Cut New Or Recut Old Slots; The Right Way
High-quality, steel files designed for one purpose only – to cut perfectly square screw slots every time. #7, #9, and #11 files cover the most common slot sizes. Smooth-sided to cut only on the edge. Will not widen the slot as it deepens, or damage the screw head. Cleans up marred slots on hard to replace screws or cuts slots in new screws. Use with Needle File Handles. These files are very thin for precise cutting. Sorry, cannot guarantee against bending or breakage. Sold individually or as a set.
