Holemaking cy, adds Chet Parzick, Kennametal product manager, inorder to avoid damaging the part when drilling work-pieces that can cost between $35,000$200,000. ֓In this industry, youre talking about jet engines spinning at high speed, and itҒs been pretty well accepted that componentfailure starts at a hole, notes Parzick. ԓA hole is consid-ered abusive machining in this industry, so the drill has tobe able to cut the material away very freely. Consistency in tool life means drill suppliers get a high-ly predictable number of holes for any particular applica-tion. ԓIf youre trying to get...

Holemaking PCD going all the way across, you have full production.You dont experience the usual wear, and you can run thedrill longer.ҔKennametal also plans to introduce at WESTEC anenhancement to its KSEM modular drills, which will add achamfering collar or ring to the replaceable carbide-tippeddrills. The chamfer collar will slide over the drill's steelbody, enabling users to save cycle time. Coolant-through drills helpreduce the tremendous heat gener-ated in drilling operations. Lastyear at IMTS, Iscar Metals Inc.(Arlington, TX) introduced a new ChamDrill Jet coolant-throughdrill that...

Holemaking insert which, to the best of my knowl-edge, is the first time anybodys donethat on a drilling insert.ғDue to the fact that the coolantscoming right into the end of the car-bide itself, all indications are that itҒsgiving us much better tool life, headds. ԓIts getting coolant right down to the cutting edge, and weҒre also seeing much better sidewall finishes because were able to flush chips outmuch more effectively. It also appearsto be produce something like a refrig- erating effect as the coolant goes through the carbide, so it keeps the carbide cooler when drilling materials...

After drilling, many other common holemaking opera-tions require boring and tapping of threaded holes, partic- ularly in aerospace and automotive. KPT Kaiser Precision Tooling Inc. (Elk Grove Village, IL) recently updated its line of boring systems with the new 112.118 Full Bore boring head toolkit for high-precision boring. Aimed at companies ranging from small shops through larger manu-facturers, the boring-head toolkits include two boringheads, two KAB shanks, insert holders, reduction bush- ings, and accessories. They offer shops precision and rigid-ity without the need to buy a large...
