Hole-Drilling Working Materials
Ideal for stainless steel plates, steel plates, aluminum plates, PVC plates, FRP, enamel, stainless steel pipes, steel pipes and cast iron pipes up to 4.5mm thick and for ceramic sidings, metal-siding laminated boards and artificial marble up to 15mm thick.

Features

• Double-edged saws for tool diameters of between 21 and 55mm greatly reduce tool costs and achieve twice the cutting capacity of ordinary hole saws.
• l The clicking shank allows single-operation mounting and removing of units (tools) for easier tool replacement and chip removal. One shank adapts to all sizes (single edge for tool diameters of between 14 and 20mm).

Compatible Electric Drills
Electric drills and vibration drills with chucking capacities of 10 mm or largerOn a lightweight hammer drill (SDS type), be sure to use in the rotation mode.

Working Materials and Features
Previously, different working materials required different core drills. Our universal core drills are capable of drilling a wide variety materials (not including reinforced concrete) thanks to a newly-developed tool geometry and are suitable for drilling the materials as shown below:

On electric drills with chucking capacity of 13mm in the vibration mode:
Mortars, blocks, bricks

On electric drills with chucking capacity of 13mm in the rotation mode:
Ceramic sidings, metal sidings, ALC, galvanized steel plates, colored galvanized iron plates, wooden boards, ordinary plywood, bonded wood, slates, cement bonded particleboard, PVC plates, PVC pipes.

Easy Chip Removal and Wide Tips Combined with Center Drill:
This tool is provided with a few wide chips, which create gaps between the chips and the tool at the time of drilling. The center drill can be removed in a single operation, allowing easy removal of the chips.
