I just purchased the Delta 23-735 10" industrial grinder after looking at other options such as Baldor or Dayton. While the quality of the grinder is not in the same class as either of the aforementioned units, neither is the price. A 10" Baldor or similar with the pedestal would run at least $200 more.

The grinder arrived in two boxes, each adequately packaged to prevent damage. With the heaviest box weighing in at 115 pounds, some damage to the packaging was expected, and sure enough found. The grinder was undamaged.

Assembly of the unit was straightforward, and all parts required were included with the exception of an Allen wrench for tightening the pedestal post to the base. While these were factory installed, they were not tight enough to prevent the post from turning in the base once the grinder had been installed. Also, the holes in the flanged post base were not centered, and in order to mount the flanged post base on the square baseplate, some minor filing of one of the bolt heads was required.

Upon initial startup, the grinder exhibited some vibration. Close examination seems to indicated a small imbalance due to non-symetrical grinding wheels, but facing of the wheels should cure this. Power of the unit is adequate, and motor noise is much lower than expected. Coast down time after the grinder is switched of is quite long. The heft of the unit does a nice job of minimizing vibration.

The flexible lamp does not include a light bulb, but does seem to be constructed fairly well.

All in all, the unit appears to be solidly made, and should be more than adequate for most users looking for a heavy duty 10" grinder.

Excellent professional grade grinder

I've had the Delta 23-735 10" industrial grinder for a couple of years as of this writing. If you already own a grinder, consider retrofitting your old machine with wire or buffing wheels. Overheating metal parts was a serious issue on my previous 3450-RPM grinder, but is less so on this 1725 RPM machine - that alone made this a worthwhile investment. The 23-735 is big and heavy; 125 pounds; 15 1/4" wheel center to center; and 11" tall at the motor housing. All that cast iron in the motor frame and tool supports keeps vibration well within the acceptable range, and gives the tool a look of quality and heft. The toggle switch is protected, so it's unlikely you'll accidentally turn it on, a good safety feature. I prefer a can of water for a quenching tray as it's quicker to fill and empty, but the built-in water tray is amply sized. The fitted lamp is nice, but the goose-neck section should be a few inches longer. At the rear of each wheel's housing is a 2.5" dust port. I usually keep a rubber-banded sock on each port; but attach a vacuum on dusty jobs.

Since I'm tall, the grinder is mounted on a 39" high bench. I used the very sturdy 33" high cast iron pedestal that comes with the grinder for another shop tool. I only use the Delta grinder a few times a week, so buying a Baldor 10" grinder (triple the cost), couldn't be justified. The Baldor was also much too wide for the available space.

The Sears Craftsman 10" professional grinder (model #21160) costs about the same as this unit from Amazon.com, but it doesn't include that nifty pedestal. (I'd give no credence to Sear's claim of 1 HP versus Delta's stated 3/4 HP, since the machines are virtually identical. Delta's is plenty powerful, and they probably make the Sears machine anyway.)

In summary, if you use a grinder for hours every day or need the wheels to be really far apart, get the Baldor. For everyone else, the Delta is a professional grade grinding machine.
