Publication number: 20230311289Abstract: A hammer drill having an impact mechanism and a rotary drive, wherein the hammer drill is designed to rotate a tool at a speed n about a longitudinal axis of the tool and to drive it with an output impact power PS along the longitudinal axis with a striking movement is disclosed. At a working point, at least one condition is met: 1. The ratio of the output impact power PS to the speed n is at least 3.5 W/rpm; 2. Depending on the output impact power PS, the speed n is at most (PSAN?300)2/2000+150) rpm; 3. In the event of an infinitesimal change in the output impact power PS, the speed n changes by at most 0.1 rpm/W.Type: ApplicationFiled: February 22, 2021Publication date: October 5, 2023Inventors: Maximilian KNYRIM, Markus HARTMANN, Bastian PLÜMACHER, Olaf KOCH

Publication number: 20230278182Abstract: A hand-held power tool includes a tool fitting, an impact mechanism, and a rotary drive. The hand-held power tool is configured to rotate a tool held in the tool fitting with a rotational speed about a longitudinal axis of the tool and to drive the tool with an impact movement along the longitudinal axis at an impact frequency f. A ratio of the rotational speed to the impact frequency f at least at a working point of the hand-held power tool is at most 5.0 rpm/Hz or at least at the working point of the hand-held power tool the rotational speed is at most (0.2*(f/Hz-22){circumflex over (?)}2+80) rpm for impact frequencies f in a range from 20 to 60 Hz.Type: ApplicationFiled: February 22, 2021Publication date: September 7, 2023Inventors: Maximilian KNYRIM, Markus HARTMANN, Bastian PLÜMACHER, Olaf KOCH

Patent number: 11338425Abstract: Control method for a dust extraction module (2) for a chiseling tool (5), including the following steps: using a fan (18) of the dust extraction module (2) to draw in an air flow Q from a certain place of a substrate (31) being worked by the tool (5), using a material detector (24) to identify the material M at the place of the substrate being worked by the tool (5), and adapting the suction power of the dust extraction module (2) as a function of the identified material M in order to set the air flow Q. The air flow Q is greater than or equal to a rated value Qo in the case of an iron-free mineral material M1, whereas the air flow Q is less than the rated value Qo in the case of a material M2 containing iron.Type: GrantFiled: October 17, 2017Date of Patent: May 24, 2022Assignee: Hilti AktiengesellschaftInventors: Markus Hartmann, Klaus-Peter Bohn, Bastian Pluemacher, Thilo Hammers, Michael Brunner

Patent number: 10947788Abstract: A drill bit that serves to remove mineral materials and that consecutively has on a longitudinal axis (6) a drill head (2), a helix (3), an insertion end (4) and an impact surface (7) on the end face of the insertion end (4) that faces away from the drill head (2) and that serves to absorb impact along a direction of impact (8), is provided. The drill head (2) has at least two cutting edges (13) and at least two blades (20). The cutting edges (13) each have a cutting face (16) and a free face (17). The blades (20) run parallel to the longitudinal axis (6) and adjoin the cutting edges (13). The blades (20) each have a radially projecting tooth (24) that adjoins the cutting face (16), whereas it adjoins the free face (17) either only partially or not at all. The axial dimension (29) of the tooth (24) is smaller than the axial dimension (25) of the blade (20).Type: GrantFiled: April 19, 2017Date of Patent: March 16, 2021Assignee: Hilti AktiengesellschaftInventors: Guenter Domani, Bastian Pluemacher, Roland Foser

Patent number: 10906166Abstract: A control method for a bore-chiseling portable power tool for machining a substrate by a drill bit includes superimposing a periodic striking on the drill bit at an impact rate and a rotating of the tool holder at a rotational speed in a rotational direction, identifying a material of the substrate being machined by the drill bit by a sensor, adjusting the rotational speed and/or the rotational direction to a first rotational speed and a first rotational direction when the identified material is an iron-based material, and adjusting the rotational speed and/or the rotational direction to a second rotational speed and a second rotational direction when the identified material is a mineral material. The first rotational speed is less than the second rotational speed and the first rotational direction is counter-clockwise and the second rotational direction is clockwise.Type: GrantFiled: December 6, 2016Date of Patent: February 2, 2021Assignee: Hilti AktiengesellschaftInventors: Carsten Peters, Helene Wesseler, Markus Hartmann, Klaus-Peter Bohn, Thilo Hammers, Bastian Pluemacher
