Bench Grinder Buyer’s Guide
Before you go off and choose a Bench Grinder take a look at its main features below to make sure you make the right choice!
Coarse & fine grinding wheels
The main feature of a bench grinder is of course its grinding wheels. Coarse and fine wheels are often used in conjunction with one another.
A coarse wheel removes more material faster but won’t leave a clean finish. So for shaping metal, for instance, the coarse wheel removes bulk and creates a shape, then the finer wheel can be used for cleaning the piece.
One of the most common uses of the fine wheel is for maintaining tools and creating clean, sharp edges on them.
Wheel / stone guard
The grinding wheel or stone produces sparks and debris when grinding. Most grinders come with a protective guard that is positioned near the wheels to help catch the bulk of the waste material and protect against the sparks.
Regardless of the function of the guard always wear eye protection.
A strong and sturdy tool rest is a very important component of your grinding operation. The tool rest needs to be fully adjustable in terms of angle and tilt in order to optimise the tool’s positioning for sharpening. The tool rest also needs to be large enough to accommodate whatever you plan to work with.
Rubber foot pads
Rubber footprints ensure that the grinder stays secure on the work bench. The grinder must remain stable and still, especially under heavy loads, particularly as the grinding process can create a lot of vibration on the bench.
Bench mounting holes
Better still than rubber foot pads, having good bench mounting holes and fixings ensures the grinder fits securely to the bench, minimising the risk of slippage and injury.
What is a bench grinder?
A bench grinder consists of 2 grinding wheels that rotate at speed – one wheel is coarse and one is fine. Material that requires grinding is offered up to either or both wheels for removal of surplus debris and further refinement into the finished object.
The grinder can also be used to sharpen, buff, polish or clean up rusty or tarnished metal. It is also very good for tool maintenance, enabling you for example to sharpen knives and chisels with relative ease compared to using a whetstone.
How do I use a bench grinder?
If you have never used a bench grinder before a great way to practice your skills is to shape a scrap piece of metal.
Firstly ensure you are properly protected. Both the grinder and the piece of metal may shoot debris towards you. Therefore, it is important to wear eye protection, a leather apron, and gloves.
Then, you need to check the machine is fit for purpose. Ensure the wheel is correctly mounted and secure so it spins properly and won’t fly off the grinder. You will also need to ensure the tool rest is securely positioned beside the wheel. And if you are grinding for any length of time (over 30 seconds) the metal will heat up so make sure the bench grinder’s water tray is topped up or have a bucket of water nearby.
Once all safety checks are done the fun part begins! Turn on the machine and begin to shape your metal.
Ensure you grip the metal with both hands. Lay the piece on the tool rest and slowly press against the wheel of the grinder. You want to let the machine do the work so there is no need to put excess force on the metal against the wheel. Never position your work piece on the side of the wheel as this will damage it.
As the machine starts to shape the metal experiment by moving it around and trying to create different shapes and curves.
Dip your work piece in the water regularly to keep it cool. Every 40 seconds should be enough.
