toy not a tool also deceptive product description [SEP] absolutely terrible read the description carefully all the lists of accessories are for a kit which this is not reviews all show a kit so it appears the seller has switched the product to an inferior item after getting good reviews for a larger kit with a different handpiece many of the shanks are not which requires a collet change and half the time i couldn t even get the spindle lock to work very underpowered and the grinding burrs are dull a worn out nail file is more effective sending it back
