I've had a Greenlee 830Q quick change hole saw set for about 5 years an loved it. But recently some part of the arbor became bent, causing the pilot bit to wobble, and the hole saws to wobble around the pilot bit, resulting in larger-than-intended holes. This is a big problem if you intend to install a plastic bushing in the hole - the bushing won't stay in place if the hole is too big. After confirming with Greenlee that the warranty had expired, I decided to purchase a replacement arbor, but with a larger shank, in the hopes of avoiding a repeat of this problem. Unfortunately, the replacement exhibits a similar wobble. For anyone thinking the problem is clearly with my drill... it's not. Both arbors exhibit the same wobble in 6 different drills - 4 of which are owned by me. Additionally, the pilot bit from each arbor spin true when removed from the arbor and installed directly in the drill chuck. The same goes for other bits - they all spin true.
