60? .010" V TIP / RC-1075/1076, RCK-381

In-Groove Insert Engraving Knife For CNC Work

In-Groove insert engraving knife from Amana Tool is a solid carbide knife designed for the In-Groove insert engraving system, so it serves as a precise cutting edge within that dedicated CNC tool body setup. The knife is specified as a .010 inch by 7.5mm, 60 degree V-tip, which means it presents a fine V-shaped cutting profile that is suited to detailed engraving where a narrow kerf and consistent angle matter. Amana Tool identifies this knife as manufacturer part RCK-381 and as a solid carbide insert 30 degree V tip engraving knife for the In-Groove system, which ties it directly to the branded In-Groove CNC insert engraving tool bodies used in industrial and shop CNC environments. The product sits in the Bits, Blades and Cutters replacement parts classification, so it is intended to refresh cutting performance in an existing In-Groove setup without changing the base tool body.

Key In-Groove Knife Details That Support Work

• The In-Groove insert engraving system uses one tool body with 30 unique insert knives, so this RCK-381 knife fits into a modular approach where different knives can be swapped to match specific engraving applications without replacing the main body.
• Industrial quality insert knives in this system are described as producing crisp clean cuts, which means the edge geometry and material are tuned to leave sharp engraving lines that reduce rework on detailed lettering or graphics.
• These insert knives are stated to last at least twice as long as comparable solid carbide bits, so the RCK-381 knife supports longer run times between changeouts in CNC operations that rely on consistent engraving across multiple parts or batches.
• The engraving system is engineered to quickly interchange inserts while mounted in CNC machines, so using this knife allows cutters to be changed without pulling the tool body, which streamlines job changeovers and keeps machine downtime lower.
• CNC tool bodies in the system are expertly balanced for virtually no vibration, so once the RCK-381 knife is seated in the body it works within a low-vibration assembly that helps maintain edge tracking and surface finish in engraving passes.
• The system is identified as an excellent solution for etching, so this knife supports that role by providing a V-tip insert suited to creating etched details where controlled depth and line definition are important.

Engraving Knife Fit Within The In-Groove System

This solid carbide insert 30 degree V tip engraving knife is described specifically for the In-Groove system, so its geometry and interface are matched to the corresponding In-Groove CNC insert engraving tool bodies. The knife is called out with a .010 inch by 7.5mm, 60 degree V-tip specification, which establishes the cutting profile that the In-Groove body presents to the workpiece and helps users select this insert when they need that particular V-angle and width for their engraving patterns. Because the overall system is engineered to allow inserts to be interchanged while mounted in CNC machines, this RCK-381 knife is intended to slot into that quick-change workflow, serving as a direct replacement insert that keeps the tool body clamped while only the cutting edge is switched.

Using This RCK-381 Knife In CNC Engraving

Where This In-Groove Knife Is Applied

The solid carbide insert 30 degree V tip engraving knife for the In-Groove system is positioned for use in CNC engraving tasks where the In-Groove CNC insert engraving tool body is already part of the setup, so it plays the role of the replaceable cutting tip in that assembly. The knife is tied directly to the In-Groove insert engraving system, which is presented as having one tool body paired with 30 unique insert knives, so this RCK-381 version serves as one of those selectable profiles for engraving and etching work. With its .010 inch by 7.5mm, 60 degree V-tip specification, it provides a defined V-cut that supports engraving operations needing a controlled, narrow groove, such as lettering, symbols, or other detailed line work that benefits from a consistent angle and edge quality across multiple passes.

Why This Knife Supports Repeatable Results

The industrial quality insert knives in the In-Groove system, including this RCK-381 solid carbide knife, are described as producing crisp clean cuts, which supports repeatable results by limiting fuzzing or deformation along engraved edges during production runs. Their stated lifespan of at least twice as long as comparable solid carbide bits means the cutting edge maintains its performance over more cycles, helping engravings on later parts match those from initial runs with less edge wear impact. Because the In-Groove system is engineered so inserts can be quickly interchanged while mounted in CNC machines, this knife contributes to consistent setups by allowing the same tool body and its balanced, low-vibration characteristics to remain in place while only the insert is changed. The expertly balanced CNC tool bodies are noted as providing virtually no vibration, so when this knife is locked into the body, the engraving passes benefit from stable tracking that supports accuracy and line sharpness. The system is also identified as an excellent solution for etching, and this V-tip knife fits that description by providing a profile capable of defining etched-style details where repeatable depth and clarity are central to the finished appearance.

Common Questions About The RCK-381 In-Groove Knife

Selecting This In-Groove Knife For Engraving Jobs

The In-Groove insert engraving knife RCK-381 combines a solid carbide 30 degree V tip design with a .010 inch by 7.5mm, 60 degree V-tip specification, so it offers a defined profile tailored to the In-Groove CNC insert engraving tool bodies. As one of the 30 unique insert knives supported by the system, it allows installers and CNC operators using In-Groove bodies to match this specific V-tip geometry to engraving or etching work that calls for crisp clean cuts and stable tracking. For buyers relying on the In-Groove system, choosing this Amana Tool RCK-381 knife provides a replacement insert that fits the modular, quick-change approach and supports consistent engraving performance across production jobs.
