Where the 411T leaves a more rounded profile on prongs, the 411CT's sharply sloped concave cone geometry produces a more defined, crisply finished result. The \u003cstrong\u003etwincut (CT) blade geometry\u003c\/strong\u003e lets cut metal shavings clear freely from the bur, keeping the cutting action smooth and efficient on prong tips. The set is supplied in a plastic bur box with 48 holes for 3\/32 in shank burs.\u003c\/p\u003e\u003ch3\u003eFeatures\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eConcave cone shape for a sharply sloped, defined finish on prong tips\u003c\/li\u003e\n\u003cli\u003eTwincut (CT) blade geometry promotes efficient chip clearance during cutting\u003c\/li\u003e\n\u003cli\u003eCovers the complete Fig. 411CT size range, 0.80–2.30 mm\u003c\/li\u003e\n\u003cli\u003eSet of 16 burs, one in each size\u003c\/li\u003e\n\u003cli\u003eSupplied in a plastic bur box with 48 holes for 3\/32 in shank burs\u003c\/li\u003e\n\u003cli\u003eFor stone setting prong finishing and rounding work\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eNotes\u003c\/h3\u003e\u003cp\u003eThe \u003cem\u003eBusch Fig. 411T\u003c\/em\u003e, a cup bur with a traditional concave shape that leaves a softer, more rounded finish on prongs, is available separately.\u003c\/p\u003e","brand":"Busch Burs","offers":[{"title":"Default Title","offer_id":43582807834838,"sku":"B118.411000","price":65.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0609\/9832\/0342\/files\/busch-fig-411ct-twincut-concave-cone-cup-bur-kit-set-of-16-burs-0-80mm-2-30mm-otto-frei.jpg?v=1719956848","url":"https:\/\/www.ottofrei.com\/ja\/products\/busch-fig-411ct-twincut-concave-cone-cup-bur-kit-16-burs-0-80mm-2-30mm","provider":"Otto Frei","version":"1.0","type":"link"}
