Here’s a look at some of my most useful and most used accessories that I keep on my plumbing & heating service van.
2-9/16″ Switchblade self-feed bit 48-25-5150
12pc Hole Dozer w/ Carbide teeth hole saw kit 49-22-3090
7pc BIG HAWG w/ Carbide teeth hole saw kit 49-56-9280
5pc Carbide Multi-material dril bit set 48-20-8898

Of course there are so many tools and accessories every plumber must have but these are a start for hole drilling and cutting.
