Z3 Solid-TC Geometry
Three staggered solid-TC cutting edges are arranged in spiral form for the verified 20260 configuration.


JSO 20260-6-12040-R is the exact 12 mm solid-TC Z3 finishing cutter with 42 mm cutting length, 90 mm overall length, 12 mm shank, right-hand rotation/right-hand helix, mechanical feed, and JSO-XD coating.
Exact JSO/Titan configuration verified against the current manufacturer family record and the supplied Titan commerce SKU.
Confirm the exact 20260-6-12040-R Part-No., 12 mm shank, right-hand rotation, 42 mm cutting length, mechanical-feed application, and machine/toolholder limits before use.
JSO 20260-6-12040-R is the exact 12 mm member of the 20260 Z3 finishing-cutter family. The official catalogue row specifies D 12 mm, L2 42 mm, L1 90 mm, a 12 mm shank, and JSO-XD coating.
JSO describes the 20260/20261 family with three staggered solid-TC cutting edges in spiral form, ground and periphery cutting, right-hand rotation, right-hand helix, and mechanical feed.
The family is intended for grooving, jointing, finishing, and sizing wood and panel materials on CNC routers. Its inward-pulling cutting action is specifically described as supporting high edge quality on both sides.
Technical Specifications
Three staggered solid-TC cutting edges are arranged in spiral form for the verified 20260 configuration.
JSO describes the 20260/20261 family as cutting from outside toward the centre to support edge quality on both faces.
JSO-XD is the verified coating designation; the underlying active cutting material remains solid carbide.
Confirm the exact 20260-6-12040-R Part-No., 12 mm shank, right-hand rotation, 42 mm cutting length, mechanical-feed application, and machine/toolholder limits before use. Do not substitute a neighboring JSO row, hand, angle, coating, insert grade, screw size, or family simply because one or more dimensions appear similar.
JSO 20260-6-12040-R combines 12 mm diameter, 42 mm cutting length, 90 mm overall length, Z3 solid-TC geometry, right-hand helix, and JSO-XD coating.
The exact 20260 row must remain separate from neighboring diameters, cutting lengths, and the related 20261 configurations.
