• The recessed shape enables faster chip discharge, improved drilling speed, and reduced friction.
• For drilling concrete, blocks, mortar, stone, etc.
• The performance against reinforcing steel is also improved, and in case of contact with reinforcing steel, the sharpness is improved compared to conventional products (However, please do not perforate the reinforcing steel as it may cause chip chipping.).
• Can easily penetrate deck plates and concrete (The deck plate is slippery, so please touch the blade to the plate before turning on the power tool.).
