Versatile, easy to use
Use the Micro-Limit on virtually any type of shop equipment. No special operator skills are required.
Quick and easy adjustment
Adjustments are made by hand-indexing the castellated adjustment collar to control the depth of cut. Adjustment is in increments of .001 inch (.025mm).
Speeds and feeds
Use approximately the same speed and feed rate as with a standard HSS drill. However, the greater the depth of cut, the slower the speed required to avoid chatter.
For long tool life, the Micro-Limit should be kept free of grit, chips, and foreign matter. The countersink should be replaced when the cutting edges become dull. Loosen the set screw in the side of the countersink to remove the pilot. Unscrew the countersink to remove it from the drive spindle, and replace with a new one.
