4-1/2″ Diameter Diamond Carbide Core Drill. The perfect size for radon mitigation work. Cuts hundreds of holes in high strength and HPC concrete. This system works great for confined areas. Also no water is needed when using this concrete coring system.Part of the NEW Ratio Bit System.
Requires the Starter Pilot Bit. First step is to know what type of rotary hammer you want to use this in. Simply purchase the adapter. Either SDS-PLUS, SDS-MAX or SPLINE Drive. If you don’t want to bend over, I recommend either a 11″ extension or an 18″ extension. The beautiful thing about this set up is you only need to purchase the adapter, extension and pilot bit one time. Maybe an additional pilot bit down the road but that’s it. Premium micro-grain diamond carbide for super fast dry coring of concrete, cement, asphalt, brick, block and all lapidary. Great for soil testing, radon mitigation and professional applications. The best dry coring bit in it’s class. Made in Germany.
