Large bolt cutters, which can be as long as 48 inches, can handle hardened steel rods, heavy chains, and thick threaded cable up to 7/16 of an inch in diameter.
Bolt cutters are the common tool of choice for to cut padlocks during forcible-entry. Unfortunately, most padlocks are made of case-hardened steel, which is very strong in comparison to the materials that bolt cutters were intended to cut.
If a clean cut is desired when cutting through hardened steel, or if the steel's hardness must be retained, a fine toothed hacksaw will work wonderfully, though the process is long and will require a great deal of intense effort.
Steel alloys tend to give the strongest protection against bolt cutters. Boron alloy is one example of a material that's difficult to cut through. Hardened steel is also used in many locks and can make the lock more resistant to bolt cutters.
Large bolt cutters that measure 30 to 42-inches are perfect for cutting through medium-hard metal materials like thick steel chains, copper cable, steel rods, and large bolts and padlocks.
The hydraulic bolt cutters use a motor to power the cutting blade. A hydraulically operated piston propels the cutting edge with significantly greater force than a handle-operated bolt cutter. Because of this added power, hydraulic bolt cutters can cut soft metals approximately one inch in diameter.
Cheap Chain Cuts Easily
A $20 bolt cutter cuts easily through chains, cables and padlocks up to 3/8 in. thick.
ABUS Granit™: one of the world's most secure padlocks with a tensile resistance of over six tonnes. Granit locks have a tensile resistance of over six tonnes, making it almost impossible for attackers to release the shackle from the lock body by force.
It's not a criminal offence to carry bolt cutters, and without witness evidence of you actually stealing a bike there is nothing the police could do even if you were a known bike thief with a long history.
Hardened steel is a very useful material, but working with it is tough because it is nearly impossible to cut with simple tools. What you really need is an angle grinder, and this video will show you how to use one of the powerful power tools to cut a hardened steel ring.
Diamond Grit blades also cut hardened steel, however they are expensive and take longer to cut through the material.
Hold the grips on your cutters and apply firm pressure to break through the lock. Squeeze the handles together until it cuts through the shackle. If you can't cut through the lock yourself, ask a friend to help you close the bolt cutters. If the lock is made of hardened steel, bolt cutters may not work.
Bolt Cutters
The person who is handcuffed cannot use this tool on themselves, but the bolt cutter can safely be used to remove the wrist cuffs.
Turns out, any Master Lock can easily be broken into with just a small hammer. As this video illustrates, all you need to do is tap the side of a Master Lock with a hammer to get it to open, no key, no combination required.

It is one of the toughest padlock to cut or drill since it is resistant to all of that along with its hardened boron steel shackle. It is also shrouded with a hardened steel body. It is one of the biggest padlocks in the world as well as one of Abloy's largest.
Unpickable Locks Do Not Exist.
Tungsten carbide rings are made of the hardest metal on earth. This is what gives it its scratch resistance, but this durability also means these rings resist cutting tools. Because these rings are so strong, many people worry about whether or not they can be cut off in case of emergencies like finger swelling.
Pure gold is virtually indestructible. It will not corrode, rust or tarnish, and fire cannot destroy it. This is why all of the gold extracted from the earth is still melted, re-melted and used over and over again.
Researchers claim the material, known as Proteus, cannot be cut. In fact, it's so tough it destroys any tool that attempts to slice into it. Natural materials like diamond and sapphire are strong because of the dense lattice of atomic bonds, but they're inflexible.
Size does matter when it comes to bolt cutters. The longer the arms, the more leverage created and therefore, more cutting power. 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.
Can Kryptonite Bike Locks Be Cut? Unfortunately there isn't a lock out there that can't be cut. That being said, the Kryptonite Fahgettaboudit Mini's 18mm hardened steel shackle is impossible to crop by hand with bolt cutters.
Tolsen industrial 14 inch bolt cutter is ideal tool for cutting rods, rivets, locks and chains.
