What is a power screw specification?
It is a double-headed screw that connects the cutter and arbor.
The cap screw for general cutters is screwed and fixed only on the arbor side, but it is also screwed on the cutter side.
In addition, since the counterboring hole of the cap screw head is not required, even a small-diameter cutter can be fixed more firmly without compromising the wall thickness.
How to use the power screw
・The power screw does not require a counter bore even with a small-diameter shell-type cutter, so high body rigidity can be ensured.
• 3 times the clamping force compared to standard cap screws
Applicable cutter: PSEφ40,50 PHCφ40 PAOφ50 PRC16φ50

2. Carefully turn it to the part where the power screw stops.

4. Final tightening (zero gap) is performed with a hex wrench.
