The K60 is suitable for sharpening HSS lathe tools, drills, chisels, and tools with moderately worn cutting edges. Do not use on tungsten carbide (HM) — corundum does not effectively work carbide and wears out quickly. For HM, use only SDC or CBN diamond grinding wheels.\u003c\/p\u003e\n\u003c\/details\u003e\n\u003cdetails\u003e\n\u003csummary\u003eIs this grinding wheel compatible with my bench grinder?\u003c\/summary\u003e\n\u003cp\u003eCheck the outer diameter (250 mm), thickness, and bore before purchasing — they must exactly match the machine's specifications. Also, check the maximum peripheral speed of the grinding wheel (indicated in m\/s) against the machine's spindle speed. Never mount a grinding wheel with a maximum speed lower than the machine's operating speed.
