Coating technology is one of the advantages of RDF International. At present, RDF International partner has a professional milling coating company, Pilate coating equipment and coating technology from Switzerland. Is coating tool (RDF International) better than non-coated tool? In fact, it is not necessary. We need to use tools with different characteristics in the corresponding situation to maximize the efficiency of the tool. Below we simply analyze the advantages and disadvantages of the coated tool:

Firstly. Advantages of coated tools
Tungsten carbide milling cutter-coated tool has attracted much attention due to its excellent cutting performance. It has high surface hardness, good wear resistance, low friction coefficient and low thermal conductivity. The coating material acts as a chemical and the thermal barrier reduces the diffusion and chemical reaction between the tool and the workpiece, thus reducing the crater wear.
Compared with uncoated tools, coated tools can increase tool life by more than 3 to 5 times, improve machining accuracy by 0.5 to 1 and reduce tool consumption by 20% to 50%. The durability of coated carbide tools can be increased by 2 to 10 times. If the durability is maintained, the cutting speed can be increased by 25% to 70%. The durability of coated HSS tools can be increased by 2 to 5 times or even 10 times. Since the advent of coated tools, not only has tool coating technology been rapidly developed, but also a wider variety of coatings. The coating tools used in industrialized countries account for an increasing proportion of cutting tools, about 70% to 80%. Coating tools have become the symbol of modern tools.
Second, the disadvantages of coated tools
Although coated tools have many advantages and are used more and more, they cannot completely replace ordinary uncoated tools:
(1) Because the toughness of the cemented carbide tool is reduced after coating, the coating tool is not suitable for rough machining under heavy load and big feed intermittent cutting.
(2) In order to increase the edge strength of the coated tool, the tool before the coating should be polished, the radius of the edge radius is generally 10~80um, and the cutting edge strength increases with the increase of the radius, so it cannot catch up with the uncoated tool, the uncoated edge is sharper. The blunt radius Rn of the cutting edge of the cemented carbide tool coated by the CVD is generally 0.02 to 0.07 mm, and the radius Rn of the cemented carbide tool coated by the PVD is smaller, but generally not less than 0.01 mm. This makes the coated tool unsuitable for small feeds, such as 0.015mm finishing, not suitable for minor finishing.
(3) When the coated tool is cut at low speed, it is prone to peeling and chipping, so it is not suitable for low-speed cutting situation.
(4) Coating tools are not recommended for the processing of high temperature alloys (such as nickel-based, cobalt-based, iron-based alloys), heat-resistant steels and titanium alloys, non-metallic materials (such as graphite, fiberglass, nylon and Plastic), non-ferrous metals and alloys (such as easy-cut brass, bronze, nickel, silver, pure copper, manganese, zinc and other alloys) and difficult to process colored alloys (such as aluminum bronze alloy, silicon aluminum alloy, manganese bronze alloy, Monel alloy and nickel-copper alloy).
(5) Coating tools are also not suitable for processing high hardness materials, such as steel materials above 300HIB, chilled cast iron and hard inclusion materials.
(6) Deep hole drilling, cutting, threading and cutting of chips are difficult to discharge, the effect of using coated tools is not very good, either it is not suitable for processing the surface with sand and hard skin.
Third, Application of coated tools
Coated tools can be used to machine workpieces of different materials, for high-speed finishing, general finishing and light duty to heavy duty of various carbon structural steels, alloy structural steels, easy-cut steels, tool steels, alloy cast irons and nickel-chromium stainless steels. For roughing of loads, coated tools are preferred; for high-speed finishing of cast iron and nickel-chromium stainless steel, general finishing and light-load roughing, coated tools are also preferred. Therefore, the steel processing rate of coated tools is as high as 70%.

There are four types of coated tools: coated carbide tools, coated high speed steel tools, coated ceramic tools, and coated superhard materials (such as PCD and CBN).
The trees on your Louisville property are an asset and you want to be able to enjoy their beauty for years down the road. For that reason, proper tree care is crucial.
Tree pruning is a valuable service that will help you preserve the longevity of your trees. This is the process of removing dead, diseased, or damaged branches in a way that will benefit the health of the tree as a whole. There are different types of tree pruning, depending on your goals.
We know that “How to prune my tree” is a popular Google search, meaning that many people want to tackle DIY tree pruning.
While you might think you can handle this service on your own, this is not something that we’d recommend. In this article, we’ll dive into the pros and cons of both DIY tree pruning and professional tree pruning.
Pros of DIY Tree Pruning
Far and away, the main benefit of tackling tree pruning on your own is cost savings. People do not want to pay for a service that they think they can do themselves. That being said, if you make a mistake, it could cost you a lot more than you’d ever save by taking care of tree pruning on your own.
Here are what we believe homeowners would view as the primary benefits of DIY tree pruning.
- Saving Money: In general, people attempt DIY work around their home because they don’t want to pay for something they can do. But we’ll talk about why tree pruning is more complicated than people tend to realize and how a mistake can be incredibly costly.
- “Fast” Results: Another reason why homeowners might tackle DIY tree pruning is that they want the work done right away. Maybe they’re out in their yard on a Saturday and they see some branches they want taken down. They may decide rather than waiting to schedule this service with a pro, they’ll just take care of it on the spot.
Cons of DIY Tree Pruning
As we’ve mentioned, there’s a lot of risk associated with tackling tree pruning on your own. We can empathize with wanting to save money and/or wanting to take care of something right away. But with a service as potentially dangerous as tree pruning, this is simply not a DIY project.
There are a lot more cons to DIY tree pruning than there are benefits.
- You risk getting hurt: First and foremost, we want to talk about the fact that pruning is dangerous work. Every year homeowners wind up in the ER or even die because of a tree-related accident. Climbing a ladder or the tree itself to perform pruning is risky. You’re also dealing with sharp cutting tools and power equipment. If you want to prune some small shrubs or plants around your property, that’s a different story. But for your medium and tall trees, there’s quite a bit of risk.
- Pruning mistakes can be detrimental: As we’ve mentioned, there is more to pruning than people tend to realize. Pruning mistakes can be detrimental to the health of your tree and you could risk its decline or even death. Making cuts in the wrong location or making too many pruning cuts are just two examples of how things can go wrong. Pruning errors can lead to disease, pets, or other health issues.
- Pruning work is laborious and time-consuming: Another downside that we think homeowners don’t always consider is that this isn’t a quick and easy job. Proper pruning takes time and attention to detail. It can also be grueling work. There’s a good chance this isn’t how you really want to spend your free time.
- You may end up with subpar results: When your tree is properly pruned, you’ll see benefits like better growth, longer bloom times, better structure, and more. But when you make pruning mistakes or don’t have the expertise to perform this service, you’re likely to be disappointed with the results.
- You likely don’t have the proper equipment: Finally, pruning with the right tools is important. While a tree care professional will have access to all the equipment needed to do this job right, chances are, you’ll need to go out and buy more tools. Also, keep in mind that professional tree pruning is performed using commercial-grade equipment. That’s naturally going to yield better results.
Cons of Professional Tree Pruning
As you would expect, our list of cons of professional tree pruning is the exact opposite of our list of pros for DIY tree pruning.
- Tree pruning is expensive: We know a lot of people might say “tree pruning is expensive” and therefore want to tackle it themselves. But the truth is, a tree pruning mistake can cost you a lot more. Making an error that leads to the decline of your tree is costly. Or, even worse, having an accident (like a fall) that lands you in the hospital is also costly. Like most things in life, we believe that there’s a cost associated with getting high-quality work that delivers the best results.
- You’ll have to wait to schedule services: We know that people are often in a rush to get work done, particularly as the weather starts warming up and they start spending more time outside. But you have to be careful not to let impatience lead to results you’re dissatisfied with. It’s worth waiting to get on the schedule for professional tree pruning if you care about getting the best results.
Pros of Professional Tree Pruning
The pros of professional tree pruning would be the opposite of the cons of DIY tree pruning. Let’s quickly recap.
- You won’t risk getting hurt: When you let a professional handle this service, you aren’t taking any personal risk. Of course, be sure to hire a tree-pruning professional who is licensed and insured! Unfortunately, there are companies out there that don’t carry the proper licensure and insurance and that can still put you at risk!
- You won’t have to spend your free time pruning: When you hand this service over to a pro, you also free up your weekend!
- You’ll ensure the work is done right: With professional tree pruning you will get the best results which also means you’ll gain all the benefits that come with this service. You also won’t have to worry about investing in tools and other equipment as you know that a pro will have everything needed to get the job done right.
Making a Wise Choice for Tree Pruning
Hopefully, this list has given you some valuable food for thought.
We recognize that we have some bias when it comes to this topic since we are a professional tree pruning service.
That being said, we have also seen numerous mistakes over the years that could have been avoided. As professionals in this field, we do believe it is our responsibility to share why tackling DIY tree pruning can be risky and lead to costly mistakes.
In fact, sometimes we are called in to fix pruning mistakes (either from a DIY job or even an unqualified “pro”). This is not always easily done. Having seen enough hack jobs over the years that put lots of unnecessary stress on a tree, we do feel it’s our duty to stress the importance of making a wise choice.
At the end of the day, when you make the wise choice to work with a tree care professional, you’re making a valuable investment in the health of your property’s trees.
