Best of all, users can remain in one battery platform, using the same fast-charging 18V batteries on the XAG12Z1 as they use across the Makita 18V LXT® cordless tool system. It’s part of Makita’s expanding 18V Lithium-Ion system, the world’s largest cordless tool system powered by 18V Lithium-Ion slide-style batteries. For increased versatility, the tool can also be powered by Makita 18V LXT® and Compact Lithium-Ion batteries with the star symbol on the battery indicating Star Protection inside.
Since we have no projects with metal cutting or grinding lined up, we decided to grab a quick piece of angle iron, fasten it to our workbench with clamps, and see how the Makita would handle one of the more common, and relatively tough, uses for this tool: cutting straight through the angle iron and smoothing out the cut edge. There’s a rotation lock on the top of the tool, and Makita includes a hefty disc-change tool that works really well at loosening the set nut for the disc. The primary advantage of this tool is the performance of a corded angle grinder without the need to drag a cord around with you.
The Makita 18V X2 Brushless Angle Grinder also comes with some safety and efficiency features worth checking out. The other interesting thing about the new Makita 18V X2 Brushless Angle Grinder is the vibration control. Makita 18V X2 Brushless Angle Grinder FeaturesElectric brake stops the grinding or cut-off wheel in 4.5 seconds or less for maximum productivity.
3500 rpm angle grinder Related Question:
What is good rpm for a grinder?
The speed should be between 850 and 1,600 RPM. If you are cutting stainless steel and tool steel, with a 4-inch disc, the speed should be between 3,500 and 6,000 RPM. If you are using a 7-inch disc, the speed should be between 1,900 and 3,200 RPM.
What rpm does an angle grinder spin at?
Unlike drill motors that run at about 700 to 1,200 rpm, grinders spin at a breakneck speed of 10,000 to 11,000 rpm. They’re fast enough to be scary!
Is higher rpm better for angle grinder?
Boyd said, “Working at the highest RPM, even if it is a variable speed machine, may give you the fastest removal rate for grinding. But depending on the tool or abrasive, the abrasive could wear more quickly, and you might not get the overall productivity.
What rpm does a 7 inch grinder turn?
DEWALT Angle Grinder, 7-Inch, 8,500 RPM, 4.0-HP (DWE4517) , Yellow – Power Angle Grinders – Amazon.com.
Is a variable speed angle grinder necessary?
Variable speed will be used if you want to use the angle grinder as a polisher/buffer, as those wheels wont work as well at 10,000rpm.
How many decibels does a grinder make?
Linishers and bench-mounted grinders can produce noise levels of about 88 to 95 dB(A). Hand-held angle grinders can produce noise levels of about 90 to 115 dB(A).
What is the most common angle grinder size?
The most commonly used sizes are the 4” and 4 ½”. These grinders typically have the capacity for wheel diameters of up to 7”, with particularly small versions having the capacity for 3” discs.
How deep can a 125mm angle grinder cut?
All in all, 125mm angle grinders are extremely versatile tools despite their limited cutting depth of just 38 mm. While 115mm angle grinders offer a maximum cutting depth of only 30 mm, they are precise, easy to handle and lighter than larger versions.
Can I use bigger disc on angle grinder?
Fitting a 14 inch (356 mm) cut-off disc to a 9 inch (230 mm) angle grinder will increase the edge speed excessively to at least 120 m/s (430 kmph). The photograph below shows an angle grinder with the wrong size cutting disc fitted and the guard removed.
How many watts is a good angle grinder?
for grinding: 1,000 watts. for cutting through simple materials: 1,500 watts. for cutting through strong metals: 2,500 watts.
How important is amps in an angle grinder?
Amps indicate the power that the motor draws during use and generally indicates the size and power of the motor (higher is “better”). I personally think a well built tool with the features I want and which is comfortable for me to hold and use is more important than the amp rating.
How is rpm calculated on a grinding wheel?
If you want to maintain exactly the same chip load, the equation is: new rpm = original rpm × (original diameter ÷ current diameter)1.5. So, if you were running your new 18″ wheel at 1,800 rpm, run it at 2,366 rpm [1,800 × (18 ÷ 15)1.5] once it gets down to 15″—again, within the safe speed.
What direction should you feed the cutting disc into the workpiece?
The direction of the cutting motion is important. Always feed the cutting disc into the work so that it cuts in an upward direction.
Is the DeWALT grinder variable speed?
The DeWALT DCG412M2 125mm XR Premium Angle Grinder has a powerful fan cooled motor and intelligent variable speed trigger.
What does no load speed mean on an angle grinder?
The speed of an angle grinder determines the quality of the cutting or grinding action. This is measured by no-load speeds, which means ‘how fast the disc will rotate before it makes contact with the work piece’.
