Box Contains CP9121BR Angle Grinder 5 Inch / 127mm Review: I bought this to replace my Ingersoll Rand 3445 air angle grinder. What's not clear in the descriptions is: Is the red body of the CP9121 plastic or metal? I glad to report IT IS DEFINITELY METAL. Very likely powder-coated aluminum. (Of course I don't want to scratch it and see for sure.) This unit has the rugged build I was looking for. I noticed what looks like this exact same grinder, same color, under different branding and very close to the same price elsewhere, but sorry, I forgot the exact brands. Note: If money is no object you should also be looking at the Ingersoll Rand G2 series grinders, which are supposed to be super industrial duty. Another competing product is the IR 3445. I had the first version of the IR 3445 (the non-MAX version) and it broke within a year. (I use these for removing mill scale from structural steel.) Although I am partial to IR air tools, I will never get a "composite construction" (read metal/plastic) air tool again. One drop and the housing cracked at the aluminum/plastic joint, and IR doesn't sell the plastic replacement part separately. You have to buy a whole new housing which costs $100 minimum. This (the CP9121) seems a little more noisy than the my previous grinder, but heck, I'm always wearing ear muffs anyways. I will gladly trade the slight noise difference for something durable. Review: Works great just keep it oiled. ## Features - 5 Inch / 127mm Angle Wheel Grinder - Keyless adjustable protective guard - Aluminum alloy housing - Helical bevel gear design - The 600 Watt motor gives a high performance ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B004WHFCP0 | | Best Sellers Rank | 313,933 in DIY & Tools ( See Top 100 in DIY & Tools ) 919 in Angle Grinders | | Brand | Chicago Pneumatic | | Colour | Rot/Ausflug, Einfarbig (Getaway Solids) | | Country of Origin | Germany | | Customer Reviews | 3.7 3.7 out of 5 stars (12) | | Global Trade Identification Number | 00015451669300 | | Horsepower | 0.8 | | Item Dimensions L x W x H | 24L x 12.7W centimetres | | Item Type Name | Chicago Pneumatic CP9121BR Angle Grinder 5 Inch / 127mm | | Item Weight | 4.62 Pounds | | Manufacturer | Chicago Pneumatic | | Material | Aluminium | | Maximum Rotational Speed | 12000 RPM | | Model Number | CP9121BR | | Power source | Air Powered | | Style | Chicago Pneumatic CP9121BR Angle Grinder 5 Inch / 127mm | | UPC | 015451669300 | | Unit Count | 1.0 Count | | Wattage | 600 watts | ## Product Details - **Brand:** Chicago Pneumatic - **Material:** Aluminium - **Power source:** Air Powered - **Product dimensions:** 24L x 12.7W centimetres - **Style:** Chicago Pneumatic CP9121BR Angle Grinder 5 Inch / 127mm ## Images ![CP9121BR 5-Inch/127 mm Angle Grinder - Image 1](https://m.media-amazon.com/images/I/61g8EyyOAQL.jpg) ## Available Options This product comes in different **Size, Style** options. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Review *by G***H on 24 April 2014* I bought this to replace my Ingersoll Rand 3445 air angle grinder.
