Bondhus 11036 Set of 12 Balldriver Insert Bits, sizes 5/64-1/2-Inch

Looks like good quality steel, wish had rust protection (why I giving only 4 stars), keep oiled and should do the job for long time. Product is as advertised, Great Value!

I work in a "job-shop" that manufactures parts for various companies. I am a horizontal boring bar machinist (Devlieg). There are times we will machine and assemble fixtures for our customers and in allot of cases it is a tight fit to be able to tighten the fasteners with a standard hex driver that is in the normal socket drive, and a regular "L" shape allen wrench takes a long time to get the bolt down. I bought this set and used my chapman driver and it made life allot easier. After I snug the fastener down with these inserts I then put the insert in a 1/4" socket and use the torque wrench to set the screw. I made a holder for both the SAE and metric in a block of aluminum. I highly recommend these inserts if you need to work in tight areas, I would not drive the smaller inserts with an drill, stripping or ball end removal may occur.

Should have replacement bits sold separately as well

LIFE SAVER!!! i have one machine at work with three 3/8" bolts holding the base anvil on a flywheel press, and there's only about an inch and a half of working space height to get those bolts out and change it 3 times a day... these fit PERFECTLY in there, in conjunction with a mini 1/4" hex drive ratchet i had floating in my tool chest. it now takes me 15 minutes to do what used to be an hour job with a cut down 5/16" allen wrench.THANK YOU FOR THIS PRODUCT FOR EXISTING!

EDIT - 4/14/2016 - As another reviewer stated, the ball on the 7/64 bit broke off on first use. I've decreased my rating by one star as a result. The regular "L" shaped Bondhaus wrenches are not nearly as fragile as these bits.One normally expects to get a length of hex that is the same size as the ball size, tapering out to the 1/4" drive hex. That is not the case. The 1/4" hex tapers directly to the ball. If and when one snaps the ball off, you have nothing.At first, I did not understand the reviews which complained of this. The seller should really include a photograph of a bit size which is smaller than 1/4".I honestly think I would not have purchased these had I known there was no hex length matching the ball.I like Bondhaus ball drive allen keys. I've broken a few of the small ones over the years, but I've always been left with a basic allen key (sans ball portion).I'm disappointed with these.

I have had them for about a year now very durable. They come in handy cause I came use them with my flexible shafts to access my work. I still use (if possible) regular allen wrenches to start my project (if bolts/ nuts are really tight) and then switch to my balldriver insert bits. I like the fact that I can change out the bits easily from my apex or socket. Overall I feel better quality than Harbor Freight would offer, and I would recommend this product to my friends.

Like them. bad design on the small ones with just the very end being that size. No depth. I don't need depth for what i'm using them for. Just fyi

These are great for the hard to reach angles, haven't had any issues with them at all, and i use them just about everyday.
