Key Features
Cammed-lug release helps prevent penetration.
Pre-tested for quality and reliability.
Controlled drilling without premature release.
Non-skid tip for stable positioning.
Precision cutting with less pressure.
Available in multiple size options.
Automatic release at bone thicknesses below 1 mm.
Bone pad helps protect the dura.
ACRA-CUT perforators create a
bone pad for added dura protection.

Cut-away view of the
ACRA-CUT automatic release mechanism.
The inner drill cammed-lug is shown in the drive position during perforation.
The cammed action responds to a sudden drop in bone resistance, allowing the inner drill to shift forward by less than 1 mm, disengaging the clutch and immediately stopping further cutting.
Product Information
