VESSEL IMPACT BALL™ Torsion Bit 30+1 PC. Set in SLIDE CASE No.IB31P02U Made in Japan by VESSEL

I'm a little picky when it comes to bits. I work in HVAC service and start up, and I find that I need to have a complete set of the most common fastener drivers for use with bit ratchets, bitholding screwdrivers, torque tools, and impact driver adapters.Thing is, most big box store tool brands don't offer a complete set, are of questionable quality, come in oversized cases, and inundate you with PH2s and TX25s.German brands offer better selection and better quality, but ars typically similarly oriented towards power tool usage/repeated ph&tx fastener installation, and it's difficult to find a set that includes BOTH metric AND imperial hex sizes.For a while I had been building my own kits using wera's cloth bit organizers and PB swiss bits that I purchased individually. But...that too was less than ideal, as the cloth bit organizer held onto moisture more than I'd like, and the bits had a tendency of falling out and getting lost in the bottom of my veto tech pac.This hits all the right checkboxes. Long and compact organizer that's great for tool bag use, quality bits, a little longer than traditional 25mm bits (which is GREAT for motor starters that tend to use recessed PHZ or PH screws - a typical bit in a holder has a hard time reaching those).All that, and the price is right.Now...could it be better? Sure. The bit holder included is...meh. Not magnetic, uses a retaining ring, doesn't solidly engage. And...honestly...I've been a little spoiled recently with the completely rust-free performance of wera's inox bits, as well as the rock-solid durability of PB swiss bits. But that's not enough for me to dock any stars, because finally I found a great set that is geared towards a MECHANIC and won't break the bank.A+ for the folks behind vessel.

Well made driver bit set. Fantastic quality with excellent fit and finish. Highly recommend.

Vessel makes high quality bits. I've gone through many Torx bits with them stripping out pretty quickly until I bought Vessel brand Torx bits. I haven't had a Vessel bit strip out yet.This is a high quality set, with a nice sturdy feeling case. The case slides apart slightly giving better access to the 2 levels of bits. You can only push the bit extender out while the levels are split apart. The bit extender is not magnetic. The bits are very weakly magnetized, if you want them magnetized before usage I'd recommend using a bit magnetizer to make the field stronger. As-is, the magnetic field on the bits is insufficient to hold a screw to the bit.I do wish they had this set available with the longer 50 mm bits so I can attach my Vessel magnetizer to the bits. The Vessel magnetizer slid over the bit is a much better option then a comparably weaker magnetized bit in my opinion. It is for this reason alone that I'm likely to buy more Vessel bits apart from this kit.Update: While this set is not advertised JIS compatible, it appears to be a perfect fit. As I was checking on it's compatibility, I ran across information stating the old JIS standard was replaced with an ISO standard. Whether this is true, I am unsure. The JIS standard for screws has been changed in 1997, 2013 and 2018. Another source says the 2018 standard aligns with ISO 3408-4 and 3408-5 for axial rigidity and static and dynamic load ratings. I presume the differences may be negligible or you may run into issues based upon the age of the fastener and driver. I could not find any compatibility information beyond that. I did run across some advertisements stating Vessel tools were designed to work with both JIS and Phillips screws. A US Vessel distributor does list this product as JIS compatible on it's website.I found the easiest way to check was to try the bits in a dimpled JIS screw. The #2 bit holds the screw snugly and will hold onto the screw horizontally. There is virtually no play in the screw head. My DeWalt bits perform much the same however with a little bit of play. My generic Philips bits also hold the screw horizontally however twist out of the screw with a good amount of play.

This kit contains every bit type I have ever needed except for micro fasteners. The bit holder is useless as it is too long and doesn’t adequately hold bits. The bit holding capacity is just sloppy. The Wiha CentroFix is the best bit holder I have ever used - it holds all the bits available in this kit perfectly. Unfortunately, the Wiha CentroFix doesn’t fit in the slot in the carrying case. Wiha also sells a CentroFix bit holder with very comfortable grip. I keep this kit and the Wiha CentroFix bit with handle in a small zippered nylon bag.

These are worth every dollar

These are great, high quality, well organized tool for my grab and go bag the follows my impact. They hold up great, are very precise, and the case is great. I usually have a set of Wera or Wiha bits, but Vessel has been replacing a lot. I'd say Vessel is at least equal in quality at a fraction of the cost.
