Three Grades Well Suited for Deburring and Finishing Irregular Shaped Parts
Among the four Standard Abrasives™ Buff and Blend materials, HS material is the most stiff, durable and aggressive. Given its strength and durability, our Standard Abrasives™ Buff and Blend HS Disc is a good match for irregular shaped parts, such as pipe threads, the edges of molded glass containers, and non ferrous die cast molded parts. It removes small, stubborn burrs and cuts sharp to produce a consistent finish. Non woven construction makes the material responsive to contours and extrusions, so it is unlikely to gouge or mar the substrate while achieving an aggressive cut.

Aluminum oxide abrasive grain bonded to the nylon strands produces a uniform scratch pattern perfect for satin or grain finishing. Use a Standard Abrasives™ Buff and Blend HS Disc for final finishing on brass, steel, bronze, pewter, and stainless steel, as well as plated plastics. If desired, discs may be ganged on a shaft to form a wheel for off hand applications.

When a very fine high luster and decorative finish is desirable on pieces such as builders hardware, choose the HS Disc in MED or VFN grade. For applications that may require a faster cut or coarser finish, choose the CRS grade disc. The coarser scratch pattern of the CRS disc also makes it ideal for satin and grain finishing applications, as well as blending and cleaning surface imperfections.

• Satin and grain finishing of metal surfaces
• Blending and cleaning surface imperfections
• Blending out tool marks
• Markets include stainless steel fabricators, plumbing fixtures, metal fabricators, door hardware, food equipment Manufacturers, builder's hardware, aluminum extruded products, and aerospace
• Green

HS Medium Features and Applications

• Rigid, durable construction accomplishes edge breaking, deburring and finishing finish edges and welds
• Satin and grain finishing of metal surfaces
• Cleaning surface contamination
• Deburring and edge breaking
• Capable of withstanding high contact pressure without folding over when run as a plain disc
• Easily finishes contoured parts
• Produces a clean finish, without irregular scratches and “sparkles”
• Markets include stainless steel fabricators, plumbing fixtures, door hardware, food equipment manufacturers, aluminum extruded products, aircraft engine manufacturers, orthopedic implants
• Blue

HS Very Fine Features and Applications

• Excels at light deburring and final finishing of small, irregular shaped parts
• Light edge breaking on machined or stamped parts
• Edge radiusing
• Deburring threaded parts
• Pre finish of precious metals prior to polishing
• Markets include aerospace, aircraft equipment, foundries, machine builders, machine shops, and mold and die shops
• Maroon
• When your application calls for a lighter duty disc or if the final finish isn't as critical, we suggest our Standard Abrasives™ Buff and Blend GP or HP Disc. For off hand and automated finishing processes, we recommend the loftier Buf
