Frequently asked
Questions

You list different types of blades such as rip and crosscut. Can’t I just use a universal blade?

Each blade tooth has a specific geometry which relates to the angle at which the blade will come into contact with the material you are cutting. Both crosscut and rip saw are specifically describing the way in which you will be cutting your wood. Crosscut is designed to cut perpendicular to the grain, this means unlike a rip saw it will have to be cutting the wood which will mean a change in geometry as to how the sawblade contacts the wood as well as it’s frequency of contact.   A rip saw as it’s name would suggest allows for longer strides allowing the wood to work with the saw blade to tear with the grain. 

I can get a blade, the same blade but much cheaper from another company. Is there any difference in the blades or are yours just expensive?

Our blades are made using the highest standards. The raw materials used are the highest quality materials used in the circular saw blade industry. The steel used in the saw bodies conform to the highest German standards for circular saw steel.

Our blades only use the highest quality of tungsten carbide sourced from Europe using specific grades for different applications. Once again all of our carbide tips conform and surpass international standards.

If you look at the photo to the right you can clearly see the difference in tip size on the two blades (our Tru-Cut range to the left). This equates to life of the blade in terms of the number of times that the blade’s tips can be sharpened. This however requires the saw body to be made from the correct material to retain the tension to ensure that your saw lasts for the entire lifetime of the tools.   

When should my saw blade be sharpened?

Dependent on the function of your sawblade and frequency of its use so too will sharpening process be needed. The range of frequency can vary from 20 – 250 000 cuts, dependent on type of blade, HSS, TCT etc and the material being cut. Tool steels vs wood for example.  

Can I sharpen my own saw blades?

Sawblades have different pitch angles and bevel directions, for you to do the blade true justice to work best for you we do not advise this.

Consider a recondition on your blade which we will not only sharpen your blade but re-align it too.

Can my saw blade be sharpened?


A saw blade may be a plate saw which yes dependent on body condition of sawblade it may be sharpened.

Some sawblades are Tungsten Carbide Tipped which dependent on body condition, and size of carbide tip left on saw blade will be factors assessing if blade should be sharpened again or not. 

Do you repair saw blades?

Yes, we have a strong team and years of knowledge backed up by advanced processes and machinery to assess and repair most sawblades.


We work in conjunction with some of the world’s best tungsten carbide

What are the different grades of tungsten carbide used and why?

manufacturers to select grades that are ideally suited to cutting different materials and various applications.

Tungsten carbide is available in various grades. Some common grades used for circular saw blades are K10; K20; P45. However these are all standard ISO denotations with a massive range. Saw tips are generally more refined and conform to narrower specifications. For example a KCr10/WK10m saw tip is very good for woodcutting however it would simply shatter in a steel cutting application.
All grades differ in hardness, fracture toughness, density, corrosion resistance, binder percentage, binder composition and grain size.

Can I use the same blade for different materials?

Blades are made specific in their geometry to best meet the function prescribed. As much as it is not advised for continual use on the wrong material a quick cut here or there would be dependent on the material you choose to cut. If you would need a blade to cut varying materials let’s see which blade would make the best compromises for your assorted materials.
Can I get blades with a different bore size?

The standard bore size is 30mm and is often the universal choice of machine builds.   We can of course customize your saw blade to your specific requirements.

Are non-ferrous blades always a negative hook angle?

Non-ferrous blades refer to the cutting of non-ferrous metals such as aluminium, brass, copper and lead. Dependent on the type of machine you are using the hook can vary between -10 and +10 dependent on the application. Negative will always work but positive cuts more freely. However please be aware that in some machines if you are climb cutting, a positive hook will pull into the blade and be dangerous.  We are always on hand to advise where possible.

What are the slots (tension slots) in saw blades for?

Tension slots enable the rim of the saw blade to expand due to heating without effecting the tension in a saw blade, This mainly occurs during brazing of the tips however it can occur in certain cutting applications where the rim of the blade heats up.

What does the pinhole location listed in your products mean?

2 / 7 / 42
+
2 / 9.5 / 46.5
+
2 / 10 / 60

On our products we list the number of pinholes, pinhole diameter and the PCD (pinhole centre diameter).

For example the description of 2/7/42 would be 2 pinholes of 7mm diameter on a PCD of 42mm .There are usually 2 slots made up of 3 pinholes each.

Can I use my woodworking sawing machine to cut steel with one of your steel cutting blades?

No, a woodworking saw machine is totally different to a steel cutting machine. Woodworking machines run at a much higher speed than steel cutting machines. Steel cutting machines will also have backlash and vibration limiting mechanisms built into the saw drive to eliminate chipping on the carbide tooth. If you were to try to cut steel in standard cut-off saw designed for wood you would simply smash all the carbide tips on steel cutting saw blade,

Can you weld a crack in my saw blade?

No, safety regulations do not allow for welding of a circular saw body.

This is due to the fact that circular saw bodies are manufactured from a high carbon steel which has very poor weldability. While a highly qualified welder can successfully weld this material, in general if it is welded, the material immediately surrounding the weld hardens and becomes very brittle resulting in new cracks forming and the possibility of the entire saw blade breaking into pieces.

I don’t know how many teeth I need on my blade. How do I decide this?

General rule would be the lower number of teeth the rougher the cut will be, conversely by increasing the number of teeth so too will your cut be smoother.

For example if you are cross-cutting your firewood you don’t need a fine finish. You would select the coarsest tooth blade suitable for the diameter of branch / log you are cutting.  

However if you are making furniture, the finer your cut the less surface finishing i.e.: sanding is required on your your product. So you would want a high number of teeth. It must be noted, too many teeth can lead to rubbing rather than cutting which will blunten the saw blade and burn your edge.


Can my buckled
saw blade
be repaired?

Saw blades can be straightened and tensioned and should always be checked for straightening and tensioning anytime they are sharpened.
If your blade is extremely buckled it may require a re-tempering process to remove built up stresses and in this case one would need to look at it carefully to see if the cost of this process is viable.
Please note re-tempering would involve re-tipping.

Do high speed steel (HSS) saw blades turn at high speed?

This is a common error in peoples understanding the term. High Speed Steel refers to the rate at which steel can be removed. 

This term originally coined during the development of Alloy Tool Steel common now known as High Speed Steel

what speed should my saw blade be running at?

Dependent on the type of saw blade and material being cut, speeds can vary greatly.

On a wood cutting TCT blade you would generally run between 40m/s and 60m/s.

Under useful information you will also find a general speed chart to use as a guideline, however for special applications please feel free to contact us for detailed information.
