The hole saw alloy teeth are made of high-strength tungsten-cobalt alloy and have a sharper shape design. Hole saws have better hole opening efficiency.
The surface of the carbid hole saw is smooth: the waste is easier to remove when opening, and the operation is more stable and the opening effect is better.
It can be used to open self leveling concrete, hollow brick, cement wall, concrete wall, red brick etc. when installing air conditioners, water pipes, water heaters, fume pipes, sewers, etc.
The concrete drill bit adopts a cross type, which is more stable and not easy to slip when drilling, and the high quality masonry drill bit is applicable to masonry wall, brick walls, cement boards and so on.
The core drill arbor of the hole saw is designed with SDS PLUS 300mm and SDS MAX 300mm, which are perfectly matched with the round shank four-hole and five-hole electric impact drills respectively. The length can meet the drilling requirements of most wall thicknesses.
