4-cutting edge insert knife describes a compact cutter that presents four usable edges, so each indexed turn places a fresh edge in the cut and keeps the tool body in service longer. This insert knife is identified as a straight insert CNC replacement knife, so it is meant to restore cutting performance on compatible CNC tooling without changing the core setup. The size is 10.5 mm x 10.5 mm x 1.5 mm, which defines the square profile and thickness that seat correctly in a matching pocket. The knife is designed for use with RC-2247, so it fits that tool body geometry to maintain proper cutting circle and balance. The product is classified as a bits and blades accessory and replacement part, which positions it as a service component in a tooling system rather than a stand-alone cutter.
The 10.5 mm x 10.5 mm x 1.5 mm dimensions define how this insert knife seats in a cutter body pocket, which affects clamping contact and edge projection. The straight insert CNC replacement knife description signals that the edge is arranged for straight cutting paths common in CNC routing, so the geometry aligns with that cutting style. Because it is specified for RC-2247, the insert knife matches that tool's insert pocket layout, helping maintain the designed cutting diameter and balance when replaced. As a replacement part within bits and blades accessories and replacement parts, it functions as a service item used whenever an existing RC-2247 knife edge has been rotated through all four positions.
The straight insert CNC replacement knife description indicates this insert is used on CNC machinery where the cutter body accepts straight inserts instead of brazed tips, so the knife supports repeatable routing operations on that platform. Its 10.5 mm x 10.5 mm x 1.5 mm size suits cutter heads designed around that exact square and thickness, so in use the edge height and projection align with the original tool design. Being for RC-2247 directly links it to that named cutter body, so anyone running that tool can match the reference and put the same style insert back into service. As part of bits and blades accessories and replacement parts, the knife functions in shops that maintain cutting performance by periodically changing inserts instead of replacing complete tools, supporting that maintenance workflow.
The 4 cutting edges on this insert knife provide four usable sides on one piece, so an operator can rotate the insert through several indexed positions before discarding it. That design helps extend the operating life of the RC-2247 cutter body, because only the insert knife, not the full head, is changed as edges wear. The straight insert CNC replacement knife format keeps geometry consistent each time a fresh edge is rotated into position, so the cutter behavior remains similar across rotations. The 10.5 mm x 10.5 mm x 1.5 mm format also ensures that each edge sits at the same distance from the pocket center when turned, so cutting depth relative to the tool body stays aligned with the original design through all four edges.
This insert knife is specified for RC-2247, so it matches that cutter body's insert pockets and supports maintaining the designed cutting geometry on that tool.
This insert knife measures 10.5 mm x 10.5 mm x 1.5 mm, so it fits cutter heads built around that square size and thickness for proper seating and edge projection.
This insert knife has 4 cutting edges, allowing multiple indexed rotations on the same piece so the RC-2247 tool body can remain in service longer.
The knife is described as a straight insert CNC replacement knife, so it supports straight cutting applications on CNC tooling that uses this style of insert.
This item is listed under bits and blades accessories and replacement parts, positioning it as a service insert within a larger cutting assembly.
This insert knife is from Amana Tool, aligning it with that manufacturer's RC-2247 cutter system and part numbering.
The 10.5 mm x 10.5 mm x 1.5 mm 4-cutting edge insert knife for RC-2247 provides a defined size and multi-edge format that match the described cutter body. For shops running the RC-2247 with straight insert CNC tooling, choosing this Amana Tool RCK-450 part restores the intended cutting geometry using the exact style of bits and blades accessory and replacement part specified.
