This 3/4 inch by 16 inch like new drill bit is great for use in any Quality rotary hammer percussion drill that uses the SDS Drive or SDS PLUS Drive system. Bosch, Makita, Hilti, Milwaukee and Dewalt all use this system in there small to medium size drills . They will NOT work in drills that have the SPLINE Drive or SDS MAX Drive systems. Nor will they work in really cheaply made hammer drills that use standard round drive masonary bits. Be sure your drill either says SDS or SDS PLUS!! The drill bit is carbide tipped for long life and will work in concrete or masonry applications. Check pictures for proper configuration
and part number.
