I have had three Hurricanes, gave one to Bobo. Now I have two. The last one I got recently off ebay for $50 brand new.

Darrin -
I think that the HS bits are sharpened to a chisel point and have the advantage of being re-sharpened easily as they dull. The chisel points work quite well. Additionally the bits can be purchased or cut to shorter lengths which are easier to use on lead. A lot of the holes drilled at Index in the early part of the ‘80s were made with Boeing surplus bits bought by the pound and then cut/ground to size. The down side is they can readily snap in two especially if you have crummy hammering technique. (like me) I’ve never broken an SDS bit in two but I have had the carbide tip fall out a few times.

Had no idea this would go like this. Great stuff Duece et all.Thanks for the information. I found this in a stack of gear a friend gave me (old drilled regular Chouinard hexes, Moacs etc.) Just wondering.

Minerals - you got it. I don't expect to do much drilling. Comes in the original A5 bag. What drills are you putting in there?

Pate.....flexy straws from McD? Oh yeah, those work too.

Well, I might be able to find one cheaper, but I’d rather give Tom a hundred bucks than play that E-Bay game…




I use these drill bits… to give Grossman nightmares!

Yeah, 17/64”……!!!!! WoooooHooo!!!

HSS bits are ground down to sharp chisels - SDS are pretty dull.

I used to think the HSS bits were over-hyped, but Minerals proved otherwise, drilling 1/4" more than twice as fast as you could with SDS.

There are still downsides, especially if you're lazy like me.

 you need a grinder (and a place to use it)
 you need a pile of HSS bits, which can be of variable quality
 you need a Hurricane (check, I have mine)
 you need the right collet
 you need to be quick and competent with your bit switching (which is not that easy with a Hurricane). Minerals is super good at that.
 you need to drill good holes since you don't get the leeway you do with SDS bits

The upside of SDS in a Petzl drill:

 the bits don't break very often
 the bits don't get stuck as easily
 quick, easy bit changes between 1/4" and 3/8" (or to replace bits)
 the Petzl drill is much lighter

I have some older SDS bits that I sharpened, and those work more like HSS. But all the bit companies switched to bit tips that you can't sharpen. And even if you have some old ones that you sharpen, if you are too aggressive with the sharpening, the tip breaks out easily - while with HSS you just re-sharpen.

Minerals- Care to explain yourself??? I won't be clipping your tiny but exciting bolts in any probability. Half inch stainless is way more dreamy and size does matter. LOL

So you guys have the SDS holder thing nailed down, do ya?!?

Out of the 40+ hand drills I have, the Hurricane is one of the best!
It was also available in titanium to make it lighter.

However these days, I am really loving my Petzl Rocpec.
Now I don't have to carry a bunch of extra tools to change the bits.
SDS click on, click off.

Rock on!

Spline to SDS adapter has been around for ages. Just cut the splines off and you are in business...LOL

Yellow plastic container is for the 25/64” collet.

Grossman, I was just poking fun, after reading your comments on the rap anchor thread. Will get to that one at some point here… Merely entertainment on my part. I’ll let you get worked up later. ;)

The yellow thing is a Kennametal Erickson collet box---- the plastic container that the collet comes in.

Hey Deucey,

I noticed that the hardened insert on the drill that Tom posted sticks out a lot more than the ones on my drills and on the drill that Pate posted. Some of the inserts on my drills are larger in diameter and some are smaller. Different batches? Any specific reason for the different sizes? I assume that the insert fills the entire hole (depth) that is shown on Tim’s CAD drawing, yes? Can I grind down the insert on the one that Tom posted so that the striking surface is almost flush with the holder itself? My current drills are pretty much flush, especially after a minor “tune-up” on the grinder. Also, are the inserts “frozen” and then pressed into a warm holder? Ho man, I am getting distracted from my geology work today…

Hi Brian-

I think for our first batch we extended the hardened insert. But after using it for a while on some new Zion routes, I decided just to make it flush for subsequent batches.

After I left Hurricane for the big city to work, I handed over the business to my partner, who then sold it to some local folks up in Colorado City (a very industrial lot, those folks... in many ways). Somebody mentioned a Titanium version--I had never heard of it, perhaps it was done by the Colorado City boys?

Cheers

I had the Titanium version on order through the Hiking Shack, but Dale was never able to land it. I believe it was listed for $30.00 more than the regular version. Maybe they never happened? However there was a catalog or products page that I looked at that showed the different drills offered.

Rock on!

Thanks, John! I guess I’ll take it to a grinder once I get it from Tom. Cool, a brand new backup! Thanks again for providing the climbing community with yet another awesome design which functions flawlessly!
