Hurricane hand drills?

Hello everyone

Do they still make hurricane hand drills? looking to compare the differences between a Hurricane and the petzl rockpecker before making final decision on which one to purchase. I've used pika's drill, but did not like the fact that I would have to re tighten the bit every so often. Does anyone know which system hurricanes use to accept the drill bit? Is it similar to the rockpecker? Any advice would be appreciated. Thanks

I don't think Hurricane Mountain Works drills have been made in a few years. However, you see them go up on the boards or ebay once in a while.

As far as how they attach bits; they use interchangable collets that fit into the main body of the drill , with a nut that fits over the collet and screws onto the main body which in turn holds and clamps the collet onto the bit. Seems to work well. I don't know how that compares to a rockpecker though.

I've tried all sorts of hand drills and have found that SDS bits work poorly by hand, so I don't think that the main problem is the method of holding them.

I truly believe that Star drills are MUCH faster. Fortunately in soft rock they don't dull quickly, but sharpening is where many screw up. It helps to bear in mind that a bit is a chisel with 2 edges and 3 points.

Its the 2 outer points that get worn fastest and one must beware not to allow the diameter of the business end to taper as binding can become much more of a problem.

Just my $.02

Rocpec only uses SDS bits. Hurricane drill is purported to accept any bit. See picture of Hurricane drill here:

Rocpec here:

I have used a number of hand drills. Depends on what you are buying one for.

For an emergency type bolt kit, the size and ease of bit changing in the Rocpec is hard to beat. With a 10mm Hilti 4" bit, the package is very small. I custom cut down old 6" bits to 4" for use in real soft rock, also a small package (no carbide tip, dulls quickly, but, for a couple of holes in real soft rock, works ok, but, bottom end of shaft is slightly bigger than 3/8" so hole has to be a tad blown to get all the length for a longer bolt, fyi).

If you want to switch out bits on the fly, rocpec is easy. To change a bit out, just pull back on the collet, pull out the bit, insert new one, bingo. Its that easy. Its also a nicely designed unit with a nice rubber handle and a keeper sling attached, which also is used to snug a drill bit up to the handle for transport (nice compact package). My only complaint is that sometimes when you're drilling with a rocpec, the collet will "bite" your hand. This can be very annoying.

For pure hand drilling, I dislike the SDS bits. You can custom sharpen them, but, they never seem to drill near as fast as a good ol' Rawl bit.

So, if I knew I'd be hand drilling 3/8 diameter holes in granite or harder, I'd be using my old Rawl holder and drill. Heavy, bomber, and fast. Also, easy decision for me since I still have a stock of drill bits in 3/8, 5/16 and 1/4 inch that fit the Rawl. If I didn't have a Rawl set up, and could get a Hurrican drill, under the same criteria (knew I had to do a ton of drilling by hand), I'd probably get one.

I've used a Hurricane drill, but, my experience was a tad tainted as the collet became loose, and my partner had an idiot cord on all the wrenches, and was a cluster, getting dark, I was scared...but...once a drill was firmly attached, seemed to drill just fine.

If I wanted an emergency bolt kit drill, with the ability to change bits quickly, I'd go rocpek. Also, nice back up to a power drill if you're worried about that sort of thing...

Another emergency bolt kit idear is to surf ebay for an old rawl drill without the rubber handle. Folks cut the holders down and with a 1/4" drill attached, makes for a real small package.

So, kinda depends on what you'll be using a hand drill for, methinks.
