About This ??Bi-Metal Hole Saw Size --- Cutting Diameter: 170mm/6-45/84inch; Cutting Depth: 37mm/1.46inch; Overall Length: 94mm/3.7inch; Shank Diameter: 9.5mm/0.37inch ??Wide Applications --- Designed for versatility, bimetal hole saw is suitable for cutting holes in various materials, including wood, metal, plastic, and more. It is commonly used in construction, electrical installations, plumbing, and other applications that require precise and efficient hole cutting. ??Ease of Use --- To use, attach the hole saw to a compatible drill or hole saw arbor. Apply moderate pressure and rotate in a slow and steady manner, allowing the teeth to gradually penetrate and cut through the material. Use cooling lubricant when cutting metal to reduce heat buildup. ??High Speed Steel --- The center drill material of the hole saw is made of high-speed steel (HSS), which has high hardness, heat resistance, wear resistance, and impact resistance. ??Useful Tips --- When using our bimetal hole saw, always wear appropriate safety gear, such as safety glasses, gloves, and a dust mask, to protect yourself from potential hazards. Ensure that the hole saw is securely attached to the drilling equipment before operation. Take breaks during prolonged use to prevent overheating of the hole saw and maintain its cutting efficiency.
