Carbide.What do Masonry Drills have on the tip?.
There are still plenty of good pillar drills made but the quality is reflected in the price.As for Pillar drills, if it's not 40 / 50 years old it's not very good unfortunately.
By which you mean, think of a number, add a few hundred, then triple it!Carbide.

Just got the 99 piece cobalt kit from uk drills, will see how I get onI had an lld Aldi workzone drill press I used for our RC trailer when we raced.
Not very strange but I need to mount a jig to hold some 30mm steel cage clamps. And I needed an extra drill to see me changed the jig..
Some 4.5 Cobalt drills from UK drills and I was amazed they lasted for hundreds of holes at a time.
I did change one or two during the time we had the job running but they seemed to cut no better when new. I was amazed at their longevity.
Using a dealt 18 volt better drill took probably 10 times longer to get through each hole.
I did use a wind up old style scissor jack under the table to stop it flexing but would not hesitate buying one again if i need a small pillar drill.
