●[For users inserting this product into an Impact Driver or drill driver] The hex shank of this product is a Japanese specification, with a longer distance from the insertion end to the retaining groove. In American and European specification Impact Drivers with a short anvil (insertion section), the bit may not lock securely in place and may come out. In that case, attach a Japanese-specification drill chuck (bit adapter) to the Impact Driver and insert this product into it. It can then be used without coming out.
