Shernbao Cordless Nail Grinder (USB Charger) This cordless nail grinder from Shernbao is perfect for salon use. The grinding wheel is made from super durable & water resistant carborundum and the unique motor maintains constant speed and RPM, regardless of the job. Two speeds allow for more customised grinding to suit different lengths and strengths of the nails. The grinder fully charges in 90minutes and runs for over 3 hours on a full charge, with an over-charging protection feature so you don't have to worry about leaving it on the charge too long. The smart LED display shows your charge level. With an extremely quiet motor, this will suit nervous pets. The wheel features a cover to stop you going too short, and can be removed for more confident groomers or large nails. ​ Cordless Highly durable carborundum grinder Two speed settings 90 minute full charge time 3 hour run time Quiet motor
