Buyer's Guide: Considerable factors while buying a die grinder for wood
As you have checked above, die grinders are of different categories in terms of collet size, power source and others. While some have ¼ inch collect, the others have ⅛ inch collect.
The former can support a couple of bits but the latter, being a smaller unit, doesn't support multiple bit installation. However, it can support tasks really well. Furthermore, the higher range of RPM, incredible power source, etc. are yet to be discussed in the following table.
But, before proceeding further, you must be sure about the type of job for which you are here. Plus, the cost of your chosen model might play a significant role while making the end decision, but here are the priority factors:
The general size of a die grinder collect is ¼ inch. This is much better than the smaller die grinder of ⅛ inch collect as the former allows swapping a range of bits of different sizes. However, the second type is also good at performing tasks well, but the usage here is limited.
The most-sought extensions are generally available on the market in a set of 8. While some brands sell this set in the standard package along with the die grinder, in most cases, you have to buy this set separately. So, check the brand that you chose. In a standard set, it includes die grinders of varied diameters and angles, and metal sanders for buffing.
Die grinders could be cordless, corded electric, and pneumatic counterparts. Choosing which version is workable for you depends on some specific variables. But, assessing which version is right for your work is the most important point.
If you already have an air compressor in your woodshop, buying a pneumatic die grinder would be a smart choice. If you prefer a portable wireless grinder model, go for the cordless one. This type of die grinder is driven by high power batteries.
Note: The cordless option is specifically for occasional use only as the battery life is not fairly high.
Corded-electric die grinder is a bit costlier compared to the above two types as it is the easiest one to use. Plus, a corded model is suitable for prolonged and extensive use on a daily basis. Whereas the cordless and pneumatic ones remain active only till there is enough battery life and sufficient air in the compressor, respectively. Whichever you choose, you need to know about its maneuverability.
The power rating of an electric die grinder should at least range between (18 to 20) Volts. The pneumatic one has a power rating between (¼ to ½) HorsePower. Whichever type you pick, go for the one with the highest power range as it ensures better user performance.
This factor depends on the type of surface on which you will be using the grinder. If it is a hardwood material, you need to use the grinder that delivers maximum speed control range. However, you must keep the history limit at a recommended limit of 20,000 RPM. If it is a softwood surface (wood board), use a lower speed control die grinder.
Note: 90 degree die grinder is best for buffing as you can apply more pressure to the backside of the grinder handles, thereby fast pacing the buffing process and enhancing the shine quality.
These two variables are crucial if you are planning to buy a pneumatic die grinder. Check if the air compressor delivers the required CFM at an appropriate PSI level. The capacity of the compressor to deliver maximum air flow depends on the power supply that drives the die grinder. Also, make sure to select a compressor that is workable at minimal pressure and volume to prevent stalling of the grinder motor.
Check which grinder type brings you the maximum comfort and select the model accordingly. For instance, if you are looking for a regular-using die grinder, make sure to check on the lightweight and grinder size. If you are buying a pneumatic grinder, make sure you have a proper position to locate its exhaust vent so that it does not affect your health.
Note: A front-facing exhaust vent keeps the work area clean. However, if you are using oil on the work, the forward vent may end up creating a mess.
Do not forget to count on the safety features like accidental motor crank, done by children or other novice people who somehow gained access to the device. This is the reason, some professionals prefer buying the grinder model that has a simple on/off button.
Grinder vibration during its operation is another considerable attribute. While some motors vibrate more than the work it is meant for, some work smoothly with minimal vibration. If you are an occasional user or require a grinder for shorter wood tasks, then vibration is not an issue. Else, it is a hassle for the professionals to work with a high-vibrating motor grinder for long-duration.
A compact cum lightweight model is what most users prefer, as it is easy to carry around and store. It also saves your time in lifting the tool and moving it constantly without feeling fatigue. However, for heavy woodworks, a handy grinder is not a great choice. In that case, you must look for a sturdy and larger grinder that could smoothly work on the hardwood surface.
All the die grinder models discussed above are unique and most-sought models of 2020. But, you must pick the one that suits your convenience.
