Made from strong, wear-resistant steel for heavy-duty use. Reams various hole sizes (both metric and imperial) and works with most power drills (thanks to the universal hex shank). T-handle design provides a secure grip and extra control for clean, round holes. Creates tapered holes, chamfers edges, countersinks for screws, and removes burrs from pipes and tubes. Perfect for woodworking tasks like shaping tops, chamfering edges, and drilling precise screw holes in instruments like guitars., Manufacturer: OKODOKO
