Its straight cylindrical profile with a flat end is particularly useful for working on flat surfaces, straight walls, recesses, edges, and other areas where controlled abrasive removal is required.\u003c\/p\u003e\n\n\u003cp\u003eCoated with medium-grit diamond abrasive, the #842 provides an excellent balance between efficient material removal and surface control. Unlike conventional toothed burs, the diamond-coated surface removes material through abrasion, making it particularly useful for gemstones, glass, ceramics, and other hard or brittle materials. The standard Ø2.35 mm shaft fits common jewellery flex shaft and micromotor handpieces.\u003c\/p\u003e\n\n\u003ch2\u003eKey Features\u003c\/h2\u003e\n\u003cul\u003e\n    \u003cli\u003e\n\u003cstrong\u003eDiamond Coated:\u003c\/strong\u003e Abrasive diamond surface for grinding, shaping, and refining hard materials\u003c\/li\u003e\n    \u003cli\u003e\n\u003cstrong\u003eFlat Cylinder Profile:\u003c\/strong\u003e Ideal for working on flat surfaces, straight edges, walls, and recesses\u003c\/li\u003e\n    \u003cli\u003e\n\u003cstrong\u003eFlat Cutting End:\u003c\/strong\u003e Useful for controlled abrasive work on flat-bottomed areas\u003c\/li\u003e\n    \u003cli\u003e\n\u003cstrong\u003eMedium Grit:\u003c\/strong\u003e Good balance between efficient material removal and controlled surface refinement\u003c\/li\u003e\n    \u003cli\u003e\n\u003cstrong\u003ePrecision Control:\u003c\/strong\u003e Suitable for detailed jewellery, gemstone, and stone setting work\u003c\/li\u003e\n    \u003cli\u003e\n\u003cstrong\u003eShaft Diameter:\u003c\/strong\u003e Ø2.35 mm\u003c\/li\u003e\n    \u003cli\u003e\n\u003cstrong\u003eBusch Quality:\u003c\/strong\u003e Precision-made rotary tool for professional jewellery and workshop applications\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch2\u003eApplications\u003c\/h2\u003e\n\u003cul\u003e\n    \u003cli\u003eGrinding and shaping gemstones\u003c\/li\u003e\n    \u003cli\u003eLevelling and refining flat surfaces\u003c\/li\u003e\n    \u003cli\u003eWorking with glass and ceramic materials\u003c\/li\u003e\n    \u003cli\u003eRefining recesses, edges, and straight walls\u003c\/li\u003e\n    \u003cli\u003eStone setting and jewellery fabrication\u003c\/li\u003e\n    \u003cli\u003eLapidary, jewellery repair, and precision workshop work\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003cp\u003eA versatile medium-grit diamond cylinder bur for jewellers, stone setters, and lapidary workers who require precise abrasive shaping and controlled material removal on hard materials.\u003c\/p\u003e","brand":"Busch","offers":[{"title":"842 021 - 2.1mm x 12mm","offer_id":67590511263838,"sku":null,"price":13.99,"currency_code":"AUD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1441\/9078\/files\/Busch_842.png?v=1790754102","url":"https:\/\/koodak.com.au\/products\/busch-842-diamond-coated-cylinder-flat-bur-medium-grit-2-35mm-shaft-eol","provider":"Koodak Jeweller's Supplies","version":"1.0","type":"link"}
