The Flex BHW812VV is a 2-Speed Electronic Wet Handled Core Drill. The drill has 13 Amp motor and infinitely adjustable speeds of 0-3800 RPM. The wet core drill is designed for drilling in concrete, natural stone (without hammer action) for electric boxes, fireplace connections, junction boxes and conduits. It is also ideal for precision drilling when securing heavy-load anchors. The nonhammering core drilling method allows for precise and fast drilling even in reinforced concrete. The Flex five-fold VV electronic control gives consistent speed control, soft start with acceleration trigger, overload protection, temperature monitoring and speed pre-selection. It features two-gear transmission for speed-compatible working. The additional rotating auxiliary handle with stops prevents turning. Not for use on masonry or asphalt.Please note that the hose assembly is NOT included in the BHW812VV. The hose is sold separately.
