The use of synthetic diamond (SDC) allows for a high controlled removal capacity, maintaining profile stability and dimensional precision even on complex geometries. Suitable for tool rooms and specialized mechanical workshops for tool maintenance, it ensures uniform surface finishes, reduced wear, and a long operational life. Use with coolant further improves heat dissipation and preserves the abrasive's characteristics over time.\u003c\/p\u003e\n\u003chr\u003e\n\u003cp\u003e\u003c\/p\u003e\u003ch3\u003eKey Specifications\u003c\/h3\u003e\n\u003cp\u003e• SDC synthetic diamond abrasive with very high hardness\u003cbr\u003e• Specifically for carbide and tungsten carbide\u003cbr\u003e• High geometric profile stability\u003cbr\u003e• Precision grinding with uniform surface finish\u003cbr\u003e• Reduced wear and long service life\u003cbr\u003e• Controlled material removal with low heat generation\u003cbr\u003e• Compatible with DG 13 M sharpening machine\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\u003eDG 13 M sharpening machine\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\u003eTool grinding and re-sharpening\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\u003eMechanical workshops and tool rooms\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 DG 13 M\u003cbr\u003e• Protective technical packaging\u003c\/p\u003e\n\n\u003ch3\u003eLogistics\u003c\/h3\u003e\n\u003cp\u003eBernardo shipping: 5–9 working days (7 days to the South).

SDC (diamond) wheels are for tungsten carbide (HM\/TCT) tools — diamond abrasive is the only one that effectively works carbide without wearing down the wheel. Using the wrong wheel results in poor sharpening and premature wear of the wheel itself.\u003c\/p\u003e\n\u003c\/details\u003e\n\u003cdetails\u003e\n\u003csummary\u003eIs this wheel compatible with my Bernardo sharpener?\u003c\/summary\u003e\n\u003cp\u003eEach Bernardo 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 wheel is worn to its minimum diameter or when it produces uneven sharpening despite 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 working day shipping.
