    Default Chasers

    Have just been given 30 sets of used metric & unf Chasers with a machine I have just bought. Do any of you guys know if it is possible to use them without a diehead?

    Are these Chaser or sets of 4 numbered dies that would normally fit into a die head.

    I saw a dealer suggest you could weld handles to them, and use them as hand held chasers.

    Actually Jordon not a bad idea - not the welding thing - rather swapping them for some taps at a dealer's place. I am tapping stainless at the moment and going through taps by the bucket load. I am right at the tolerance for drilling diametres so more taps is the only solution.

    Or you can use them as threading tools by putting them in the tool post...

    I have used pipe chasers to thread pipe on the lathe... That way you get the tapered thread right...

    John Stevenson showed an example of this on one of the forums several years ago. When I needed to make a duplicate of my 10 TPI lathe headstock spindle thread I borrowed the idea, and the finished correctly shaped Whitworth profile thread turned out very nicely indeed. The partly cut thread is shown below. This chaser had been discarded because it had a chip out of one side, which was ground away to avoid any thread damage.
