T-segment core bit for drilling through-holes in slab, on a 5\/8 in.-11 thread, supplied with brazed diamond side protection inside and outside the barrel. Ocean Diamond specifies wet use only on engineered stone and quartz, and dry or wet use on other materials; the 2-1\/4 in. size is rated to a 4,000 RPM maximum, lower than the 6,500 RPM of the 2 in. and smaller bits. It is a heat-resistant metal-bond bit whose T-shaped segments are designed to stop segments coming off under dry use.\u003c\/p\u003e\n    \u003cp\u003eEngineered stone and quartz are wet-only on this bit whatever the line name says — the dry-or-wet instruction applies to granite and quartzite. Side protection is not universal across the family: the 2-1\/4 in. bit has it, while the neighbouring 2-3\/8 in. and 2-1\/2 in. bits do not. For ultra-compact and Dekton, use the APEXX Green Thin-Wall Core Bit – 2-1\/4 in., 5\/8 in.-11, for Porcelain \u0026amp; Ultra-Compact; for marble and porcelain, the APEXX Vacuum Brazed Marble \u0026amp; Porcelain Core Bit.\u003c\/p\u003e\n  \u003c\/div\u003e\n  \u003cdiv class=\"key-features\"\u003e\n    \u003ch3\u003eKey Features\u003c\/h3\u003e\n    \u003cul\u003e\n      \u003cli\u003e2-1\/4 in. diameter\u003c\/li\u003e\n      \u003cli\u003e5\/8 in.-11 thread\u003c\/li\u003e\n      \u003cli\u003eT-segment, heat-resistant metal bond\u003c\/li\u003e\n      \u003cli\u003eBrazed diamond side protection inside and outside the barrel\u003c\/li\u003e\n      \u003cli\u003e4,000 RPM maximum\u003c\/li\u003e\n      \u003cli\u003eWet use ONLY on engineered stone and quartz; dry or wet on other materials\u003c\/li\u003e\n      \u003cli\u003eOcean Diamond materials: engineered stone, granite, natural quartzite\u003c\/li\u003e\n    \u003c\/ul\u003e\n  \u003c\/div\u003e\n  \u003cdiv class=\"ideal-for\"\u003e\n    \u003ch3\u003eWho Is This For?\u003c\/h3\u003e\n    \u003cp\u003eFabricators and installers drilling large fixture, drain and post holes in engineered stone, granite and quartzite on a hand-held grinder or drill motor.\u003c\/p\u003e\n  \u003c\/div\u003e\n  \u003cdiv class=\"faq\"\u003e\n    \u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\n    \u003cdiv class=\"faq-item\"\u003e\n      \u003ch4\u003eWhat diameter is it?\u003c\/h4\u003e\n      \u003cp\u003eThe core bit is 2-1\/4 in. in diameter, on a 5\/8 in.-11 thread.\u003c\/p\u003e\n    \u003c\/div\u003e\n    \u003cdiv class=\"faq-item\"\u003e\n      \u003ch4\u003eCan it be used dry on quartz?\u003c\/h4\u003e\n      \u003cp\u003eNo. Ocean Diamond specifies wet use only on engineered stone and quartz.
