Claim:
A portable power angle grinder, comprising: a motor housing ( 22 a , 22 b , 22 c , 22 d , 68 ; a housing cover ( 26 a , 26 b , 26 c , 26 d , 72 ) attached to the motor housing ( 22 a , 22 b , 22 c , 22 d , 68 ) by sliding the housing cover in an axial direction onto the motor housing; an insulation means ( 44 a , 44 b , 44 c , 44 d , 70 a , 70 b ); and a guide means ( 50 a , 50 b , 50 c , 50 d , 52 a , 52 b , 52 d , 92 ), wherein said insulation means ( 44 a , 44 b , 44 c , 44 d ; 70 a , 70 b ) abuts on said motor housing ( 22 a , 22 b , 22 c , 22 d , 68 ) and on said housing cover ( 26 a , 26 b , 26 c , 26 d , 72 ), wherein said insulation means ( 44 a , 44 b , 44 c , 44 d , 70 a , 70 b ) is guided via said guide means ( 50 a , 50 b , 50 c , 50 d , 52 a , 52 b , 92 ) toward the motor housing ( 22 a , 22 b , 22 c , 22 d , 68 ), the housing cover ( 26 a , 26 b , 26 c , 26 d , 72 ), or both said motor housing ( 22 a , 22 b , 22 c , 22 d , 68 ) and housing cover ( 26 a , 26 b , 26 c , 26 d , 72 ), wherein a contact surface of said insulation means abuts on a contact surface of said guide means, wherein said guide means ( 50 a , 50 b , 50 c , 50 d , 52 a , 52 b , 52 d , 92 ) is provided to prevent a displacement of the contact surface of said insulation means ( 44 a , 44 b , 44 c , 44 d , 70 a , 70 b ) relative to the contact surface of said guide means in an axial direction when said housing cover ( 26 a , 26 b , 26 c , 26 d , 72 ) is slid in an axial direction onto said motor housing ( 22 a , 22 b , 22 c , 22 d , 68 ), and wherein the housing cover is shaped like a cup and is attached to the motor housing in the axial direction; wherein said insulation means as a whole is located exclusively radially between said motor housing and said housing cover, and said guide means have no components extending radially and preventing a sliding of the housing cover onto the motor housing in the axial direction.
