NEWS Solutions for stainless steel, super alloys and titanium The challenge Difficult-to-machine metals are a broad field and depending on the material comprise a wide variety of machining difficulties. These go from long chips and tough/elastic behavior to poor heat conduction and extreme hardness. This is a special challenge for cutting tool users in general and tool suppliers and machine operators in particular. In spite (or simply because) of such properties, these metals are readily used in demanding industries, that is, everywhere where the material is exposed to extreme conditions. This is therefore about properties such as heat resistance, corrosion and acid resistance, biocompatibility, low weight but high degree of strength, good formability or even high degree of hardness. The characteristics ■ Stainless steel (rustproof and acid-resistant steels): corrosion and acid-resistant, high degree of toughness, low thermal conductivity (depending on composition), good formability. ■ Titanium: high degree of stability at low density (hard like steel at approximately half the weight), corrosion and temperature-resistant, biocompatible, good tensile strength, high degree of toughness, low thermal conductivity. ■ Superalloys (HRSA = Heat Resistant Super Alloys): high degree of strength and hardness even at high temperatures; corrosion, acid and heat-resistant. Low thermal conductivity. ■ CrCo alloys: biocompatible, minor heat expansion (like ceramic), corrosion, acid and heat-resistant, high degree of hardness. The solution To be able to offer an efficient solution for machining even in small diameters, a solution that actually earns the addendum "best suited for difficult-to-machine materials", Mikron Tool has incorporated different factors in tool development as geometry, cooling system, solid carbide, coating and a clearly defined machining process. 4

DRILLING TOOLS CRAZYDRILL COOL SST-INOX NEW CrazyDrill Cool SST-Inox 10

DRILLING TOOLS CRAZYDRILL COOL SST-INOX NEW DEEP HOLE DRILLING OF STAINLESS STEEL & CO. IN ONE STEP What's new: CrazyDrill Cool SST-Inox is now also available for drilling depths of 30 x d and 40 x d. This drill has been specifically developed for rustproof, acid- and heat resistant steels as well as for CrCo alloys. Previously unreached performance is now possible based on a new cutting edge geometry and a new coolant duct shape, which provides massive cooling of the cutting edges. The new high performance coating is wear resistant and assures continuous chip evacuation. The features: The bore up to a maximum depth of 40 x d is performed in a single feed stroke. Thanks to the new cutting edge geometry and the flute profile optimal chip breaking and chip evacuation are guaranteed. The newly conceived helical, drop shaped coolant ducts deliver the highest coolant effect (one to four times larger coolant quantity reaches the tip of the tool, compared to round shaped ducts). Hence better feed, speed and tool life are guaranteed. Diameter range: 1 mm to 6.35 mm Drilling depth: 6 x d, 10 x d, 15 x d, 20 x d, 30 x d and 40 x d Coating: eXedur SNP www.mikrontool.com 11

The result is continuous and efficient chip removal as well as constant and substantial cooling of cutting edges. A Powerchamber additionally guarantees sufficiently strong coolant flow for smaller diameters up to Ø 2.95 mm. 3 | C ARBIDE A specially developed micro-grain solid carbide allows machining at high speeds. 4 | N EW COATING The high-performance coating eXedur SNP is heat-resistant and wear-resistant, prevents build up edges and promotes uniform chip flushing. A very long tool life is given. 5 | NEW CHIP FLUTE PROFILE Divided into two areas: ■ Front chip flute area: a special chip breaker shape ensures compact, short and curved chips. ■ Rear chip flute area: an extended flute shape ensures perfect chip removal. 6 | POLISHED FLUTES The polished flutes in versions 15 x d, 20 x d, 30 x d and 40 x d promote uniform chip flushing. 7 | DOUBLE GUIDING MARGIN The narrow guiding chamfer ensures the highest degree of precision (straightness) and surface quality.
