Product Description

The preparation method of conventional PCD drill bits is usually to process a groove at the drill tip, use wire cutting to cut the PCD film deposited on the cemented carbide substrate to shape, and then weld it in the drill bit’s tip groove. In the early 1990s, welded PCD drill bits were used to drill the positioner holes on automobile engine pistons. The pistons are hypereutectic aluminum alloy castings (silicon content above 12%), and PCD drill bits must be used to process the required tools. Life, a drill can usually process 3,500 pairs of holes once sharpened (in fact, it may process 10,000 pairs of holes). However, the processing time of welded PCD drill bit is longer, and the processing cost per piece is higher. In addition, the cutting edge of the drill often suffers from welding failure under the action of high temperature, which leads to the damage of the entire drill. The use of integrally sintered PCD drill bits can better solve the above problems.
