14mm x 14mm x 2mm 4-Cutting Edge General Purpose Insert Knife gives you a compact cutter with four usable edges, so you can rotate the insert as edges wear and keep tooling running without changing the overall setup. The Amana Tool RCK-70 designation identifies this as an indexable replacement knife, which helps match it to existing Amana insert tooling in your shop. The general purpose insert knife format supports reuse in compatible cutter bodies, which keeps cut quality consistent on repeated jobs in the same tooling line. As a replacement part in the bits, blades and cutters category, it restores cutting performance to worn insert-based tools used in daily woodworking work.
The 14mm x 14mm x 2mm dimensions define the compact insert footprint, which sets how the knife nests in an insert pocket and maintains proper projection for consistent cutting paths. The 35 degree bevel on every knife fixes the cutting angle, which supports repeatable performance when replacing an existing RCK-70 knife in the same style body. As an indexable replacement knife, the RCK-70 format is meant to be rotated and swapped in matching insert-based tooling, which helps retain spindle height and fence positions between maintenance cycles.
The SAP description identifies this part as an indexable replacement knife, so it is intended for tools that are built around interchangeable inserts rather than brazed or solid cutters. The tool application listing ties this knife to insert straight bits RC-1080, RC-1082, RC-1154, RC-2080, RC-2082 and RC-2154, meaning it serves as the cutting edge in those specific straight bit bodies. The same knife is also specified for insert trim bits RC-1000, RC-1008, RC-1010, RC-1012, RC-1014, RC-1024, RC-1026, RC-2257 and RC-2258, which ties the insert directly to trimming operations in those router tools. In addition, the knife is called out for insert cutter heads 61288, 61292, 61340, 61360, 61362, 61460, 61462, 61470, 61472, 61480 and 61482, so it serves as the working edge in those cutter head assemblies on appropriate machinery.
The 4 cutting edge design means a single knife can be rotated four times, which spreads wear across all sides and keeps the same insert body in use longer for cost-effective maintenance. The 35 degree bevel establishes a consistent cutting geometry across all knives, which helps maintain similar feed feel and finish when swapping or rotating inserts in the same bit or cutter head series. The "G" 35 degree general purpose designation targets wood, chipboard and plywood, so this knife is intended to handle common shop sheet goods and lumber within that range. The note that new grades are available for softwood, hardwood, MDF, solid surface and micro-finish general purpose work shows that the insert family addresses varied material demands, allowing the same style of knife to match different substrates while retaining the indexable concept. Together, these details keep insert-based Amana bits and cutter heads operating within their intended performance window across routine production routing and trimming.
The RCK-70 is an indexable replacement knife with 4 cutting edges, so it functions as a replaceable insert in compatible Amana Tool bits and cutter heads.
The RCK-70 knife is specified for insert straight bits RC-1080, RC-1082, RC-1154, RC-2080, RC-2082 and RC-2154, so it provides the cutting edge in those bit bodies.
The RCK-70 insert knife is listed for trim bits RC-1000, RC-1008, RC-1010, RC-1012, RC-1014, RC-1024, RC-1026, RC-2257 and RC-2258, tying it directly to trimming applications.
The RCK-70 knife is specified for insert cutter heads 61288, 61292, 61340, 61360, 61362, 61460, 61462, 61470, 61472, 61480 and 61482, providing the working edge in those heads.
The 35 degree bevel defines the cutting angle for the RCK-70, setting how the edge meets the workpiece in its designated Amana straight bits, trim bits and cutter heads.
The "G" 35 degree general purpose knife is intended for wood, chipboard and plywood, matching common woodworking and panel processing tasks in those materials.
The Amana Tool 14mm x 14mm x 2mm 4-Cutting Edge General Purpose Insert Knife RCK-70 is sized and beveled for the listed Amana insert straight bits, trim bits and cutter heads, so it restores their intended cutting performance in wood, chipboard and plywood work.
