When you're using grinders regularly it can be tedious changing accessories all the time. When these red Milwaukee grinders were on sale, I bought 2. I can set up a cutting disk in one grinder and a grinding wheel or a sanding disk in another one. This accelerate my workflow.
This was terrific for big heavy tasks like concrete and approximately cutting up big steel areas. There is no 'finesse' with a 9-inch mill, so it's not ideal for bike work (what size angle grinder to cut paving slabs). Don't lose your money unless you have other requirements for it. Bigger is not better in this case. A long time later on, I bought this 5-inch angle grinder.
This is a common size used on older motorbikes, together with 3/4 and 7/8, or 19mm and 22mm for the metric world. If you're cutting this tubing using a 4-inch mill, you may just get three-quarters of the way through and after that you need to reverse and cut from the opposite.
The accessories are a little bit more pricey, undoubtedly, but they do last a longer than the 4-inch ones. I generally leave a cutting disc in my 5-inch mill and leave the 4-inch grinders for other tasks. Purchase a low-cost 4-inch grinder first. If you pick to acquire a 2nd mill, consider a 5-inch grinder if cutting tube is a common job.
This specific grinder's set up with the cutting wheel, or a cutting blade. The one-millimeters are my favorite: They enable you to cut through tube easily, quickly and with a thin 'kerf' (which is the density of the cut). Bosch makes these specific ones, and I simply buy another box of 10 when they're on sale at my local hardware shop.
The other accessory that I find really beneficial is a 'flap disk' or a sanding disk. A flap disk is an array of sanding pads bonded to a backing plate, available in a series of abrasive grits. As they are utilized, the edge of the pad wears away to expose more abrasive.
Again, this specific one's Bosch, however just since it's the brand my regional shop stocks. They aren't cheapin Australia they cost around about $7 to $8 each, but they do last a long time. And they are really beneficial when dealing with a bike. I prefer to acquire 100 grit or 120 grit.
One of my 4-inch mills is always established with a flap disc. I don't typically utilize grinding disks on bike jobs. Similar to the coarse grit flap wheels, I think a grinding disc is a really aggressive technique of eliminating metal. how to change an angle grinder disc. I tend to pick a finer-grit flap disk prior to I would use a grinding disk.
On my old Makita grinder, I have actually completely set up a wire wheel. This is among my go-to tools for removing paint or cleaning rust off surfaces. As the wire bristles spin, they smash paint and rust off a steel surface without substantial damage. Steel bristles are harder than aluminum, so they will harm an aluminum surface area.
This grinder is used specifically with a wire wheel (how to remove angle grinder disc). Because the wire wheel is much heavier than a cutting disc, it puts a more load on the electrical motor and will probably accelerate the grinder's ultimate death! Along with the wire wheel, my other preferred paint-removal device is the paint-stripping disc.
The ones I buy locally are explained as 'silicon fertilized abrasive nylon.' These are great for motorbike work, specifically for larger, flatter surface areas, such as fenders and gas tanks. With an angle grinder, a paint removing disc and a wire wheel, you can get rid of paint from a whole motorbike. Would it be quicker to send it for sand blasting or dipping? Sure, but you can do it in the house at low-cost with these tools (what type of blade to cut concrete with an angle grinder).
I have stripped a number of tanks and fenders with these wheels, and in my non-scientific tests, I discover the 5-inch variation lasts a lot longer than the 4-inch version. This would recommend its more cost-effective to purchase these in 5-inch if you have a 5-inch mill. Similar in building to a flap wheel, artificial non-woven flap discs consist of a polymer abrasive instead of an abrasive particle pad - what size angle grinder to cut paving slabs. how to cut concrete pavers with angle grinder.
They are much less aggressive than a sanding flap disc, so they're fairly safe to utilize on aluminum surface areas. I've been try out sanding disks which require backing plate. I was wondering whether it would be more affordable to utilize something like this than to pay for a sanding flap disk - what size angle grinder to cut paving slabs.
You seem to get much more material eliminated with a flap disc. I think this is due to the flap disc exposing new abrasive as it wears. When these sanding discs are worn, they enter the trash. It was simply an experiment to see what would happen. Stick with flap wheels if you can.
There's undoubtedly a huge potential for mishaps with grinders. However if you take a couple of basic preventative measures, you can minimize 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 grinder.
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 secure the disc snugly in between the inner and external flanges. The tools provided with the mill are required to secure the outer flange nut.
If you drop one, you must not use it. If it cracked when dropped, there is a danger it will take off when the angle mill spins it as much as complete speed. (Do not think me? Google images for 'angle mill accidents' if you attempt.) Mills drive the spindle really quickly, and this speed combined with the abrasive product does the work.
