Milling cutters?

[Bootlegger BlackyParticipant @bootleggerblacky]

Hi all. I was hoping someone could please tell me what make of milling machine these rather large tools fit?as per pictures.

Hoping to list these on eBay for prospective buyers.But unsure how to describe. I am open to offers.

I have also listed Stuart Turner 10v. Castings if anyone is interested?

Item number…236016503139

Thanks.

Looks like most of them are intended to be mounted on an arbor in a horizontal milling machine, some explanation here. May be some could be mounted on arbors like these:

(from ArcEurotrade), What diameter are the holes in the cutters?

Horizontal milling cutters catalogue for the serrated ones

[Andrew CrowParticipant @andrewcrow91475]

They are inserted tooth side and face cutters for use on a horizontal milling machine.

Once quite common in industry as they were cheaper to manufacture as only the teeth were made from HSS.

The other advantage was that the teeth could be replaced, a forerunner of the modern carbide tipped tooling.

Not a ‘make’ thing.  They’ll fit any horizontal milling machine with an arbour matching the centre hole diameter and keyway.  So put those measurements in the advert.  Value unpredictable.   Not many home workshops have horizontal mills, but someone might be hungry for them.

Side and face milling cutters with insert teeth,. The central hole will be either 1in or 1 1/4. the latter is rarely used by amateurs. It is important to mention central hole dia, overall dia, width in inches not mm.
They are not shell mills as used on the arbors mentioned by Thor above as those have notches for the two projections on the arbor.
Once the width exceeds the diameter with no end teeth they are generally known as slab mills.
Since so few people use them the value is about half the cost of shipping. I only buy them at shows to avoid the shipping cost. Also as they are intended mostly for removing metal in bulk I can’t afford to be turning that much metal into swarf.

I have a horizontal milling machine that has the power and rigidity to make use of the pictured serrated insert cutters, but I already have a shelf full of horizontal milling cutters. So the auction price is coming on for an order of magnitude more than I’d be willing to pay. I would also need to know all bore sizes as I have a full range of imperial arbors but a limited range of metric arbors.

As with all items their worth is what someone is prepared to pay.

I was in production machine shops since the mid nineteen-sixties, and I’ve never seen inserted tooth side and face cutters in that form before.

I would suggest that they are production tooling from as early as WW2.

A fiver each if you are lucky.

Howard, they are still made, see my link.

Not sure I would want to use them, serrated type woodworking cutters were banned quite a while ago but they did tend to be run a lot faster in a spindle moulder so maybe that was why the cutters flew out the block.

I had a look at the link of yours, fitting the blades:-

“using a copper hammer only, take care not to strike the cutting edge, as this may cause
chipping of the blades”

Amazing.

[BazyleParticipant @bazyle]

By the way if listing on any sale site don’t just slap a rule in the general vicinity of the product and assume people can read it. Make the effort to measure each item and list it, preferably in the title for search engines.

These cutters should be run at a few hundred RPM only for metal so all this talk of centrifugal forces and inserts coming out is tosh. It is also a problem that most hobby size horizontals can’t go slow enough for a cutter of 4in dia.

Thor meant to link to this 

Though sideways cutting forces makes workholding harder.

[BazyleParticipant @bazyle]

Thanks Dave – that is annoyingly tempting.

[Mark EasingwoodParticipant @markeasingwood33578]

Just for info;

The serrated back cutters used in woodworking machinery have the serrations at 90 deg to those milling cutters, so they can’t fly out and kill you.

They haven’t been banned, you can use them in a mechanically fed machine, i.e. a “four sider”.

You can still use them in a hand fed spindle moulder, so long as you use the, “Limiter Blocks & Cutters”, see here, Whitehill. I run them at 6000 rpm.

There are a lot of illeagal and downright dangerous woodworking cutters and blocks for sale on Ebay & Facebook market place.

Mark.
