This is what I found out about Daniels drill bits, when I first received them I did a pretty thorough inspection, All of the uncoated bits were clearly marked, the only problem I noticed and that actually didn't appear at that time was there was no mm. designation. I was my fault for not considering that the drill in question was metric and not numeric.
The Tin coated bits had some trouble on the cutting lips, as there was some light burring on the inside toward the web, these burrs knock off very easy with a round die stone. and On the drills I was sent the markings were very light on the Tin coated drills compared to the bright finish HSS bits. The quality of the ground surface of point was a bit too coarse, when compared to some new Cleveland Twist Drill company drills I had received about the same time,
This doesn't present any real problem other than cosmetics and a very remote chance of building up heat,. I first used the ½ inch HSS I put it in a CNC lathe and started drilling mild low carbon steel, (1018) I drilled a total depth of 31 inches in various pieces of scrap 1 inch round stock.
I was surprised with the drills cutting ability, the chisel point was very close to center, the margins were good and sharp, the first 10 pieces which were drilled between 1.5 and 2 in deep were close to being with in .002 being .5012 to .4985, it cleared its chips well and performed far better than expected.
The 7.mm was the next drill I used also a regular HSS bit. Drilled in Polyester Resin dead on center drilled a clean round hole, I drilled 5 sets of blanks, all were within .0015 on wood, Paduk, and Ironwood and Ipe it was pretty easy drilling, the Ipe and PR the drill bit did get warm, I may have drilled a bit fast on the PR the Ipe is just hard to drill.
I drilled a piece of Ironwood with the letter X drill, nice true hole also drilled a piece of Olivewood, both holes were clean and round . I haven't tried any of the other drills yet, but "these drill bits are far better than the Harbor freight set or the import sets from Enco,"
They are good drill for the money, I saw somewhere a ridiculous price posted for a larger bit 12.5 or 13.3 but I can buy OSG coolant through drill bits for much les than the 200.00 shown, these are not going to hold up as long as a Chicago Latrobe, Cleveland Twist drill co. or OSG or Onsurd, But you aren't paying the double to triple or more for these drills either, I know Daniel is wanting feed back on the bits he sent me but these are the only ones I've used I will be drilling more blanks this week and will drill some more steel scrap as well.
In My opinion as a person who relies on quality tools for a living, these would be marginally adequate, For just drilling good true straight holes in Wood, Acrylics, Aluminum. They are a very good drill bit,
