Optional Tungsten Carbide Drill Considerations - Processing Cost Per Hole

Each hole machining productivity or cost is the most important factor in drilling of. In order to improve productivity, manufacturers are working on the drill bit can be integrated multiple step method for processing the operation, and to develop high feed, high speed processing of the drilling tool. The latest development of replaceable tungsten carbide drill crown having excellent machining economy. After the drill bit wear, users do not have to replace the entire drill body, you can simply replace carbide crown, which is equivalent to the purchase price of welded or solid carbide drill regrinding a fee. Carbide crown replacement is easy and highly reproducible precision machine shop drill body can be used with a plurality of teeth crowns, to the processing of different pore sizes of holes. This modular drilling system can reduce 12 ~ 20mm diameter drill cataloging costs, but can also save a backup tool costs when welding or solid carbide drills need to be reground.
