230 Pieces Titanium Twist Drill Bit Set, 135° Tip High Speed Steel, Size from 3/64" up to 1/2", Ideal Drilling in Wood/Cast Iron/Aluminum Alloy/Plastic/Fiberglass, with Hard Storage

Great Value, Really nice case, Lifetime supply of bits!!I used to pay $10 per bit... and this thing is a Lifetim esupply for only $40!

They break when I press too hard and shatter. Lucky there are plenty, and I am trying to be careful when drilling. Average sharpness. I have used better bits, but they cost over $10.00 each. Good for most projects. Recommend a better bit for important metal drilling. Once a bit breaks in a metal hole, you are done. I couldn't drill it out with even an expensive bit.

Just what I was looking for to replace all the broken bits in multiple drill sets. I like the clear plastic organizing case they come in and the titanium finish matches the drills in my DeWALT,Master Mechanic and other genetic drill sets. You may think 276pc set is a little overkill but I broke 4 bits on my last project and that’s what prompted me to buy this set (along with the good price). I gave a rating of 4 stars for a couple of reasons. 1 the size of the bit is stamped right where the chuck bites the bit causing unreadability after multiple uses. 2 I haven’t used them enough on various materials to fully evacuate them. I noticed a little dancing on one project drilling into 1/8” metal tubing but I think it was due to a cheap chuck on my drill press because it was fine after the bit—-bit.

Sharp drill bits for a good price. Great for replacing the smaller bits in a set when they break.

Not the best drill bits. But it gives me variety for the small jobs I do around the house.

Should have a better way to secure bits in the case. Mine fell over when I opened it and I spent the next 3 hours putting them back in the proper place.

cost was great, bits look good fast delivery

Quality drill bits and a wide selection in this kit. I can recommend it, especially for the value it represents.
