Very nice bits to go with small power carving tool

I use them on Mild Steel and Aluminum. If you go into your project knowing it will take some time and don't lean into these bits with too much pressure their Great. As soon as you rush or lean into much, they will dull out on you. I only wish Amazon offered the other two sizes Micro-Mart offers on their site.

Although the cutting heads are almost too small for me to see clearly without my reading glasses, they cut very well. I was just doing detail work in some rosewood and they were doing great.

Great product and quality for the price. Is exactly as described. I definitely recommend.Just FYII've been using them at around 10-15k rpm with lubricant, and have had absolutely no issues with very minimal to no wear after several hours of use.

No hassle transaction, the way it should be -- recommend

This item was used to carve a wax ring in preparation for a cast setting. The 2 bits broke within one hour of using them. This item wasn’t even used on metal and it still broke. I have no idea why this item was reviewed so high the quality just isn’t there.

Love the detail I can now do. Great bits
