It does not produce chatter or an odd triangular countersunk recess

I dont think this is really meant for steel

I used it for about a dozen holes and its chipped out on one side

Have to be careful when using too much pressure and you end up with a deep hole

I wish it had a longer shank as when you use it on a drill press to csink a hole its often too short compared to the bit and you have to raise the table which loses the centering youd like to have to make sure the hole is concentric
