---------------------------------------------------------------------- 【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 4 mm) ●Step width (mm): 4●Number of steps (steps): 14●Shank diameter (mm): 10●Drilling dimensions (φmm): 4, 6, 8, 10, 12, 14, 16, 18, 20, 22, 24, 26, 28, 30●Overall length (mm): 100 ●Non-coating ●Cobalt high speed steel
