7 Pieces Center Drill Bits Set, M2 High Speed Steel 60-Degree Angle Center Drill Bits Kit Countersink Tools for Lathe Metalworking Size 1.0 1.5 2.0 2.5 3.0 4.0 5.0

This set of center finders covers all sizes of countersinked pits in my project work pieces. They are extremely accurate and durable for a good price.

The product was just as advertised and arrived quickly. Good experience

Small bits have a tough time in brass and don't work very well in steel. The bigger bits work great in everything though. Hog through metal with ease and leave a clean cut.

I believe this is a good deal for the price. The quality is good.

I have only used one of them so far but it was very sharp and cut very well. For the novice machinist out there, keep the speed slow and and keep the bit cool, take your time and you should be able to drill the hole you need. This was a great bit to start the hole in the spot I wanted without any of the flex from a long drill bit that you normally will get.

Not as finished as in the picture and the outside/inside of the plastic case had greasy fingerprints. The bits look in good shape, but time will tell how well they work.

I haven't used them yet. The tools seem well made, sharp, and well finished on a quick initial look.

I did not buy thees for their intended use. I use center bits for starting a pilot hole in certain metals, wherea regular twisted bit tends to bend a little when first started causing some inaccuracy problems, especially with thin sheet metal. Otherwise, these bits do my job for me.
