I recently purchased two Dewalt D25501K Hammer Drills. I need bits. In pest control doing termite treatments, we need to drill 1/2 inch holes through concrete slabs. In the past I have used drills that have had "spline" drives. These Dewalts don't, so I am uneducated on what bits I need. I know I need 1/2 inch in diameter and at least 16 inches or so cutting depth, but I'm not sure if my new drills require a certain kind of SDS bit. I see SDS MAX, SDS PLUS and just SDS. Can you tell me what my drills can and will use so I know what to buy?
It's described as SDS MAX and Spline combination.
This question/answer imply that your choices are... SDS MAX and Spline. SDS MAX is incompatible with (and much larger than) the other SDS types.
