T O O L C O A T I N G G U I D E Tool Coating Guide Dura-Mill offers a variety of tool coatings to enhance the performance of our end mills, and has carefully selected the appropriate coatings for each end mill series. Many of our end mills are offered in a variety of standard coatings that are best suited for the intended purpose of the end mill application. Additionally, Dura-Mill offers a number of optional coatings that are available to further enhance our customer's requirements. STANDARD STOCKED COATINGS Coating Type Code No. Color Application Benefits C2 Blue-Gray Most ferrous, Non Ferrous Materials and Non-Metallic Materials. Excellent for interrupted cutting applications. High coolant volume is strongly recommended. TiCN Titanium Carbo-Nitride ZrN Zirconium Nitride C4 White-Gold Primarily used for Non-Ferrous Materials and Glass Filed Plastics. Extremely hard coating offers excellent wear resistance. Reduces friction and prevents galling. High shock resistance. Improves lubricity and tool life due to less adhesion on the cutting edges TiAlN Titanium Aluminum Nitride AlTiN Aluminum Titanium Nitride C5 Violet Cast Iron, Nickel Based and High Temp Alloys. Excellent for high speed machining. Run in flood coolant or semi-dry applications C6 Black All Ferrous Materials exceptional performance in Nickel Based and High Temp alloys applications. Excellent for high velocity machining. High hardness which offers excellent wear resistance. Reduces friction and prevents galling. Performs well in high heat conditions. Ultra-High hardness provides maximum tool life. Performs well in extreme heat conditions and may be used in dry or semi-dry machining environment. OPTIONAL COATINGS Amorphous Diamond (Tetrabond) C7* Black Suitable for Aircraft Aluminum Alloys, Graphite and Composite materials. Extremely hard coating offers excellent wear resistance. Very low coefficient of friction. * These coatings are available as a non-stock standard. Please contact our Customer Service Department for availability. 48

Select the largest tool diameter as possible to maximize tool life, tool rigidity and metal removal rates. Select the shortest length of cut as possible to further maximize tool rigidity. General Guidelines in Selecting and Optimizing End Mills Avoid excessive tool overhang to minimize tool deflection. Choosing the correct number of flutes is one of the most important factors to maximizing tool performance. Understanding the type of machining application in terms of depth-of-cut (slot, heavy peripheral, semi-finishing, finishing, etc...) is critical for selecting the proper tool. Choosing as many flutes as possible without sacrificing chip evacuation is crucial to optimizing metal removal rates. All Dura-Mill end mills are provided with precision ground shanks and may be used in a multitude of tool holding systems including shrink-fit type holders. However, when considering using an end mill type holder, Dura- Mill highly recommends factory ground set screw flats to ensure proper location for the locking screw. Dura-Mill will provide its customers with standard ground Weldon flats in accordance with the ANSI B94.19-1997 location, or to customer supplied specifications. Please call us for complete details. Altering tools without written authorization is not permitted and will void all product warranties. Climb Milling versus Conventional Milling E N D M I L L S E L E C T I O N G U I D E L I N E S On machine tools equipped with back-lash control, Dura-Mill recommends climb milling as opposed to convention milling. Climb milling enhances chip evacuation thus increasing tool life and improved surface finishes. Climb milling can be used in most milling applications and materials and is especially recommended for titanium, cobalt and nickel based alloys. Conventional milling is preferred when machining castings or forgings with rough surfaces and/or scale. 49

THEN MULTIPLY THIS FACTOR BY THE APPROPRIATE RPM. RESULT: FEED RATE PER TOOTH EXPRESSED AS IPM FORMULA: IPT X NUMBER OF TEETH X RPM EXAMPLE: 1/2 DIAMETER, 4-FLUTE END MILL WITH A RECOMMENDED FEED RATE PER TOOTH OF.0023 (IPT) AND A RECOMMENDED RPM OF 2865 (375 SFM) = 26.358 IPM TABLE FEED RATE. 51
