Abstract: A modular rotary cutting tool includes a cutting head for insertion into a support. The cutting head has a coupling pin having torque surfaces and clamping surfaces formed on its outer peripheral surface. The coupling pin is divided into a front pin part and a rear pin part. The front pin part is defined by a circumferential groove. Stop surfaces for an axial pullout prevention are formed between the front pin part and the rear pin part. The torque surfaces and the clamping surfaces are arranged in different pin parts. For example, the clamping surfaces are preferably formed on the front pin part and the torque surfaces are preferably formed on the rear pin part. The clamping surfaces taper radially inward in a direction of the front cutting part at an angle of inclination, α2, with respect to the axis of rotation. Other variants and embodiments are broadly contemplated herein.

Abstract: A front-loaded, side-activated modular drill includes a shank and a replaceable cutting insert installed on and engaging the tool shank. The shank has a pocket for supporting the cutting insert when the cutting insert is installed within the pocket. The pocket includes a first centering wall having an aperture with internal threads formed with a first pitch and a second centering wall having an aperture with a first portion with internal threads formed with a second, different pitch. A first member is threaded into the aperture of the first centering wall, and a second member is threaded into the second centering wall. The first member is threaded into the second member. The cutting insert has an opening in a trailing end for allowing the first member to pass therethrough. Rotation of the first member causes the centering walls to elastically deform and move relative to each other.

Abstract: A collet includes an axially rearward end and an axially forward end; a nose portion; a body portion having an outer surface and an inner surface for engaging a shank of a tool; a plurality of slots extending from the inner surface to the outer surface; and a plurality of coolant channels disposed within the collet between the plurality of longitudinally extending slots and extending entirely from the axially rearward end to the axially forward end of the collet. The slots include a first slot extending from the axial forward end to within an intermediary zone, a second slot extending from the axial rearward end to at least the tool holder engagement zone such that the second slot does not intersect the first slot, and a third slot from within the tool engagement zone to within the intermediary zone such that the third slot circumferentially overlaps the first and second slots.

Abstract: A cutting head is formed for insertion into a support in a modular rotary tool, in particular a drill. The coupling head has a coupling having torque surfaces and clamping surfaces on its outer periphery. The coupling pin is divided into a front pin part and a rear pin part. The front pin part is defined by a circumferential groove. Stop surfaces for an axial pullout safety are formed in the transition area between the two the front pin part and the rear pin part. The torque surfaces and the clamping surfaces are arranged in different pin parts. For example, the clamping surfaces are preferably formed on the front pin part and the torque surfaces are preferably formed in the rear pin part.

Abstract: A toolholder connector having one threaded end and one end with a male quick change portion is threadingly engaged with a first toolholder having a threaded bore. The quick change connector also has a male quick change portion that is engaged within a side activated receiver of a second toolholder. Prior to activating the receiver, an alignment pin associated with the first toolholder is lined up with alignment slot associated with the second toolholder such that when the two are brought together, a pre-determined radial alignment will be retained.
