HOLEMAKING
Customer demands have “necessitated us continuing to test new and improved tool designs, carbide grades and coatings,” Kueter said. Company research and development engineers “work with customers to fi nd the best drilling solu- tions for the most diffi cult applications.”
Longer Tool Life
“The use of more diffi cult-to-machine materials has caused the tooling manufacturers to look at the entire machining process,” said Walter USA’s Luke Pollock. “Coatings are becoming thinner, which helps retain sharp cutting edges.” “Walter has been focused on solid carbide deep-hole drill- ing for some time,” he said. “We currently offer solid carbide drills up to 50×D as a stock standard item and up to 70×D available on special order.” The company’s most recent production introduction is its DC170 drill. According to Walter, the DC170’s design results in increased cutting diameters and longer tool life. Walter

also has introduced its DB133 drill in 5 and 8×D lengths and diameters as small as 0.5 mm diam.
Sumitomo Electric Carbide Inc. (Mount Pleasant, IL) has come out with its line of MDW-GS drills the company said represents an improvement over its old MDS. MDS “works well in steels but had tough times in stainless with the standard edge prep as well as in exotic materials,” Rich Maton, engineering manager for Sumitomo, said in an e-mail.
“Customers are machining more and more superalloys. Tool life is generally very poor in these types of materials. Customers are asking for longer tool life.”
The new drill “lends itself well to steels, stainless steels and exotic materials,” he said. “The tool life is very good, even in deep-hole applications. Yes, customers are demanding deeper hole applications and harder materials to drill.” In terms of product cycle, he said, “On the drill line we typically keep them around for at least fi ve to seven years but continually revise if we fi nd a better coating or design change to help the customer out.”
Sumitomo also has a manufacturing plant in New Berlin,
WI, where customers can send drills back for regrinding and reconditioning, Maton said. “This ensures the customer can get consistent tool life time after time and have the exact same point and coating put on the used drills as their new drills.”
Talking to Customers Midwest Industrial Tool Grinding Inc. (MITGI; Hutchinson, MN) services customers in the medical device and aero- space industries. “We frequently have conversations with our customers about how we can solve problems they have in diffi cult-to- machine materials,” Eric Lipke, the company’s president, said in an e-mail. “Some of the most common issues our custom- ers face are related to the hard materials they are using. Often, we’ll need to look at a variety of tool features.” “We review each job to ensure that we can meet the com-

plex requirements of that specifi c situation,” he said. MITGI often produces customized tools. “For many customers, specials are the answer to complex manufacturing jobs,” said Jennie Nelson, the company’s
