Title: Mystery Tool
Post by: richald on June 15, 2013, 08:18:19 am

 Anybody know what this is exactly? and who may have made it or sold it?
 
 I picked it up from an odds and sods tray at a show somewhere many years ago
 and no, I can't remember when/where!
 
 It is probably the most used tool in my toolbox - it can be used as a drill i.e. like a
 plunge router bit, and can be moved sideways to mill out material - it is particulaly
 effective on fibreglass !
 
 Shank is 3.0mm dia. and cutting 'end' about 1.6mm dia. - If I could get hold of some
 more like it (in different sizes) I would jump at the chance!

richald............my machining knowledge is limited  %) .....but it appears to be a "multi fluted spiral drill tap" .....
These were designed for use in production machinery......but there is absolutely no reason why taps of this design cannot be used in manual tapping in predrilled holes
I am sure a member with superior machining knowledge will elaborate here  O0 ......Derek

Its called a spiral fluted tap and is used for cutting materials produced in continuous coil form, such as carbon steels, alloy steels, and nonferrous metals.
They are available in all sorts of different sizes from machine tool suppliers, a quick Google should locate a supplier close to you.
Hope this helps

Dont think it'll be called a 'tap' persae , is it solid carbide? (a light grey all over) the teeth are for chip control , mega bucks to buy these things, a uni-directional finishing cutter or something like that, your best bet is a classic car show auto jumble tool store & look in the carbide tool sections . . . as you say a useful piece of kit . . . I've broke all mine  :embarrassed:

Derek / Paul

It hadn't occurred to me that it might be used for tapping - any
thread it would generate now would probably not be very good
given all the welly I've given it over the years - I will try putting
it through some softish Aluminium sheet and see if it generates
a thread. Another point : all the taps I've seen images of, have
a square section on the shank, this one is circular all the way up
the shank.

I'm inclined to go with Bill's thoughts - material could be carbide
I shall look round the interweb a bit more - see if I can turn up
something that looks like it.

Thanks very much!

Thanks for the info Jimmy but ....

One Router Bit 4.53€
Post and Packing 27.00€

and if I have read the terms and conditions correctly
that would be plus either Polish VAT @ 23%, or UK VAT @ 20%

Kind of makes it expensive!

Current best bet is to plough through all the various offers
from imsinking's Israeli Ebayer (some of which are P P free)
and go for some of those.

I'd seen the American ones on ebay - but what none of the sellers seem to
do, is offer say, 5 bits of different sizes - it's either 10 off all the same size or
50 off, 5sizes, 10 of each.

thanks for all the replies, chaps, they are much appreciated - at least I know
now, what they are !

hey guys. Look under the name 'Rippa' Thats what we call them here in the uk. Primarily for roughing out material. The ridges edges cause the milling cutter to chip better and enject material quicker. Allowing faster feed and quicker material removal.
