Anyone recognise these.

Does anyone know what these cutters are & what they are used fo. They came with a lot of milling cutters that i bought some time ago.

Steve.

They all look pretty boring to me

the one in your hand looks like it has a broken insert. They could be used in a boring head in a mill or in a lathe.

It does look broken but it is how the cutter is made. Seems to be a radius type thingy.

The one in your hand looks like an insert ball nose cutter, one to the right of the line up an insert CSK/chamfer cutter. The others insert end mills

Maybe a ball nosed milling cutter.

edit: Jason types faster than me!

The 2 on the left could be single point milling cutters.

So would the ball nose cutter be used on the edge of a piece of work creating a radius where a corner would be.

All for the mill

Two APKT type insert cutters, one radius cutter, one bull nose and lastly a 45deg for truing your lathe tailstock etc or a counter sink

As Dave says.

Yes or more likely to machine a curved surface either on a copy machine or cnc by of setting each pass by a small amount the rounded edge leaves many small scallops rather than steps that a square edges cutter would.

Thanks for all the replies.

Hi Steviegtr what diamiter is the radius cutter tip as I may have a tip spare from when I worked in the real world. They were used to cut out cavities in mould tools, in pre-hardened steel, for the plastic industry. On a CNC mill they ran at high spindle speed and feed but only moved over a small amount to create a fair finish. If it fits your holder you are welcome to it.These are 16mm diamiter

Hi Dave I will check later. Just out at bikers cafe with mates.

Thanks for the offer.

They look quite dangerous to me. Send them here immediately for safe disposal.

Yes David indeed they are 16mm. I will gladly pay for the item & the postage if you want me to send you a P.M
