Annular part does all the work so small cutting resistance reduces drilling time
Cutting of slanted, elongated and edge holes is now possible
Fractional and metric cutter sizes to suit wide range of applications
Produces little slag and few chips for easy disposal
Can also be fitted to and used with previous Atra Ace models using a hexagon socket set-screw
Cuts holes three times faster than conventional twist drills
Minimal cutting resistance reduces cutting time
Improved concentricity extends cutter life! One-touch system consisting of three balls inside the arbor body produces a self-centering effect during cutting to improve cutter performance and life
