Pro File Guide with Sidewall Adapter Kit (round cutter) - choose from 91, 92, 93 or 94 degrees. This is a Pro file guide that comes with an easily attachable/detachable SAK (sidewall adapter kit) for removing the sidewall prior to filing. By simply attaching the kit with 2 screws, you have a Sidewall Removal Tool. 2 tools in one for those interested in saving money and space in their tuning kits! Comes with Round Carbide Cutter and 2 allen keys. Round cutters are typically used for 'cap' contruction skis and boards however, we feel they also work extremely well on 'sandwich' construction type skis and boards. Very universal.
