---------------------------------------------------------------------- 【Voltage Compatibility】 When using electrical appliances, please note that they are designed for Japanese voltage specifications (90-110V), so if you use them with a different voltage, it may cause a malfunction. 【Plug Type】 Our products use Japanese plug types (A or B type). Please use a conversion adapter if necessary. 【Important Note on Transformers and Adapters】 A transformer adjusts voltage to match your device’s requirements. A conversion adapter only changes the plug shape and does not adjust voltage. Using only a conversion adapter without a transformer may result in damage to the product. 【Liability】 We are not responsible for malfunctions or damages caused by improper use, such as operating the product without a transformer. ---------------------------------------------------------------------- ●Work material: iron plate, copper plate, stainless steel, aluminum, plastic (up to 4mm) ●Step width (mm): 4●Number of steps (steps): 9●Shank diameter (mm):●Shank diameter: 3/8●Drilling dimensions (φmm):●Drilling dimensions: 1/4, 5/16, 3/8, 7/16, 1/ 2, 9/16, 5/8, 11/16, 3/4●Shank diameter: 3/8●Drilling dimensions: 1/4, 5/16, 3/8, 7/16, 1/2, 9/16, 5/8, 11/16, 3/4 ●Surface treatment: Titanium coating ●High speed steel
