Review: Hex shank helps to stop bits slipping. Even small sizes are clearly marked. - Nice set of drills, that all have a hex shank for mounting. The bits come supplied loose in a cardboard box. I think a drill bit box would be a nice upgrade here, to contain and sort the bits more effectively. With Hex shank, if you change drill bits you just have to loosen slightly and tighten to swap them. And there is no danger of the drills slipping in your chuck, because you didn't tighten the chuck down enough. Each drill is clearly stamped on the hex portion. This is something that just couldn't be done on the smaller bits, without the hex shank. Drills through materials easily. Steel gives a nice clean cut, and the bit engages quickly. With Cobalt drill bits, it is best to go at a slower speed, and they will still cut just as effectively. It is very handy to have a range of sizes which go this small. For the quantity, and ease of operation, it's a good value set.
Review: Good set of 12 hex drive HSS Cobalt drill bits but no case to store. - This is a nice set of well made bits. Sold as Cobalt but only the 6.5mm one carries this on the shaft. All are marked with the sizes. They come loose in a box, just rattling about inside and coated with a film of thick oil. They are well attached to the 1/4" hex drive. This type can often create wobble but these are quite good, although not perfect. I do question whether the tiny sizes need this kind of mounting as they are easily prone to snapping. The tips are well ground and sharp so they should slice through steel etc with ease. Lengths vary with size and the maker has shown all of the physical sizes on the listing. Its a shame they dont come in a graduated plastic box. The box means you have to fumble about to find the right size. Good bits though and at £14.99 for 12 its good value.
