Friction and vertical cutting tool

Abstract

The invention relates to a friction and sinking cutting tool comprising a base member (2) to which a cutting blade (20) is exchangeably clampingly fixed by means of a clamping screw and which is adjustable in terms of its radial position by an adjusting member (40) through the intermediary of an adjusting means (30). The adjusting means (30) is a cutting blade carrier extending into a recess in the base member, and the adjusting member (40) is a differential screw which is in threaded engagement with the adjusting means. Alternatively, the adjusting means (30) can be a cutting blade carrier extending into a recess of the base member and the adjusting member (40) can be a ball member or clamping member which has automatic shape fitting engagement with a complementary recess in the adjusting means such that a movement of the adjustment member causes a movement of the cutting blade (20) in the same direction. It is advantageous if at least one bore for coolant is provided leading to the cutting zone, with at least one branch bore (22) leading outwardly from the forward region of the coolant bore. With this construction coolant and lubricant can be supplied to the cutting zone.
