Terrible design slipping setscrew

The setscrew on the pilot bit kept slipping and could not be tightened enough to stay in place. Tried to counteract the slippers with tape and zip ties and nothing worked. Would not recommend this item to anyone at that price. After going through two layers of concrete block the core bit is spent. If you buy this plan on being annoyed with the pilot bit And only getting one use out of the core bit

Pros

The SDS Plus pilot bit adapter ensures precise drilling every time, allowing you to create perfectly-sized holes with ease

Cons

May not work well on brittle or fragile materials
