Felix Ure, a product design undergraduate, had his mountain bike stolen as a boy and has now created the Hench lock – a security device that uses high-strength fibre material Kevlar. Felix, originally from Tunbridge Wells in Kent, said: “I know how it feels to have a bike stolen It’s really important that a bike lock can last long enough for a thief to be deterred. I wanted to design something which could help people avoid having to go through what I did.” A video shows the 23-year-old trying to destroy his bike lock with angle grinders, bolt cutters and more.
The problem with most materials that can’t be cut relatively easily with an angle grinder and the proper disk/blade is that it is going to be a) very expensive, b) very brittle and hard to work with, and/or c) extremely heavy. As mentioned by James, something like a high carbon, high molybdenum steel, such as VG-1 or ATS-34, hardened to a Rockwell B-scale of >60 would be hard to cut with an angle grinder. Making a practical cable or chain that can’t be cut with a diamond wheel on an angle grinder is a tall order.
That’s what makes the marketing claim behind the pre-release Altor SAF Lock so compelling: It’s the world’s first angle grinder-proof bike lock. At 13.7 pounds, it’s twice the weight of a Kryptonite New York Fahgettaboudit Mini U-Lock and about as heavy as a 5-foot Kryptonite New York chain lock, so don’t think of the SAF Lock as a regular bike lock. Akers told Bicycling that Altor set out to make a lock that could withstand 45 minutes of angle grinder cutting, so in that regard, the SAF Lock succeeds.
I’m wanting to beef up my door with a heavy duty security gate but I’ve seen how fast an angle grinder can cut through a lock. I was thinking of adding some housing on the very outside of the hasp/lock/hinges/face that I could fill with something to foul up a grinder wheel. I thought maybe putting in a bundle of 900 lb Kevlar strands that would get pulled into the wheel similar to chainsaw chaps.
In a successful attempt, engineers have manufactured a material that is now being hailed as the world’s first metal which cannot be cut. The material, named Proteus, cannot be cut using either angle grinders, drills, or high-pressure water jets. While an angle grinder or drill might cut through the outer layer of a Proteus plate, it will not be able to go through or harm the embedded ceramic spheres, which uses destructive vibrations to blunt any cutting tools.
If you’re looking for an unbreakable bike lock, then unfortunately I’ve got some bad news: no bike lock is unbreakable! It’s also worth noting that the strongest bike lock doesn’t necessarily mean the best bike lock for you…. As we’ll see: with great strength comes some compromise! The more secure a bike lock is, the heavier and less practical it is. If you ride a desirable, high value bike in a high risk area then you need a super secure bike lock and these are the best you can buy.
Engineers from Durham University and the Fraunhofer Institute have created the first synthetic material that can block even the most determined intruders. Researchers claim the material, known as Proteus, cannot be cut. With the right tools, you can cut and fracture a diamond.
kevlar vs angle grinder Related Question:
Is there anything an angle grinder can’t cut?
The inspiration behind this creation is the natural defense mechanisms used by shells, grapefruit skins, and fish scales that makes them resistant from the attacks of various sea creatures. The material, named Proteus, cannot be cut using either angle grinders, drills, or high-pressure water jets.
What material stops an angle grinder?
Instead, this Ferosafe stuff is a graphene composite material specifically designed to resist angle grinders and drills, and it’s made by a British materials manufacturer called Tenmat who have partnered up with Hiplok. Essentially this stuff disintegrates angle grinder blades!
What is the most difficult material to cut?
Diamonds are largely considered to be one of the hardest, naturally occurring materials on Earth, although with the right tools, you could actually cut or fracture a diamond.
What is the hardest chain to cut?
By being the toughest chain, we mean the Pewag chain is the hardest chain to cut with bolt cutters. The biggest reason is the hardened steel chain is squared, so it will not allow bolt cutters to cut through it.
What do bike thieves use to cut locks?
Wire/cable cutters A pair of hand held cable cutters will snip through most cable locks in seconds. Cheap, inconspicuous and easy to carry around in a coat pocket, this is the tool that’s most commonly used by bike thieves. And it’s worth repeating again: they will cut through nearly all cable locks in seconds.
Can an angle grinder cut hardened steel?
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.
What material Cannot be cut?
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.
What metal Cannot be cut?
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.
Can a grinder cut through a lock?
If you happen to have an angle grinder, you can easily cut through a padlock without needing a bolt cutter. You will need a metal cutoff wheel with your angle grinder as well, but these are not terribly expensive. Before you start cutting away, though, you will need to wear the proper safety gear.
Can a grinder cut through titanium?
✽[Product Usage]: It can be used with angle grinders and cutting machines, suitable for cutting titanium plates, color steel plates, stainless steel and various metals. You must wear protective glasses, dust masks, and gloves during installation.
How do I protect my bike with an angle grinder?
Hiplok reveals ‘world’s first truly portable bike lock to resist angle-grinder attacks’ British security and storage brand Hiplok has launched a 1.8kg portable bike lock solution that it claims is capable of resisting “a severe, sustained angle grinder attack”.
What type of chain Cannot be cut?
Hexagonal links (or square or trapezoidal) make it impossible for bolt cutters to get a grip. Chain sold by the foot at the local hardware store performs lifting and towing well, but not theft resistance.
Is there a cable that can’t be cut?
Is there a chain that can’t be cut with bolt cutters? The short answer is yes, you can get cut-resistant chain. It’s hardened throughout its thickness, and its flat face distributes the force of the bolt cutter’s jaw over a wide area, thereby diffusing it.
Are there any bike locks that Cannot be cut?
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.
Can you grind AR500?
Experience is key when it comes to grinding and machining companies partnering with steel mills. Materials such as AR400 and AR500 can be tricky to work with, and many grinding and machining shops do not have the expertise or equipment to work with these rigid materials.
