A striking mechanism includes a working space whose first section is surrounded by a first electromagnet and whose second section is surrounded by a second electromagnet; a striking element that can move along a striking axis inside the working space and that has a magnetizable material; an anvil whose striking surface delimits the working space in the striking direction and which protrudes into the first magnetic coil and which is made of a magnetically soft material. A spring element is provided which exerts a force onto the striking element in every position in the working space in the direction of the anvil.

Striking mechanism and hand-held power tool

An abrasive cutter formed of at least one diamond particle, preferably at least one mono-diamond crystal and metallic binder material distinguished by the fact that the diamond particle (D) has a size of about 50 &mgr;m to about 500 &mgr;m and each diamond particle (D) is enclosed by a coating (H) produced in a fluidized bed with the coating having a wall thickness of about 10 &mgr;m to about 200 &mgr;m. The volume of the coating (H) constitutes at least 30% of the volume of the diamond particles (D) in the fully consolidated state following individual sintering of the coated diamond particles (D, H). The abrasive cutters can be applied directly onto an abrasive tool. Further they can be processed to form composite cutters or cutting segments. In the method of forming the abrasive cutter, the diamond particle (D) is brought into a fluidized bed reactor and enclosed in a metallic coating (H). Coated diamond particle (D, H) can be processed into larger cutters or segments in each case individually sintered and fixed directly on an abrasive tool.

A composite cutting tool for use in the abrasive processing of hard substrates comprising cutting elements wherein diamond particles in a predominantly metallic binder material are agglomerated and sintered during an individual molding process of each of said cutting elements.

A grinding tool bit is formed of a disk-shaped base member (1) with a central through opening (6) for attaching the base member to a drive spindle of a machine tool. The base member (1) is covered with individual cutting elements (4) at the radially outer circumferential surface (2) and in the side faces (3) adjacent the outer circumferential surface (2).
