In both types of can, ends are sealed using a double seam. This process, crucial to the integrity of the can, attaches the can end or lid to the body by mechanical process. Three layers of the lid and two of the body are interlocked to create a seam. Done properly, it creates a hermetic seal to keep the contents fresh.  Find out more about the process in our handy double seam guide.

How are cans made step by step

Titanium nitride (TiN) is a very strong ceramic substance that protects the steel bit and allows it to last longer, especially when drilling hardened steel.

Therefore, cobalt drill bits have a longer life and are more heat resistant than titanium drill bits. Which means cobalt drill bits are typically better since they are much more durable than titanium-coated bits and can drill holes through the hardest metals.

In computing for the RPM, for example 1"-diameter tool must run at 30 sfm. Based on the equation above, at 30  sfm: (30 × 3.82) ÷ 1 = 114.6, this means you have to use 115 RPM to drill a 1 inch Rockwell C 40 to 45 steel.

Titanium drill bits are high-speed steel bits with a titanium nitride (TiN) coating, whereas cobalt drill bits do not have a coating; the entire bit is constructed of alloy steel that contains 5 to 8% cobalt.

Measure and mark the hole, then use a center punch and hammer to make a slight indentation. Drill bits tend to wander when they first start drilling. Therefore the dimple helps the drill bit become more steady. The dimple also serves as a reference for where to drill your hole.

A 2 piece can is made of two main parts: the body and one end. The body is made from a disc, typically aluminium, and reformed into a cylinder with an integral end. Another end, or lid, is then attached with a double seam, closing the can.

If you are short on time, the best drill bits for hardened steel are carbide-tipped bits. They are the most suitable drill bits for hardened steel due to their robust and heat-resistant properties. However, there are other options such as titanium and cobalt.

Lubricant should be applied to both the drill bit and the drilling surface. To reduce the temperature, repeat this step between drillings.

For better protection, use safety glasses that wrap around the sides of your face. Eye protection is required to ensure that a tiny metal fragment does not cause significant eye injury.

Cobalt has a high melting point of 1495°C, making it ideal for high heat drilling applications like hardened steel. The most common are M35, a 5% alloy, and M42, a 7% alloy.

Carbide drill bits are typically harder than cobalt drill bits, although both are suitable for drilling stainless steel and other hard metals. However, Carbide drill bits retain their sharpness for a longer period than cobalt drill bits. They can also be utilized at a faster cutting rate and withstand higher temperatures than cobalt drill bits.

Roughly three quarters of the world’s beverage cans are made from aluminum. Not only is it cheap and efficient, it’s also infinitely recyclable. The remaining quarter are made from tin-coated steel, which is also the most popular choice for food cans. So, what are food and beverage cans made from?

Carbide drill bits are used for drilling broken bolts, safes, studs, bearing races, taps, and knives made from hardened steel. They are designed to allow the quick dissipation of heat and prevent chipping.

When comparing the carbide, both cobalt and titanium drill bits are better than regular steel drill bits due to their added components, as well as their resistance to heat and wear. However, in terms of hardness and longevity, the carbide drill bit is better than both of them.

Cobalt drill bits are not made of pure cobalt. Instead, they are made of steel combined with a small proportion of cobalt, often between 5 and 7 percent, and the remaining part steel.

Titanium drill bits are high-speed steel bits with a titanium nitride covering. Titanium-coated drill bits provide many advantages over ordinary steel bits, including the ability to endure greater temperatures, increased wear resistance, and higher durability.

Hardened steel types include ATS34, CPM440V, Z60CDV14,  Sandvic, and 12C27. Carbon steel must go through a succession of heat treatments, quenching, and reheating to become hardened steel.

Make sure the piece of metal is in a flat and secure area. Holding the metal with one hand while running the drill with the other is not a good idea. It is better to secure the metal with a clamp.

When drilling through hardened steel, you must ensure that your drill bit is made from tougher materials. Carbide bits are the strongest drill bits material and can cut through hardened steel. But if they are not available, titanium and cobalt drill bits can also be used. However, drilling with either of these bits will take longer than drilling with a carbide drill bit.

Rockwell hardness testing is a standard method for determining the  hardness of metals and polymers. Rockwell hardness is measured with a device known as a Rockwell hardness tester. The tougher the steel is, the higher the number on the RC scale. The higher the RC number, the slower the drill speed should be.

If you've worked with hardened steel before, you'll know that a regular drill bit won't cut through. Your best bet is to use the carbide bits because they are the hardest drill bits available.

There are many other things to consider when choosing the right drill bit for hardened steel. This post will cover what you need to know about drilling hardened steel and provide you with some suggestions on the best drill bits that will work well for your needs.

A crucial stage in the production of beverage cans is the testing and QA. Even fractional discrepancies can compromise a can’s integrity, causing leakage, venting or degradation of the content. For some insight into the way the beverage packaging industry is currently behaving and adapting, check out our Thirst for Perfection report.

A 3 piece can has three main components: a body and two ends. For a body, a flat panel is mechanically formed into a cylinder and welded. The body may then be beaded or necked for ease of stacking or display. It is also often coated with a lacquer, depending on the materials used and eventual purpose. The ends are attached by a seaming process, typically a double seam.

There are two main methods for making beverage cans – the 2 piece can and the 3 piece can – and the manufacturing processes differs for each. 2 piece cans by far dominate the beverage industry, but 3 piece cans are still in use in some parts of the world, particularly for non-carbonated beverages.

The aluminum used in beverage cans is alloyed with manganese and magnesium to improve strength and ductility (its ability to deform rather than fracture under pressure). Different alloys and aluminum thicknesses are used for different components of a can.

Aluminum measurements and alloys can be tweaked for maximum efficiency, but must always be carefully QA tested to ensure that they are of a sufficient strength and thickness to avoid warping or implosion. This is an integral part of any can inspection process.

If you are in the process of drilling hardened steel, maybe for one of the reasons mentioned above, or potentially something completely different, why not take a look at the drill bits we have available for metal. Our range is designed for high end performance and is suitable for those drilling hardened and normal stainless steel.

Carbide drill bits are the toughest drill bits available and best for drilling hardened steel. Carbide is a  compound made from tungsten and carbon. Carbide drill bits are typically composed of steel that has a carbide tip.

Hardened steel is used in energy,  transportation, general mechanical engineering components, and many other applications. Axles, arbors, driving pinions, camshafts, and Cardan joints are examples of hardened steel components.

The average beverage can has to do a lot of heavy lifting. It is expected to be light, incredibly well-sealed, and designed to help the contents reach the optimal temperature quickly.

The drill speed is critical for drilling hardened steel. Drilling at high speeds causes high temperatures, which will damage your drill bit. Therefore, drilling hardened steel should be done at a low RPM and feed rate. Feed rates are typically at least 50% lower than for lesser hardness steel. Speeds generally are 30% of that of a non-hardened material.

However, it would be best to exercise caution when using carbide-tipped drills since they can be brittle despite being the hardest. Because of their great strength, they are extensively employed in industrial applications. They can cut through concrete, masonry, tile, and hardened steel.
