“Going to all costs” doesn’t always mean you have to spend more.
We can all agree scrapping parts is always a bad thing, but scrapping extremely expensive parts is even worse. Our customer was machining air-cooled heat exchangers that cost $15,000 each. Needless to say, they were going to all costs to make sure the parts were right the first time.
But going to all costs doesn’t mean you can’t find other ways to decrease your costs.
The high penetration drill they were using worked well, but with a hefty price tag on the replaceable insert, they wanted to reduce their drilling costs. The customer decided to test the 4TEX Indexable Carbide Drill with inserts that cost 81.54% less. Using the 4TEX “M” geometry inserts-designed to produce excellent chips in ductile materials and improve tool life in heat resistant materials-the customer was thrilled with the small chips and equal hole quality.
With the previous drill, the customer achieved 30 holes of tool life before needing to replace the insert. Utilizing the 4TEX four-sided insert design along with the “M” geometry’s heat resistant coating, they achieved 100 holes of tool life before replacing the inserts.
With insert cost savings of 94.5%, the switch to the 4TEX Drill was a no-brainer for the customer. Just because a part is expensive doesn’t mean it also needs to cost more to machine.
