Frequently Asked Questions
Q: What is the bore size of this ceramic abrasive grinding wheel?
A: The inner hole (bore) measures 20mm, making it compatible with most standard bench grinder and tool grinder spindles. Always verify your grinder's spindle diameter before mounting.
Q: Which abrasive type should I choose for sharpening high-speed steel drill bits?
A: The WA (White Fused Alumina) variant is specifically well-suited for high-speed steel, alloy steel, and high carbon steel. It offers very high hardness and sharpness for precise, efficient grinding of drill bits, blades, and gears.
Q: What grit size is best for finishing work versus rough grinding?
A: For aggressive stock removal and initial shaping, choose a coarser grit such as 46# or 60#. For precision finishing and fine sharpening, opt for 100# or 120#. The 80# grit is a great all-around middle-ground option.
Q: Is this grinding wheel suitable for grinding glass?
A: Yes. The GC (Green Silicon Carbide) type, known for its high hardness, is particularly effective on non-metal materials including glass, ceramics, and hard alloys.
