30° Helix center cutting 2 and 4 Flute End Mills Used for: Side Milling, Open End Slot Milling, Plunging, Open End Slot Milling, and Closed End Slot Milling Neck Diameter is Reduced 0.020" on all sizes for required clearance in long reach applications Made in USA Coated Aluminum/Tin for extended tool life

The MICRO 100 GLR-312-4X AlTiN - Aluminum Titanium Nitride coated, 4 flute, 30° helix, reduced neck, long reach, center cutting end mill. Designed and engineered with a reduced neck diameter for clearance in long reach applications. Can be utilized for semi-finishing and finishing applications. These high performance end mills feature a 30° helix with a conventional tool geometry that supports applications in a wide scope of different materials. AlTiN coatings are high performance and versatile. Has a higher breakdown temperature while maintaining high surface hardness at elevated temperatures. This type of coating also promotes tool life and allows for faster feeds and speeds. Excellent for dry machining applications. Applicable with oxidation temperatures up to 800° C or 1450° F. AlTiN coatings are best suited for alloy steels, stainless steels, tool steels, nickel alloys and titanium. MICRO 100 Solid Carbide Tools feature more than just a micro-grain of excellent quality. Their substrate is in class of its own resulting from exclusive treating processes that allow increased speed and feed rates. For over 45 years, MICRO 100 is a known industry leader and internationally acclaimed when it comes to solid carbide tooling.
