Abstract A reaming tool comprising a reaming cutter with opposed cutting edges and a toolholder with a slot or lateral through aperture for the reception of the cutter. The holder has retaining means which act to retain the cutter within the slot or aperture with a limited degree of float radially of the reaming axis and generally in the plane containing the cutting edges, the float being in the form of guided sliding movement of the cutter within the slot or aperture.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
68 words
A reaming tool comprising a toolholder, a reaming cutter of generally disklike form with opposed cutting edges and mounted on the toolholder so as to project on diametrically opposite sides thereof with a diameter of the cutter parallel with the reaming axis, and retainIng and locating means for the holder which provide angular location of the cutter while permitting the latter to float radially of the reaming axis.
Claim 2
Dependent Claim
68 words
A reaming tool comprising a toolholder, a reaming cutter of generally disklike form with opposed cutting edges and mounted on the toolholder so as to project on diametrically opposite sides thereof with a diameter of the cutter parallel with the reaming axis, and retainIng and locating means for the holder which provide angular location of the cutter while permitting the latter to float radially of the reaming axis.
Claim 3
Dependent Claim
33 words
A reaming tool according to claim 1, wherein the cutter has locating means which enable the cutter to be mounted in the holder in any one of a plurality of different angular positions.
Claim 4
Dependent Claim
26 words
A reaming tool according to claim 1, wherein the locating means comprise a plurality of angularly spaced diametral grooves in one radial face of the cutter.
Claim 5
Dependent Claim
26 words
A reaming tool according to claim 1, wherein two halves of the outer periphery of the cutter are respectively ground to provide two semicircular cutting edges.
Claim 6
Dependent Claim

Claim 7
Dependent Claim
75 words
A reaming tool according to claim 1, wherein said location means comprise a location plate mounted between the cutter disk and the toolholder and having on the one hand a slot and guide rib engagement with the latter to guide radial floating movement of the cutter and, on the other hand, a peg and hole connection with the cutter whereby to locate the cutter angularly in a selected one of a plurality of angular positions.
Claim 8
Dependent Claim
56 words
A reaming tool according to claim 6, wherein said location plate is formed with a single diametral slot engaged by said guide rib which is formed on the toolholder, and the location plate is also formed with a plurality of holes selectively engageable by a peg projecting from the adjacent side face of the cutter disk.
Claim 9
Dependent Claim
23 words
