When that surface layer wears away, the bit stops working effectively. A sintered diamond grinding head, like this one, has diamond particles distributed throughout the entire body of the bit. As the outer layer wears, new diamond abrasive is continuously exposed, giving it a service life more than 10 times longer than electroplated alternatives.\u003c\/p\u003e\n\u003ch4\u003eQ: What tools is this sintered diamond grinding head compatible with?\u003c\/h4\u003e\n\u003cp\u003eA: This grinding point features a 2.35mm shank, making it compatible with most standard Dremel rotary tools and air grinders that accept a 2.35mm (3\/32\") collet or chuck. Always verify your tool's collet size before use.\u003c\/p\u003e\n\u003ch4\u003eQ: What materials can this P70 grit grinding head be used on?\u003c\/h4\u003e\n\u003cp\u003eA: This P70 (coarse grit) sintered diamond grinding point is suitable for grinding and shaping jade, ceramic, alloy, and similar hard materials. The coarse grit makes it ideal for aggressive material removal and rough shaping tasks.\u003c\/p\u003e\n\u003ch4\u003eQ: Will the grinding head fit a standard Dremel tool?\u003c\/h4\u003e\n\u003cp\u003eA: Yes. The 2.35mm shank is the standard size used by most Dremel rotary tools. It is recommended to check that your specific Dremel model accepts a 2.35mm collet for a secure fit.\u003c\/p\u003e\n\u003c!-- production-packaging-notice --\u003e\n\u003ch3\u003eProduction \u0026amp; Packaging Notice\u003c\/h3\u003e\n\u003cp\u003eTo maintain high stock availability and fast shipping times, our items are sourced from multiple verified manufacturing facilities.
