Long-life abrasive pad assembly

Abstract

An abrasive pad assembly, comprising having an abrasive layer having first and second surfaces with the first surface being coated with material particles having predetermined hardness characteristics, a substrate having first and second surfaces with the first surface attached to the second surface of the abrasive layer, the substrate being composed of a material having stiff and resilient characteristics, and a fastening layer having first and second surfaces with the first surface being attached to the second surface of the substrate and the first surface having fastening material disposed thereon.

What is claimed is: 
     
         1 . An abrasive pad assembly, comprising:
 a. An abrasive layer having first and second surfaces with the first surface being coated with material particles having predetermined hardness characteristics;   b. A substrate having first and second surfaces with the first surface attached to the second surface of the abrasive layer, the substrate being composed of a material having stiff and resilient characteristics; and   c. A fastening layer having first and second surfaces with the first surface being attached to the second surface of the substrate and the first surface having fastening material disposed thereon.   
     
     
         2 . The abrasive pad assembly according to  claim 1 , wherein the fastening material comprises loop fabric. 
     
     
         3 . The abrasive pad assembly according to  claim 1 , wherein the material articles are composed of at least one of diamond, cubic boron nitride, aluminum oxide, silicon carbide, and garnet. 
     
     
         4 . The abrasive pad assembly according to  claim 1 , wherein the substrate is composed of any of steel, brass, and aluminum. 
     
     
         5 . A handheld tool assembly, comprising:
 a. a motor   b. a fastening surface operably connected to the motor; and   c. an abrasive pad assembly, comprising:
 i. an abrasive layer having first and second surfaces with the first surface being coated with material particles having predetermined hardness characteristics; 
 ii. a substrate having first and second surfaces with the first surface attached to the second surface of the abrasive layer, the substrate being composed of a material having stiff and resilient characteristics; and 
 iii. a fastening layer having first and second surfaces with the first surface being attached to the second surface of the substrate and the first surface having fastening material disposed thereon; 
   d. wherein the fastening layer is removably connected to the fastening surface.   
     
     
         6 . The handheld tool assembly according to  claim 5 , wherein the fastening surface comprises one of hook and loop material, and the fastening layer comprising the other of hook and loop material. 
     
     
         7 . The handheld tool assembly according to  claim 5 , wherein the fastening material comprises loop fabric. 
     
     
         8 . The handheld tool assembly according to  claim 5 , wherein the material articles are composed of at least one of diamond, cubic boron nitride, aluminum oxide, silicon carbide, and garnet. 
     
     
         9 . The handheld tool assembly according to  claim 5 , wherein the substrate is composed of any of steel, brass, and aluminum.
