• 【High quality tungsten carbide】This hole saw kit is made of tungsten steel and tungsten carbide, with high tensile strength. It is very hard and has excellent wear resistance, making it valuable in cutting tools, drills, and abrasives. Even in corrosive environments, it has strong corrosion resistance.
• 【Multiple application scenarios】It is easy to drill holes in walls, stones, bricks, or install pipes such as air conditioners, range hoods, and sewers. Due to the difference in hardness between stones/bricks, hole saws require more time than normal. When processing high hardness materials, please use them in flowing water to reduce the wear of the hole saw.
• 【Supporting tools to improve work quality】 Equipped with 5 dust collection bags to help reduce dust during chainsaw operation. This set offers three different connecting rods: 110mm&300mm SDS Plus, 300mm SDS Max, and a convenient adapter for different devices.
• 【Tool usage suggestions】 This kit is equipped with a convenient adapter. The previous version was fixed with screws, which made it easy to get stuck during use. This newly upgraded connector can quickly and easily install and remove the centering drill bit without any deviation during operation. The connector should be placed inside a product with a diameter of 110mm. When in use, it is easy to see when picked up. After installing the connector, you can choose to install or not install the screws on the connecting rod. After connecting the connector, insert the center drill bit and rotate it until you hear a "click" sound. Please tighten before use.
• 【Suggested usage techniques】※ If you want to disassemble the centering drill, you can hold down the switch of the centering drill fixture and keep the switch in the pressed state. The centering drill can be easily disassembled.
