Drilling in a wide variety of work materials. Boring a hole through a composite wall containing heat insulating materials - with one thrust.

• The diamond grains at the cutting teeth provide smooth drilling.
• Small chance of bit binding ensures safe work.
• Drilling in a wide variety of work materials.
• Cutting lightweight steel beams for ceiling is absolutely easy.
• The heat insulating materials are not entangled with the cutter during drilling.

• Composite walls that contain heat insulating materials.
• Piping work for air conditioners, water system, and electrical systems.
• Mortar, block, brick, ALC, Japanese walls, plaster and lath walls, ceramic/metallic siding boards, etc.
• Smooth drilling in PVC rib pipes, FRPM pipes, etc. without bit binding.
