   I've only used a rosette cutter for a few hours. I did get tearout at first,then reduced the drillpress speed to about 300 rpm. This did the trick, no more tearout.

   Thanks, Mike. I have been using speeds as low as 260 up to 420. Same results.

   Dusty,
   I am using a one piece bit with a carbide tip on a 1/2" shank. The rosette cutter has a diameter of 1 3/4." I am also using this on a
   16" Floor Model Delta Drill Press. The speed range I've tried has been between 260 and 420. The tear out is occurring on the "inner" circle, outside the center button of the rosette.

   jayder,     

             Have you tried a softer or different wood just to see any change ?

           Did the cutter come with the manufacturers recommended  speed ?

         I would keep trying different speeds (faster perhaps) and also the feed rate could cause problems .

          Some rosette cutters are designed to run on the router at much higher speeds , could this be one of those .

         Is the area of question damaged or chipped or otherwise dull ?

       I had a rosette cutter made with a #2 Morse taper so I can use it on the lathe or the drill press , the cutter is interchangeable , so other profiles can be used . The cutter can be moved in and out to change the diameter of any given detail or profile .

          The first job I used it for was to reproduce some Bullseye Rosettes for a older home on the local historical register , being restored they needed to reproduce to original when possible .

                           good  luck            dusty

   Thank you for your help. It is a brand new cutter, but didn't come with instructions. I did try soft maple, slight improvement, but not much.
   I will vary the speeds on my drill press and see what happens.

   Here are a few things to try. If your DP has a lock lever / nut that takes up any excess play in the quill. Tighten it as tight as it can be and still allow for travel after you have lubricated the heck out of it. If this does not do it, try to make a hold-down block that has a zero-clearance hole for the cutter, so that it can't jump around while it is cycling between going with and then against the grain four times per cycle. Of course this will only work if there is a place for the chips to make it through.

   Just a thought. This works on difficult woods with irregular grain. Try wetting the wood down with a squirt bottle or wet rag. Let me know if this works.

   Thank you for your response. I did the rosettes before I saw your answer. I used the drill press at 300RPM, made sure everything was tightened down on the table, and used an extremely slow feed rate.
   That worked pretty well, but I will try your tip in the future!
   Thanks, again.
