Reduce scrap rate, eliminate breakage, reduce your cost per part.
Basic Carbide Corporation, Buena Vista, Pennsylvania found an additional benefit from using Precorps DiaEdge drills. Scrap rates were greatly reduced. Reducing cutting forces made it possible to drill a .061 in (1.55mm) blind hole over 4.6 in (116mm) deep in a relatively delicate green carbide preform. With carbide drills, it was not uncommon to break more than half of the preforms due to the rapid dulling of the drills cutting edges. DiaEdge twist drills eliminated preform breakage resulting in a substantially lower cost per part produced.
As a general rule, replacing tungsten carbide tooling with PCD in nonferrous applications yields an eight fold reduction in tool cost per piece produced.
As a general rule, replacing tungsten carbide tooling with PCD in nonferrous applications yields an eight fold reduction in tool cost per piece produced. However, the biggest gain comes from the decreased downtime associated with tool changes. One company found that a tool change was required after just four holes using conventional drills. Between each tool change the operator needed to resharpen the drill, and adjust his setup to account for the new drill length. Switching to DiaEdge twist drills allowed and entire lot of 100 parts to be finished with a single drill. This cut the time required to finish the job by more than half.
PCD twist drills provide producers of tungsten carbide die and wear parts with a new tool to tackle numerous shapes and forms. As a bonus, tool costs can be sharply reduced, along with significant gains in labor productivity.
