Review on 🔍 Bosch HB425 4-in-1 Bi-Metal Hole Saw by Chris Smotherman

Ideal for installing 4" lights in the kitchen. FYI this does NOT come with a center drill or thread adapter. You will need to purchase it separately or use it from another crown (like me). Very sharp, very durable Went through 3/4" drywall and 1/2" wood paneling like butter with minimal cracking and chipping. Would buy Bosch bits again!
