StudPuller

Select a Method:

Safety:

    Safer; Reduces Risk of Injury

    Operator injury could occur when over tightening or shearing a stud.

    Possible burn or ignition of other materials

    Flying debris & metal shavings

    Back injuries

    Low risk if set up properly

Science:

The StudPuller uses two opposing jaws on internal cams to grip and squeeze studs to
create rotation of the stud.

Binding two nuts against each other creates a mechanical bind, which stretches the threads

Damages stud and possibly the housing

Drilling a stud is a slow, heat-building process that grinds away metal with risk of slipping off-center and damaging threads.

Side loading occurs when “pulling” on a stud. This creates a mechanical bind in the threads

An alternative to drilling, MD uses an electric arc to break down the metal and burn through the center until the stud collapses. this method usually guarantees the protection of the housing over drilling. The cutting action of a metal disintegrator is accomplished by creating a series of intermittent electric arcs that break down the hardest metals into minute particles.

Common Issues:

Rotation is the fastest, safest and least expensive way to remove studs. issues are lack of training, burning jaws, under powered equipment, lack of proper air supply.

Nuts just rotate and don’t lock against each other, nuts won’t release after extraction, stretches threads, uses lots of time

Having a welder on hand, nut doesn’t weld on center, weld breaks, stud destroyed

Inordinate amount of time, getting drill into tight spaces, set up time just to get started, possible damage to housings

Safety issues: pulling on a breaker bar is extremely dangerous and bad for the back, heavy side loading, damaging the housings and threads, bending studs or shearing studs

Set up time is high, arc time is based on diameter of stud and constant monitoring, machines are large and don’t fit in tight spaces, machines are expensive and usually come with an operator

Productivity:
