Patent number: 6032749Abstract: A drilling tool has a shank (1) at one end, a shaft (2) with two helical grooves (5, 6) and the shaft (2) extends from the shank to the other end of the drilling tool. A drill head (8), with a cutting plate (7) inserted in it, is located at the opposite end of the shaft (2) from the shank (1). The cutting plate (7) has a cutting tip (74) projecting axially outwardly from the drill head (8). The cutting plate has a dimension (B) extending perpendicularly to the axis of the drilling tool and the dimension (B) is greater than the diameter of the drill head (8). On the opposite sides of the cutting plate (7) there is a reinforcement section (71) projecting outwardly from the side of the cutting plate and spaced laterally from the ends of the grooves (5, 6) in the drill head.Type: GrantFiled: December 5, 1997Date of Patent: March 7, 2000Assignee: Hilti AktiengesellschaftInventors: Hans-Werner Bongers-Ambrosius, Rainer Batliner, Dietmar Sartor, Harald Geiger, Anton Knoller

Patent number: 5553682Abstract: A rock drill includes an axially elongated shank with a chucking shank part (1) at one end, a drilling shank part (2) extending from the chucking shank part and having at least four drilled material conveying flutes (4, 5, 6, 7) disposed next to one another in a parallel manner, and a drilling head at the opposite end of the shank and formed of hard metal and having four removal flutes (8, 9, 10, 11) spaced apart about its outer circumferential surface. The removal flutes have transverse cross-section of different size and each of the transverse cross-sections of the removal flutes (8, 9, 10, 11) open into one of the conveying flutes (4, 5, 6, 7) of the drilling shank part.Type: GrantFiled: June 7, 1995Date of Patent: September 10, 1996Assignee: Hilti AktiengesellschaftInventors: Rainer Batliner, Anton Knoller, Axel Neukirchen

Patent number: 5492187Abstract: A rock drill has an axially elongated shank (1) with a hard metal drill head (2) secured at one end. The transverse cross-section of the drill head is basically rectangular with cutters located along each of two diagonals of its cross-section. The cutters remove drillings from rock. The cutters include a main cutter (4) and two auxiliary cutters (5, 6) having the same rotational envelope curve.Type: GrantFiled: November 18, 1994Date of Patent: February 20, 1996Assignee: Hilti AktiengesellschaftInventors: Axel Neukirchen, Rainer Batliner, Maximilian Stock, Ralf Baumann

Patent number: 5345997Abstract: A cooling device (1) in the form of a vertically arranged hollow chamber is located between a heat treatment furnace (9) and a quenching bath (11d). The device controls the cooling of small hardware items dropping downwardly through it from the furnace (9) to the bath (11d). Spaced baffles (3) are arranged in the hollow chamber and are adjustably inclinable relative to the vertical. A heat transfer member is connected to the baffles so that heat can be removed from or stabilized in the small hardware items flowing over the baffles.Type: GrantFiled: December 17, 1993Date of Patent: September 13, 1994Assignee: Hilti AktiengesellschaftInventors: Eckart Drossler, Rainer Batliner

Patent number: 5172780Abstract: Precipitation hardenable solders are used for securing hard metal or hard material parts to the support member of a tool for drilling, chipping or cutting rock or hard construction materials. The support member is formed of steel. The hard metal or hard material parts are secured to the support member by soldering using a precipitation hardenable solder. The parts secured to the support member are subjected after a solution treatment to the tempering and precipitation hardening temperature.Type: GrantFiled: November 15, 1991Date of Patent: December 22, 1992Assignee: Hilti AktiengesellschaftInventors: Rainer Batliner, Maximilian Stock
