---------------------------------------------------------------------- 【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. ---------------------------------------------------------------------- Size: 4 to 30 mm (2 mm width from 4 to 22, 1 mm width from 24 to 30) Shank: Hexagonal shaft 6.35mm Compatible motors: rechargeable drills, impact drills, electric drills Applicable plate thickness: iron plate 2.0mm/stainless steel plate 1.6mm Material: Cobalt high speed steel, titanium nitride aluminum coating
