I have reviewed many(see other reviews) and these bits had some problems. These bits simply rip into the workpiece with a little to much zest for my taste. Good bits are vital to a drills ability to do its thing. These are the standard drill bits most of us are familiar with and use for drilling in metals, woods and plastics. you have been reading my reviews lately, you know I have reviewed drill bits. Good quality, sure. I would recomend these only for rough work where tearout and overall finish didnt matter. If my workpiece hadn't been clamped down, the results may have been disasterous.
They have all the smoothness of a spade bit. I like The "no-spin" shank used on bits sizes 3/16-inch and over, as it eliminated the anoyance of bits spining in the chuck instead of drilling. Alot of drill bits in fact.Spadebits, auger bits, hole saw bits, masonary bits and finally twist bits. You could damage some expensive wood with these bits performing like this. I got 2 sets of these bits on clearance (what else is new) This set includes two 1/16-inch split point bits; 1 each split point bits from 5/64- to 7/64-inch-by-64ths; 2 1/8-inch split point bits; 1 each Pilot Point bit: 9/64, 5/32, 3/16, 7/32, 1/4, 5/16; and 3/8-inch Pilot Point bits in a tough yellow plastic case. In use, I found these bits to be a bit too aggressive due to the pilot point grabbing violently. At 16 dollars and change from amazon, they are reasonable cheap. But way too aggresive for my liking.
These bits are OK for hard woods, but for anything softer (pine, fir, poplar, etc) they tend to screw into the wood rather than boring a hole. The "pilot point" appears to be the major drawback of these bits, IMHO, not the major benefit.
I purchased this drill bit set for use around my house. I would highly recommend this set of drill bits for anyone looking for a set to use around the house (my only knowledge of use). The set includes two of the most popular sizes, 1/16 and 1/8.
The bits appear to be very sturdy and reliable. The case that houses the bits is fantastic. I have a Makita cordless drill that this set works perfectly with.
a well thought out and nice touch. The variety and size of bits is perfect for around the house. 1/16 up to (a large) 3/8.
very sturdy with a good closing/locking system. Good bits, good selection of sizes, good quality, good storage case.
Before buying this Dewalt Cobalt set, I had been using an inherited set of craftsman bits labeled "the best bits we sell", and that was all I knew about them.Preparing to do some metal working, I decided I must have a set of cobalt bits. So no sooner than receiving the set, I just happened to need to drill into a table saw stand of 1/8 inch likely hardened steel.And though it probably shouldn't be done, put the 1/4" bit in my hand drill, pushed up against the leg, pulled the trigger only to have it skate down the side of the work.Problem here is that though this set has a split point, the angle I believe is only 118 degrees, rather than these craftsman at 135, with a pilot point, which in combination works much much better.And and after moving to the press, this has proved to be a significant disadvantage for not just at the start of the cut, but the greater angle and pilot point seems to pull the bit through the material with ease.A much nicer cutting experience.I imagine if your only doing woods, this may not be noticed as much.But for the price when here on sale its hard to resist.If I could have done it again, I would opt for the 14 or 16 pcs sets which have sizes up to 3/8ths.And it should be noted the cobalt makes the bit more hard, but more brittle as well. Should maybe keep cobalt on the drill press, eventually your bound to have an accident using a hand drill.
Good set for working with soft metals with one caveat: upon penetration these bits pull the worked piece towards the drill quite agressively. Otherwise they are very effective, and the extra bits offer that assurance that you won't have to pause a project should you accidentally break one of those sizes.The case is a bit bulky compared to other drill sets, but that's actually a good thing -- it's deep enough and there's enough extra space above the large bits to hold a 1/4" cordless screwdriver/drill chuck adaptor. (YMMV, mine is a Skil #92170)
