33 Pcs Spiral Screw Extractor Bolt Extractor Set, 6542/4341 HSS Left Handed Drill Bit Set, Easy Out Bolt Extractor Set for Removing Broken Stripped Screws Nuts with Solid Storage Case

Fantastic, drill bit worked well and extractor got the screw out. Was struggling with a stripped rotor screw on my car and this thing helped get it out like it was nothing.

I broke the knock sensors in an ls1 and sure enough small holed them a bigger hole and nice an easy, the broken sensors cam out.

Extractor broke in the hole, drill bit won't go thru it. I'm not stuck worse than before I tried this.

Great addition to my tool bag. Aircraft mechanic here, and I bought this when I noticed I had lost my #2 extractor and broke my reverse drill bits(#1 & #2) from my snap on kit(180$ snap on set with just the bare minimum, bits and extractors). I ordered this mid day Monday and it arrived Tuesday morning before going to work and put them straight to use. Drilled out T20 screws full of paint so you can imagine every screw would strip when trying to remove. Used reverse drill 5/32 bit incorrectly and made it wobbly. Comes with a SECOND BIT WITH THE EXTRACTOR! Used it correctly(finding right pressure and speed on drill for efficient cut). I was drilling through screws like butter and the extractor shortys were the muscle to walk these screws off. Drilled about 60 screws in 8 hr work day(physically weak after/low energy obviously) but had it not been for overnight shipping and well quality set, getting these panels removed would not have been possible. Worth every dollar, not gonna be disappointed with your purchase would recommend to any aircraft mechanic trying to build their tool box.

The drills are not good. They would not drill a grade 8 bolt. Had to use my normal drill set, no problems. Have not tested the extractors yet. Hopefully they do not brake or twist. I now see the problem, these are "Left Hand" drill bits. I need to turn the drill in the opposite direction. Wow, I never thought of that. Ok the drills work good when you change the direction of the drill. Now I just need to find a Left Hand drill bit sharpener.
