    Default Air angle drill question ?

    I want to buy something like this for a jig.
    http://cgi.ebay.com.au/eBayISAPI.dll...m=200216153901

    Never used air drills before. All I know about them is there bloody noisy. The glazier next door runs one all day.

    I know this one looks like ????? quality, but generally would a tool like this be able to drive a 5/8" spade bit into hardwood no problems ?

    I assume it would, but just checking uno.

    I could be wrong but my understanding is they are designed to run short bits at high RPM and driving any spade bit at 15000 rpm might be asking for a problem. Yes you can bog them down to low revs but they will then lose power and spade bits need grunt.

    Running a spade bit at/near 15000 RPM would not be a good idea.

    I tend to agree with , air drills generally have no torque. Great for drilling holes for pop rivets but once you start getting up to 5/16"-3/8" size bits, it starts to bog down and more often then not the bits just grab and stop.

    you reakon ? Even if the spade bits cut right down to just a couple inches long with it sharpened with spur tip centred nicely....How about a 1/2" ? 1/2" is probably all I need. I don't need to go too deep. Maybe 20mm deep.

    see what I'm after is a means of drilling in a tight corner. I suppose I could buy a angle jig for my cordless, but I'm thinking even it will be too big for the area I intend using it. like the compactness of this air tool.

    oh well, try something else.

    Thanks for the help.

    I'll walk in there next monday I will. with a block of wood and a spade and ask him if I can try it out. See what happens. just that My 14.4V cordless seems to pull it off, and these air tools make so much noise.....just sound so powerful uno.

    Sounds like I need a mains powered one. Uno where I can get a cheaper version of one of these from ?

    Be perfect, because the threaded holes on the side of it where you attach a handle can be used to attach my jig.

    Jake,

    Just for you I just tried it out on my die grinder in a piece of Jarrah. It's a 22000 rpm unit and could not get it to drill past the tip of any spade bit bigger than a 3/8" spade - it just bogs down, maybe the lower revving air drill will be able to do a 1/2"

    After a bit of mucking about I got the 3/8" to make a hole reasonably quickly (maybe half the speed of a regular drill) by using light pressure to jockey the rpm between full revs and slightly less than full revs and kept clearing the sawdust out of the hole. I tried it down to a depth of about 20 mm. With practice I reckon you could do it a bit faster. I thought it would just burn the wood/bit but it didn't.


    Cheers

    Hi Jake,
    You also have to have a decent compressor, the one next door to work would prolly be bigger than the one you have at home?
    A mate just bought a cheap angle attachment for his electric drill off Ebay, and raves about it. That could be a cheaper option.

    Cheers,

    Change is inevitable, growth is optional.

    thanks everyone for the ideas. And Bob for doing that.

    I pulled my finger out and dashed down to mitre 50 and bought this warrior thing for $35 just to get an idea.

    Said on the box 2.5Hp compressor minimum. Mines 2Hp only.....but it was fine for a 5/8" bit.

    Imagine it be a pain if I had to do a lot of holes, having to wait for the compressor to charge up all the time, but with this jig I'll be doing single holes every minute or so anyhow. so problem solved. ta.
