Saved my bacon twice already

Rounded off a caliper bolt on a Saturday and the Bolt Biter pulled it right out. The aggressive spiral bite grabs hard, even on fasteners I'd already mangled with vice grips. Every mechanic needs this set.

Works on the worst fasteners

Tried it on a rusted trailer lug that had been rounded off for years. First try with an impact and it came loose. The two drive adapters make it flexible on which tools you can use.

Good extraction set

Removes damaged bolts as advertised. They're thinner walled than normal sockets, so I wouldn't use them on healthy fasteners as a daily driver, but for extraction duty they work great.

Must have

Pulled a rounded axle nut that nothing else could touch. Buy it.

Works but limited sizes

Did the job on a stripped bolt, but the SAE sizing limits it on newer vehicles where metric dominates. Wish I'd noticed that before ordering. Quality itself is solid.

Fleet shop staple

We keep this set in the rollover cabinet for the inevitable rounded drain plugs and caliper bolts. Three techs using it weekly for a year and no cracked sockets yet. Far better than the cheap extractors that split on first use.

Solid value for a frustrating problem

Nothing is more annoying than a rounded bolt, and this set solves it cheaply. Used it with both a breaker bar and my impact gun through the adapters. Rung the sockets hard and they've held up.
