Thats where i bought mine from in the thread `another rotary table question`. They seem ok quality from my `almost zero experience` but the hole seems a touch loose on my arbor despite both supposedly being 1". Cant remember whether its my arbor or the cutter bore that`s slightly off.

I recently bought a standard 16 DP 1 inch bore cutter (maker HBM) from them to cut some inserted steel teeth in a 70 tooth change wheel.

​It fitted my arbour without shake and ran dead true, the whole cutter doing it's job.

I have had examples of Chinese cutters that run off centre from the bore with an orbital action so that roughly half the cutter teeth actually do any cutting. The shape of the wheel teeth generated on the job is still correct, but there is a distinctly unfair bias on parts of the cutter as a result.

​Being hardened HSS I'm not sure if any correction can be made

What range of tooth count? It soon becomes more economical to buy a complete set from China. I am guessing RDG just buy in cheaply from China and then seriously hike the price. I recently bought a 16DP set from China, but have yet to use them, so cannot commentvon the quality. As far as I see it, careful cutting, well cooled, and cutting in not too hard a material will help them last a lifetime.

I found prices (and descriptions) from suppliers was not all it could be. Many pics were clearly of the same origin but with widely varied prices (for the same thing?).

At least RDG is UK based, so any complaints should be sorted easily.

I just used an RDG 32DP 14.5PA cutter to make a 60T steel gear for a dividing head I'm making and it worked just fine. Seemed to me to be a good quality cutter with no problems. I couldn't find that particular cutter anywhere else.

This is an Involute Gear Cutter from RDG, I'm using it on a shopmade arbour and didn't notice any eccentricity, maybe that was the reason..

The material being machined was En24T with coolant, worked extremely well, the wormbox gear is for my Son's Bantam.

PS there's a few more photos of this in my album….

I used RDG cutters to cut all the spur gears on my 6" Burrell traction engine, 6 DP, in both cast iron and steel gears, ………………..No problems at all,

I would definitely use RDG cutters again.

Have you got power on Z axis, if not that's a lot of handle turning !!!!

Emgee

Dunno about Richard, but a serious amount of handle w**king in my case; six gears times 72 teeth per gear, and 24 turns of the handle per tooth:

Hello Emgee,

On the Tos mill which I cut the final drive gear I have power feeds and rapids in all directions, saves a lot of handle winding.

Richard

Just be aware that if you get MJ to cut any of the gears they will be 20deg pa
