodically withdraw the saw to clear chips and reduce heat. After cutting, finish the hole edges as required.

Recommendations

Use cutting lubricant when working with steel to reduce heat and extend blade life. For safety and accuracy, secure the workpiece, wear eye protection, and avoid excessive feed rates that can overload the saw.
