Drill head with carbide cutting edges, center and hexagonal socket (not for SDS-Quick chuck and others.), Drill diameter 60 mm.
As cutting head for a clean holes in (reinforced) finish coats of thermal insulation systems, for the assembly of wall holders with modular supporting bodies (WM 12XXX series). The insulating material lying under the plaster can also be gradually cut out cylindrically or gouged out with a knife. In mineral wool , only the final coat is necessarily pierced and then the insulation is pushed away sideways from the opening. Please use, if necessary, the general information about our tools available.
Use the centered drill at the marked site and make the cut with a low to medium speed and without percussion. After the initial setup, the 'scratching' of the drill bit may still shift the imprint and the position of the drill but drill bit position is easily corrected (photo). Then quickly drill into the depths. The head cuts up to 60 mm depth. The capped insulation (z. B. Styrofoam) is then broken, then the cylinder saw can set in insulating material thicknesses 60 mm again, further insulation is cut free and be broken again. The actual hole for securing the respective anchor rod in the supporting wall surface is usually made separately with hammer bit SB 16400, at concrete behind the insulation with hammer drill bit HB 16310. For more information, see the explanatory note to the distance system.
The shaft needs a conventional three-jaw chuck, which is tightened with the chuck or with a manual clamping ring. In other drill chucks, a secure hold is not always guaranteed. Please check if necessary, the safe, secure fit of the crown in the chuck before beginning to work.
