Mikki 200 Series delivers unprecedented accuracy and repeated reliability in speeding the removal of broken exhaust manifold mounting bolts in General Motors 2.8L, 3.5L, 3.7L, and 4.2L inline engines. Mikki delivers speed, efficiency and utmost accuracy in drilling and subsequent assistance in the removal of the remaining portion of a damaged exhaust manifold mounting stud. There's no need to use a center punch to mark the damaged stud. Since it can be mounted in any of eight orientations, accessing every single stud, the instrument is both versatile and universal. Mikki features two press fit hardened steel Rc62 for life drill bushings. This unique feature allows for piloting the drill precisely on the center and at right angles to the damaged stud.
