It allows you to hold a square shanked tap from 5.5mm ( a 1\/4 UNF \/ UNC tap has approximately this size shank and fits easily) to 12mm ( I tried a  5\/8 - 11 tap and it had the maximum size shank it would hold)  securely and use your 1\/2\" drive ratchet to drive it. For hard to reach areas an extension can be added to the back of the tap chuck. It can also be used with a sliding T handle . \u003c\/h3\u003e\n\u003ch3\u003eA very useful tool that makes difficult jobs much easier.\u003c\/h3\u003e\n\u003ch3\u003ePremium Japanese quality! \u003c\/h3\u003e","brand":"Koken","offers":[{"title":"Default Title","offer_id":46846779457732,"sku":null,"price":136.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0565\/1778\/7844\/files\/IMG_2011_2d53847d-dbd6-4176-ba40-51c9c7e8a7a4.jpg?v=1790345621","url":"https:\/\/cardontools.com\/products\/koken-no-3-made-in-japan-1-2-drive-tap-holding-chuck-holds-5-5-12mm-range-square-shanks-4131a","provider":"Cardon Tools","version":"1.0","type":"link"}
