OEMTOOLS 25023 Combination Tune-Up Feeler GaugeBrand Great Neck Saw - Pack of 2

I have noticed this on many Amazon items that list different variants on the same page. The reviews and Q/A's are intermixed as well. The reviews for verified purchasers shows the "Size", but the Q/A section does not. I bought the "size" that reads 3-1/4". There are 26 blades from 0.0015" to 0.025". The spacing is 0.0005" until they reach 0.003", and then the spacing becomes 0.001". So I would call this an SAE set, even though it has the mm equivalents marked on them. In my case, I specifically wanted a 0.5mm feeler, and this has 0.508 and 0.483, so I will have to settle with the 0.508 for now. I will be buying the 25 blade "size" next, which has pure mm spacing. Unfortunately, nothing lists those sizes other than the picture showing the thickest at exactly 1.00mm with no SAE equivalent.As far as quality, yes they arrive with some oil on them. It is to protect them from corrosion. If you don't like the oil, feel free to dunk it in water </sarcasm>. The seem like very good quality.Just be very careful with Q/A answers with any product that has different sizes. You might get something different. It's a shame that Amazon doesn't have the vendor change the product details for each size. Especially with an item like this where size is critical.

Really ticked me off when I got this and it wasn't mm increment blades like the picture makes you think. No, you don't get .007mm, .008mm, .009mm like the pictures shows. Those are actually INCHES. I have included some pictures so you can see the whole blade and also the listing on the back of the package for what the actual blades are. Of course none of this information is in the product description. This is totally useless to me as I needed thousandth's of a mm increments, I may as well pitch it in the dumpster. Shame on Amazon and this seller for deceptive description. As for the product itself it has a cheapo bolt and nut and the imprint measurements on each blade are barely readable.

Blade inches: 0.0015, 0.002, 0.0025, 0.003, 0.004, 0.005, 0.006, 0.007, 0.008, 0.009, 0.010, 0.011, 0.012, 0.013, 0.014, 0.015, 0.016, 0.017, 0.018, 0.019, 0.020, 0.021, 0.022, 0.023, 0.024, 0.025. Blades metric: 0.038, 0.051, 0.063, 0.076, 0.102, 0.127, 0.152, 0.178, 0.203, 0.229, 0.254, 0.279, 0.305, 0.330, 0.356 ,0.381, 0.406, 0.432, 0.457, 0.483, 0.508, 0.533, 0.559, 0.584, 0.610, 0.635.Blades are clean, straight, and oily. Blades can be removed. Blades are made to inches, but package lists inches and mm.

These feeler gauges are an insult to machinist across the world - even in India/China, where they are likely produced.So many issues, where do I begin:First, the housing has a cheap feeling and is very thin stamped metal. The feeler gauges themselves are also problematic. For one, the .002" less ground surfaces are surprisingly rough and ground across the direction they will be used, so surface grain would most likely act like a 2000 grit file. I personally wouldn't want to slide them under any rocker arm, for fear of upsetting the lapped surfaces.Additionally, a fair number of the gauges have detectible burrs risen on their leading edges (no doubt from being stamped out of sheet metal, I guess). So not only is the ground -.002" area rough, but there is a burr on the forward edge (easily detectible with your finger nail) which would clearly need to be stoned off on a fair number of the gauges.As if this wasn't enough, the laser etching is just comically poor. Many of the gauges had such faint etching, that you couldn't even really see what the numbers were without using a flash light.Even at less than 1/2 the Amazon price around town locally, these are still just over priced junk. I would suggest avoiding this particular tool and looking for another brand.

Impossible for me to say if the measurements are fully accurate, I guess, but this is an inexpensive tool that absolutely gets the job done. Bought it for measuring the string action (height) on guitar and bass necks and making adjustments. There’s really no more accurate way I can come up with to do this visually. The blades do have a oil/lubricant coating that’s a little annoying when you first start using it, but I assume that’s a necessity to be able to separate them.

no complaints here, great price. i use this for gutiar setups... new little trick I learned is, whatever gauge your high string E is, that is the relief you should get at low E 7th fret with capo at 1st fret and holding down where neck meets body (usually 17th'ish fret).so if you have a .009 guage up top, aim for a .009 relief in that area. good set of tools here.

After years of adjusting nozzle heights on my 3D printers using a piece of paper, I decided to get serious and use a feeler gauge. While I've settled on a 0.005" gauge as my choice, I couldn't handle spending more money for a set that had fewer gauges that are likely of equal quality of the gauges in this set. So I bought this.Most of the time, this set just sits out with the 0.005" gauge out and ready for when I need it. Recently though, I helped my father with some engine and transmission work on his 1968 Z/28 Camaro, and due to some components being replaced, specifically the engine flywheel, we had to reposition the engine's starter motor via shimming. These gauges were very helpful in determining that there was correct clearance between the flywheel teeth and the motor pinion.So while I usually don't need the variety of gauges in this set, I'm definitely glad I had this set on hand when I helped work on that car.
