<strong>The</strong> <strong>Original</strong> <strong>High</strong> <strong>Performance</strong><strong>End</strong> <strong>Mill</strong> for <strong>Aluminum</strong>Design FeaturesCircular Land – One of theunique features of the <strong>SGS</strong> Ski-Carb® end mill design is thepolished circular land. Tight controlof the circular land width reducesedge aggressiveness, which allowsthe user to vary speed and feedrates, as well as mill into cornerswithout inducing the chatter typicalto conventional tools.Ski-Land – Another unique featureof the <strong>SGS</strong> Ski-Carb® end mill isthe primary/secondary flute wallconstruction. Ski-Land is beneficialin avoiding chip interference bydirecting the chip away from thesecondary flute.<strong>High</strong>-Helix – <strong>The</strong> 45 degree helixangle increases effective rake forgreater shearing ability withoutreducing edge strength. It alsohelps elevate the chip up and awayfrom the work area.Stub Length – <strong>The</strong> <strong>SGS</strong> Ski-Carb®is available in short flute lengthsfor increased rigidity in the mostdemanding rouging applications.Corner Radii – <strong>The</strong> entire <strong>SGS</strong>Ski-Carb® line is available with acorner radius to provide additionalprotection against chipping.Versatility of <strong>SGS</strong> Ski-Carb®<strong>The</strong> <strong>SGS</strong> Ski-Carb® end mills have been proven winners for rough and finishmilling applications in aluminum, plastic and other nonferrous and non-metallicmaterials. <strong>The</strong> combination of unique patented* features, blended with availableoptions, provides customers with unsurpassed versatility, making the purchase ofseveral tools unnecessary to complete the job.<strong>The</strong> <strong>SGS</strong> Ski-Carb® offers the following enhancements: stub lengths forincreased rigidity in the most demanding applications; corner radius geometry foradditional protection against chipping; neck options on stub length shanks forextended reach capabilities; and, set screw flats.A wider range of feeds and speeds are possible with the exclusive <strong>SGS</strong> Ski-Carb®design to increase your production rates and improve your productivity. <strong>The</strong> <strong>SGS</strong>Ski-Carb® end mills give you clean, easy shearing action for chatter-free workfinishes, better workpiece tolerances, and significantly longer tool life.Features/Benefits• Patented Design Offers:- <strong>High</strong> Feed Capability- Superior Surface Finishing- Chatter Free Operation• Utilizes Maximum Spindle Speeds- Proven <strong>Performance</strong> at 50,000 rpm• One-Step Roughing and Finishing• Stub Lengths for Greater Rigidity• Popular Corner Radius Sizes• Neck & Flat OptionsSKI-CARB® <strong>End</strong> <strong>Mill</strong>s <strong>Performance</strong> Data<strong>High</strong>-SpeedSteel <strong>End</strong> <strong>Mill</strong>s3,000 rpmSki-Carb<strong>End</strong> <strong>Mill</strong>s10,000 rpmSki-Carb<strong>End</strong> <strong>Mill</strong>s50,000 rpmGreater Production RatesOperation: Profile <strong>Mill</strong>ing,2024 <strong>Aluminum</strong>, 1/2-inch diameter end millsMachine: CNC Vertical <strong>Mill</strong>.18*2405000 100 200 300 400 500 600Feed (Inches / Minute)Met Cut recommended speed/feed for aluminum** U.S. Patent No. 5,049,009<strong>SGS</strong> Ski-Carb ®Surface Finish Comparison1/2-inch diameter6061T6 <strong>Aluminum</strong>10,000 rpm/225 ipm.200 radial width x .625 axial depth11Lower Ra = smoother surfaceStandard 1370 25 50 75 100 125 150Ra (micro Inches)Roughing and Finishing Operations with a Single Pass – <strong>SGS</strong> Ski-Carb® provides a surfacefinish better than a finishing tool with the metal removal rates of a roughing tool!WWW.<strong>SGS</strong>TOOL.COM 27
