FESTA INDUSTRY diamond core bits expand the product line designed primarily for professional use
Fast and precise cutting and long service life—depending on the type of material and technique!
Mounting: M14 thread for angle grinders or, with an adapter (22087), also for drills/cordless drills
For “dry or wet” precise and fast drilling/cutting in stone, hard paving stones, stoneware, tiles, granite, marble, and other extremely hard materials—not only in the construction industry
Diamond layer thickness: 10 mm; smaller diamond grain size and, consequently, higher diamond grain density; cooling wax or, for larger diameters, holes for faster cutting and significantly longer service life
No auxiliary tools required—drill a precise hole exactly where you need it
Recommended procedure -
Screw the drill bit directly onto the threaded shank of the angle grinder head and tighten securely.
Begin cutting the desired hole at a 45° angle; the core bit and the speed
will immediately secure the hole in the desired location; slowly and with even
pressure, straighten the cutting direction to a vertical position. Smaller diameters (6–12 mm) are filled with wax; for
extend the cutting ring’s service life, it is recommended to replenish the wax (24710), cool with water,
or allow it to cool with air while the machine is running!
