1: Material2: Coating3: Design4: Price Compare with these two Series, the quality of the Standard Series is better then the Economy Series.Economy Series is the normal products in DHF. We would like to suggest the upper level to extend the life length and work effective of end mill. 

Because Stainless steel has superior featured abilities of erosion, shapes, tolerance and tenacity, it has wide applications on heavy and light industry, supplies industry and architecture decorations.The most used stainless steels are SUS303, SUS304, and SUS316, because of their high ability on erosion and strong tenacity; it would have problem of radiation, material hardened, and chip stickness, those problems make it much harder to cut.In order to overcome the difficult features of stainless steel, the material, coating and geometry design are keys factors.1. For stainless steel cutting, not only well-executed and smooth of chip removal, also away with radiation, decrease the problem of hardened material.2. Most stainless steel milling takes wet coolant, the suitable coating is G10.3. High helix angle groove R and anti-vibration design; when high performance milling, the cutting speed Vc could reach to 100-120 m/min, and it is able to 1D machining for both slotting and side milling.Because the different demands of end mill selection to customers, here we have the  recommendations based cutter’s performance and life:First selection:        Second selection:     Third selection:        Written by DHF Technology Center

**5 Key Features of the Nickel-Based Superalloy Series:**1. Overcoming the challenges of machining Inconel 718 and Nickel-based superalloy, with excellent performance and tool life.2. Special geometry design with good rigidity and better vibration resistance during processing.3. The new composite G18 coating design with better wear-resistant.4. Vc value can reach 50 (m/min) and above, when machining Inconel 718 and nickel-based superalloy.5.After testing Inconel 718 by DHF Application Center, the tool life of "KSR" is better than major European brands.Explore Series

For the sake of environmental protection and resource preservation, DHF presents the Exchangeable series 1 in 2008.It extends the work effective and the life of the end mill; the head and the shank which makes it much easier to set up and strength the entire structure and rigidity.In order to provide the better service and strength, we had presented the Exchangeable 2 in 2010. I  Speciality:1.The combination of new model design of triple-thread head and shank, which makes it much easier to set up and strength the entire structure and rigidity.2.The superior combination of the triple-thread head end mill controls the  run out within ±0.008mm. The extremely high accuracy and slight run out relatively extend the toll’s life.3.In order to the environmental protection and resource preservation, the triple-thread head end mill saves more design materials and shortens the producing process,   which meets the purpose of reducing the cost for our customers.4.The combination of the threaded head end mill and hard alloy shank determines the large depths of cutting. Compare with the normal end mill, due to can switch head easily; exchangeable series can save more costs.  5.A special angle design and the brand new coating enable to work in hardness up to HRc62.II  Application:1. Combination setting：You can only use one shank but change different DHF heads for machining, and it is a big cost to save.2. New design：The product sizes are more completed. The dia. Of head is from 8mm~32mm, and the length of shank is from 60mm~300mm.    They are good at doing the large depths   of cutting and the regular cutting.3. The design of head is good at machining finishing and semi-finishing, and the tool’s life and surface clearance are all better than the disposable insert design.4.Our end mill field can be used from aerospace, auto mobile, mould and  so on, and the material can be cut from soft to hard. (HRc is the 3-62.)
