Really good drill bits
Item arrived quickly and adequately packed with other items.Having blunted two and broken one drill bit trying to get an exhaust bracket off my truck including one multi drill bit I sent for these drills and glad I did. No problem went through the stainless bracket first attempt, so very impressed. I also went through cast iron fencing bracket with no problems. So for me first class. The quality of these are first class compared to multidrill bits and seem pretty durable so value for money. Will gradually replace my multidrill bits with these especially for metals.

For the price, BEST by far.
I have been using this make (Rennie) of cobolt drills for awhile now & find they are very good.I trust the cobolt content stated, they stay sharp most of the time, even after the abuse i give them & they sharpen back up nicely.The best i can find for the price. Recommended. DO NOT buy chinesium.....

Some are useable
Used on hard plastic, 4mm thick, only used 3 of the 10, 1st snapped after lots of usage, 2nd wouldn't cut into the material only left a dent from pressure turned out to be flat, nothing snapped off, looking at the other bits no more were flat but the point angles varied massively, 3 were practically flat with the slightest of points, 3rd has lasted and remained sharp since, binned another that had a elongated spiral.In general quality control is inconsistent, you may end up up with more or less duds, cannot be certain how long each bit will remain sharp or how likely they will snap.If the rest do not snap before going blunt I would consider them worth the price.
