This original KUKKO design has proven itself in decades of rough & tumble service all over the world.
Advantage: constantly parallel claws in any position, so that only the contact faces actually touch the part to be pulled. Sturdy construction, high performance, handy shape, form-cut feet for use in confined spaces. Universally applicable, with interchangeable claws for any required depth. For outside and inside pulling.
For removing bearings, gears, discs, etc. in tight or difficult to access spaces.
