> 24 hourI wanted to replace one of the gray wheels on my grinder with a finer grit for finish grinding of my more expensive tools and knives. This stone is perfect for the job. The price was good as well. I am satisfied with the purchase.

> 24 hourAfter 15 minutes of use on mild steel this wheel lost a full 1/4” of diameter and developed a center groove. It is also nearly 1mm out of round, making for terrible vibration of my grinder. I would not recommend this product. Cheap price, but you get what you pay for. Crap, basically I give them points for good packaging, but that’s about all.

> 24 hourBalanced friable stone, good for grinding high speed steel without burning or bluing. Perhaps a bit course than 80 grit as described.

> 24 hourAbsolutely beyond being saved by dressing either with a dressing stick or Diamond dresser. It has been returned today for a refund. Note this fault is not uncommon with cheap grinding wheels? They are produced in large quantities without high levels of quality control? I bought a green silicone carbide wheel from same manufacturer/supplier that’s absolutely fine just required a light dressing. If you read other reviews you will see customers have same issues!

> 24 hourWas a little difficult to center accurately, but much better than the Norton wheel that I bought at the same time.

> 24 hourThe central arbor hole is not parallel to the sides of the stone. It shakes side to side in a big way. It cuts HSS tools OK, but is scary to use due to improperly bored hole.

> 24 hourI use this for sharpening metal-cutting, twist bits. These sharpen at a medium rate, not too fast/slow, providing a clean, fine finish. I will this one again.

Grinding wheel parameter meaning
The main parameters of grinding wheel are abrasive, hardness, particle size, binder, etc.
Grinding wheel is mainly composed of abrasive, adhesive and pore.
1, Abrasives: ordinary abrasives (generally artificial abrasives) and super hard abrasives (generally natural abrasives).
Common abrasives are silicon carbide and aluminum oxide (corundum). Super hard abrasives include diamond and cubic boron nitride.
2, Adhesive: ceramic, resin, rubber, metal and so on. Ceramic binders are the most commonly used.
3, Pores: reduce the binding strength of the adhesive, storage grinding down abrasive.
The grinding wheel with ceramic bond is the most widely used and most commonly used grinding wheels for grinding tools
The hardness of the grinding wheel is divided into 14 grades: A-F is super soft, L is medium soft, and Y is super hard.
The hardness of the grinding wheel is inversely proportional to the hardness of the tool. For processing soft metals, choose hard grinding wheels. For hard metals, choose softer wheels
For the grinding of ordinary cemented carbide tools, softer green silicon carbide grinding wheels are selected, which has low cost and high efficiency
For the grinding of super hard tools, natural diamond and cubic boron nitride grinding wheels (CBN) are recommended, which are costly and slow to consume
The grinding wheel has low hardness and is suitable for grinding tools with high hardness. Abrasive grains fall off easily. Grinding tools are fast and efficient, Such as our L grade green silicon carbide grinding wheel, But the wear of the grinding wheel is slightly larger
The grinding wheel has high hardness, which is suitable for grinding tools with low hardness. The abrasive grains are not easy to fall off, and it is easy to generate a lot of heat, causing burns to the workpiece. Grinding tools is slow and inefficient. The wear of the grinding wheel is small
The particle size of the grinding wheel is mainly the size of the abrasive particles. The smaller the number, the larger the particles, the rougher the grinding tool and the higher the efficiency. The particles are small, the grinding tools are fine, and the efficiency is low. Granularity number: 16-240. No. 16-54 belongs to coarse grinding, No. 60-100 belongs to general fine grinding, and above 120 belongs to fine grinding.
