TOOLING AND WORKHOLDING Modern Machine Shop 121 A Member of the BIG DAISHOWA Group The Sphinx Phoenix TC2 high-performance drill excels in nearly all materials — including exotics. The advanced coating and geometry affords less heat on the tool and better chip flow and evacuation. Don't believe us? Test a Sphinx TC2 in your shop to see the proof. HIGHER PENETRATION RATES AND WE'LL PROVE IT. Visit to request your Sphinx Phoenix TC2 no-risk trial.

The system is a modular end mill with the performance of solid carbide. It uses a double-cone locating surface like that of the company's KM or KM4X tooling design so that radial runout values do not exceed 5 microns (0.0002"). The machine maintains Z-axis coupling repeatability of 10 microns (0.0004") or better. The system provides tool-to-tool repeatability of 50 microns (0.002"), preventing the need for offset adjustment or off-line presetting when changing tools. The system is rigid, with an intelligent coupling thread to absorb torque. These features enable 1×D full-width slotting cuts and side milling up to 50 percent radial engagement along its entire 1.5×D cutting length, even in titanium and similar high-strength alloys. This expansion more than doubles the existing cut- ting tip product offering. The variable Harvi helix design reduces chatter, even in difficult-to-machine materials, while an asymmetrical flute angle enables higher feed rates. The eccentric flute relief increases edge stabil- ity, providing a commensurate increase in tool life. A tapered core provides rigidity, and its axial and radial rake angles reduce tool pressure. The same tool can perform roughing and finishing, or users can utilize dedicated roughers and finishers in the same interface. Four- to six-flute versions are available, as are several PVD-coated micro grain carbide grades. These include KCSM15 for titanium and other high-temperature, aero- space-grade alloys; KCPM15 for steel, stainless steel and cast iron; and the multilayer KC643M for wet-cutting a range of materials. All grades can machine metals up to 52 HRC and are said to reduce depth of cut notching, edge wear and cratering in difficult materials. | Kennametal Inc. 800-446-7738 | Expanded Modular End Mill Series More than Doubles Options
