The annular cutter continues to be doing the identical factor, so I am beginning to think it may be the adapter...although I'm not sure how that would be. It drills fantastic with regular twist bits, just has trouble with the cutters. It is too lengthy and loses rigidity being chucked within the jaws of a typical drill chuck. If you happen to put an indicator on that cutter at it's leading edge, I bet you've got runout.

Even the shaft of the arbor is not very huge by the seems to be of it. The jaws of a drill chuck can only grip it to a sure degree. I've run annular cutters in a hougen drill particularly set up for them a pair instances, however have primarily run them in my mill, using an finish mill holder straight into my spindle. I would shop round for one in case you planned on using annular cutters regularly. I'm not an knowledgeable on these things, but every thing I'm seeing thus far leads me to imagine the arbor adapter simply isn't going to be rigid enough to handle the annular cutter. The half slightly below the drill motor slides up inside and is held in by the spanner nut.

You got plenty of length working in opposition to you with the shaft chucked within the drill chuck being the weakest point of contact. All that stuff provides up and as soon as the enamel of the cutter start taking a full load, you get the grabbing seemingly attributable to deflection and vibration. The pilot pin and spring SHOULD be kept in the annular cutter on this model particular style of mag drill.

The smaller diameter shaft of your arbor chucked in the Jacobs chuck jaws is likely vibrating as soon as underneath load, and I bet you've got some runout on the face of the cutter because HSS annular cutters of it. Drilling machines specifically designed for use with annular cutters also usually have a further support hooked up to the spindle to take care of optimal rigidity.
