{"product_id":"bottom-bracket-tap-cutters-ita","title":"Bottom Bracket Tap Cutters ITA","description":"\u003cp\u003eItalian-threaded BB shells (36 × 24) live mostly on Italian heritage frames (Colnago, De Rosa, Bianchi, older Pinarello road frames) and on a small set of premium builds that adopted the standard for character reasons. The 1697.1 Italian tap cutters are the matched replacement \/ kit-conversion pair for chasing those threads cleanly. The cutting teeth are sized to M36 × 1.058 mm (24 TPI), and a single pair handles both sides of the shell.\u003c\/p\u003e\n\u003ch2\u003eWhat this piece does\u003c\/h2\u003e\n\u003cp\u003eItalian BB shells differ from BSA in one workflow-relevant way: both sides of the shell are right-hand thread. The non-drive and drive sides both back off counterclockwise from their respective ends; both taps turn the same way in. The 1697.1 Italian cutter pair is sized to that thread and goes into the Italian tap holders (1697.2\/4 ITA), which sit on the modular handles like the rest of the frame-prep family.\u003c\/p\u003e\n\u003ch2\u003eUse cases\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eReplacement.\u003c\/strong\u003e When an existing Italian cutter pair has lost its working edge.

The Italian thread is a smaller fraction of the catalog's BB-prep volume than BSA, but a shop that services Italian heritage road frames needs the correct cutters regardless of frequency; carrying the variant is the difference between accepting that work and turning it away.\u003c\/p\u003e\n\u003ch2\u003ePro tip from our mechanics\u003c\/h2\u003e\n\u003cp\u003eThe both-sides-right-hand pattern is where mechanics trained on BSA most commonly misstep. There is no left-hand tap to worry about, and the muscle memory of “drive-side cuts counterclockwise from the drive side” does not apply. Both taps turn clockwise into the shell from their respective ends. If a mechanic is alternating between BSA and Italian work, slowing down to verify the thread standard on the frame before mounting cutters into holders saves a galled shell.\u003c\/p\u003e\n\u003cp\u003eItalian BB shells also tend to need less aggressive paint-film clearing than BSA on factory carbon frames; many Italian heritage frames are steel with thinner thread-protection paint than mass-produced carbon. Light cutting oil and slow rotation produce clean ribbons quickly.\u003c\/p\u003e\n\u003cp\u003eThe full thread-chasing-then-facing procedure is in the BB shell pillar; the Italian thread runs the same sequence with the spec swap: \u003ca href=\"\/blogs\/tech-tips\/frame-prep-threaded-bottom-bracket-shells\"\u003eFrame prep: threaded bottom bracket shells →\u003c\/a\u003e\u003c\/p\u003e","brand":"Unior","offers":[{"title":"Default Title","offer_id":44140828327980,"sku":"617590","price":222.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0012\/5786\/5260\/products\/1697.1.jpg?v=1648784296","url":"https:\/\/uniorusa.com\/products\/bottom-bracket-tap-cutters-ita","provider":"Unior USA","version":"1.0","type":"link"}
