Abstract: Described is a multi-blade cutting and drilling finishing tool for machining deep or stepped bores. The tool comprises at least a first blade set having a nominal diameter and blades distributed essentially uniformly over the circumference. In order to make it easier to guide the tool along the central axis, a guiding strip set in the form of very accurately positioned cutting inserts is located axially behind the first blade set with respect to the axial direction of the tool in which the tool advances forward to machine the deep or stepped bores. Each of the cutting inserts is aligned with one of the blades of the first blade set in a direction parallel to an axis of the tool, and each of the cutting inserts has a nominal diameter which is smaller than the nominal diameter of the first blade set by essentially twice the size of a lubrication gap forming between the guiding strip set and the deep or stepped bores when the tool is used.

Abstract: The reaming tool (2) comprises a cutting part (8) having a peripherally arranged reaming cutter (10) which, upon rotation about a center axis (4) of the reaming tool (2), defines a cutting circle (16) of nominal diameter (D1). The reaming tool (2) further comprises at least two peripherally arranged guide elements (12A, 12B), which lie on a guide circle (18) arranged eccentrically to the center axis (4) or having a larger diameter (D2) than the cutting circle (16). As a result of this measure, high surface quality is obtained, in particular even in soft materials, since the reaming tool is clamped in the direction of the reaming cutter (10).

Abstract: Described is a multi-blade cutting and drilling finishing tool, in particular a reamer, for machining deep, especially stepped bores. Said tool comprises a set of blades having a predetermined nominal diameter and blades that are distributed in a substantially regular manner along the circumference. In order to make it easier to guide the tool along the central axis, a set of guiding strips in the form of very accurately placed and preferably cylindrically ground cutting inserts is located behind the set of blades in the advancing direction. Each of said cutting inserts is axially flush with the blades of the adjacent set of blades in the advancing direction of the tool and has a nominal diameter which is smaller than the nominal diameter of the set of blades substantially by twice the size of a lubrication gap forming when the tool is used.

Abstract: A reamer for finish machining a bore formed in a workpiece and method for providing a reamer with an abrasion resistant material. The reamer includes a body defining an outer surface, a cutting blade and guide member each coupled to the body, and an abrasion resistant material coupled to the reamer to form a friction resistant layer having a contact surface thereon. The abrasion resistant material impregnates the reamer to define an intermediate layer of abrasion resistant material intermixed with the reamer. The method includes the steps of assembling the reamer, applying an abrasion resistant material to said reamer, and allowing the abrasion resistant material to impregnate the reamer to define an intermediate layer of abrasion resistant material intermixed with the reamer.

Abstract: The operating life of the two guide members in a single bit reamer is increased by shaping the peripheral surface of the guide members with a radius of curvature less than the radius of the bore being machined. Contact between each guide member and the bore wall takes place only along a central quest area extending in the lengthwise direction of each guide member. This allows coating of the peripheral surfaces of the guide members with a hard, wear resistant material. Further, the guide members may be fastened to the cutter head by means of a screw situated in a groove extending in the tangential direction along the peripheral surface of each guide member. This increases the lubricating and cooling effect.
