Anyone ever bought any end mill cutters from enco and had good results? If so what brand and type? Looking for some decent ones for aluminium and steel. Thanks

I have bought both TiN coated and HSS. Had what you could call good luck. Just watch your feeds and speeds and keep work temps down and they will be OK. I wouln't recommend them for Hi-speed production type work but for a few cuts here and there they will work.

don't buy their brand because they are cheap china made but they also sell good quality made in usa mills and tool bits that i have had real good luck with and they have pretty good prices on them

You get what you pay for regardless of who you get them from, but even good quality tooling won't last if not suited for the job or run at speeds and feeds it's not intended for. As far as buying from Enco is concerned, I have done business with them for years and every experience has been positive. Great customer service.

Use 2 flute for alum. and 4 flute for steel. If you don't use alot of coolent none of them will last. I have bought from Enco for a long time. MACK

On aluminum a 2 flute high helix works best. If you are just using a manual mill for simple machining spray WD40 on the end mill ever so often. It works amazing to keep the aluminum from sticking to the end mill. For CNC machining a oil based water soluable coolant is what I use. Like stated above Feeds and Speeds are your best friend for making an end mill last. As far as brands go.. Spend the extra money and get USA brand..

You may want to buy some inexpensive end mills to learn on if you are just starting. Cheeper to break a cheeper one than a expensive one. MACK

Pay attention to which way you feed into the material. If you feed in the direction that the cutter wants to pull itself deeper into the workpiece and you have an older machine that has backlash in the feed screws it will grab and jerk the table toward the cutter. Then you will have a broken cutter.

We have always liked dormer products. Not cheap but good is HSS. In the end insertable carbide is where you will end up when you get going.Smiling
