Reply:There should be plenty of average quality bits for under $100,I have heard the cobalt bit set from HF is not bad at all.If you want your bits to last a long time,I suggest you use them in a drill press(if possible) with stock well clamped, and definitely use a good quality lubricant like Walter coolcut. I hate to use my good quality cobalt bits in a cordless drill,they are so brittle they break in no time, then I end up with an incomplete set.

Reply:If your using them in a keyless Chuck , I would use mechanics length with the 3 flats . I like the Viking brand. My lws ( Mississippi Welders supply) has them for 80$ right now. Maybe check Weldfabulous, since they are the online sales of mws.
Reply:Drillco brand drill bits are by far the best bits I've had. I have drill thousands of holes insteel ranging from an eighth of an inch to half an inch. What steel thicknesses ranging from an eighth of an inch to 3 inches thick. As long as you keep them oiled and don't go too fast they last twice as long as the Fastenal brand.

Reply:I spent years as a toolmaker then some more years as a CNC programmer and for home use and I believe professional use you can't beat the 115 piece Cobalt set from Harbor freight for price and durability, IMO. I've had mine for a year and used them many times and they've never disappointed me. 😃They come on sale for $90 regularly.http://m.harborfreight.com/115-pc-co...set-61886.htmlGood luck!MikeSent from my XT1254 using Tapatalk

Reply:I purchased the HF cobalt 115 piece set about 3 years ago. Outstanding quality for the price. I've drilled hundreds of holes with them and still going strong. Used for 304,1018,4130,cast,brass,bronze and 6061.Norseman quality bits:http://www.harryepstein.com/index.ph...ct_detail=2604
Reply:I'm not here to recommend any particular set of bits, but to advise you to stay away from the hype of all the crazy alloy and coating marketing BS.... I usually recommend nothing more than good bright HSS bits, but do agree a cobalt alloy bit is nice, if from a quality manufacturer. Forget coatings, they're worth nothing unless you're in the business of repetitive high-speed drilling like in some sort of production environment.

Reply:Just my two cents...sorry for bumping...I drill thousands of holes annually in most metals and some plastics. Yes, I do "keep score" regarding how many hundreds of inches of material a certain drill bit can penetrate. My shop machines everything from plastics to steel that is nearly 60 Rockwell C.Sharpen drill bits? I only sharpen drill bits that are larger than diameter 0-1/2". Used correctly many bits have "collapsed" flute edges by the time their point is worn to the need for sharpening and will have a problematic performance after sharpening. In essence; they are not worth grindng.In an emergency I will use a drill point gauge and grind one by hand. That is a skill that is all but lost I guess and even I am not a fan of it. As soon as a replacement is available that bit will hit the scrap can.None of the "home shop" drill bit grinders I have seen will make a correct point on a drill bit. Drill bit grinding is every bit as serious as the grinding of other cutters and requires specialized machinery that one does not purchase for a few hundred dollars.So, even though there are at least three (03) established and common point angles and web and helix types and materials from that drill bits are made; what would I recommend to someone who wants to drill everything from soft materials all the way through steel hardened into the high 40's Rockwell C?Very simply this: Select drill bits made from M42 Cobalt like this types https://mechanicguides.com/best-cobalt-drill-bit-sets/ alloy high-speed steel with a heavy web and a 135-degree split point or "crankshaft grind" as the old fellows call it. Purchase such tools only from American or a select few European makers.TiN (Titanium nitride) coating? Only if you do as I do and expect a drill bit to produce a few hundred to a few thousand holes. Otherwise you might as well pour your money down the sink. Carbide? Only for very special applications with super accurate machine spindles.The common twist drill bit is still the most efficient metal removal tool ever designed regarding cubic inches/horsepower/minute. It is also the most abused metal removal tool ever designed.McMaster-Carr pricing is fine. Another source is Suncoast Precision Tools https://www.suncoasttools.com/The worst gimmick? Anything that is TiN coated and made in China or India. Buy cheap, expect garbage. A plain Jane American simple high-speed steel uncoated drill bit will outperform these gimmicks any day.Just some suggestions and one good video from Youtube, that I hope will help.
Reply:I have a $100 precision twist set in HSS, as well as a $80 Harbor Freight cobalt set. They're both equally good at drilling holes... The downside is sharpening the harbor freights is tough because I use a drill doctor and it pretty much doesnt work for those bits unless you have 4 hours to kill.Last edited by BrooklynBravest; 11-13-2018 at 05:50 PM.www.FirehouseFabricators.comZachMillermatic 255Lincoln SW200Hypertherm Powermax 45xp2x4 CNC Plasma Table.

Reply:Back when I was an apprentice tool maker we made custom drills with HSS for the manufacturing shop to use in production, lead man used to tell me we had to make them faster and cheaper or they would buy them , Years later i was working in a sign shop and I sharpened some drills on the grinder , owner said not to do it as the last guy couldn't sharpen them to save his life ,they all wobbled he was amazed when they drilled true holes. only HF drill bits I used were crap,Boss though he got a good deal on on a set of that rainbow colored junk, they would round over on the first or second hole.
Reply:See if you can find a Cleveland Twist drill index in cobalt for under $100.. Cleveland makes about the best drills I've ever seen, besides the inserted or solid carbide drills.. Precision Twist Drill is another great brand, might be cheaper than the Clevelands. Also do yourself a favor a purchase a carbide spot drill while your at it .Last edited by brucer; 11-15-2018 at 12:37 AM.Do any of ya'll use the stepped hole cutting drills and if so what brands do you use?

haven't broke one yet but i tend to be a little careful with drills in general... although anything below a 1/16th in a hand drill is just asking for it

Reply:Back to twist drills. You might want to look at Cle-Line drill bits. They are usually 135 degree split points and work extremely well on metal. Bonus: They are made in Seneca, SC. Bonus 2: They are not especially expensive. Available at the usual places including Home Depot.

Reply:I bought the drill hog m 7 off of ebay they are way to brittle I chipped the 3/8s in the mill. And snapped off several of them hand drilling, absolute garbage was going to warrentee them but all i will get is more crap that chip when they break through or snap off deep. Ihad a set of irwin max i really liked got dozens of holes out of each one. Replaeced them with another set just like them. they had changed the heat treatment and would snap off if you breathed to hard on them. All my hand drilling is done with a milwaukee hole shooter without the second handle. I have twisted the shanks on the harbor freight silver demming sets. nothing quite like untwisting your drill bit.Do not argue with an idiot. He will drag you down to his level and beat you with experience.
Reply:I don't think I've broken a single bit in the drill press since I slowed it down to 80 rpm. I do leave a little slack in the belts so they slip when it jambs.

Reply:On the steel corrigated decks I've drilled thousands of holes with these for bang it's inserts all different brands usually Lenox but that's just what the supply house sent, they make sense in alot situations, most pressure and heat is on a initial hole after that it works like a annular cutter

Reply:X2 for CLE-LINE, available at home depot and lowes, made in USA, good metal, sharp, competitive pricing to norseman. I've had good luck with Milwaukee shockwave drill bits as well, but for pete's sake don't use an impact for metal drilling! I'm also a fan of the harbor freight step bits, they last decently and one cannot go wrong for price per cut. Use cutting fluid and go slow! Learn how to sharpen twist drill bits by hand (not that hard, 30 mins to competence, draw reference angle line on tool rest with sharpie), and learn to read the chip for pressure. Remember a hot chip (within reason) is taking the heat from the cut, when i use the step bit in thicker material the chips burn my arms if not protected. P.S. I bought drill hog m42 bits and they aren't the worst, though far from the best - sharpen extremely well but tend to chip on the corners, they're better than most in the drill press and about average in a hand drill due to chipping.Last edited by SlowBlues; 12-09-2018 at 10:12 AM.

Reply:https://www.wttool.com/index/page/pr..._shopping=trueForgot who makes them, but very good bits. Actually ground properly. Handy to have all the sizes, especially if you do a lot of tapping.
Reply:I have a funny HF story: when south, visiting grandpa in Santa Rosa, I stopped by the local HF store and needing some extra weight in my baggage to replace that of the canned salmon just dispensed, I could not help but buy an on sale 29 pc. super-duper drill set (tiN coated, of course) for $19! They MIGHT be useful as a nail, in something like balsa or perhaps used to remove hardened ear wax. Of course I knew better! Of course I couldn't help myself! I'm pretty good at sharpening drill bits but alas, they are still nails with a twist. Sure looked good, though...I've had a 29 pc. set of Hanson's HSS (now Irwin) for longer than I can remember. Most of the wear is dingle-berries on the shank. Though it is true that most of my work is with AL, still, they will pass on ready-teddy after I croak.SO...here's my offer to the OP's query, and cobalt to boot: https://www.amazon.com/Irwin-Tools-3...+drill+bit+setLast edited by Yofish; 12-13-2018 at 12:08 AM.
