Features
Hinge Borers & Dedicated Drilling Machines — structure and configuration
Hinge bores
Several heads bore at once so hinge holes in doors are finished in one pass, with positions set by the frame.
Hole pitch
Hole pitches follow the 32 / 64 series, covering common hinge, handle and shelf holes.
Top-bottom centre
Centre-boring models cut from above and below at once so the two faces stay coaxial, with no second set-up.
