Amazon.com Product Description
The DELTA GR275 6-inch Variable Speed Grinder with Tool-Less Change incorporates three different wheels for sharpening, grinding, and buffing. It features a 2.5 Amp induction-type motor for powerful performance, and has a variable speed of 2000 to 3450 RPM for a fine level of control depending on the materials you are working with.

Customer Reviews

Poor Quality Control
I purchased this unit and found a couple problems with it. For one, they left a burr on the arbor that caused the left wheel to tilt noticably - not very good at 3500RPM! Also, both wheels were labeled identically, even though they were obviously different grits, and different colors. Needless to say, this unit went back, and my desire for Delta gear has lessened.

I will say that the dual-speed option is very nice. I almost kept it to make it into a buffing station, but figured I could save several dollars by not buying wheels or guards.


On another note, I purchased this to use with a Wolverine sharpening system. None of the current Delta units will work with the Wolverine since the mounting holes do not allow one to center the Wolverine base unit centered directly under the wheel.

Very Satisfied
I ordered this grinder on the 2nd, received it on the 8th with the free super saver shipping option. Along with the lower price, these two factors alone helped make this a very good deal. I am fairly new to woodworking and have accumulated a number of chisels/carving tools that require sharpening before use. Pre-sharpened chisels are nice, but they come at a price that is beyond my limited budget.

Here is the breakdown -

This grinder is advertised specifically for sharpening. The variable speed is an important feature as it limits the possiblity of burnout on the tools. The grinder comes with a white sharpening disc, regular grinding disc and buffing pad. All I need is some buffer compound and I pretty much have everything I need for sharpening on the grinder.

Tool rests provide enough maneuverability to sharpen shorter tools as well as longer chisels without having to make a jig to hold the small tools closer to the disk. Assembly was pretty straight forward, took me about 15 minutes to get it together and running. Nice change of pace for those like me that have purchased much cheaper tools in the past and have had to make sense of mimeograph quality instructions and a slew of nuts and bolts that do not seem to fit properly half the time.

I give it only 4 stars instead of 5 due to the short length of the light (already noted in other reviews) and the fact that the toolrests are not interchangeable. The rest next to the white stone has indentations made for drill bits. Nice feature except for the fact that my small chisels can fall into the gap while grinding. Would have been nice to be able to swap rests instead of swapping grinding disks.

At any rate, the problems encountered were very minor and are mostly related to personal preference rather than faults with the product. I definitely feel I have my money's worth. I could have went with a cheaper grinder, but by the time shipping, purchasing of wheels specific to sharpening, and the annoyances of lack of variable speed (not to mention potential damage to the tools)are all factored in, it is obvious that this was a wise investment.

Best grinder for the price
This is great Delta equipment! Well, there is always exception to the rule.
Grinding stones are really good, and even tool rest is suitable. I use Veritas tool rest on one weal and Delta's on another. What most surprised me is that the grinder does not have arbor run-out. This is really uncharacteristic for Delta. Has Delta been sold out by Black & Decker?
