COMOWARE Left Hand Drill Bit Set, 13 Piece High Speed Steel With Titanium Coating -Size (1/16" - 1/4")

Despite using cutting oil and taking my time I still broke the 1/4 bit. The other bits dulled quickly. May be ok on an aluminum bolt or screw but not steel. I would go with the hog bits if I had to do it again. My Dad always told me you get what you pay for.

Decent quality at a fair price. Working well so far and seems like the bits willaverage lifespan if treated right.

Nice solid quality! Folding case makes it easy to access when opening.

they worked reasonable well for the price, but the first one I used ( I think it was the 1/8") broke immediately. their sharpness wasn't the best, none the less it did the job.

Thankfully, I haven't needed to used them yet, but these bits look good and come in a nice case. They should be great for removing broken bolts. Now I just need to go find some rusty equipment to repair...

Used just one of the sizes so far but it didnt break and did what it was suppose to

Barely made a dent in a stainless steel screw and this was with drill oil being used. Later one bit snapped in half.

I like it, used it for inhouse repairs, to decorate (shelf woodwork), affixing shelves & towel racks to walls.
