User questions & answers

Question:	Required CFM
Answer:	It’ll average about 3 cfm. It’s happiest between 5-7. Great tool. Mine seem to last forever. I use them in the shop on the shop compressor and in my service trucks at a lower cfm. No problem with either setup, just be sure and keep your tools properly lubricated, and free of “wet” air.
Question:	How do I grease this grinder? I don't see a fitting for a grease gun
Answer:	As an air tool it gets greased with air tool oil added to the air inlet
Question:	Is this small enough to fit inside of a 3" pipe
Answer:	The die grinder itself is. I don't know what kind of attachment you have.
Question:	What is the RPM? Can you vary the speed
Answer:	27,000 rpm wide open. Yes, you can vary the speed with the trigger. I definitely recommend this die grinder it's very smooth and powerful!

User questions & answers

Question:	How do you know how much grease to put in the head or what kind or the needle size
Answer:	There are small pump grease guns specifically for air tools. They are available through Ingersol Rand, and other companies. The grease for this particular line of IR tools should be from IR. It’s safe to put in about three good shots of grease. Don’t overdo it. Seal damage can occur and reduce the life of the tool.
Question:	Cfm requirements?? Anyone
Answer:	3 cfm to operate, 18 cfm draw over long pulls.
Question:	Ingersoll and rand suppose to be the best of the best.. Are these just cheap knockoffs or these real deal
Answer:	No they are not knockoffs, its the real deal. I went through a few cheap ones that didn`t last. This grinder is rock solid and I can see it lasting me forever. Highly recommend!
Question:	How do you put grease in the grease port
Answer:	Where the tool transitions 90 degrees, there is a little raised ball on the one side...it's spring loaded. You need a pointed grease adapter, a needle but not the hypodermic needle...a chainsaw grease gun works well. Oil through the air port never gets to the 90 degree portion of the tool.

Question:	Hello. i have 2.0 hp compressor, 4.6 gallon, 6.40 cfm @ 40 psi, 5.30 cfm @ 90 psi. i need that tool to clean rust from brass. do you think that is ok
Answer:	Whether your brass was fitted to black iron and the rust built up that way, you have lime/scale/mineral build up, or heavy oxidation you should be able to remove it using this grinder and your compressor combo. Your compressor is on the small side and will run nonstop. The tool will also be underpowered compared to running it on a larger compressor but with the proper choice in abrasive or bit you should be able to get the job done. Depending on how heavy the build up is and how important a fine finish is on the brass, you may need several different abrasives. The short answer is yes, this gun and your compressor are less than ideal matches, but you should be able to work with them.

User questions & answers

Question:	where is this made
Answer:	Product information for the CP875: Pneumatic tool equipped with 1/4" collet chuck for use with various burrs for grinding - No other use permitted. For professional use only. General maintenance applications Compact and lightweight tool designed for easy maneuverability Ideal for limited space applications 1/4" and 6 mm collets 90° angle head allows flexibility in tight areas Built-in air regulator
Question:	How much cfm does this die grinder consume? my compressor will put out 2.6 cfm at 90 psi, will this be enough
Answer:	This tool requires 22 SCFM @ Load. In other words, to run this tool continuously, non-stop, you would need a compressor pump capable of running 22cfm @ 90psi. In reality, As long as you have a large enough tank, you will be able to run this tool with no problem for several minutes continuously. Very few home shop users will have a compressor this large. I run this on a 5hp 60 gallon single stage with no problem.
Question:	What is the warranty coverage on this die grinder? Is there extended coverage available
Answer:	Weird. I just checked my toolbox and my 90 degree cp875 is red with no black logo. I checked my purchase history and it shows a black logo. Must be something new they are doing to the 90 degree models. However, the straight grinder pictured has no black logo.
Question:	What is the warranty coverage on this die grinder
Answer:	the exhaust is out the front
