Super Drill

Super Drill

An Australian invention that allows you to drill any size hole from 1/2" to 2" (12.7mm to 50mm) in steel and timber.

Designed to fit into your standard drill press the super drill works using 2 specially designed fully adjustable cutters to easily cut holes any size you need, using no more than finger pressure needed to get perfectly clean round holes every time.

Cutters are re sharpened using a diamond lap or hone and can also be replaced when they wear out.

There is a design patent on its manufacture but could be made for personal use.

I haven't looked at the video because I get an overlay from Google. They rabbit on about 'data protection' but it's simply a way of ensuring you have signed up for adverts whether you want them or not. And I don't; if nothing else because they're totally irrelevant.

Just watched the video, no adverts or overlay. A kind of flat trepanning tool, very agricultural.

Andrew,

Instead of using the link, try a Google search for: Robson super drill

or the Tooling site who is selling it: http://www.toolking.com.au/super-drill-pack-large-metal-drill-bit/

Looks like a variation of a basic economy boring head with a differently ground tool bit to me.

Edit :- And by the look of that link given by Paul a very overpriced one at that.!

Certainly nothing novel about that. Had similar tools in the departmental workshop back when I started work in 1972 and they weren't new then. Pretty sure I've seen references to similar in some of my Lindsay reprints. Idea probably dates back to pre WW1 or maybe earlier.

Very much a get out of jail tool only used when nowt better around. Setting to size needs an accurate setting ring unless plenty of wobble room is acceptable. Also tend to wobble about unless there is a nice fitting pilot before and after the cutter. Boring out a pulley accurately on a drill is pretty much impossible with the basic system. Even with pilots needs care and luck.

Market driven, overpriced near tat. Looks a good idea but looks ain't everything. I doubt if a good implementation could be made at a viable selling price.

No adverts here. Does seem expensive at about 140 quid

Just a modified trepanning tool with pilots... not saying it isn't neat & would make some jobs easier...

Not new, I saw adverts (Oz) for this 20 or more years ago. Agricultural perhaps but that is almost certainly the market it's aimed at. Tidier result than a hole saw.

I haven't looked at the video because I get an overlay from Google

Kill all your cookies and the adverts will go away, I had thousands of cookies the day I started using cookie manager, now I have none

Simply going in to a well known auction site, having a quick look around, then leaving, puts about 100 cookies on your computer

They are tracking every move you make nowadays, mainly for advertising purposes I presume

I wonder if anyone has ever tried to use one in a hand drill.?

Not those but I have used the very similar flat blade type counterbores in a gut-buster drill to produce a flat bolting surface on a rough finished casting. As I recall thngs it went quite well with the usual technique involving plety of lean and steady turning. I suspect that doing a complete hole rather than just facing would ahve taken a fair while. Obviously effective piloting both before and, probably, after the cutter will be pretty much essential tos top things walking around and jamming up. An obvious pain with after cutter supports is obstruction of the chip evacuation space but the swarf comes off fairly slowly so a strategic slot ought to work.
