Question: Is the !/2 drill shank cut down enough to fit a 3/8 chuck.
Document: This have a brad point and the 1/2&#34; bit is reduced to fit 3/8 drill. Bits slide in securely and do not fall out. Even the small bits do excellent work with out snapping
Great drill set! This is my second set in about 3 years...only because I wanted a second set to travel with me in my truck. Some of the smaller sizes have multiples, which is a great idea since those are the most used ones. The 1/2 inch has a tapered down shaft...so it fits my 3/8 inch drill. Very pleased with these.
I thought that these would be good drills as they were DeWALT. Wrong. Don't bother wasting your money if you actually need to drill with these. Was drilling thru plain old 11ga steel and the 5/16 bit broke on the first hole. Then the 3/8 bit broke off one of the cutting teeth on the second hole. The 1/2 bit was missing both tips after only 4 holes. I can't imagine how the smaller bits will hold up.
The first time I drilled cast iron, it was like going through butter. Generally, these bits are great - until the coating wears off. One bit (1/8) I cut 1/2 aluminum plate by drilling holes every 3mm - and after 100 or so holes, the coating started to wear off (was using beeswax for lube). Of course that is a lot to expect from a bit and I am sure with better lubrication this would not have happened.
I wanted a set that went all the way up to 1/2&#34; but would also have most of the intermediate sizes in 1/64 increments. This fit the bill and I noticed a huge improvement in performance over my old dull drill bits.
The design of these bits is very poor. When drilling in wood, the chips are not drawn out of the hole and instead bind and burn on the bit. You need to constantly pull the bit to clear the chips, so it takes 2-3 times longer to drill a hole. I do like the the center point.
I ordered this set mainly because of the Hex shaft feature. However, hex shafts are only found on 3/16&#34; bits and larger.There are other extra nice features, however:1. Each bit is mounted in the case by tilting and inserting the shaft into a hole, then clicking it down into place, very secure fixation.2.
The product came exactly the way it was advertised and works great! The bits fit perfectly into the drill and it's very easy to use.
Put it in his stocking for Christmas. Said he needed some new drill bits. Got a titanium hip last January so figured if it was strong enough for me, these would be great for him! He seemed happy.
I have been drilling on metal for several months and used like 3 or 4 different brands of drill bits.
