Specification Brand : Auniwaig BulletPoint : Norton 7" Diameter 1/4" Thick 1-1/4" Hole Size 100 Grit 38A Aluminum BulletPoint1 : 【High Quality】- Diamond abrasives have the characteristics of high hardness, high compressive strength and good wear resistance, so the diamond grinding wheel is an ideal tool for grinding. BulletPoint2 : 【Multifunction】- Resin bond synthetic diamond cup grinding wheel is mainly used for surface grinding and external grinding BulletPoint3 : 【Design】- Diamond grinding wheel is made of three parts, abrasive grain is uniform, so it has high grinding precision;Good roughness, less abrasive consumption and durable for use BulletPoint4 : 【Wide Application】- Widely used in cemented carbide, tungsten steel, high speed steel, alloy steel, glass, ceramics, etc. BulletPoint5 : 【Dimension】- Abrasive Material: Diamond,Resin; Inner diameter:20mm / 0.79-inch; Outer diameter: 100mm / 3.94-inch;Height: 8mm / 0.31-inch; Granularity / mesh: 150 Grits Color : 5 Inch CompatibleDevices : Angle Grinder ConstructionType : bonded,grinding CustomerPackageType : Standard Packaging ExternallyAssignedProductIdentifier : 30638060064604 ExternallyAssignedProductIdentifier1 : 841674116167 ExternallyAssignedProductIdentifier2 : 0841674116167 ExternallyAssignedProductIdentifier3 : 00097758611138 IncludedComponents : Cut & Grind Wheel IndustryStandardIdentifier : Type 27 ItemName : Auniwaig 3.94-Inch 150 Grits Diamond Grinding Wheels 100mm,Aluminum,Resin Bonded Abrasive Wheel for Cemented Carbide, Tungsten Steel, High Speed steel, Alloy Steel, Glass, Ceramics ItemPackageDimensions_Height : 13.3 centimeters ItemPackageDimensions_Length : 1.1 centimeters ItemPackageDimensions_Width : 9.8 centimeters ItemPackageQuantity : 1 ItemShape : Round ItemTypeKeyword : surface-grinding-wheels Manufacturer : Auniwaig Material : Ceramic MaximumRotationalSpeed : 13300 rpm ModelName : 3M Cut & Grind Wheel, 06460, Type 27, 4 in x 1/8 in x 3/8 in, 10 per inner ModelNumber : CU2100S0702HF-FBA NumberOfItems : 10 PartNumber : CU2100S0702HF-FBA ProductDescription : Auniwaig Carbide Diamond Grinding Wheels Package Content: 1pcs x Diamond Grinding Wheels Specification: Abrasive material: Diamond,Resin Inner diameter:20mm / 0.79-inch Outer diameter: 100mm / 3.94-inch Height: 8mm / 0.31-inch Color:Random Color Sand thickness:4mm/0.16inch Granularity / mesh: 150 Grits Description: 1.Resin bond synthetic diamond cup grinding wheel is mainly used for surface grinding and external grinding. 2.Diamond abrasives have the characteristics of high hardness, high compressive strength and good wear resistance, so the diamond grinding wheel is an ideal tool for grinding. 3.Not only high efficiency, high precision, but also good roughness, less abrasive consumption and long service life. 4.The diamond grinding wheel is generally composed of a working layer, a base body and a transition layer. The work is meticulous and the grinding precision is high. 5.It is widely used in low-iron content metal and non-metal hard and brittle materials, such as hard alloy, high-aluminum porcelain, optical glass, agate gemstone, semiconductor material, stone, etc., which are difficult to process with ordinary abrasive tools. Note: Due to different purchase batches, the colors will be shipped randomly.
