With the English taps and the facing cutter you bring the shell threads and faces back to the correct condition before installing the bottom bracket.\u003c\/p\u003e\n\u003cp\u003eThe heart of the system is the two-piece handle that passes through the bottom bracket shell: by connecting both sides, it keeps the right and left taps perfectly aligned with each other. The English taps check and restore thread alignment, and once threaded in they act as a guide for the cutter, so that the shell faces are machined square to the bottom bracket axis. Park Tool recommends using a cutting fluid, such as Park Tool CF-2, when machining.\u003c\/p\u003e\n\u003ch2\u003eHow the BTS-1 bottom bracket set works\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003eThe 692 left-hand tap works on the drive side of English-threaded shells, the 691 right-hand tap on the non-drive side.\u003c\/li\u003e\n\u003cli\u003eThe two-piece handle passes through the shell and keeps both taps on axis while threading.\u003c\/li\u003e\n\u003cli\u003eWith the taps in place, the 45 mm facing cutter (690) faces the shell using the taps themselves as a guide.\u003c\/li\u003e\n\u003cli\u003eThe result is a shell with aligned threads and parallel faces, ready for bottom bracket installation.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003eWhy choose Park Tool BTS-1\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003eTapping and facing in a single coordinated set.\u003c\/li\u003e\n\u003cli\u003eTwo-piece through-shell handle to keep both sides of the shell aligned.\u003c\/li\u003e\n\u003cli\u003eFaces machined square to the bottom bracket axis thanks to the tap guide.\u003c\/li\u003e\n\u003cli\u003eExpandable system: Park Tool offers as options the 693 Italian taps 36 mm x 24 TPI (two required), the 647R and 647L T47 taps (M47 x 1.0) and the 690-XL 57 mm oversized cutter.\u003c\/li\u003e\n\u003cli\u003eReplacement parts available for every component, from the 690, 690-XL and 690-XXL cutters to the 684S, 688 and 648R\/648L facing guides.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003eFor the workshop preparing new frames or rescuing bottom bracket shells with damaged threads, the \u003cstrong\u003ePark Tool BTS-1 tapping and facing set\u003c\/strong\u003e is the foundation for a precise, reliable bottom bracket installation.\u003c\/p\u003e\n\u003c\/section\u003e\n\u003ch3\u003eTECHNICAL SPECIFICATIONS\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\u003cdetails\u003e\u003csummary\u003e\u003cstrong\u003eGeneral\u003c\/strong\u003e\u003c\/summary\u003e\u003cul\u003e\n\u003cli\u003e\u003cstrong\u003eCode\u003c\/strong\u003e: BTS-1\u003c\/li\u003e\n\u003cli\u003e\u003cstrong\u003eType\u003c\/strong\u003e: tap and cutter set for threaded bottom bracket shells\u003c\/li\u003e\n\u003cli\u003e\u003cstrong\u003eHandle\u003c\/strong\u003e: two-piece, through-shell\u003c\/li\u003e\n\u003cli\u003e\u003cstrong\u003eRecommended cutting fluid\u003c\/strong\u003e: Park Tool CF-2 (not included)\u003c\/li\u003e\n\u003c\/ul\u003e\u003c\/details\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cdetails\u003e\u003csummary\u003e\u003cstrong\u003eCompatibility\u003c\/strong\u003e\u003c\/summary\u003e\u003cul\u003e\n\u003cli\u003e\u003cstrong\u003eThread\u003c\/strong\u003e: English 1.370\" x 24 TPI\u003c\/li\u003e\n\u003cli\u003e\u003cstrong\u003eOptions (not included)\u003c\/strong\u003e: 693 Italian taps 36 mm x 24 TPI; 647R\/647L T47 taps M47 x 1.0; 690-XL 57 mm cutter\u003c\/li\u003e\n\u003c\/ul\u003e\u003c\/details\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cdetails\u003e\u003csummary\u003e\u003cstrong\u003eContents\u003c\/strong\u003e\u003c\/summary\u003e\u003cul\u003e\n\u003cli\u003e\u003cstrong\u003e691\u003c\/strong\u003e: right-hand tap 1.370\" x 24 TPI (non-drive side, English thread)\u003c\/li\u003e\n\u003cli\u003e\u003cstrong\u003e692\u003c\/strong\u003e: left-hand tap 1.370\" x 24 TPI (drive side, English thread)\u003c\/li\u003e\n\u003cli\u003e\u003cstrong\u003e690\u003c\/strong\u003e: 45 mm facing cutter\u003c\/li\u003e\n\u003cli\u003e\u003cstrong\u003eHandle\u003c\/strong\u003e: two-piece\u003c\/li\u003e\n\u003c\/ul\u003e\u003c\/details\u003e\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"PARK TOOL","offers":[{"title":"Default Title","offer_id":58286939308372,"sku":"PKBTS1","price":908.9,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0954\/5223\/4068\/files\/671e757c4e2478e62ec4c4150fa64340fcb749cacd1420f0471cee43c031a94f.png?v=1794417543","url":"https:\/\/www.pro-mstore.com\/en\/products\/bottom-bracket-tapping-and-facing-set-park-tool-bts-1","provider":"Pro-M SRL","version":"1.0","type":"link"}
