FUJI KOSOKU Cement Bonded Wheel — バインといし
The FUJI KOSOKU Cement Bonded Wheel, named バインといし in the Japanese catalog, is a specialist wheel for water-cooled blade sharpening on compatible knife grinders. Its catalog dimensions are 70 × 4 × 10 mm (outside diameter × thickness × bore), with a one-side taper profile.
The catalog specifies use with バイングラインダ and describes a light grinding touch. Water cooling and controlled contact help limit heat at the blade edge during sharpening. Results depend on the approved machine, cooling and operating conditions; this is not an unconditional guarantee against overheating or loss of hardness.

These are the catalog specifications for this wheel, not a recommendation to operate every sharpening machine at the maximum speed. Follow the wheel marking and the approved machine instructions, including any lower operating limit.
The 10 mm bore alone does not establish compatibility. Before ordering, confirm the machine model, approved wheel dimensions and profile, mounting components, guard, operating speed and water-cooling arrangement. Use the wheel only on equipment approved for this type of wet sharpening.
This product should not be selected as a general-purpose 3-inch angle-grinder disc, an air cut-off wheel or a dry-grinding accessory. It is intended for sharpening blade edges, rather than weld removal, steel cutting or general rust removal. Do not use an adapter as a substitute for manufacturer-confirmed compatibility.
Use water cooling as specified by the compatible sharpening machine. Inspect the wheel and mounting before use, and follow the equipment instructions for guarding, contact pressure and shutdown. Stop and investigate abnormal vibration, wheel damage, interrupted cooling or unacceptable heat at the edge.
Do not leave the wheel immersed in a water tank for prolonged periods unless the manufacturer expressly permits it. Follow the machine and wheel instructions for draining, drying and storage after use. Do not adopt a fixed one- or two-minute spin-drying procedure without confirmation for the particular equipment. Keep stored wheels protected from damage and unsuitable moisture conditions according to the manufacturer's instructions.
The catalog name identifies the product as a Cement Bonded Wheel; it does not specify the complete binder formulation, grit or abrasive composition. Ask FUJI for any additional technical information required by your process rather than assuming these properties from the name.
The catalog specifies a 70 mm outside diameter, 4 mm thickness and 10 mm bore. Order by these dimensions and the product name rather than an approximate inch size.
The catalog identifies it as exclusively for water-cooled sharpening. Do not substitute dry operation for the specified wet process.
No. Metres per second describe speed at the wheel's circumference; rpm describes rotations per minute. The catalog lists 41 m/s and 11,100 rpm as maximum values. Respect the marked limits and the compatible machine's instructions.
No. Matching the bore is only one requirement. Confirm the specific knife grinder, mounting system, wheel profile, guard and cooling arrangement with FUJI.
