Grinding of deposited materials is one of the methods of processing machine parts that require repair after heavy use. The question of increasing the efficiency of grinding of deposited materials with a diamond-abrasive tool is considered. Problems in the processing of deposited materials and ensuring the quality and physical and mechanical condition of the processed surface are studied. Testing of grinding of deposited materials from a special duplex alloy with various abrasive tools was carried out, and the efficiency of removing the treated material and the wear of the abrasive tool were evaluated.                     The purpose of the work is to test various diamond-abrasive tools for manual grinding of deposited materials from special alloys.                      Diamond abrasive heads with a diameter of 10 mm made of white and chromium electrocorundum, silicon carbide, and synthetic diamond were used for processing the welded materials when grinding with a professional-grade manual power tool.                     The results of comparative tests of different abrasive heads for grinding of welded materials showed a high efficiency of processing with abrasive heads made of chromium corundum and diamond, and the wear of the heads was minimal.                     The results of the test of diamond-abrasive heads allow us to evaluate the effectiveness of the use of various tools when grinding deposited materials and give recommendations for industry.
