Amana Tool In-Groove Solid Carbide Corner Round 1/8 Inch Radius Insert Engraving Knife RCK-414
Solid Carbide 1-Edge
Corner Round Insert Engraving Knife
Amana Tool RCK-414 is the exact 1/8-inch radius corner round replacement insert knife engineered for the In-Groove™ CNC Insert Engraving System. It features an 8mm cutting height, solid carbide construction, and an optimized 80 IPM plunge feed rate.
Main Product Description
Amana Tool RCK-414 is the exact replacement insert knife shown on its dedicated official product page. The specification block establishes a verified 1/8-inch radius (R3.2mm), an 8mm cutting height (B), a 0.072-inch tip width, and a recommended plunge feed rate of 80 inches per minute. Constructed entirely from industrial-grade solid carbide, this insert yields clean edge finishes and prolonged service spans.
Amana Tool designs this corner round profile explicitly for the In-Groove™ CNC Insert Engraving System. It allows operators to perform detailed profiling, decorative signmaking, lettering, and precise outer-edge softening without purchasing entirely separate dedicated-profile solid tools. The single-flute geometry ensures efficient material clearing across diverse workpiece selections.
The official documentation rates this profile for hardwoods, softwoods, MDF, laminates, and extensive plastic configurations like acrylic, HDPE, and solid surfaces. Please note that while some V-tip elements in the In-Groove system handle aluminum etching, Amana Tool specifies that corner round inserts like the RCK-414 are not engineered for non-ferrous metal cutting.
Best Fit Applications
Product Highlights
In-Groove™ System Fit
Seamless interchangeability with standard RC-1075, RC-1076, RC-1077, and RC-1078 tool bodies to maximize CNC versatility.[cite: 6]
Premium Solid Carbide
Complete solid carbide construction maintains sharp cutting edge geometry across abrasive composites and dense plastics.[cite: 6]
Clean 1/8" Corner Profiles
Engineered for low vibration and controlled 80 IPM plunge rates to form crisp 3.2mm radiused profiles without burning.[cite: 6]
Compatibility & Installation Notes
Verify that the tool body is completely clear of debris before inserting the RCK-414 knife. This is a single replacement insert knife; tool bodies (such as RC-1075 or RC-1076) must be purchased separately. Ensure all retention screws are torqued down evenly per Amana Tool specification. While the In-Groove system handles diverse media, the RCK-414 corner round profile is explicitly restricted from non-ferrous metals. Follow standard CNC personal safety requirements and machine parameters.[cite: 6]
