Amazon is running a $20 off coupon on Chicago Latrobe 550 Series Cobalt Steel Jobber Length Drill Bit Set with Metal Case, Gold Oxide Finish, 135 Degree Split Point, Inch, 29-piece, 1/16" - 1/2" in 1/64" increments. Normal price $223.03 less $20 coupon.
Years ago I worked in a machine shop that used CL Gold Coated drill bits. If you want an excellent drill set. These things will last forever, buy this set. These are not the cheap DeWalt, Irwin or Bosch drill bits you get at the hardware or big box store. These are the tools of machine shop quality that will drill most steels. Made in the USA!
Here is a link to the detail page: http://www.amazon.com/Chicago-Latrobe-Series-Cobalt-29-piece/dp/...

Like all coupons at Amazon you never know when they are going to run out.

wow, nice high quality bits and made in the good old USA. not much of that around anymore. Thanks for the post.

Cant beat this deal -- Thanks for posting

i take it these are better than the chicago brand at Harbor Freight?

Gold oxide or solid gold? When I saw the title, I thought that this must be a set with hundreds of bits.

Well, I've never used them, so I can't say that they aren't worth it, but I can say that they have been available for around $150 as recently as last fall.

They may smell like pumpkin pie too but I'd never pay that. Then again, I'm not a "professional".

Purchased this set for my son. He said they are great for drilling out broken bolts. He has owned other drill bits sets but said the Chicago Latrobe bits work the best. He uses them at least once a week in his shop. Will purchase another set for my son-n-law now that they are running a deal

I actually bought the HF set of cobalt steel drill bits when I need to do some drilling through stainless steel. Cost about $79 w/ 20% coupon at the time -- most I ever spent on drill bits At that point I don't think they had the smaller set available now or I would have probably gotten that. Anyway, they worked just fine for my limited use, cutting through stainless like butter. Well, really hard metallic butter, but you know what I mean.

I'm not gonna even try and compare the quality with the OP set, but for limited use in a homeowner/shadetree mechanic setting the HF *cobalt* set is pretty good. Worlds apart from the cheap titanium nitride or HSS sets.

unless someone has a regular task of drilling metal, average people don't need $200 drill bits....for anyone who can't decide if they need them
