1 Patentni zahtevki Sveder za izdelavo izvrtin s spodrezanjem v ometu, katerega glava obsega bočni rezili, štrleči s strani čez steblo svedra, in na steblu svedra zasnovan ovratnik, čez katerega je prosto vrtljivo poveznjeno globinsko omejevalo, značilen po tem, daje na steblu svedra med glavo (5) svedra in globinskim omejevalom (10) zasnovana izboklina (8) za tvorbo nihalnega ležaja, pri čemer globinsko omejevalo (10) obsega elastičen, obročast dušilni element (4), nalegajoč na ležajno podložko (3), ki se opira na ovratnik (2), zasnovan na steblu svedra. Sveder po zahtevku 1, značilen po tem, da je dušilnemu elementu (4) priključeno prek ovratnika (2) segajoče ohišje (15, 18). Sveder po zahtevku 2, značilen po tem, da ohišje (15) obdaja dušilni element (4) in ovratnik (2). Sveder po zahtevku 2, značilen po tem, da ohišje (18) s strani prijemlje v dušilni element (4), tako da spodnji, proti glavi (5) svedra obrnjeni del dušilnega elementa (4) prosto štrli iz ohišja (18). Sveder po zahtevku 1, značilen po tem, da globinsko omejevalo (10) obsega elastičen, lončast dušilni element (20), ki s svojo stransko steno (27) sega preko ovratnika (21), zasnovanega na steblu svedra, in ima dno (22) s skoznjo odprtino (24), skozi katero sega od ovratnika (21) do glave (26) svedra segajoče steblo svedra. Sveder po zahtevku 5, značilen po tem, da ima dušilni element (20) obris prisekanega stožca. Sveder po enem od zahtevkov 5 ali 6, značilen po tem, da imata notranja stena dušilnega elementa (20) in oblika ovratnika (21) konični obodni površini. Sveder po zahtevku 7, značilen po tem, da je ležajna podložka (23) uležajena med dnom (22) dušilnega elementa (20) in ovratnikom (21).1 Patent claims A drill bitsman with a plunging in a plaster whose head comprises side blades protruding from the side of the drill stem and a collar formed over the stem of the drill, across which a free rotation of the depth limiter is freely rotated, characterized in that the drill bit the drill head (5) and the depth limiter (10) are designed to form a pivot bearing (8), wherein the depth limiter (10) comprises an elastic, annular damping element (4) enclosing a bearing washer (3) collar (2), based on the drill stem. A saw as claimed in claim 1, characterized in that the housing (4, 4) is coupled by the collar (2) extending housing (15, 18). The saw according to claim 2, characterized in that the housing (15) is enclosed by the damping element (4) and the collar (2). The saw according to claim 2, characterized in that the housing (18) engages in the damping element (4) by the side, so that the curved part of the damping element (4) protrudes from the housing (18) downwardly towards the drill head (5). The saw according to claim 1, characterized in that the depth limiter (10) comprises an elastic, pot-shaped damping element (20) extending through its collar (21) with a side wall (27), and having a bottom (22 ) with a through aperture (24) through which the stem of the drill extends from the collar (21) to the drill head (26). The saw according to claim 5, characterized in that the damping element (20) has a contour of the truncated cone. The saw according to one of claims 5 or 6, characterized in that the inner wall of the damping element (20) and the shape of the collar (21) have a conical circumferential surface. The saw according to claim 7, characterized in that the bearing washer (23) is mounted between the bottom (22) of the damping element (20) and the collar (21).
