Re: Optimal Direction of the Drill and Chips

In support of Gary and Fotoplasma, the drills most definitely do not spin the same speed in reverse. The reason is the wind angle of the windings. They are biased by about 10 to 15 degrees in order to give better performance while drilling. You can tell when you operate an actual drill that the reverse is slower. There is great debate on these fori about if it matters that the speed is different. Our team thinks the difference is significant enough to make sure the drills are pointing in the same direction.

The CIM motors are close enough to the same speed that we have not done anything specifically to make sure they are pointing in the same direction.
