1 B011G High Power, Corner Radius, Medium, 4 flute Great for Difficult-to-cut materials like stainless steel, titanium alloy and inconel. adue to high helix angle and newly designed corner radius, it is suitable for milling difficult-to-cut materials like stainless steel, titanium alloy and inconel.

2 MIRACLE END MILLS Miracle High Power Corner Radius Endmill Great for difficult to cut materials. Stainless steel, titanium alloy, inconel In case of milling hard-to-cut materials like stainless steel, titanium alloy and inconel at Aviation or Dynamo industry, due to the new geometry with suitable helix angle, cross section and corner radius design (*1), high efficient milling is made possible. (*1:PAT pending) Low cutting force and good chip disposability realized by high helix angle. Newly designed corner radius Adopting long shank. yfeature Cutting force is reduced by adopting original geometry profile. znewly designed three geometry profile is applied to the part of corner radius. xcutting force is reduced by adopting original geometry profile. The chip flow is very smooth and long tool life is made possible. 1

7 SAFETY OF CUTTING TOOL PRODUCTS y Packages of Mitsubishi products carry a safety warning label. However, tools are not labeled with detailed warning indications. Please read the "Safety of Cutting Tool Products" in this catalogue before handling cutting tool products and cemented carbide materials. Moreover, as a part of your workers' safety education, please notify the contents of the "Safety of Cutting Tool Products" to all workers. y 1. Use of Cutting Tool Products. Basic Characteristics of Hard Tool Materials ain Terms of "Safety of Cutting Tool Products" Hard Tool Materials : General term for tool materials like cemented carbide alloy, cermet, ceramics, sintered CBN, sintered diamond, high speed steel and alloy steel, etc. aphysical Characteristics Appearance : Varies depending on the type of material. Eg. grey, black, gold, etc. Smell : None Hardness, Specific Gravity : Hard Tool Materials High Speed Steel (HSS) Cemented Carbide Cermet Ceramics Hardness (HV) Specific Gravity Hard Tool Materials Hardness (HV) Specific Gravity kg/mm kg/mm kg/mm kg/mm Sintered CBN Sintered Diamond Alloy Steel Diamond Electroforming Product kg/mm kg/mm kg/mm kg/mm aconstituents Carbide, nitride, carbon nitride, oxide, such as W, Ti, Al, Si, Ta, B, V and metals such as Fe, Co, Ni, Cr, Mo. y. Safety of Cutting Tool Products uhard tool materials have a large specific gravity. Thus, they require special attention as heavy materials when the size or quantity is large. ucutting tool products generate dust and mist during grinding operations or heating. This dust and mist can be harmful when coming in contact with the eyes or skin, or if substantial quantities are swallowed. When grinding and machining, it is recommended to use local exhaust ventilation and respirators, a dust protective mask, glasses, gloves etc. If dust makes contact with the hands, thoroughly wash the affected area with soap and water. Don't eat in the exposed area, and wash hands thoroughly before eating. Remove dust from the clothing by a cleaning or washing, but don't shake off. ucobalt and nickel contained in carbide or other cutting tool materials are reported as possibly carcinogenic to humans. It is also reported that cobalt and nickel dust and mist can affect the skin, respiratory organs and heart through repeated or prolonged contact. ufor further information, please refer to MSDS (Material Safety Data Sheet). Home page: y 4. Handling Cutting Tool Products usurface conditions affect toughness of cutting tools. Therefore, use a diamond grinding wheel for finishing. uhard tool materials are extremely hard and brittle at the same time. Thus, they may be broken by shocks and tightening with excess force. uhard tool materials and ferrous materials have different thermal expansion ratios. Shrinkage or swell fit products may suffer from cracks when applied temperature is higher or lower than the appropriate temperature for the tool. upay special attention on storing hard tool materials. Toughness of hard tool materials is lowered when they corrode due to coolant and other liquid. uwhen brazing hard tool materials, if the temperature is too high or too low from the melting point of the brazing material, loosening and breakage may occur. uafter regrinding cutting tools, make sure that there are no cracks. umachining hard tool materials on EDM may cause cracks on the surface due to electrons remaining after the EDM operation, resulting in lowering of the toughness. Eliminate these cracks by grinding, etc. 6
