Carbide hole saws have a smooth surface: scraps are easier to remove when drilling, smoother when drilling and better drilling results. The hole saw alloy teeth are made of high-strength tungsten-cobalt alloy with a sharper design. The hole saw has better drilling efficiency. The concrete drill bit is cross-shaped, which is more stable and prevents slipping when drilling. High quality masonry drill bits are suitable for brick walls, cement boards, etc. When installing air conditioners, water pipes, water heaters, flues, sewers, etc., it can be used for self-leveling concrete, hollow bricks, cement walls, concrete walls and red bricks, etc. The SDS-plus hole saw shank perfectly matches the round shank four-hole electric impact drill. The shaft length of the concrete hole saw is 220mm, which can meet the drilling thickness requirements of most walls.
