Description of π§ Irwin Industrial Tools 11117 Extractors: Powerful Solutions for Removing Stubborn Screws and Bolts
Designed to remove broken studs, bolts, socket screws and fittings. Aggressive left hand spiral design for extra gripping power. Spiral flutes are designed to embed themselves deeper into the metal as you turn the tool, so as the fastener resistance increases, the extractor's grip increases. Extractor size and recommended drill bit size are etched on each tool. Set includes plastic pouch.
I had to find a broken antenna tip on the roof of a 2012 Jeep Liberty. Before receiving this kit, I sprayed the hole with WD40 gel. Received this kit, slowly drilled with a drill from 2nd to smallest then arr. a piece. The woman recorded 42 seconds. He took it out and screwed in a new antenna. AMAZING tool.
Pros
Extractor size and recommended drill bit size are engraved on each tool.
Bits are not guides to cut into a broken screw cap. I could never get them to drill a pilot hole to make the extractor work. (Maybe others = why two stars) The bits are right handed and the extractors are left handed as they should be but the tips need to be blunt to get started. It's disappointing that they don't work well, but I haven't found any extractors that work yet. And as stated in another review, = delivered in plastic.
I removed a hardened bolt on my mountain bike. I found out that the screw extractor is a screw extractor, so I went with a cheap Chinese manufacturer of an unknown brand. Big mistake. After 45 minutes I was left with a useless tool and a big disappointment. After doing a little research I came across this MFG kit from Irwin which I know from previous purchases make quality tools. Well it only took 2 minutes to get my stripped stud out. Some thoughts. The exercises were fantastic. No problemβ¦
