Amana tool 51753 Mini Solid Carbide Spiral for Steel, Stainless Steel & Composites, AlTiN Coated 0.0125 Radius x 0.025 Dia x 0.075 Cut Height x 1/8 Shank x 1-1/2 Inch Long Up-Cut 4-Flute Bal End Router Bit/End Mil

2 & 4 Flute High Performance Ball End Mini Mills Solid carbide spiral up-cut ball end mini mill router bits, designed for micro applications. Perfect for the signmaking industry. The special carbide grade combined with the Aluminum Titanium Nitride (AlTiN) coating gives amazing performance. Choose 2 Flute endmills for efficient vertical plunging, pocketing and slotting operations. 4 Fluted tools offer the promise of improved surface finishes, longer service life and increased feed-rates with peripheral milling applications. Micro machining applications involve miniature tooling that requires very high attention to tolerances and detail in their construction. These end mills incorporate 30 degree helixes and AlTiN coating to insure a high degree of precision. Miniature end mills also routinely require RPMs in excess of 40,000 RPMs or more, so attention to both RPM capacity and accurate chip-loads is mandatory. Excellent for use in a broad range of materials including: Stainless Steel Steel Titanium Cast Iron Cermet* Magnesium Plastic*Cermets are composites in which ceramic materials and metals join together. AlTiN Coating Benefits: Extra wear resistance Allows for faster feed and speed rates Cutting edge protected from wear Better chip evacuation Less heat build up Superior cutting quality and extended tool lifeWARNING! Due to the extremely small diameters involved, please exercise caution to the accurate calculations of all feed and speed rates. Inspect cut quality and adjust feed and speed accordingly. Care should be taken to observe proper feeds and speeds according to the workpiece material to avoid damage.Note: For optimal results and extended tool life use mist lubricant system or air cooling.
