Kent-Moore Porta-Tool PT-2210-A is designed for cleaning up and recutting counterbore ledges when shims are required to obtain correct liner protrusion. The exclusive double depth set collars with .001 inch graduations allow for quick and accurate adjustment settings. When two or more counterbores require cutting, a depth set spacer block is used to ensure all counterbores are cut to exactly the same depth.
Counterbore depth measurement can be made with PT-5025 Dial Dept Gauge and Extension, with the counterbore tool mounted in palce on the block. The low profile design allows repairs in frame, saving time and money (need to order cutter plate separately).
