The diamond coating provides the hardness to penetrate brittle materials cleanly – where standard HSS or carbide bits would chip or crack the workpiece. At 1.5mm, this bit bridges the gap between the ultra-fine 1.0mm and the larger 3.2mm ball bit, making it ideal for slightly larger precision holes in tile, glass, and stone.\u003c\/p\u003e\n\u003ch3\u003eKey Features\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDiamond-coated tip\u003c\/strong\u003e – Penetrates glass, ceramics, porcelain, and hard stone\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e1.5mm diameter\u003c\/strong\u003e – Precision drilling for detail work in hard brittle materials\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e2.35mm shank\u003c\/strong\u003e – Fits all Proxxon MICROMOT collet tools\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoolant required\u003c\/strong\u003e – Use with water or cutting fluid to prevent overheating\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBest at 2,000 RPM\u003c\/strong\u003e – Use on a drill press for controlled, consistent results\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eSpecifications\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDiameter:\u003c\/strong\u003e 1.5mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank:\u003c\/strong\u003e 2.35mm (3\/32\")\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating:\u003c\/strong\u003e Diamond\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRecommended speed:\u003c\/strong\u003e 2,000 RPM\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoolant:\u003c\/strong\u003e Required\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eBest Suited For\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eGlass drilling and engraving\u003c\/li\u003e\n\u003cli\u003eCeramic and porcelain tile detail work\u003c\/li\u003e\n\u003cli\u003eHard stone and semi-precious stone\u003c\/li\u003e\n\u003cli\u003eMosaic and lapidary applications\u003c\/li\u003e\n\u003cli\u003eJewelry and craft precision drilling\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eWorks Well With\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eProxxon IBS\/A Cordless Drill\/Grinder – Cordless MICROMOT rotary tool for flexible use\u003c\/li\u003e\n\u003cli\u003eProxxon Diamond Drilling \u0026amp; Grinding Bit 1.0mm – Finer bit for smaller holes in the same materials\u003c\/li\u003e\n\u003cli\u003eProxxon Diamond Drilling \u0026amp; Grinding Bit 3.2mm Ball – Ball-shaped bit for concave grinding and milling\u003c\/li\u003e\n\u003cli\u003eProxxon Diamond Twist Drills 0.8mm + 1.2mm – Twist drill format for cleaner entry holes\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Proxxon","offers":[{"title":"Default Title","offer_id":69023463866562,"sku":"28232","price":8.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0705\/0048\/3266\/files\/28232.jpg?v=1794556009","url":"https:\/\/skylinestoneproducts.com\/products\/proxxon-diamond-drilling-grinding-bit-1-5mm","provider":"Skyline Stone Products","version":"1.0","type":"link"}
