The most common way to cut hardened steel is by sawing or grinding. Sawing is done with a hacksaw, band saw, jigsaw, or circ saw, while grinding is done with an angle grinder, belt sander, disc sander, or die grinder.
It is important that the proper tools be used to cut hardened steel so that the tool does not become damaged and the steel is not ruined. Additionally, working with higher-speed cutting tools, such as turbo-style angle grinders, can make cutting hardened steel easier.
In some cases, specially designed blades for hardened steel or diamond blades may be required for successful cutting with a saw. For grinding, abrasive discs that are designed for hardened steel are typically the best choice.
High-speed cutting devices should also be used when grinding hardened steel. When cutting and grinding hardened steel, safety should always be a priority. Protective gear, such as safety glasses, heavy-duty gloves, and a dust mask, should be worn.
Also, any sparks created during the cutting process should be contained and secured to avoid potential injury or fires.
Can you angle grind hardened steel?
Yes, it is possible to angle grind hardened steel. The key is to make sure you use the correct grinding wheel and that the wheel is in good condition. The wheel should be made from an abrasive material suitable for grinding hardened steel and should be “dressed” to remove any metal burrs or pave that could otherwise cause the wheel to clog or wear rapidly.
When angle grinding hardened steel, you should be aware that the pressure applied to the wheel can cause it to heat up, making it harder to control and potentially creating sparks and debris which can be a hazard.
It is recommended to maintain a consistent speed and reduce pressure if necessary in order to avoid having to start over with a new wheel. Additionally, the use of protective face and eye gear is highly recommended.
With these precautions taken, it is possible to angle grind hardened steel.
