Hex Bit Set Metric 9PC With Rail - Allen Wrench Bit Set 1.5mm - 8mm - Perfect for Automotive, Bike, Bicycle, Appliance Repair - Ram Pro

My set got delayed by the last Arctic cold blast. Originally supposed to arrive last Thursday, now scheduled to arrive this coming Thursday. I didn't look closely at the product zoom, and it doesn't inspire confidence in the quality of the product. Some bits look sharply ground, others don't - AND THE 4 mm BIT IS TOTALLY ROUNDED in the provided picture!! When they arrive, I'm going to inspect them closely, and measure with a micrometer. Small bit size accuracy and precision is more critical than with larger bit size. I ordered a few different sets from different makers - to keep with different vehicles and in two tool boxes. I'd sort which goes where by quality. This set had the least complaints here on Amazon about quality (except Wera) when I placed my order. We'll see what we get in a week or so.Update:The product actually arrived just a few hours after I wrote the above. It is not what is shown, but the bits are there and look better than the advertisement picture. The holder is blank, with no labeling. The package says nothing about "Ram Pro." The packaging is an American product from Prosperity Tools of Florida with a "Limited Warranty" to be free from defects, and "Manufactured in Taiwan."The 1.5, 2.0 and 2.5 mm bits measured very close to their labeled size. The 3,4 and 5 mm bits measured at or very slightly (<5%) larger than the labeled size. The 6 and 8 mm bits were very close to 6 and 8 mm respectively.I haven't used them yet, but I am not initially disappointed except the lack of labeling on the holder - which at this price point is not a deal breaker. A permanent marker can take care of that omission. So, unless they fail in service, they get an extra star. Your actual delivered product may be different, though.

I love the bits, they work exactly as wanted. And prefer the red plastic holder, it is very easier to locate on my work table.But...see the white numbers just below each bit on the red holder? They are not on the product shipped. These labels were one of the reasons I purchased this set.I am a bike fitter. Almost all bolts are either 4, 5 or 6mm. This set has a 5.5mm bit, I have never seen a 5.5 bolt on any bicycle. So, it is necessary to have the labels, to prevent me from picking up the wrong bit. I had to create labels using my printer, and tape them onto the red holder.They look cheap, but are functional.The product would have been perfect, if it arrived as represented.

These bits seem a bit less durable and/or a less precise fit compared to another set of hex bits I bought several years ago (not sure of the brand). But they’re still very useful to have around for working on a bike. For that purpose, it’s occasionally nice to have 2.5mm included in the set.

This is not a product review, per se, on performance. I’m sending a pic of what was received because in reading the reviews many said the bits did not come in a labeled plastic holder. Mine did.Will update review later after using product.

For some reason, none of my 3+ electric screwdriver sets have a decent assortment of metric hex bits. I've already used these bits to assemble a table and to repair a 3D printer. Very useful!

Good quality and value this set includes the most common sizes that I use. I prefer these 1/4 inch drive bits to the angled hex wrenches. They give me much more precise control.

much easier swapping out bits as opposed to using a bunch of tiny Allen wrenches. The included holder works great for keeping them organized, it is soft and easy to remove.

These work. Not your highly polished top brand tool, but fine for work on all requirements. Because these are not chromed, keep them dry.
