In contrast, rip blades have aggressive hook angles, usually 10, 15 or even 25 degrees. The positive hook angle allows rip blades to plow through the stock with a lot less feed pressure. I don't recommend that you use a RA for ripping because the increased feed pressure required. Instead, I recommend one of the Amana rip blades such as the no. Each of these blades has a 20 degree positive hook angle for decreased feed pressure.
Since we're on the topic, for reasons of your personal safety, I recommend that you do not use a radial arm saw for ripping. Instead, I recommend that you use a table saw for ripping. Unlike a radial arm saw, the height of the blade on a table saw can be lowered so that only enough blade is exposed for the thickness of the stock.
However, we know from experience that a slight negative hookfor the radial arm saw maybe 3 to 6 degrees negative will actually work thebest. The operator will have to use a little effort to pull the saw into thewood, but the saw will not pull itself. This is indeed a safe procedure. Butlet me repeat that such a saw blade used on a table or ripsaw will push thewood away from the blade toward the operator, so do not use negative hook forthose saws.
Do wewant the saw to pull itself into the wood perhaps it would be out of control alittle bit? So again, zero or negative hook, but not too much negative asthen the saw will be hard to feed and will jump back. Consider a bandsaw—if the saw has a positive hook, then it is pullingitself toward the wood and it might pull itself off the wheels as it grabs intothe wood, which is a disaster.
So, a bandsaw will have zero or slightlynegative hook. Gene Wengert, "The Wood Doctor," has been training people in efficient use of wood for 35 years. He is extension specialist emeritus at the University of Wisconsin-Madison. Have something to say? Share your thoughts with us in the comments below. Wood Dr. Hook angle refers to the amount of lean forward or backward each tooth has. In other words, a hook angle is a specific angle at which the tip of any blade enters.
Suppose you encounter a blade that has a degree positive hook angle, what does that mean? In this case, the blade will enter into any material at a degree angle. In most cases, 5 to degree hook angles are considered as standard where the stripper ones can range up to 18 to 22 degrees.
Softer metals can be easily cut or ripped using these types. But usually, hard metals require a swallow 6 degrees. Hopefully, now you understand where a positive hook angle is recommended. But what about the negative hook angle? Yeah, you got it right! A negative hook angle is required where you want a gentle cut. In most cases, a degree hook angle is used to reduce the risk. This also ensures overall control over the tool.
If you deal with cuts that require precision and extra care, you should go with blades that simply have more teeth. An element of such blades is that they tend to cut slowly.
But for this, you can have better control over your tool. Nevertheless, as you can guess from the earlier discussion, you need blades that have more teeth and of course, a negative hook angle can be a good option for precise cutting.
The arrangement can be of different types. You can extract some extra benefits from the blades if you know their saw tip arrangements. Why is this configuration important? Simply because you can use these blades for general purposes. This grind also ensures durability. Okay, what are the specs? You can notice that the tops of alternating teeth are beveled. It can be approximately 15 degrees. This combination rewards you by giving sharper edges. You can enjoy a better cut quality and of course no chipping or splinters.
An added benefit with the first one is available with this type! You can grind the face and can do it with an angle. A better example can be an arrangement of 4 ATB then 1 raker. Here, the raker tooth is inserted to ensure that the V-shaped piece of material which is left in the center is removed. This provides you with a smoother cut. Plus, the raker helps the blade to run straight. As you know, the blades tend to heat up during operation.
The best way to decide the right material of the blade is to learn about the carbide used to build the blade. You can find whether professional-grade carbide is used or not in the blade from the specs provided by the manufacturers. Why did these make it to the list? Concord Blades offers a wide range of various blades to enable you to choose the best fit for your beloved radial arm saw.
These blades not only deliver precise cutting but also promise durability. This blade contains a lower amount of iron, making it perfect for cutting non-ferrous items such as plastic, plexiglass, fiberglass, PVC, and acrylic. This blade is built to last and will prolong the life of your favorite radial arm saw. Its versatility also means that it can also be used for other types of saw so this is the only blade you will ever need. This feature also ensures long-term use and gives a fine cut every time.
This ensures an even finer cut and prevents the damage of wood. A 5-degree hook is added for further safety. A few downsides to mention are that some users have complained that this blade tends to get slightly imbalanced, and another reported issue is that it loses its edges quickly compared to other blades.
Check prices and availability here. Its improved design is even more ergonomic for easy use. It can fit with any saw and can render amazing performance for a long time. Teeth variants include 48, 60 and 72 and a thin kerf variant is also available. This allows for easy removal of chips and also reduces tear-out. Furthermore, this type of blade has a sharper edge and ensures a fine cut which results in less wood waste.
The manufacturer has equipped the blade with a crosscutting blend containing premium high-density carbide. This feature enables the blade to render a better cutting experience. Do you ever notice a climb of the blade during cutting? This occurs because of the hook angle. It also lengthens the service life of this blade by providing protection against rust.
Plus, this coating ensures less pitch-up during the operation. A negative to mention is that the blade gradually loses its sharp edge and some users have noticed this change after a relatively short period. Check the latest prices here. If you work with different types of wood pieces and need precise cutting, this blade can meet your needs.
With its extraordinary features, this radial arm saw blade can ensure proper cutting.
