Effort-Saving Ratcheting Operation The reversible ratcheting T-handle offers directional control and efficient torque transfer, allowing threading work with less effort than conventional tap wrenches. A 5 swing arc enables use in tight spaces, and the twist-lock guide system helps reduce die ?walk back,? keeping alignment centered during threading. Correct Drill Bit Pairing Included The set includes drill bits matched to the tap sizes, eliminating the need to reference charts or check drill-tap compatibility during work. This prevents sizing errors, increases threading accuracy, and improves workflow efficiency. Double-Layer Storage Case A structured storage box with two layers keeps accessories separated and protected. Assigned compartments ensure all taps, dies, drill bits, and ratcheting tools remain organized and easy to access. Notes This SAE/Metric tap and die set is designed for general purpose threading use, equal to ISO 3/2B tolerance grade, suitable for 6H nut class.
