Hello, Is there or can anyone recommend an Endmill bit of 75mm or longer full length? I am cutting 60mm+ material which needs to go down A very deep groove. Thanks,
Kodiak Cutting Tools has some extended reach endmills. They are what I used when I needed longer length endmills. Here are two, but there are others with varying cutting lengths. 4 inch long 2-Flute Carbide End Mills | Solid Carbide End Mill Bits 6 inch long 2-Flute Carbide End Mills | Solid Carbide End Mill Bits
What are you seeing that leads you to believe this? Maybe an international internet or shipping limitation? They are readily available on Amazon in the US https://www.amazon.com/Kodiak-Cutting-Tools-KCT137388-Premium/dp/B007BTQ502. Amazon UK carries a far more limited collection which does not appear to include this size.
Rennie Tool do an extra long series 6mm carbide bit - 150mm overall: Solid Carbide 4 Flute Long EXTRA Long Series TiAlN Coated Endmill (End Mill) | eBay I've bought a few bits from them (not that particular one) and they've been OK.
I was able to go to that link I posted, add one to my cart and proceed to the checkout. I did not follow through with a purchase though because I do not need one. It all appeared to work. But I am in the U.S. I did not see you are from the UK so that may not make it cost effective.
