High quality bolt cutters with a powerful ratchet hinge (where locking gear rotates and holds the blades tighter every time you squeeze the handles) are used in a similar way to conventional bolt cutters, with just a few differences.
Step 1 – Assess material
As with all bolt cutters, it is important not to attempt to cut material which is too tough for the blades. Check, before you start, that the metal or other substance you are cutting is not too hard for your tool.
Step 2 – Release handles
There is sometimes a button at the jaw end of the tool which you press to release the handles. Open them wide to spread the jaws.
Step 3 – Enclose material
Position the jaws of the bolt cutter so that the material is as far down the blades towards the neck as possible (where the cutting force is strongest). Close the jaws to grip the material firmly and stop it slipping out.
Step 4 – Brace one handle
Steady one handle (the side without the ratchet lock) against your leg, on the ground, or on another convenient surface.
Step 5 – Apply force to ratchet handle
Slowly and firmly press the non-braced handle of the tool towards the other one.
Step 6 – Repeat
Once you have exerted the maximum force you can with the initial cut, pull the ratchet handle away from the other one – spreading the two as far apart as possible – then bring them together again. Repeat this movement – each time tightening the jaws a little further – until the material is cut through
Step 7 – Remove bolt cutter
Once you have achieved a full cut, move the bolt cutters away from the material. If there is a release button, press it, and then pump the handles of the tool until the jaws reopen completely.
