Keyohome10PCS Screw Extractor and Left Hand Cobalt Drill Bit Set, Damaged Screw Remover Drill Extractor Combination Set

I have an e-bike motor held in the bike frame by four T30 Torx steel bolts (M6x16mm). One had a chewed-up head and another had been snapped off at the bolt shoulder, leaving most of the broken bolt deep in the frame, so I knew I was in for some grief.I bought a set of these, despite the mixed reviews, as I thought they'd be worth a try. The main attraction for me was the drill bits are left-handed, so there's half a chance the drill bit alone will bite and remove a broken bolt if it's not too seized in. I had to use the smallest drill bit and smallest Easy Out bit for my bolt and despite the drill bit being quite fragile, I tried to take care not to snap it while drilling into the bolt.I used a pointed punch to make an indentation in the middle of the end of the broken bolt, switched the drill to anti-clockwise, added a little 3-in-1 oil to the drill bit and gently increased the speed and pressure allowing me to drill about 3-4mm into the bolt. I then tried the Easy-Out in a T-bar from a Tap & Die set and worked it in by hand, applying pressure inwards until it slowly bit into the bolt. Keeping the Easy-Out as straight as possible and keeping pressure applied to it as I turned it (anti-clockwise), much to my joy, the bolt slowly came out.Pics of the broken bolt in and then out of the frame attached.I don't know how effective these would be for bolts that are broken AND very seized, but the smallest drill bit and Easy Out worked in my case by removing my broken bolt, so I'm really chuffed ...and therefore I have to give them 5 stars!

The drill bits were good but one of them was broken when a opened up package apart from that really good

Did what it said in the tin,removed a snapped bolt from an engine block.

I was very disappointed with this product. The left handed drill bits a re cheap and low quality and basically go blunt almost immediately. This is a problem when you need to drill into a sheared bolt. The smallest drill bit broke almost immediately and the second broke off in the hole leaving me to try and drill that out too! But the biggest problem is the smallest easy out tool. The top of the tool is not squared off enough to get a small adjustable spanner or a dia handle on it so you can't rotate it once its been knocked into the hole! So really this kit is pointless and a waste of money! It made more of a mess than anything! I'd like my money back please!

Smallest snapped too easy but you get what you pay for

Does it’s job

I'm trying to remove a bolt that has sheared off in a clutch, it's well and truly stuck. I thought that this may help but it just doesn't bite into the bolt at all. I've used lots of wd40 for several days and have used a punch to shock the bolt and loosen it, the left handed drill bit doesn't make a mark on it and even after using a normal drill bit to drill into the bolt the remover just won't get any traction.

It actually worked. Used on a wheel bolt that had snapped. Really thought these would break. Felt like it was going to, so anything tough to remove, you may struggle with these.

Ha cumplido su cometido, aunque cuesta más de lo esperado. Necesité una llave fija para enroscar el extractor en el tornillo y la tuve que comprar.El precio me pareció un poco caro.

Aber was will man für 17,90 erwarten. Wer billig kauft kauft 2x.Absoluter Schrott die Bohrer. Bohren keinen Millimeter.Habe mir jetzt 2mm Bohrer von Bosch gekauft. Stück 2 Euro. Die Bohren wenigstens.Das Set gehört für mich in die Kategorie "Produkte die die Welt nicht braucht".

Que falta una broca y un extractor
