The collection includes all the fundamental bit widths needed to operate effectively in any project. It is appropriate not just for metal but also for many other materials, such as wood, plastic, and glass.
All components are made of high-speed steels, which provides them exceptional strength and endurance. You will certainly be able to use the set for a long time. They give you a plastic box to arrange all your components and parts.
Thanks to the box, locating and storing the right part will never be a problem again. The most beneficial characteristic is the titanium coating that prevents corrosion and increases durability of this drill bit. When you work, you will not experience considerable heat growth, as you would with other products.
It is also worn and tear-resistant. The Hurricane Titanium set will give you the best long-life possible, and it will also help reduce heat build-up. On top of all of its features, it also ensures strength and durability to its maximum extent. It also comes with easy storage and transportation ability. The only con about this product is probably its price point being a bit too high than anticipated. It includes a comprehensive handbook with much-needed suggestions for a straightforward procedure.
Beginning with traditional metal RPM charts, these tutorial handbooks will teach you all you need to know. Additionally, fast-cut degrees eliminates the requirement for a center punch. The parts insert easily with little pressure. Although Hmynorg is relatively unknown, it achieves an exceptional price-quality ratio. With a spiral flute and straight shank construction, the Hymnorq Metric M35 is ideal for iron cutting.
These bits of Cobalt alloy are robust enough to endure some abuse. The metric design ensures that the sizes are correct for any application. The advantage of these components is that they may be utilized in both light and heavy-duty applications. Metric bits are much more durable and resistant to heat than standard HSS bits. The set includes 13 bits ranging in size from 1,5 to 6,5 mm. Hymnorq is not required to locate a punch center to shift the bit. Throughout the operation, the tip is centered and angled at degrees.
It will not slide over the surface due to the tilt, which aids in penetration with little pressure. However, pieces may be ineffective against high carbon, strong steel. Because these bits are also very hard, they are more fragile than HSS bits. You may utilise coolants to extend the life of the bit during operation.
There are a few durability issues with the drill bits as well. They are particularly well suited for usage on abrasive materials such as stainless steel, cast iron, and high-density metals. They are capable of drilling everyday materials such as wood, plastic, and light metals. Indeed, the firm is certain that its cobalt metal drill bits would outlast conventional drill bits by a factor of four. When one thinks about Bosch, one immediately thinks of German engineering and efficiency.
This piece drill bit set has diameters ranging from 0. Bosch manufactured exceptional cobalt drill bits for the convenience of its users. This set is suitable for contractors and experts since it was built without a skating start and a split-point tip. With a good start, you create precise holes. Additionally, they are capable of working with lighter materials such as wood, plastic, and light metals, making them an excellent all-rounder. To minimize movement and deflection, you must have the metal securely fastened to the working table.
If the drill speed is set too high, it will produce an excessive amount of heat. The drill will also fail as a result of this failure mode. Identifying the most appropriate feed control will be essential, especially when it comes to breaking the chip. A drill bit is what makes the hole or cuts in your work. When stainless steel work hardens, it becomes very hard and extremely difficult to drill. Start with a sharp drill and have it turning as slowly as your drill or drill press will allow.
I set my drill press to its slowest speed or run my portable drill as slow as the trigger will allow. You need to exert a lot of pressure on the drill bit—as much as it will bear. You will know if you are exerting enough pressure if a continuous spiral of material comes off the bit as it turns. The photo above shows the kind of stainless spiral you should see as you drill. You must keep the drill bit and stainless material cool. Machine shops have a continuous stream of lubricant that they spray onto the tip of the drill bit to both cool the drill bit and the stainless and to lubricate the cut.
However, what you can do is regularly stop drilling and drip some oil onto the bit and in the hole. If you have a helper, you can also have them place a few drops on the bit as you are drilling to speed up the process.
Ideally, you want to use cutting oil, although motor oil or even WD will do the trick. I even used olive oil once. The key is to stop often for cooling and to make sure there is plenty of oil. If you follow these suggestions you can quickly drill stainless using a standard highspeed steel bit that you can buy in any hardware store. But Be Careful! While this procedure will allow you to drill stainless, you need to take some precautions.
Everyone involved in or watching the drilling must wear safety glasses. If you click on the images of the twist drills in the PDF, you will be taken directly to the product page where you can find detailed information about the twist drill.
Since stainless steel is a very hard material, you have to choose the right twist drill. Over time, however, mixed forms have been developed whose naming systems are not standardized in the DIN manual.
When drilling, you should follow these advices: cooling adjust speed use twist drills that hasn't already been used for other steels clamp workpiece do not wear protective gloves put on protective goggles. If you have found the right twist drill and follow these instructions, you will get a good drilling result in stainless steel.
In each of our product groups you will find a Product finder. You will then be shown all twist drills that can be used for cutting stainless steel.

In general, the more cobalt, the harder and therefore more brittle the drill. Due to the fracture susceptibility of hard tool steels, you should better use HSS drills for soft materials.
DIN division of application groups. Under certain conditions e. These carbide-infused drill bits are one strong option when drilling into stainless steel.
Infusing drill bits with cobalt is another way that manufacturers achieve ultrahard drill bits. High-speed steel, also known as HSS, is the most common drill bit for metal applications. Cobalt bits are an extension of HSS bits.
They incorporate an element with between 5 percent and 8 percent cobalt that makes the drill bit harder than a typical HSS bit and thus suitable for precision drilling in stainless steel and other hard materials.
Many manufacturers complement construction materials like drill bits with metal coatings. These coatings promote penetration and protection of the drill bit.
Black oxide coatings reduce friction and heat—a significant consideration when drilling metals. Black oxide also protects against corrosion and water, keeping the drill bits functional for a longer period of time. Titanium Nitride TiN protects high-speed drill bits. Distinctive for their golden color, TiN-coated drill bits are ideal for high-speed drills.
The coating provides the ancillary benefit of being ultradurable, making them an excellent value for consumers who intend high-frequency use. Titanium Carbonitride TiCN is likely the most durable metal coating available. TiCN bits are blue-gray in color. Their coating makes them incredibly resistant to wear and capable of enduring high-speed and high-frequency use.
Because of its hardness, stainless steel is an unforgiving construction medium. Usually, there is only one chance to achieve the perfect drill hole.
Another crucial consideration when purchasing drill bits for stainless steel is the drill bit number or size. Drill bit numbers are related to wire gauge size. The larger the bit number, the smaller the diameter of the resulting hole. For example, a number 80 drill bit creates a hole with a diameter of 0.
As the diameter grows larger, the bit number grows smaller.
