Takes error-prone calculations out of the process of miter cuts to ensure perfect miter joints every time! Easy-to-use tool has two scales: red scale and arrow show the angle for a miter joint, while the black arrow and scale provide the angle to fit a single workpiece to an angle. Simply set your miter saw to the angle that you read. Upside down or backwards, the reading is always correct. Durable aluminum with Teflon™ O-ring for smooth and positive operation.

Wish I bought one of these 20 years ago
It makes figuring miter cuts on trim less of a guessing game. I originally ordered the poly version of this from Rockler, but the markings for the angles were offset making it useless. I returned it to my Rockler store without a problem and purchased the aluminum from the store.

I'm building an oak TV cabinet...
I'm building an oak TV cabinet with multiple angles both in the cabinet and trim, after reviewing the most recent catalog I decided to order this tool which I received today. It's perfect for this project with it's 2 1/2 inch dia. dial it is very easy to read. I continue to be very pleased with the products provided by Rockler.

Great tool to determine wall angles....
Great tool to determine wall angles. It made cutting my crown a breeze. It takes the guesswork out of figuring angles for my miter saw.

Starrett protractor
Protractor is accurate and easy to use due to the scale read out showing the split of angle which expedites the use of this protractor

I think this is a quality...
I think this is a quality tool that has been useful and accurate. While the single cut scale is in 2 degree graduations, the miter red scale is in 1 degree graduations. Tool feels solid, and has smooth action. For super precision work, you may want to use a digital angle finder that has a resolution of a tenth of a degree, but for molding this works great.

I purchased this product for woodworking...
I purchased this product for woodworking mainly because I thought the Starrett name, and the cost, insured accuracy. I am a toolmaker with over 30 years experience, so I understand angles and tools that measure them. I may be a bit demanding, but I think I'm reasonable, given the price. The first thing I noticed when I measured an angle was that the miter cut reading was not exactly half of the single cut reading, and is consistently off by about a half a degree. If I measure a wall corner angle of exactly 45 degrees, the miter cut pointer indicates 22 degrees, not 22.5 degrees, which would be correct. I tested the protractor with precision angle blocks and found the single cut reading to have an error of about a quarter of a degree, so even that reading isn't accurate. Also, graduations are in two-degree increments, so it's up to you to interprete odd degrees and portions of a degree between the lines. All this may be OK for some people, and if I'd paid only $15 dollars for it, I'd not be so disappointed, but for what I paid for it, it does not meet my expectations. I'm returning it tomorrow.

Are the markings engraved or is it a sticker?
Jason P on Apr 15, 2017
BEST ANSWER: They are engraved. Spend the extra money for the aluminum version. I originally purchased the plastic one and the markings were offset making the tool useless.
