5 reasons for carbide cutting wheels failure

Have you ever experienced an explosion of a carbide cutting wheel? Although it sounds exciting, I hope it doesn’t happen to you – it can be very dangerous! Whether you are having trouble with cutting a carbide cutting wheel, or have seen more discrepancies caused by disc cutting a carbide cutting wheel… serious… hurt and want to know how to avoid this – please read on to understand the 5 reasons for carbide cutting wheel failure.

Mismatching tool
Installing an incorrectly sized cutoff on the tool and accelerating beyond the maximum RPM will result in an annoying divorce. Just because the carbide cutting wheel fits doesn’t mean it fits the tool. For safety reasons and to prevent malfunction of the carbide cutting wheel, the size and rated speed of the tool and power tool must match.

Carbide cutting wheel Speed ​​Commands In a world where everyone wants to achieve faster/deeper/better cuts with longer life and less cost, it has been found that people are trying to use larger cutting and grinding than their tool designs. It is common for the carbide cutting wheel/grinding wheel to touch the luck. Unfortunately, the significant benefits of speed, longevity, and cost savings pose a significant threat to your safety, as this can lead to imbalances and excessive vibrations – leading to control failures and even tool failures.

Solution: The recommended best practice is to always keep the shield in place while operating the tool. This prevents installation and use of erroneous carbide cutting wheels.

The speed of the power tool affects the performance of the carbide cutting wheel and the safety of the operator.

Solution: Do not install the carbide cutting wheel if the marking speed on the power tool is higher than the maximum RPM specified on the abrasive. Do not exceed the maximum RPM indicated on the carbide cutting wheel. These are the maximum RPMs the disc can run without any manipulation (free spins). This is a safety indication for the user, not the recommended speed.

2. Apply too much pressure
Put too much pressure on anything, and eventually it will explode…

Thin carbide cutting wheel When you want the tool to cut faster / deeper / better, it is human nature to apply more pressure to it. However, this will actually achieve the opposite effect and reduce performance and risk security. The extra pressure will blunt the particles of the carbide cutting wheel faster and the heat will build up, causing the carbide cutting wheel to break down (fail) faster.

Solution: For best performance, it’s best to apply the right pressure and let the tool do all the work.

How do you know that the pressure you applied is too great? There are strong indications that RPM will fall. If you hear a drop in the RPM of the tool, or if you feel the motor is strained and stuck, it may be that you are under excessive pressure.

3. Change the angle
Cutting the disc angle The position and angle of the tool relative to the workpiece will vary depending on the type of abrasive used. Surprisingly, a few degrees of variation can make a big difference! Even if the angle is changed by a few degrees, a large amount of stress may be applied to the abrasive, resulting in performance degradation and possible product failure.

Solution: The carbide cutting wheel and the cutting wheel should be used at a 90° angle perpendicular to the workpiece.

4. Wear date and expiration date
Carbide cutting wheel fail-safe glass Unfortunately, unlike the eternal plug, we have not found a carbide cutting wheel that can be used permanently. In fact, they have a maximum service life of 3 years from the start of manufacture (and therefore have an expiration date), and once used, they will eventually fail. As the carbide cutting wheel wears, the diameter decreases, which naturally allows the operator to adjust its cutting angle and/or increase the pressure to maintain the same cutting effect. As mentioned above, this will actually result in faster damage to the carbide cutting wheel, which will tighten the tool and cause a malfunction. This can be very dangerous because the carbide cutting wheel breaks during use and you will project very sharp fragments at high speed.

Solution: Record the expiration date of the product (usually see the expiration date on the center ring of the disc, the format is month and year (eg 03/2022). Smaller or acyclic discs may print the date on the package , on the carbide cutting wheel label, even on the carbide cutting wheel itself, and check the carbide cutting wheel for signs of damage and/or wear before each use. Do not install damaged or expired carbide cutting wheels.

5. Incorrect storage
The carbide cutting wheel is made by bonding the abrasive together using a resin. Over time, the resin will absorb moisture, which will cause the cut or ground disc to deteriorate, resulting in damage to the abrasive cut off wheel.

Solution: The best practice is to store the cutting and carbide cutting wheels in a clean, dry location away from water or chemicals and do not expose them to frost or high humidity. Ideal situation
