The synthetic diamond abrasive (SDC) ensures high controlled material removal capacity, profile stability, and maintenance of the cutting edge geometry even during intensive work cycles. Suitable for tool rooms and mechanical workshops specializing in tool maintenance, it allows for precise restoration of cutting angles, concentricity, and micro-geometry of the edge. Use with coolant improves heat dissipation and extends the operational life of the grinding wheel.\u003c\/p\u003e\n\u003chr\u003e\n\u003cp\u003e\u003c\/p\u003e\u003ch3\u003eMain specifications\u003c\/h3\u003e\n\u003cp\u003e• SDC synthetic diamond abrasive with extremely high hardness\u003cbr\u003e• Specific for carbide and tungsten carbide\u003cbr\u003e• High geometric profile stability\u003cbr\u003e• Precision grinding with controlled material removal\u003cbr\u003e• Excellent surface finish on sintered materials\u003cbr\u003e• Reduced wear and long operational life\u003cbr\u003e• Compatible with STG 42 sharpener\u003c\/p\u003e\n\u003chr\u003e\n\u003cp\u003e\u003cstrong\u003eTechnical table:\u003c\/strong\u003e\u003c\/p\u003e\n\n\n\u003ctable class=\"w-fit min-w-(--thread-content-width)\"\u003e\n\u003cthead\u003e\n\u003ctr\u003e\n\u003cth class=\"\"\u003eSpecification\u003c\/th\u003e\n\u003cth class=\"\"\u003eValue\u003c\/th\u003e\n\u003c\/tr\u003e\n\u003c\/thead\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003eType\u003c\/td\u003e\n\u003ctd\u003eSDC Diamond Grinding Wheel\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eMachine compatibility\u003c\/td\u003e\n\u003ctd\u003eSTG 42 Sharpener\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eAbrasive\u003c\/td\u003e\n\u003ctd\u003eSynthetic Diamond (SDC)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eApplication\u003c\/td\u003e\n\u003ctd\u003eGrinding and resharpening tools\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eWorkable materials\u003c\/td\u003e\n\u003ctd\u003eCarbide, tungsten carbide\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eUse\u003c\/td\u003e\n\u003ctd\u003eTool rooms and mechanical workshops\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\n\n\u003chr\u003e\n\u003cp\u003e\u003cstrong\u003ePackage contents:\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003e• SDC diamond grinding wheel for STG 42\u003cbr\u003e• Protective technical packaging\u003c\/p\u003e\n\n\u003ch3\u003eLogistics\u003c\/h3\u003e\n\u003cp\u003eBernardo shipping: 5–9 business days (7 days to the South).

SDC (diamond) grinding wheels are for tungsten carbide (HM\/TCT) tools — diamond abrasive is the only one that effectively works carbide without wearing out the grinding wheel. Using the wrong grinding wheel produces poor sharpening and premature wear of the grinding wheel itself.\u003c\/p\u003e\n\u003c\/details\u003e\n\u003cdetails\u003e\n\u003csummary\u003eIs this grinding wheel compatible with my Bernardo sharpener?\u003c\/summary\u003e\n\u003cp\u003eEvery Bernardo grinding wheel is specific to the model indicated in the title. Always check the sharpener model before purchasing — the outer diameter, thickness, and bore hole dimensions must match exactly. For compatibility confirmation, contact Krollit.

Replacement is necessary when the grinding wheel is worn down to its minimum diameter or when it produces irregular sharpening despite the correct procedure. There are no fixed intervals — it depends on the intensity of use.\u003c\/p\u003e\n\u003c\/details\u003e\n\u003cdetails\u003e\n\u003csummary\u003eDelivery times?\u003c\/summary\u003e\n\u003cp\u003eOriginal spare parts available with 3–5 business days shipping.
