When you're using mills regularly it can be laborious changing devices all the time. When these red Milwaukee mills were on sale, I bought two. I can set up a cutting disk in one mill and a grinding wheel or a sanding disk in another one. This speeds up my workflow.
This was great for big heavy tasks like concrete and approximately cutting up large steel sections. There is no 'skill' with a 9-inch grinder, so it's not ideal for bike work (what size angle grinder to cut paving slabs). Don't waste your money unless you have other needs for it. Bigger is not better in this case. Some time later on, I bought this 5-inch angle grinder.
This is a common size used on older motorcycles, along with 3/4 and 7/8, or 19mm and 22mm for the metric world. If you're cutting this tubing utilizing a 4-inch grinder, you might just get three-quarters of the way through and after that you have to reverse and cut from the opposite.
The accessories are a bit more expensive, clearly, but they do last a longer than the 4-inch ones. I often leave a cutting disc in my 5-inch grinder and leave the 4-inch mills for other tasks. Purchase an inexpensive 4-inch grinder first. If you pick to acquire a 2nd grinder, consider a 5-inch mill if cutting tube is a common job.
This specific mill's set up with the cutting wheel, or a cutting blade. The one-millimeters are my favorite: They permit you to cut through tube easily, quickly and with a thin 'kerf' (which is the thickness of the cut). Bosch makes these specific ones, and I simply buy another box of 10 when they're on sale at my regional hardware store.
The other accessory that I discover extremely useful is a 'flap disk' or a sanding disk. A flap disk is a selection of sanding pads bonded to a backing plate, available in a series of abrasive grits. As they are used, the edge of the pad uses away to expose more abrasive.
Again, this specific one's Bosch, but just due to the fact that it's the brand my local shop stocks. They aren't cheapin Australia they cost around about $7 to $8 each, however they do last rather a while. And they are really beneficial when working on a motorbike. I prefer to buy 100 grit or 120 grit.
Among my 4-inch grinders is constantly established with a flap disc. I do not generally use grinding disks on motorcycle jobs. Comparable to the coarse grit flap wheels, I think a grinding disc is a very aggressive method of getting rid of metal. how to dress a grinding wheel on a side angle grinder. I tend to select a finer-grit flap disk prior to I would utilize a grinding disk.
On my old Makita grinder, I've permanently set up a wire wheel. This is one of my go-to tools for stripping paint or cleansing rust off surfaces. As the wire bristles spin, they smash paint and rust off a steel surface without significant damage. Steel bristles are harder than aluminum, so they will damage an aluminum surface area.
This mill is used solely with a wire wheel (how to cut tiles with an angle grinder). Considering that the wire wheel is much heavier than a cutting disc, it puts a more load on the electric motor and will most likely speed up the grinder's eventual demise! Together with the wire wheel, my other preferred paint-removal accessory is the paint-stripping disc.
The ones I buy locally are referred to as 'silicon impregnated abrasive nylon.' These are terrific for bike work, especially for bigger, flatter surface areas, such as fenders and gas tanks. With an angle grinder, a paint removing disc and a wire wheel, you can eliminate paint from an entire bike. Would it be quicker to send it for sand blasting or dipping? Sure, but you can do it in your home at low-cost with these tools (how to cut a 230mm angle grinder).
I have actually removed a number of tanks and fenders with these wheels, and in my non-scientific tests, I find the 5-inch version lasts a lot longer than the 4-inch version. This would recommend its more economical to purchase these in 5-inch if you have a 5-inch mill. Comparable in building and construction to a flap wheel, synthetic non-woven flap discs contain a polymer abrasive instead of an abrasive particle pad - what size angle grinder to cut paving slabs. how much current for a four and a half inch angle grinder.
They are much less aggressive than a sanding flap disc, so they're relatively safe to use on aluminum surface areas. I've been try out sanding disks which need backing plate. I was questioning whether it would be more affordable to use something like this than to spend for a sanding flap disk - what size angle grinder to cut paving slabs.
You appear to get much more material removed with a flap disc. I think this is due to the flap disc exposing new abrasive as it wears. When these sanding discs are used, they go in the trash. It was simply an experiment to see what would take place. Stick with flap wheels if you can.
There's certainly a big potential for accidents with mills. However if you take a few fundamental precautions, you can reduce that potential. Match your devices to the spindle on the angle mill. The product packaging or directions will specify the bore (the hole in the center of the disc) that fits your mill.
All my 4-inch grinders have a metric threaded spindle; their size is an M10 x 1. 5 thread. Ensure you center the disc on the spindle, and clamp the disc snugly in between the inner and outer flanges. The tools supplied with the grinder are required to protect the external flange nut.
If you drop one, you ought to not utilize it. If it split when dropped, there is a danger it will blow up when the angle mill spins it as much as full speed. (Don't think me? Google images for 'angle mill mishaps' if you attempt.) Grinders drive the spindle very quickly, and this speed combined with the abrasive material does the work.
