pace. With experience, the operator will be able to determine the best pace to feed to the work. There  
should be some degree of audible slowing of the motor but not bogging in the cut. Correct cutting 
speed with a properly sharp annular cutter will produce long unbroken chips, which produce a “bird’s” 
nest. shaped bundle of chips around the cut. 
NOTE: Always ensure that the cutting tool is sharp. A dull cutter typically will have finer and/or choppy 
shavings.
WARNING: ALWAYS clear chips when there is too much build-up. Excessive chip build-up could result in 
a jammed cutter or other hazardous situation.
WARNING: the slug ejects at end of cut and is very hot. Always provide a method of catching the slug, 
where the ejected slug may cause injury to people below.
CAUTION: Never attempt to cut half-circles or to stitch drill (drill overlapping holes) with a TCT cutter. 
This may destroy the cutter.
CAUTION: Do not leave the magnet on for extended periods of time. This will lead to overheating of the 
coils and subsequent early failure. Only turn the magnet on when you are ready to drill and turn back 
off when you are done.
