A hacksaw might work with a lesser quality lock, but you’re going to be cursing at the moon if you try one on hardened steel. Ideally you’d use an angle grinder (is the bike near a power source?), but a Sawzall with a metal-specific blade would work fine too (wrought iron workers use the latter.)
Carbide tipped blades cut harder, denser metals like hardened steel , cast iron, alloys including boron steel, and higher grades of stainless steel. These blades are extremely hard, heat-resistant, and impact-resistant. They are typically 8 TPI.
Cut through the U-lock with the angle grinder .
Hold the blade against the side of the U-lock until it cuts through. This can take anywhere from 15 seconds to a few minutes. Be very slow and deliberate when you use the angle grinder.
Shortening the chain
In order to shorten the link without a chain tool, you need an alternative tool like a hammer, pliers or thin nail . They will assist you in pushing the pin easily. You can position the chain over a socket, and hit it with a hammer. Then, you can now pass the bolt all throughout the open holes.
Use bolt cutters to snip through the links if you want to remove, replace, or shorten a section of the chain link. Use a reciprocating saw to cut the posts or rails if you want to shorten, remove, or replace them.
Without cutting the chain
There are other solutions: Make several turns around your wrist to have a multirang bracelet or around your neck to make a build-up of choker . If your chain is not too big, slip a pendant over your chain and tie a knot just above. Place your clasp on another link, somewhere else on the chain.
Size and Weight
An 18-inch bolt cutter can cut metal up to 9/32 of an inch in diameter while a 24-inch bolt cutter can cut thicknesses up to 5/16 of an inch, depending on the material’s hardness.
In general, the best sawzall blades for cutting metal have a higher TPI (Teeth Per Inch) and are bi-metal or carbide tipped . The right TPI and blade material depend on the type of metal being cut and its thickness. Cutting thinner metals, including sheet metal, requires a finer cut. Use 18-24 TPI bi-metal blades.
The Reciprocating Saw
A reciprocating saw is another option. As with a hacksaw, you will need a suitable blade for cutting rebar – one with fine, sharp teeth.
They will use the hammer to repeatedly strike your bike lock until it breaks open . Low-end cable locks and cheap d locks can be defeated this way and will be the target for thieves using a hammer.
While Kryptonite don’t guarantee it can’t be bolt cropped , it would take a very skilled (not to mention big and heavy) thief to get through this chain.
Is There a Bike Lock That Can’t Be Cut? The Altor SAF and the Skunklock are the two most uncuttable bike locks on the market . Both of these locks employ anti-cut features that make them capable of defeating power tools. These two locks are the strongest and most unbreakable bike locks on the market.
