Cold Saw Blade Guide – 8 Answers About the Problems you can’t Avoid

Nowadays, it is not enough to own a Cold saw blade; you must do well to master the use. Beyond this, there arises a dire need to be able to troubleshoot simple problems.

The ability to effectively troubleshoot these problems and solve them makes you a master of the Cold saw blade. Instead of this, we have decided to curate this article to serve as a guide through troubleshooting and correction.

In subsequent paragraphs, you would find answers to problems most Cold saw blade users encounter.

1.What is a cold saw blade?

A Cold saw blade used for cutting metals at low speed; however, its uniqueness lies in the teeth design. The teeth design is such that heat is dissipated quickly to the chips generated during cutting. In turn, it helps keep the temperature of both the blade and workpiece in check and prevent overheating.

Cold saw blades used for cutting ferrous and non-ferrous metals. You stand to gain more when you use the cold saw blade. Your blade and workpiece remain cool all through cutting; this implies that minimal discolouration and sparks occur.

Presently, there are two prominent types of the Cold saw blade- High-speed steel (HSS) and Tungsten Carbide-tipped (TCT). Interestingly both types of blades are re-sharpenable when they become dull. For the HSS blades, they cut ferrous metals in the form of tubes, bars, castings, etc. seamlessly at about 350 SFM. HSS blades cut very well without generation heat and high resistance to wear. TCT blades are every hard, and therefore cannot resist shock as much as HSS blades do. However, it cuts faster than HSS blades at a moderate chip load per tooth. TCT blades are primarily for cutting non-ferrous metal but can do well with cutting ferrous metal as well.

2.How to use the cold saw blade correctly?

The key secret to enjoying and reaping the full advantages of the cold saw blade lies in the correct usage. Highlighted below are the simple hacks, that can help you derive the maximum utility of a cold saw blade:

Allow the blade to do the work- This simply means you should not in any way force the saw blade through the workpiece. Instead, you allow the blade cut through progressively without putting pressure or rushing it through the workpiece.

Regulate the speed of cold saw blade- Here, you would want to pay attention to the nature of metal you are cutting. The speed needed varies from metal to metal. Cutting of brittle materials must be kept and maintained at a low rotational speed. Consult the manufacturer’s guide to get the exact speed needed for the metal you want to cut.

Clean and Lubricate the Cold saw blade- Application of lubricant on the Cold saw blade goes a long way in helping it function well. It rapidly decreases friction and consequently overheating. Furthermore, cleaning the surface of the blade will help to keep debris out. The presence of debris could interfere with jobs, harm the operator, or damage the workpiece.

Take Safety Measures- There are general safety procedures expected to follow when operating the Cold saw blade. These includes:

  • Wearing safety gears to protect the sensitive part of the body
  • You are positioning yourself appropriately when operating.
  • Concentrate on the job at hand by avoiding distractions.

3.How to change the blade in Baileigh cold cut saw?

a.Remove the hexagonal socket screw to release the mobile guard.

b.Position a wooden block into the vice.

c.Gently rest the machine head in the block of wood.

d.Remove the lock bolt with a hex wrench in the clockwise direction due to the left-handed screw.

e.Dismount the blade and washer from the spindle.

f.Mount the new blade and repeat the process from a-e above.

g.Re-confirm that the blade is firmly in place and ready to cut.

By following the steps above, you assured of a perfect replacement of your blade on the Baileigh cold cut saw.

4.Why is my cold cut saw blade jumping while cutting?

Jumping is also known as kickbacks; from experience, several reasons could cause this unfortunate setback. But not to worry, we have got a handful of hacks to help you solve such problems.

Firstly, ensure the vertical motion of your blade is maintained orthogonally to the axis of rotation. Secondly, proper placement of the workpiece on the cold cut saw blade jumping.

Furthermore, a blunt cold saw blade is a valid reason for jumping to occur. Therefore, you must make sure your blade always kept sharp. Again, rushing the cold saw blade through the workpiece could bring about jumping. It is the more reason why it is advisable to let the Cold saw blade do the work.

Lastly, ensure the Cold saw blade’s base is bolted well to the ground, and the electric motor is in good shape.

5.How long do cold cut saw blades last?

No matter how much care you give to your blade, a time eventually comes when it needs to be changed. On average, a typical cold saw blade should last at least six months.

You can usually run a quick diagnostic check to determine the need for resharpening your cold saw blade. Among these checks are the following:

Frequent tearing out during cutting

Excessive chipping

Damaged teeth.

Inability to follow cut line

Blunt teeth

Typically, a cold saw blade can complete between 800 to 1000 cuts before totally wearing out. Also, during their lifespan, you can sharpen them up to 30 to 40 times. Although, other factors could prompt resharpening even if the blade has not completed 800 to 1000 cuts.

Therefore, we advise that you study your usage frequency and draft a suitable plan to follow. Your ability to develop a working plan will help you to use the blade effectively without any disappointment.

6.Where to get cold saw blade sharpening?

You can easily get cold cutting saw blades in NCCuttingtools. All you need to do is schedule meetings and date them.
The cost of grinding always depends mainly on the diameter and number of teeth of the Cold saw blade. Only when the saw blade is in terrible shape does the additional cost need to be paid, which requires additional work.

Pricing and Costing

The overall cost of sharpening a typical cold saw blades $10 to $20 for a 10 to 14-inch diameter cold saw blade. Prices vary with the diameter and number of teeth of the blade. In the business of cold saw blade sharpening, the cost of sharpening an HSS-tipped cold saw blade solely based on the blade diameter, while for a carbide-tipped blade, the price is dependent on the number of teeth. In simpler terms, it means that a 20″ or 100″ carbide-tipped blade would cost the same to sharpen but differ if it is an HSS-tipped. As the number of blades that you intend to sharpen increases, so does the discount you get on the price.

7.What factors affect sharpening?

Cold Saw blade tip & nature of metal

As discussed earlier, the Cold saw blade tip finished with either HSS or TCT. While HSS tipped blades are usually easy to sharpen, their cutting ability is often lower than that of TCT. One other fact about TCT is that it is very hard, and this simply implies that sharpening will seem tedious.

On the other hand, the nature of metal to be cut with the Cold saw blade informs the sharpening. A cold saw blade used for steel cutting would require a different degree of sharpness than that used for diamonds.

What to pay attention to when sharpening?

Endeavour to pay rapt attention paid to the tooth thickness and hook angle. The hook angle mostly has to do with the extent to which the Cold saw blade engages the workpiece.

What to avoid when sharpening?

As much as using the automated method to sharpen is encouraged, some users still prefer to do it themselves. In doing this, you have to take some precautions when carrying it out:

1.Switch off and disconnect the Cold saw power cable from the mains.

2.Ensure that you evenly file the teeth to prevent wobbling.

3.Use safety gear to prevent chips from entering into your eye, as it is usually hot.

8.What is needed to sharpen a cold chop saw blade?

A cold chop saw blade is similar to a mitre saw in look and appearance. The significant difference lies in the ability of the mitre saw to make both straight and angled cut. To sharpen the cold chop saw blade, what is needed depends on the method used to grind. While the automated CNC sharpening method is left for the professionals to decide, the do-it-yourself approach differs.

To do it yourself, you need to prepare the blade, and subsequently get yourself a sharpening tool set.
