Neiko 10-Piece Alloy Screw Extractor Solid Cobalt Left Hand Drill Bits Set

by Neiko

Product Description

The extractors are made of an exotic tungsten alloy and the bits are solid cobalt alloy. In use by the professionals! This set includes LEFT HANDED BITS. When you use left-hand bit to drill the hole in a broken screw or bolt so you can extract it, the odds are good that the very act of drilling will remove the broken screw without ever needing to use the extractor. Your drill must be running in reverse when you use left-hand bits. A broken bolt or screw may be removed from a hole with a Screw Extractor. First, drill a hole in the broken bolt. The correct drill size to use is marked on the metal case. Insert Screw Extractor in the hole and, with a Tap Wrench, turn counterclockwise. The Screw Extractor acts like a corkscrew. It grips into the sides of the drilled hole and removes the broken part on its own threads without damaging the threaded hole.

This review is from: Neiko 10-Piece Alloy Screw Extractor Solid Cobalt Left Hand Drill Bits Set (Misc.)

First time I tried the extractor, it busted off inside the bolt. Very hard metal, but so hard that it is quite brittle. Very little amount of free play, and doesn't let you put any torque on the bolt at all, so if it is rusted in there, forget about this set! Seems like a cheap knock off of the ever so popular "easy out" set.

Now I have to figure a way out how to get the stupid thing out of my bolt so I can drill a new hole and tap some new threads in. Can't drill it out because the metal is so hard, it is chewing up my drill bits.

I use these at my automotive school, notorious for un-calibrated torque wrenches and people who don't like reading directions. I would go with professional grade set if your working on rusted bolts, or in awkward or tight situations. Otherwise, for light to medium duty work: Buy 2 of these sets to save on shipping. You will need the extra set. The slightest vibration can snap the bits, they are very brittle. Consider your first set a 'learning set'. If you use them to remove another bit that has broken off in a broken screw, they grind into dust (Doh!). These work great on bolts which have been over torqued or snapped on re-install.

I ordered these with high hopes that they would do the job for me but it turned out not to be the case. The left hand drill bits did not seem very sharp at all and were not able to make any progress on the bolt which was stuck. The screw extractors were not close to the same level of quality of a standard Black and Decker one which could be bought at Home Depot.
