Not better than TEMO Keyless Chuck Adapter 1/4" HEX SHANK to Conventional or Micro-size Drill bit. I bought BOTH YESTERDAY, and received them today with Amazon Prime 1 day shipping. I am using a 1.05mm Cobalt (not Carbide) drill bit(s) I bought from McMaster-Carr, and let me tell you again, because even though this is #1 Best Selling "IT IS "NOT BETTER" than the Neiko 1/4-Inch Keyless Chuck Conversion for Power Tools. Don't get me wrong, it works very well, and it can hold "tiny" drill bits, but the Neiko 1/4-Inch Keyless Chuck Conversion for Power Tools can hold SMALLER drill bits and and in my honest opinion, the Neiko 1/4-Inch Keyless Chuck Conversion for Power Tools is better quality. They BOTH DO NOT WOBBLE. If you're wobbles or if other people on here that wrote that it wobbles or whatever you want to call it, THEY ARE WRONG. I am drilling 1.05mm (0.04133858") holes (Freehand, no Drill press) into Wear-resistant A2 Tool Steel, Tight-tolerance Rod, 5/64" which is about 0.0781" or 1.9844mm diameter A2 Tool Steel rod for a coil jig I'm making to make very nice coils for RDA's (Rebuildable Dripping Atomizers). I gave this 4 Stars because... 01. It DOES NOT WOBBLE. 02. It WORKS with tiny drill bits. (1.05mm). 03. Well made.. kinda.. I gave this 4 stars because it WORKS with tiny drill bits. It also seems that IT WILL WORK with smaller drill bits, but it also seems that the jaws do not meet all the way like the TEMO Keyless Chuck Adaptor 1/4" HEX SHANK can and does. I am using a prick punch I bought from Amazon as well, which is "Starrett 816A Prick Punch, 4" Length, 5/64" Tapered Point Diameter", which as you probably have figured out, that using a "PRICK PUNCH" not a center punch, that it makes my job much easier. The "Heat-resistant Cobalt Steel Jobbers Drill Bit, 1.05mm, 34mm Oal, 9.90mm Drill Depth,135 Deg Point" I'm using that I bought from McMaster-Carr is too large, lol.. go figure.. for the tiny dent the prick punch creates in the tiny 5/64" A2 Tool Steel rod I'm working on. So I just went to Lowes Home Improvement Store tonight and got a IDK.. cant' find the receipt, but it's a scratch scroll for making marking on metal and it also can be used as a center punch. it's quite large, but it's got a nice point on the tip for making that dent the prick punch makes a little broader. I've drilled 3 holes so far, in 3 length of that 5/64" A2 Tool steel, and have not had any WOBBLING or anything like that.. I'm not saying do not buy this, because IT DOES WORK, it's just not as smooth as far as the inner workings on this compaired to the TEMO Keyless Chuck Adapter 1/4" HEX SHANK to Conventional or Micro-size Drill bit. Imho, this is 2nd best and the TEMO Keyless Chuck Adapter 1/4" HEX SHANK to Conventional or Micro-size Drill bit should be the best selling item on Amazon. It's probably Best Selling because it came on Amazon first or something idk.. Thats my review, and I'm sticking to it.
