Niagara Cutter N56017 Carbide Ball Nose End Mill inch TiAlN Finish Roughing and Finishing Cut 30 Degree Helix 4 Flutes 1.5 Overall Length 0.063 Cutting Diameter 0.125 Shank Diameter

I have a couple of rotary tools and enjoy carving with them, however, the majority of burrs and cutters for them leave a lot to be desired so I decided to give some carbide ball end mills a try. Best decision I ever made with regard to these tools. The end mills I like are 4 flute and small to very small. These cutters give an extraordinary cut quality compared to what are generally sold as rotary tool cutters. These are extremely sharp, precise and cut cleaner than anything else. Of course this is not what these mills are meant for, which is a pity. If more people knew of these cutters, wood engravers all over would be a lot happier.I have been able to draw detailed organic and geometric shapes and replicate them very cleanly with these cutters, either freehand or using a mini router base with my Proxxon. The level of precision is really good because these cutters don't try to wander too much. Having four sharp flutes and a round tip put these cutters in a class of their own for wood engraving/carving.

If you want high feed rate, no deeper than half the width!! If you want a deep cut, prepare to go very slow!! I'm not meaning this as a bad thing, but it will not tolerate mistakes and will snap off with a great deal of ease. Watch your feed rate and depth and the cutter is wonderful to work with. Excellent chip ejection and appears to hold its edge well.Very few end mills this thin have such a long cutting length so this is one of those tools you absolutely need in your toolbox but it also demands a great deal of respect.

This is a great small End Mill used it to cut Titanium, worked very good cut clean and no change in performance after a lot of cutting.

As with anything you get what you pay for and this is no different. This bit is more then acceptable for lighter weight woods like plywood but harder woods the bit did dull on me faster then expected. I use it on a Shapeoko v2 with the upgraded DeWalt DWP661 motor to mill letters and numbers for reference. That being said for a hobbyist like myself I found this bit to be ok for basic engraving on wood. The bit removed all the material from the area cleanly and with a vacuum attachment was a very clean cut result. I would purchase again as needed for my lighter weight projects based on the price.

This bit is junk. I purchased it because I wanted the extra length for my cnc..My other bits only have an OL of 1 1/2 to 2 inches. And a cutting length of anywhere from 3/16 to 1/2. I was planning on doing a 3-d carving and would need to the extra length for the board. I use a lot of 1/16 to 1/8 ball nose bits..And when I run those bits, I use an FRO of 15-20% and a step over of 8, which is way less than half the bit diameter..This junk didn't even get that far..I was going to test it out on a piece of poplar..FRO was set at 20% and as soon as the bit touched the board it snapped..None of my other bits with those diameters running on these settings have any issues...Will definitely not be buying anymore of this garbage..

Performs well, exactly as described

We bought this bit to widen holes in a product. It ended up making over 1,000 small cuts and held up very well.

Nice bit for the price. No issues
