Thanks guys! I am guessing that you can drill faster with a HSS bit compared to a SDS bit because you can put a really sharp edge on the HSS bits.

bryan too funny, i should have took a photo of that holder john had when i had the chance. super small and perfect for your stance drilling, i think the bit is a press fit, or temp. fit and looks sorta like those old 5.10 bits that had no flutes but a flat on both sides to make an easy chisel on the end. i'll email john and see if he will post a pic

How many holes are you guys getting per bit before sharpening?
Irwin-25/64ths got me 2 in Bullet hard granite, then needed to sharpen.

i'm usually just fixing anchors, and usually widening a 1/4" hole with sds, and then change to hss to make it deeper once ive gotten to the bottom of the 1/4" hole which is totally worth the time spent in changing the bit. so while i try to use the bit for just one hole, sometimes i'll go for two, and have even done three in granite without sharpening. sure is nice to have a fresh bit in there, makes all the difference, as i'm sure you know. takes out small chunks instead of making powder like sds
with the hurricane its quite a bit easier to change bits than my old rawl #20 holder, which was more difficult to do changes

I don't pay more than $20 for a holder, screenshot taken today:
Nice little 3/8" by 2-1/2" A-Taper drills can be had. I get them for less than $10.:

When you buy an A-taper holder, buy the ones with a round wedge for diving out the bit, the flat wedges don't work as well and get jammed.
Don't buy this kind:
Saw it off to shorten and lighten it. Use a bicycle grip or old inner tube to make a handle.
Relton in Arcadia California has genuine made in the USA holders and drill bits.:

When I am home, I can measure the length, weigh it and photo it.

Here's the iron spud. 8 inches long with the drill installed. The drills are made by Brinker Brown and are 4-1/2" overall with 2" useable. It is a bit heavy at 400g (with bit installed, bit is 50g). A foam bicycle grip handle would be lighter than the inner tube handle but I like the inner tube handle since I can make it big enough for my big hands. You could cut it off shorter too.
The drill bits are available for $6.55. Item A3754 made in the USA here:
http://www.buydrillbits.com/products/masonry/step2.php?s=ATaper
So, buy the holder for $10, get a bit for $6.55 and you are good to go.
I also have a $20 hammer that I like.

Yup John's work...the drills, bits, hangers.
The bigger "sportclimberspackage" drill has 20 or so holes on it.

OK, I have to hit John up for one of those 4 OZ drills. Perfect for backcountry occasional use, no? How many 1/4" holes can you get on one HSS bit? Weight of the bits can add up. Maybe fit it with a 1/4" dia carbide tip bit for longevity?

Ss on the hangers
The bits are good for at least 6, and then a sharpen, repeat for years.
Crags- exactly.

How is the bit held in?
I've used HSS bits, the ones I made out of twist drills only lasted a hole or two but they can be sharpened with a diamond file as can carbide bits. Since the shaft and the point are the same diameter, they can bind up.

From the developer
Intended to be super-light and pretty much "disposable".
1/4" dia HSS or solid Carbide bit. Shaped like old Rawl or 5.10 type bits. Sharpenable as many times as needed.
My theory on why the bits work so well is that anything with flutes is pretty much a stretched-out spring in shape and will dampen a hammer blow. 2.5-3 mins a hole without really trying.
Annealed(soft) handle. Doesn't really mushroom too much to worry me enough to harden them, and you have to sharpen the bit on a grinder every once in a while anyhow, so clean up the mushrooming when doing so.
The bit is semi-permanently taper-pinned perpendicular to the bit ( there is a cutout ground into the side of the bit that the pin crosses through). You should, in theory, be able to get the pin out and replace the bit but I have not tried yet.
>>>With a small rack of SS hangers, buttonheads or 4 piece powers, a 4-6oz drill, you are light enough for a real backcountry application.
Items available upon request. Just trying to keep the dream alive.

Bump for the mini beat stick.
What's the word, from all five of you 1/4" drillers out there?

looks like a great way to go, seems like you would want to have two of them on you, so if you were way out and for some reason broke a bit you could still work. have you guys tested the mini version? i am curious how much two of those little guys would set me back, does definitely look real good for the back country routes, or for wall f.a.'s. thanks jg for the pics! very cool

We are just trying to get an idea if/how many would be interested in a light drill kit.
The Bits are where its at. John has placed around 6- 1" buttonheads with the bit without sharpenening.
I will send some PM's out to those who are interested. Proto's are floating as we speak...
Klaus- That drill is choice, great history. Not very beat up though?
My current rawl holder seems to be softer than the first one I used. Lots of wear.
Cheers!

I decided to goof off in the garage for a little while this afternoon and see what I could come up with.
