DEEP HOLE DRILLING SOLUTIONS BY TOOLINGS
 
 
PULL REAMING / PULL BORING
 
Pull boring is being used mainly to have very straight and accurate long holes.
The oil is fed similar to BTA drilling or counter boring i.e. through the pressure head. The evacuation of chips and coolant can be from the front or through the drill tube.
As the drill tube is under tension during pull boring the enlarged bore produced is quite striaght.
There is another type of pull boring in which multiple cutting edges are being used. This has guide pads which are supported in the pre bore, thus producing the enlarged bore on the originial axis.
