Looking for an end mill with unsurpassed performance in high-efficiency milling of Titanium? The new Fullerton 3116 TiMill end mill may be just what you need. Titanium is half the weight of steel and twice the strength of aluminum: It's a high strength, light weight material with excellent fatigue performance, super durable in high stress environments and corrosion resistant. As a result of titanium's material properties it's making it become evermore popular in the aerospace, defense, shipbuilding, medical adn dental industries. It's also what makes it considered a "more difficult to machine" material. Let's dig into that a bit more.
The trick to machining titanium has always been to keep consistent coolant flow to evacuate the chips and maintain a consistent chip load. Again, rough to your finish size. Don't let it work harden. That's what we've learned about titanium over the past couple of decades. There has been a ton of research on titanium's properties and that research has led to further refinement of the cutting tool geometry at Fullerton. The design of Fullerton's 3116 TiMill is based upon over a decade of aerospace testing and developmentand addresses many of the machining issues that Titanium presents. It's a 6-flute tool built with a 38°helix. The increased number of flutes allows for the tools to remain "in the cut" longer and more consistently. It doesn't induce as much heat as a lower number of flutes tends to do. instead, it's consistent. The 38°helix evacuates the chip at a more optimum angle than a 35°, 37.5° or 40° helix that predecessors made by competitors have tried.
It has an extremely high hardness, toughness and heat resistance which makes it ideally suited to keep the heat out of the core cutting tool in titanium applications. The 3116 TiMill 6-flute high-performance 38°helix end mill is stocked with FC-13 coating. Speeds and Feeds are Critical* IT'S MADE FOR TITANIUM! So that means it is NOT Recommended for High Si Aluminum (>10%), Low Si Aluminum (<10%), Composites, Plastics, Brass & Copper, or Graphite. NOT Recommended! Choose your Size
