An improvement to a surface burring tool comprising the use of drive pins each with flat surfaces, the first flat surface to bear on the flat surfaces of the angled ramps of the tool body so as to reduce pressure and to thereby reduce wear, and the second flat surface to locate against an edge of the slot in the retaining clip of the blade assembly to prevent rotation of the pin. This will ensure that the first flat will be parallel to its ramp on insertion of the replaceable blade assembly into the tool body. Pin rotation might result in the first flat not remaining parallel the tool ramp on which the pin slides during tool operation.
Une amélioration est apportée à un outil débarbage de surface comprenant lutilisation dergots dentraînement avec des surfaces planes, la première surface plane reposant sur les surfaces planes des rampes inclinées du corps de loutil de manière à réduire la pression et, par conséquent, à réduire lusure. La deuxième surface plane repose contre un bord de la fente dans lélément de retenue de lensemble de lame afin déviter la rotation de lergot. Cela permettra de sassurer que la première surface plane sera parallèle à sa rampe au moment de linsertion de lensemble de lame remplaçable dans le corps de loutil. Une rotation de lergot pourrait faire en sorte que la première surface plane ne demeure pas parallèle à la rampe de loutil sur laquelle glisse lergot durant le fonctionnement de loutil.
