N.W. Iowa | I just bought a set of Drill Hog bits. Made in USA. Work very well so far. Getting harder to find bits that aren't made overseas. Lifetime warranty on broken bits.

| 135 degree split point bits drill better, don't need a pilot hole and don't jump around from the center punch mark because they cut to the center. I have a couple sets from Menard's that I haven't yet applied. 12 piece set numbr 236-5167 1/16" to 3/8". 160 pieces number 242-3567 was on sale last summer. Many copies of the smallest sizes 3/64" up to 1/2"
I have bought a few larger 135 degree split points at various places including McMaster-Carr and that one from McMaster-Carr is still good after drilling more than 60 holes in 1/2 and 3/4" steel. I did touch up the cutting edges after about 50 holes.

| Cobalt bits. More expensive but the death of bits usually comes in the form of harder metals. No bit will stand up to abuse so if to chip them and break them because your pushing to hard or aren't drilling straight, then there's not much you can do.
If you ever need to drill really hard metal, take masonry bit, sharpen it at 12 degrees, and it'll go through anything. I've never had a metal yet that I couldn't work with carbide. |

Out of Minnesota. Free lifetime sharpening, lifetime warranty if you buy them at a show. (they should be at the NFMS in Louisville)
EDIT: AMERICAN MADE DRILL BITS is not the correct company. AMERICAN MADE SALES is the company, they do not have a website.

McCanna, ND | I just got a set of Norseman a few months ago. Very nice bits and aren't any more money then nicer "tool" company bits. None of the cobalt craftsman or dewalt bits I've had compare to these |

What are some good sets of drill bits for metal?
HF high speed steel drills and a yellow can of Mistic Metal Mover cutting fluid to keep them cool and lubricated.
From a tiny pin drill to 1 inch, will cost little if any more than $50 including a pint of MMM. |

|
North End I-15 | Big plus on the Mystic Metal Mover . Best drilling fluid I have ever used .
Worth every bit of the cost.
Formulation was changed a few years ago to remove the carbon-tecna-chloride (sp) which leaves the surface a bit oily compared to old formulation.
Buy it by the gallon . :>)

Central Minnesota | So does the lifetime warranty not apply if you order from them directly if you cant make it to a show? |
|
| |
|
Hillsdale, IL | That's what I was told...but I bought them at the show. I can't find anything about a warranty on their website, and when you buy them at the show they fill out a card and check a box for warranty that you have to keep. I think they keep a copy of it and have a record of who has a warranty. |

| I'll chime right in with Jon and Ernie on the Mystic.....best stuff I have found to cool / lube cutting tooling, and I have tried plenty of others, but I am still partial to WD40 for aluminum.
When drilling SS, go slow.
I have always like Winter's bits, and the ones from McMaster as well.
Per previous posts from Ag Talk, I just bought my 1st set of HF bits a couple of weeks ago, and will soon be putting them to the test.
Be cautious when using cobalt bits, they are hard and brittle, cut good, great in drill press and mag drill, but they dont like that reaming a hole once you are thru.
Agree with reply above about the carbide masonry bits too, if sharpened correctly and run slow and lubed liberally, they will bore thru some very hard material. |

Manitoba | I bought a set of Viper brand bits from a company in California. They said they were guaranteed for breakage and loss, but they don't keep their word. They are some good bits but I won't buy from them again. They use high pressure tactics. The bits from 3/16" up have 3 sided shanks. |

| Drill Hog bits. The company really takes the time for customers questions and to make sure your satisfied.. Had a mix up on one set I bought and they took care of it with no problems.. Gave a full refund and said to just keep the bits .. To make things even more right he sent me a set to test for free and offered if I did not like them he would pay me for trying them out.. Cobalt M42.. very happy.. they have diff. levels of bits.. this is what he sent to help me understand what they all have..
Titanium - Old material. We don't make them anymore but still have old stock.
HI-Molybdenum M7 - Latest and greatest stuff. Our #1 best seller.
Cobalt M42 - our strongest drill bit period. Great for stainless steel.
Niobium Nb41 - these are specialty drills. We sell mostly to locksmiths and gunsmiths.
They work good only for certain types of steel.
M4 Tungsten-Molybdenum - these drills started our company!
Old material but we still make them because we have many old customers that swear by them!
Cobalt M42 are more expensive than HI-Molybdenum M7.
It is more expensive as a raw material and to produce.
So if you look at any set that is Cobalt M42 you can expect to pay more than the same set in M7.
For most customers the HI-Molybdenum M7 works fine because they are excellent quality and an
affordable price point.
If you want the best and your pocket book allows, go with the Cobalt.
Test the Cobalt M42 set I sent you and let me know what you think. |
