    I just want a good quality drill bit is that to much to ask? I have bought a lot of sets from a number of companies, all sorts of coatings etc.. I have spent in access of 100 dollars on sets and have to say the price doesn’t mean they’re better. Does anyone have suggestions on where to find a good set of drill bits???<o:p></o:p>

    For really good high speed bits I go to our local steel supply house that also carries equipment and tools. But I also like the Dewalt pilot point bits a lot, like Home Depot and Lowes sell. They hold up well and are agressive as hell.

    Surprisingly, I have had good luck with the gold ones Harbor Freight sells. For the money they really aren't bad, but I use my Drill Doctor pretty often to keep all of them touched up.

    If you can find the ones that Lawson sells they are some of the best I've used for drilling steel.

    scroll to cutting tools, then drill bits and take a look at the Regency grade of bits. I've still got most of a set in an index that I bought from them over 20 years ago. They aren't even close to cheap though.

    Right now though, my grab and use it bits are in an index that I got at Costco that has Kawasaki drill bits in it. Lots of bits that you use for the 20 bucks that they cost and they work pretty well but only go up to 3/8.

    I'll be honest, I rarely use cutting oil because of the mess it makes and I don't like oil all over something I am going to paint. Even holesawing is something we do dry. I know it chews up bits and holesaws quicker, but I just hate oil all over everything.

    That's been my experience too. Pretty good quality for the money.

    I buy indiviual cobalt drill bits in only the sizes I use most often at my local hardware/industrial supply. Waste of money buying index sets as far as the home builder is concerned IMO.
     
  9. Go to industrial supply houses instead of the typical hardware or home improvement center. Any town with a concentration of metal working industries shpuld have one or several "mill supply" houses that sell name brand drills like Cleveland Twist Drill, Precision Twist Drill, Chicago-Latrobe. Wholesale Tool has a location in Stoughton, MSC is in Springfield, Burlington, and Worcester.


    And, of course, the advice as to cutting oil and proper speed is still highly relevant. You can ruin the best drill in the world if you don't treat it right.

    I have a set from Home Depot of Dewalt and they have been the best so far. Like Don I have more than one set although I don't have a good sharpener. How about posting yours Don, I'd like to get one.

    X2 on cobalt bits. Keep them lubricated and use them for steel only.

    Yep... The biggest enemies of drill bits are friction and heat. These are amplified by running to fast (speed) or pushing to hard (feed). When drilling into metal, cutting oil is an important part of reducing heat and friction. I feel that if you buy cheap, you get cheap. Cheap bits tend to be softer and become dull quickly. Because I know a technique for sharpening them on a bench grinder, I can keep touching them up. My preference is to spend a little more on high speed bits (HSS). There are many brands. Look for bits that say "Cobalt" or "Titanium". They are made for higher use, production runs and will drill the hardest of metals all day long. When going longer distances, look into using "peck drill" techniques, to clear the chips and to reduce heat and friction. What ever you decide... cutting oil and technique will keep you going a long time;)

    i had the same problem, so now i just buy up old ones at auctions when i see them, no companies seem to have pride in what the throw out the door anymore to the public
     
  14. I have also had the best luck with the Dewalt Bullet Point drill bits. I started buying them 10 or more years ago when B&D came out with them.
     
  15. I'm still using my 20yr old set of Snap On bits, fractions,letter,and numbers. I have destroyed a few but over all very little trouble with them.

    Must use correct rpm.
    Coolant helps.
    Resharpen when necessary.

    I have owned a machine shop for 27 years and I find it is hard to beat a Cleveland Twist or Chicago Latrobe drill bit. I don't wast money on the coated ones because as soon as you sharpen it the coating is gone. I use high speed steel unless I am drilling stainless or a exotic alloy, then I use the cobalt. I use a water base coolant in a pump squirt bottle.
    The speed and feed mean everything in the world to drill life. JC

    I use Drillco Nitro bits that I keep well-oiled when drilling through everything.

    Got' em at a local supply house. They're the best I've ever owned.
     
  22. I'm in the machined parts business too. Agree that you're best off with the name brands, which I get from MSC mainly.

    I like the TiN coated ones on steels, anything under 3/16" I consider a throwaway and factor a certain number of them into any I job quote. Cobalts are always good too. Unless I'm doing deep holes, I get the shorter screw machine drills if they're available.

    For hand-drilling operations on cars, I'm a bit less fussy about them as they take a beating. Anything in a HSS will do.

    I agree on the cobalt screw machine length drills i usually use tapping fluid applied with a flux brush. Speed kills.

    Also, depending on the diameter of the hole, piloting the hole with a smaller bit will extend the life of the more expensive larger bits.

    I drill half inch holes very regularly installing receiver and fifth wheel hitches in the frames of trucks.
    I pilot them with a 7/32 or 1/4 inch bit then step to 1/2 inch.

    I use pb blaster for a lube, works pretty good.
     
  25. cobalt 135 degree the tool places like MSC sell them and wholesale tool, buy on sale and put in a Houot drill cabinett with room for spares

    may as well get a set of # bits at the same time, slow speed is the key, a air drill will smoke or break a bit quick

    I use plain old steel bits, I just grind and sharpen them properly and they work just fine. Unibits are another story. I've just can't seem to find good ones.

    I second the NITRO brand drill bits.
    Usually you can get a set for less than $100.
    Mine are from K's surplus bolt store.

    They are the best.
    I've got 2 sets,
    one brand new,
    the other one used but basically new,
    and a bunch of extras in the popular sizes I thought would wear out.

    The extras have held up so well,
    I've rarely used my (first) set,
    and never use my backup set.
    And this is about 2 years now of moderate to heavy use in steel, aluminum and stainless.
    I do know how to sharpen them with a bench grinder,
    and it is amazing how sharp the tip stays even with my hack skill.

    I do like oil and low RPM's and also not too much pressure.

    Ive gone threw an aweful lot of bits finding ones I like. I love Irwin split tip black carbide<- black something?
