The hole saw set features double metal holes with high-quality M42 material, ensuring durability and preventing the teeth from falling off.

This versatile kit is suitable for various opening operations, such as plate holes, home wood, galvanized pipes, fire pipes, plastic, and gypsum board. It can be used with pistol drills, bench drills, vertical drilling machines, and more. The precision of the concentric degree ensures uniform teeth edge, extending the life of the hole.

The set includes 9 M42 drilling hole saws in sizes ranging from 16mm to 38mm (5/8-Inch to 1-1/2-Inch). Each hole saw drill bit is individually packaged for easy carrying and finding the required specifications.

Made of M42 HSS steel and BI metal, the hole saw set offers sharp blades with high hardness, strong wear resistance, and a long service life. It provides a smooth and fast cutting experience with little vibration and improved removal speed of cylindrical iron filler in the hole. The pressurized spring makes chip evacuation easier, and the hole saw kit can be quickly balanced for stable operation.

To ensure the longevity of the hole saw set, it is important to keep the drill stable during use. It is recommended to start drilling with a slow rotary speed to prevent the centre bit from getting snapped, especially with larger hole saw sizes. Additionally, the use of cutting fluid is suggested to keep the hole saw cold during usage and prevent overheating, damage, or burning. It is important to note that the hole saw set is not recommended for use on hard wood, hard metal, and stone.
