Boring tool guide device

A boring tool guide and positioning device comprising;

• clamping means having opposed jaws, said boring tool device being secured in one of said jaws substantially perpendicular to the surface of a work piece engaged by said clamping means, a cutter shank having a cutter at one end and means for connecting the shank to drive means at the other end, a guide body, said guide body including a base portion having an axial bore, and a tubular portion extending axially from said base portion and being substantially coaxial with said bore, a tubular shaped depth control spacer having a end wall and an axial aperture therein, said control spacer being in telescoping engagement with said tubular portion, said control spacer having means for limiting the distance that the tubular portion of the guide body can be telescoped therein, resilient means received within said tubular portion and control spacer to bias the control spacer and the guide body axially apart, said cutter shank being guidingly received in the axial bore of said guide and the cutter and the connecting means extending beyond the guide body and control spacer respectively, whereby said clamping means can be secured to the work piece and said drive means can be removably secured to said connecting means to axially feed the cutter along its axis into said workpiece with the maximum depth of penetration being determined by said limiting means.
