Features to Consider When Choosing a Bench Grinder
Is a Work Light Helpful on a Bench Grinder?
A work light is a great feature to use with any type of power tool. This is an important safety feature that can illuminate your work area so that you don’t injure yourself. Work lights can be flexible and directly attached at the center of the machine, it may be built in directly to the machine, or it might be attached over each wheel.
What Wheel Options Do You Need with a Bench Grinder?
You want a number of wheel options when choosing a bench grinder. It might only come with most of the wheel options but you at least want a fine or medium wheel as well as a coarse wheel. Before you purchase a unit, check and see which wheels it comes with as well as the size wheels that will fit it if you plan on make accessories or after-market add-ons.
Avoid something that only has a few wheels available and makes sure to check and see what materials the wheels are made with. If you plan to grind steel, you want a wheel with vitrified aluminum oxide or, if you working with nonferrous materials or cast iron, you want a silicon carbide wheel. Depending on your personal preferences and the materials you are working with, you will have a large range of stones to choose from.
What Size Bench Grinder is Best?
When it comes to bench grinders, there are a lot of different sizes to choose from. Miniature options start at 3 inches while larger bench grinder can go all the way up to 8 inches with lots of grinders falling in at 6 inches. Make sure to consider the type of projects you will be doing and decide from there which of the wheel sizes will work best with those projects. Whether you choose a small or large bench grinder will depend on your own personal preferences and the jobs you have planned.
What Speed Should I Look for in a Bench Grinder?
The overall speed of the machine is one of the most important considerations when choosing a bench grinder. You want to make sure you will have enough speed to get the job done, so the faster it spins the faster you will be able to finish the job. Most bench grinders will give you between 3,000 and 3,600 RPMs, so make sure you get a machine that can at least go that fast.
Make sure you don’t get something that is stronger than what you need but is at least strong enough to do what you need. You can also find units with variable speed options that will increase your versatility so you can change from low to high power as you need it.
Why Should You Have Water Handy?
You can ruin a tool’s edge if you overheat it, so keeping water nearby will make it easy to cool off the tool. It will turn bluish black if it becomes too hot, then you will need to grind the edge back to the good steel to start over again. The best method to sharpen a tool is moving it over the grinder once for only a couple of seconds and then stick the tool in water so you won’t risk ruining the tool.
How Do You Safely Grind a Small Object?
Use locking pliers to hold a small object to keep your finger a good way away from the wheel while it grinds. This protects them from getting burned by the hot object and provides control of the process.
What Speed Grinder is Best for Sharpening?
Most grinder run at around 3,450 RPMs unless they have variable speed. Make sure to keep your wheels dressed so that your grinder will work well, but when sharpening, you want a grinder with low-speed to run about 1,750 RPMS. This will lessen the chance that the edge will overheat.
What Does It Mean to Dress the Wheels?
Wheel dressing means you square the wheel’s face and uncover new grit so you have more effective cutting. A used wheel can become blocked and dull the grit which can slow material removal and cause overheating. Wheel dressers will cut away the surface of the wheel to uncover new grit while rounding the wheel and squaring the face.
How Can You Tell When a Tool is Sharp Enough?
The edge of a tool is becoming sharp when you see a spark. When you have a blunt edge, the spark go down but as it becomes sharper, the spark will flow over the tool and down the surface that is facing you.
How Do You Create an Angle Gauge?
Using an inexpensive protractor, you can create an angle gauge with a thin cardboard. First, draw the angle onto the cardboard using the protractor making sure your angle is labeled and cut following the line to create a gauge. Next, the tool rest should be adjusted by placing the cardboard on it and adjusting the angle until the wheel is contacting the middle of the angle on the cardboard gauge.
Can You Upgrade the Tool Rest?
You can easily add a stand-alone tool rest by purchasing one from a woodworking store. You can also purchase an attachment that will hold a chisel or plane irons.
How Can You Make a Portable Grinder?
You mount a grinder to a small stand or board so you can attach it to the bench when you need to use it and then store it away when you are done.
What is a Polishing Station?
A polishing station is basically when you have fitted a cotton buffing wheel to one side of a bench grinder and a wire wheel on the other side. It can also have a buffing wheel on both sides which makes a great cleaning and polishing tool. Polishing compound sticks are also needed which are color-coded so you know if they have coarse to very fine grit. When using a polishing wheel, the polishing stick is held against the buffing wheel to transfer the polishing compound to the buffing wheel which will buff whatever object you hold against it.
How Do You Use a Grinder Safely?
• Check grinder wheels for damage or cracks
• Wear goggles, face shield, or safety glasses that have side shields when grinding
• Don’t overtighten the nut when installing a wheel which can crack it
• Keep a gap of 1/8 inch or less between the grinding wheel and the tool rest
• Make sure to keep the spark shield and shrouds in place
When looking at the best options for a bench grinder, make sure to check out all the features and find one that matches the projects you have planned. Make sure to find one that has enough power and the right type of wheels to get the job done right the first time.
