Operator’s Manual

CAUTION:

When used on a pressurized system an outward force on the 

shaft will occur as the drill bit passes through wall of the pipe. 

Forces can be as high as 45 lbs on a system pressurized at 300 

psi. At any time after the drill bit passes through wall of the pipe 

a reactive force must be applied to the end of the shaft until the 

shaft is in the fully retracted position, failure to do so my cause 

damage to the tool or personal injury.

 

Applying too much force while cutting the coupon can result 

in a sudden breakthrough of the hole saw. A sudden break 

through may result in the coupon retaining drill bit striking the 

back side of the main and damaging the drill bit. One can prevent 

this by cutting a spacer of 3/4” copper tube long enough to stop 

the drill bit from hitting the back of the main. Slip this spacer over 

the exposed shaft between the gland nut and the drill chuck.

Note: Use standard depth holes only.

Store shafts separate from hole saws.  Allowing the hole saw 

teeth to contact the shaft during transportation and storage can 

damage the shaft. A damaged shaft can damage the Main Body 

and cause the shaft to seize during use.
