Speed up delivery with the EdgeX4
This solid-PCD cross-center-tipped drill meets production goals while reducing cost per hole.
Speed, strength, longevity and efficiency reportedly enable the EdgeX4 solid-PCD cross-center-tipped drill to meet production goals and reduce the cost per hole. Developed by West Ohio Tool Co., Russells Point, Ohio, the tool is applicable to any industry that drills composites, plastics, aluminum and other nonferrous metals.
“One of the ways that it’s faster is its four- to six-week delivery time,” said CFO Kaci King.
She said that is 75% faster than the standard lead time for PCD specials. In addition, the tool reduces cycle times.
“It runs at faster speeds because we use the strongest PCD material available,” King said.
She said the material improves wear resistance compared with a standard PCD grade.
PCD is measured by grain sizes that range from nanometers to hundreds of micrometers, usually referred to as nanocrystalline and microcrystalline, said Kerry Buchenroth, founder of West Ohio Tool. Smaller particles in higher quantities provide a higher-grade tool. The concentration of higher-quantity grain improves tool performance.

King said the EdgeX4 offers a cutting speed that is up to three times faster than a solid-carbide drill. The drill’s cross-center tip eliminates all carbide cutting edges.

By having a drill with PCD across its entire center, one customer extended tool life from 350,000 holes with an outboard-tipped PCD drill to 1 million holes with the EdgeX4, she said. The concentrated PCD provides an attractive material for machining carbon fiber-reinforced polymer composites in terms of long tool life, high cutting speeds, fine surface quality, short cycle times and enhanced cost efficiency.
Depending on the application, 800,000 to 1 million holes can be drilled with the EdgeX4 without regrinding or re-tipping, King said. Also, premature breakdowns of drill points are reduced. In comparison, solid-carbide drills achieve approximately 25,000 holes and can be reground a maximum of 10 times after producing 20,000 holes for each regrind. PCD outboard-tipped drills achieve 350,000 holes without a regrind or re-tip when drilling die-cast aluminum.
“Anytime you go from 250,000 to 800,000, cost per hole is so cheap,” Buchenroth said.
Benefits include needing fewer tools in inventory, having fewer breakdowns and reducing machine downtime.
“Many people that manufacture diamond drills are doing outboard tipping,” Buchenroth said. “The carbide center at the chisel is what takes all the beating in a carbide or outboard-tipped drill.”
The EdgeX4 has been tested in the laboratory and by manufacturing partners of West Ohio Tool across the U.S., he said.
