Surface Prep Buff and Blend Discs (1 and 2-Ply) How are Surface Prep Buff and Blend Discs constructed? The discs are 1 and 2-ply to help reduce lines while preparing metal.

MAKITA 9237C- The best 3,500 RPM polishing machine (PROS & BEGINNERS) This machine is variable speed so you can use these wheels at a lower RPM such as 1,000 - 1,200. What are the safety requirements for buffing wheels & metal polishing? We HIGHLY recommend that you use a full face respirator mask! This FULL FACE RESPIRATOR MASK is highly recommended and great quality. When do I use Surface Prep Buff and Blend Discs? Surface Prep Buff and Blend Discs should be used for moderate surface cleaning and deburring (smoothing) before polishing. After surface preparation, one may choose to follow up with sanding at 320 Grit to remove any remnants left behind by the disc. For a final polish, follow up with fine-grit Sanding Disc, then use the Tripoli compound and an Airway Buffing Wheel. The Very Fine/Maroon disc and the Coarse/Green Buff and Blend Disc should be run at about 1,800 RPM, while the Medium/Blue Disc can be run at approximately 2,500 RPM. 6", 8", 9", and 10" diameter wheels have a 1/2" arbor hole. 14" wheels have a 1-1/4" arbor hole.
