Surface Conditioning Quick Change Sanding Discs
Premium: PREMIUM Surface Conditioning Discs are made from stiff scrim backed material designed exclusively for disc use, and have excellent grain retention and are smear resistant. They are great for deburring, blending machine tool marks, general surface cleaning, gasket removal and heavy rust and oxidation removal. GP: GENERAL PURPOSE Surface Conditioning Discs are made from stiff scrim backed material designed exclusively for disc use. Best choice for economical deburring. They are great for deburring, blending machine tool marks, general surface cleaning, gasket removal and heavy rust and oxidation removal. Max-Finish: MAX-FINISH Surface Conditioning Discs feature a softer scrim backing and will leave a smooth finish without leaving any "stray" scratches. They are less aggressive than our Premium discs, great when surface finish is the primary concern. HD: HEAVY DUTY Surface Conditioning Discs are a combination of AO and Ceramic grains, with additional resin for added strength and durability. These discs are very stiff and aggressive, which make them the best choice for heavy deburring, weld grinding, and splatter removal. -
Hi-Strength Quick Change Sanding Discs
High-Strength fibers combined with high grain content make these durable discs ideal for light deburring or final finishing work. Strong fibers resist snagging or tearing. Great for final finish on aerospace parts or edge deburring on extrusions. Easily conforms to irregular surfaces. -
Finishing Quick Change Sanding Discs
Finishing discs are made of soft “hand pad” type material. They can remove slight imperfections, light oxidation, and other minor defects. NOT intended for deburring. Designed for light removal of coatings, oxidation, or rust without affecting the base product. The aluminum oxide grain and resin bond combination produce a smooth cut rate and smear-free uniform finish. -
Unitized Quick Change Sanding Discs
XL Unitized Discs are a great choice for light deburring, and blending, as they provide a consistent, uniform finish. These discs are smear resistant and have a long life. 6AM - Capable of heavier deburring and surface finishing. 2SF & 2AM - light deburring and removal of imperfections without altering base material. GFP - Green Final Polish wheels will leave a bright "mirror like" final finish on a variety of metals. They will not alter part geometry and do not require compound! CP Unitized Discs – Better choice for light weld bead and weld splatter removal and heavy deburring and finishing applications. 3AM, 5AM, 7AM – High performance engineered grain. Harder and more durable than XL wheels. Aggressive fast stock removal with nice finish.
How to Create #4 Stainless Steel Finish
No. 4 finish is a popular polishing choice for several industries and products. It is characterized by short, parallel polishing lines and is the easiest of the stainless finishes to maintain. The final finish will depend on the material’s application and can range between 120 – 320 grit.
There are 4 basic steps for creating or blending a #4 stainless steel finish:
- Leveling the Weld – we suggest using either a Resin Fiber Sanding Disc or a Flap Disc
- Setting the Grain – we suggest using either a Belt or a Flap Wheel
- Final Finishing – we suggest using a Surface Condition Belt
- Final Blending/ Touch Up – we suggest using a Hand Pad
