Re: o/t good drill bits
 

i have a snap on set that serves me well. All bits need to be sharpened from time to time.

Re: o/t good drill bits
 

have snap on cobolt bits,

a bit pricey but it is what it is,

oh and a drill doctor to sharpen them when they do dull

Re: o/t good drill bits
 

I have an older drill doctor and I hate it. I'm thinking about picking up a new one. How are the newer generation drill doctors?

Re: o/t good drill bits
 

here you go

Re: o/t good drill bits
 

I have a Snap on set, and a Matco set. I never buy cheap tools... :D

Re: o/t good drill bits
 

I know the feeling I actually have about 4 sets of snapons but ussually only use the cobolts... h*ll I think I paid for my snappy dealers house over the years

Re: o/t good drill bits
 

The Dewalts with the drill tip are actually very good. The most common mistake that I see is that people drill with the bit dry or way to fast. Keep your speeds slower and as much preasure as you can and don't let it wobble. I drilled about 16 holes through 3/16ths steel and it was still drilling as fast as the first one. They also do not need to be stepped up.

If you are using 1/4" drill bits use the stubbys and by from an industrial supply place. I buy over $5000 per year in drill bits and I have found that the stubbys or better known as aircraft bits are the best and last the longest. I am not in the office now to check the name brand, but it is the best bits I have every bought. I want to say they are viking, but I am not sure. I will check and repost tomorrow.

Re: o/t good drill bits
 

You guys actually own drill bits long enough to sharpen them?

Keep the tips coming, I am just like Open72.

Re: o/t good drill bits
 

Depends on material your drilling, size, drill, blind hole or thru? These will help determine # of flutes, angle and rake.

Re: o/t good drill bits
 

Greenfield, Clevland Twist are both excellant drills. Stay away from the imports, unless you just drill plastic. You can tell a cheap drill from a quality one just by looking at them. Like Audio said, speed, lube, and pressure are what will make or break a drill. Too many people think if you use a faster rpm, it will drill faster. Just burns up the drill faster. Rule of thumb, the larger the drill, the slower the rpm's. I resharpen them by hand. Peice of cake. Tried the drill doctor. I can do better by hand.

Does Snap-On (Blue Point?) and Matco actually make their own bits, or just sell them?

Re: o/t good drill bits
 

good info ,this is why OSO needs a tool tech forum.

thanks for the replies , i'm not going all out in drilling at high rpm , or forcing at low rpm , just seems that the drill bits aren't worth a crap these days. i need to buy 1 good set and sooo many choices , sooo, oso is the only place i know to get the best info...

btw , those drill docs really work??

Cobalt bits and keep them away from masonry.

Re: o/t good drill bits
 

If you know what you are doing. Seen many people use them only to grind a neg relief with them. That won't drill thru butter. But for most part, they are good for the home do it your selfer. Won't find one in a good machine shop. :p

any particular brand http://www.amazon.com/gp/search/ref=...20drill%20bits

Re: o/t good drill bits
 

I hate mine also . I guess i dont know how to use it??

Re: o/t good drill bits
 

love mine works great (drill doctor ) never had a problem with it

Re: o/t good drill bits
 

I only go into Harbor Freight Tools when I need something cheap and fast that I won't depend on more than twice.

I picked these up a a few months ago, and they have done very well for me. Not one break. (knock on wood)

Re: o/t good drill bits
 

A $20.00 bill is the best drill bit sharpener that I have ever had,,, works every time. :D I agree buy the best Cobalt you can find and takie care of them.

Re: o/t good drill bits
 

Snap On bits are made by Hansen get a set of those in cobolt and save some $$$$$$

Re: o/t good drill bits
 

I used to be a die maker. We drilled through 3+ inches of tool steel over and over all day long. A good high speed steel drill bit will last a long time if you use the corrct speed, enough pressure to produce a chip that comes of in a curl, and a coolant. A water soluable oil coolant can be purchased at any machine tool supply store. Sharpening a drill bit by hand is easy. You just need someone to show you how. I'd be glad to if you're in the area.

Re: o/t good drill bits
 

A broken bit is aggravating, but you can still practice your hand-sharpening on the stub if it's long enough.

The tip end (that broke off) can be epoxied into a "wire-nut" and use it to start holes in plastic or wood. If big enough, it can be used to hand-chamfer smaller holes.

Harbor Freight has a grab-bag of really good, but odd-sized, bits for $5. (Metric maybe?) I don't think I've broken any, and am not sure why I'm saving my Snap-Ons!

Re: o/t good drill bits
 

don't think i'm going to michigan any time soon :D thanks though :D

Re: o/t good drill bits
 

i have the snap on cobalts and some cheap titanuim coated bits i got at harbor freight i paid 300 for the snap ons and 18 bukcs for the cheap titanuims dont really see much difference in catting with one vs the other.

Re: o/t good drill bits
 

Don't worry You did :drink: :D

Re: o/t good drill bits
 

Agreed.
And never buy a drill bit at Wal-Mart, the auto parts store or a hardware store. If you want a good drill bit, get them from a machine tool company and its gonign to be like your boat. Expensive.

Re: o/t good drill bits
 

I think the cobalt is better because it is the same material all the way through the tool. Conversely, the titanium is just a coating and only provides surface hardness.

This is something like the Craftsman Tap and Die sets called "Krome-edge". Chromium is very hard, but once you break through the hard chrome, they are nfg.

However, I did buy the $20 titanium set at Harbor Freight at the blessing and endorsement of my fishing buddy who is a retired tool and die maker. I will see how this pans out.

I like the Hansen Cobalt bits the best, but can't find them around here. Even hold up well when drilling stainless steel. I used to buy them at Farm and Fleet in Wisconsin. Great products and cheap prices. Haven't been back in a while.

Re: o/t good drill bits
 

found these.. seems like a good price with free shipping

Re: o/t good drill bits
 

open 72;
those bits will be as good as you can find. I highly recommend them.

Check the mfgr's website for hints on drilling stainless steel.
The trick is to not let the bit skate on the stainless workpiece or it will work harden the stainless steel. Once you start turning a chip, keep going. Best to drill pilot hole first, then drill out to required size. May take two step of drilling before final hole. That helps the drilling process and helps to center the hole correctly.
