RCK-70 replacement knife for Amana insert tools

General Purpose Insert Knife For Routing Tasks

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.

Key Details That Matter On The Job

• The 4 cutting edges provide multiple rotations, extending insert life and supporting steady cut quality across several setups before a new knife is needed.
• The 35 degree bevel on all knives sets the cutting geometry, which shapes how the edge enters the material and supports a controlled general purpose cut.
• The general purpose "G" 35 degree design targets wood, chipboard and plywood, so one insert style can serve mixed panel and solid stock work in the same shop.
• The availability of new grades for softwood, hardwood, MDF, solid surface and micro-finish applications means the insert line addresses different material groups and surface requirements.

Insert Knife Size And Bevel For Accurate Fit

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.

Using This RCK-70 Knife In Woodworking Setups

Where This General Purpose Insert Knife Fits

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.

Why The Bevel, Edges And Grades Support Results

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.
