Deburring tool for deburring the edges of boreholes
First Claim
1. Deburring tool for deburring the edges of boreholes, comprising a base body (1) in which there is at least one recess (9) running across the longitudinal axis of the base body, at least one blade (8) mounted in said recess to be displaced rectilinearly under spring load in the longitudinal direction of the recess (9), a spring (5) mounted in a longitudinal borehole in the base body (1) and in contact with one end of a control pin, (7) the control pin having an other end engaging in a control recess (10) in the blade, (8) the control recess having a sloping camming surface whereby the said other end exerts on the blade (8) at least a holding force in the direction of displacement (20, 20'"'"').

Abstract
A deburring tool for deburring the edges of boreholes. The tool has a base body in which at least one recess aligned across the longitudinal axis of the base body is provided, where at least one blade is arranged in said recess so it can be displaced under spring load in the longitudinal direction of the recess. A compression spring is provided in the longitudinal bore of the base body and comes in contact with one end of a control pin whose other end engages in a control recess in the blade to provide at least a holding power to the blade in the direction of displacement.

6. A blade for a deburring tool for deburring the edges of boreholes, the tool having a base body in which there is at least one recess running across the longitudinal axis thereof, said base body having a longitudinal bore therein with a spring loaded control pin therein, said control pin having an axis, said blade comprising:
-
a radius from which extends a first straight line at an inclination of said axis of said control pin, followed by a second straight line having a lower slope than said first straight line; said blade being shaped and configured to be slidably received in said recess in said base body, its position being controlled by the position of said control pin with respect to said radius and said first and second straight lines in said blade. - View Dependent Claims (7, 8, 9, 10, 11)
