The hand piece can be held in the hand like a bat, or at the fingertips like a pencil, so very versatile. Changing tools is a split second, flip the lever, pop in the tool and flick the lever back. Instant! So great when polishing and switching from one mop to another, or using the radial discs.As mentioned it uses 332 inch shanks, which is most of the pendant drill accessories you will see here. Likewise if you want to use it for drilling then you need mounted drill bits on a 332 shank. Since getting this hand piece I have quickly found it to become my main go to attachment, due to its speed in change. The Faro quality is first rate they are superbly built on the inside and out. I have stripped and rebuilt four old ones. Faro where very helpful and provided me with full schematics and a list of UK spare parts suppliers. Hence you can keep these going for a lifetime.Italian quality, The Ferrari of hand pieces.
