Bits will not cut

"I received this product as a Christmas gift. Prior to putting this on Santa's shopping list, I read the reviews and was preliminarily impressed. I had to extract a couple exhaust manifold bolts. I was excited to try these and thought they would make my job easy. I was severely wrong. The pilot bit might have drilled 1/4" deep in the stud till it dulled out. I used my Cobalt right handed bits that I got from Northern tool a couple years ago to pilot a hole and it cut through the stud like butter. I tried drilling it with a larger left hand bit (333113) after I pilotted the hole and it dulled out after drilling most of the way through the stud. I did not have good luck with this product. It cut worse than my right handed titaniums. Unless I got a bad batch, I would not recommend these to anyone."

First left-handed set I've owned

"I bought these to hopefully extract some broken shock absorber bolts on my Cherokee as I drilled them out. Didn't happen, but these cut through them like butter! I ended up re-tapping the holes they were so badly rusted in, but because these cut so well, it was quicker to drill them through than to mess around with an ez-out."

"The ultimate ez-out. In fact, the only one likely to work at all. We have all done it; snapped a bolt off in something valuable, where it must come out, with the least possible damage, these are the proper tool for the job."

left-hand drill bits

from S. Central PA
"I restore antique John Deere tractors and no matter what make of antique tractor you restore you come across bolts that either won't come out or break off. It seems like when I use the left-hand bits to drill the bolt for an easy-out that it helps to loosen the bolt to make it easier to get out.
I also have a good Drill Doctor with a left-hand adapter to sharpen my lef-hand bits. If you keep them sharp, they have no equal and give you a good job."

"These are good quality bits in a metal index box & left hand bits are the best way to remove broken bolts."
