Amana tool 51725 Mini SC Spiral for Steel, Stainless Steel & Composites, AlTiN Coated 0.040 D x 0.120 CH x 1/8 SHK x 1-1/2 Inch Long Up-Cut 4-Flute Square End Router Bit/End Mil

2 & 4 Flute High Performance Square End Mini Mills Solid carbide spiral up-cut router bits/end square mini mills, 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 thatrequires very high attention to tolerances and detail in their construction. Theseend mills incorporate 30 degree helixes and AlTiN coating to insure a high degree ofprecision. Miniature end mills also routinely require RPMs in excess of 40,000 RPMsor more, so attention to both RPM capacity and accurate chip-loads is mandatory. Excellent for use in a broad range of materials including: Stainless SteelSteelTitaniumCast IronCermet*MagnesiumPlastic*Cermets are composites in which ceramic materials and metals join together. AlTiN Coating Benefits:Extra wear resistanceAllows for faster feed and speed ratesCutting edge protected from wearBetter chip evacuationLess heat build upSuperior 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.
