SE-4 Flute Solid Carbide Super Variable Helix End Mill Nano-Tek coated

In early 2011, Piranha USA introduced the world to the new Nano-Tek coating. Since that time the Piranha high Performance Carbide End Mill product line has taken the industry by storm. Based on the incredible feedback and overwhelming response received from the original  Piranha USA All purpose Nano-Tek carbide end mill High performance Carbide End Mill, Piranha has begun to expand their modest product line. 
In September of 2013, Piranha USA introduced their new Solid Carbide Super Variable Helix End Mill with the Nano-Tek coating. Just like the original Piranha All Purpose Carbide end mill, the Piranha Super Variable Helix End Mill will leave you with that incredible mirror finish, unlike any other carbide cutter on the market. In addition, The Super Variable Helix End Mill, with its state of the art Variable Index, Hi-Helix geometry design, is now available in square end or ball-nose style. Just below, we have included just a few of the Reviews/Testimonials that the Piranha High Performance Carbide End mill Series has gotten.

 Features & benefits:

  • High Performance in Peripheral and Finish Milling
  • Variable Helix and Offset Index Reduces Harmonics and Vibration for Faster Speeds and Superior Surface Finishes
  • Roughing, Slotting and Finish Milling
  • Achieve incredible Speeds and Feeds when Milling Steels, Stainless, Cast Iron, Inconel, Titanium Alloys, and High Temp nickel based alloys
  • Standard corner radius included
  • Available in Square End and Ball-Nose
  • Available in standard and stub length


Customer Testimonials:

“I use the Piranha end mills and have found them to be a very good efficient end mill the tool life is really good and the they hold up to many different types of materials. I always get great service from Midwest and Its nice to have a USA made end mill that will save me on tooling cost”
Brad-Shop Foreman–Automated MFG
“Thank you so much for introducing me to the 3 Flute Zrn coated Piranha Hi-Helix Carbide Endmills. Ive tried YG, Hertel, and even Dura-mill and can honestly say that these Piranha ZRN coated Carbide Endmills put them all to shame. I now get 3 x the tool life minimum, and I am able to easily max out my feeds and speeds with no worries. The very first time we ran the new Piranha Aluminum Streaker Mill our work piece production jumped from 126 parts to 341 pieces which literally blew me away!!”

Thank you midwest industrial tool
I just got the tools. Thank you very much! That was very nice of you, we love the quality of the tools you sell. Knowing that they are made in the U.S.A, gives us the pride in our country that we all need in these shaky times. With your help, I was able to increase my production overall by 21% on my tough to machine parts! The new Nano-Tek Coating is awesome! I use the 1/8 Nano-Tek end mill, in 625 Inconel with no worries. Full width of cutter, .050 deep by .700 long. Using this cutter in steps of .010 at a time I cut over 120pcs in a 8 hour shift. Our production on that part before was 6.5mins, after it was down to 3.75 mins! Again, thank you Midwest Industrial Tool for making my life easier, and helping me grow my profit line! One happy customer, Anthony-Production Manager AG Geophysical Products

Piranha Variable Helix End mills
Don't normally take the time to do this, but in this instance its well deserved. I just have to say that ive been machining for almost 30 years, and i have NEVER come across an endmill this good. I was able to almost double my feed rate and max RPMS while cutting Titanium. For anyone out there that works with titanium, you understand how impressive this is..Glad i broke down and tried a few!!!

Pretty decent cutter
Using hannita varimills right now...Worked good, but i didnt notice too much of a difference on stainless....They are however about 30% cheaper than hannita vari-mills...I would recommend these cutter
