Standard Abrasives™ Buff and Blend Cross Buff HP has great versatility and may be used for a variety of applications, including cleaning, removing surface oxidation, rust and surface coatings for part inspection, surface preparation prior to coating, removing corrosion on steel rule and kirksite dies. Standard Abrasives™ Buff and Blend Cross Buff HP polishes round and square tubing, valve spools, molds, dies and inside diameters of lifter bore, valve bodies and brake cylinders. Standard Abrasives™ Buff & Blend Products are made from tough, resin-reinforced nylon fiber with aluminum oxide abrasive grain. Each of the Standard Abrasives Buff & Blend materials offers unique benefits. HP is a stiff material that produces an aggressive cut rate, designed for applications where metal removal is required. We used aluminum oxide mineral, which is a popular choice among industrial professionals because of its fast cut-rate and long life. This mineral makes for a tough, durable abrasive that self-fractures to expose fresh cutting edges, whereas traditional natural abrasives dull more quickly. Due to its fast cut-rate, hardness, and strength, it is widely used in grinding applications in addition to sanding and finishing applications. Aluminum oxide is suitable for a wide variety of materials in both woodworking and metalworking, including ferrous alloys.
