Answer: 
Yes...if you pre-drill a 16th hole first. A drill press works best with slow constant pressure. Lube oil every 15 seconds. High speeds will cause your SS to tarnish and the bit will cook then ruin...slow is good!

Answer: 
I would contact your local H.D. store Pro-Services department regarding bulk purchasing rather than requesting they carry that large amount available in-store for you to buy as needed.

Answer: 
This is something you would have to ask a distributor about. If you do not have a local distributor go to http://www.ridgid.com/Tools/Where-To-Buy/ and it will pull up who is in your area.

We would not recommend a cobalt bit for cement. We would suggest using a masonry drill bit for cement.

3/16 in. Cobalt Drill Bit is rated 4.1 out of 5 by 65.
Rated 5 out of 5 by from Rigid Cobalt Drill Bit I have used this product to drill out broken engine bolts as well as body work on my 1970's auto projects. This bit eats through steel like butter and holds an edge for a very long time. 2nd in hardness to Carbide this is a premium bit to use. Though a bit on the pricey side it is worth a bit that will last. Unlike titanium coated drill bits you don't have to worry as much about using oil and slow drill speeds as this is not a coated bit but a cobalt steel through and through. The titanium bits must be used at slower speeds with cutting oil to keep from loosing their edge (can't sharpen these cause you loose the titanium coating). This is a great product.

Rated 1 out of 5 by from returned pretty quick bought a set of ridgid cobalt bits on clearance at home depot to install some hardware on doors at a church here in town. i tried to drill through a push plate for a bolt using a 3\8 bit. all it did was spin. ive read how far superior cobalt bits are to titanium but now because of this purchase I am skeptical.

Rated 5 out of 5 by from Cobalt Drill Bit I used this to drill through thick sheet metal on autobody work. This bit is a beauty to use. It holds up to the wear of use and over the last year of continuous use has not dulled yet. I look forward to lifetime of use (if I don't snap it first). Though a bit on the pricey side it is worth a bit that will last. Unlike titanium coated drill bits you don't have to worry as much about using oil and slow drill speeds as this is not a coated bit but a cobalt steel through and through. The titanium bits must be used at slower speeds with cutting oil to keep from loosing their edge (can't sharpen these cause you loose the titanium coating). This is a great product.

Rated 5 out of 5 by from Long lasting. Really shape and held its edge for over 100 holes in 1/4" angle iron.

Rated 2 out of 5 by from Didn't break... Drilling out some magnetic stainless (400 grade) self-tappers in my grill that I'm converting to propane and a cobalt bit I got from the hardware store went through 24 holes in fresh 16 gauge stainless was still able to drill out two of these rusted screws on the burners. This Rigid bit went through one and took the Phillips pattern off the other three before going completely dull. Used low speed + oil. Got no smoke...the bit should last longer than that seeing as an old bit went through two heads and this one fresh could only do one. Went from screw to screw to negate heat build up in work. Disappointing to see a $4 single bit do so little.

Rated 1 out of 5 by from Won't cut 304 stainless steel May be excellent for other uses, but this very expensive 1/4" bit won't cut 3/16" 304 stainless steel, with or without lubricant even at low rpms. Perhaps split point angle is wrong. Does not appear to conform to 907 spec. Took many hours alternating pounding with a nail punch just to drill one hole. I still have 3 holes left to drill.

Rated 5 out of 5 by from Finest Drill Bits These cryo treated cobalt drill bits are fantastic. I had a project that had a lot of rivets into 1/8" steel and 26 gauge sheet metal. I started the project with a TiN bit, thinking it would do the job, way too much work. These holes I made were drilled with a corded drill, free hand, standing and kneeling and in awkward positions, so it was hard to keep the drill aligned. After four holes with the TiN bit, I switched to this bit. Over 300 holes later, I was still getting curls, the bit was showing a little wear, but holes were made quickly. If you have to drill metal, use these bits...

Rated 2 out of 5 by from Hit or miss The quality of the bit was hit or miss. I bought several of the bits because I was drilling 100+ holes through 1/4" steel columns. The first bit worked like a charm, cut over 70 holes before dulling the bit. To finish the project I had to open three more packages to get a second bit that worked as well as the first. Product works great when it works, but it appears that there are quality control issues.
