4-cutting edge insert knife describes this Amana Tool solid carbide replacement knife designed for CNC use. The knife is specified at 30mm straight, so it suits straight cutting operations where a flat, accurate path is needed. Its solid carbide construction provides a hard cutting edge that stands up to demanding routing of engineered sheet goods. The knife size is identified as 29.5mm x 12mm x 1.5mm, giving a compact insert format for compatible cutter heads. With four cutting edges on each insert, the knife can be rotated through multiple positions, which extends usable life before change-out. This design helps maintain edge quality over time, supporting consistent finish on production runs. The manufacturer part number HRK-30 clearly ties the insert to matching Amana Tool cutter bodies, which supports precise part identification when reordering or standardizing tooling in a shop.
This solid carbide insert knife carries a 35 degree bevel, giving the cutting edge a defined shearing angle. That bevel helps the edge slice through MDF, chipboard, and solid surface rather than scraping, which supports a cleaner cut face. The bevel geometry also plays a role in chip formation, guiding waste away from the cut line for more stable cutting on CNC passes. Because the insert is described as straight, it supports predictable tracking along programmed toolpaths, helping reduce variation at edges and corners. The combination of bevel angle and straight form is set up for panel work where a crisp, repeatable edge is important across multiple sheets.
This HRK-30 solid carbide 4-cutting edge insert knife is described for materials such as MDF, chipboard, and solid surface, so it is oriented to common cabinet and fixture substrates. In MDF work, the hard carbide edge pairs with the 35 degree bevel to slice dense fiber rather than tearing it, supporting cleaner routed profiles and edges. In chipboard, the solid carbide edge handles abrasive particles while the straight insert format maintains a steady path along the sheet. With solid surface materials, the defined bevel helps manage chip removal along flat runs, supporting uniform cuts on countertops or panels. Because the insert is designed as a CNC replacement knife, it fits naturally into CNC routing workflows where consistent geometry and predictable wear patterns are important. Across these material groups, the specified size of 29.5mm x 12mm x 1.5mm keeps the insert compact for use on multi-insert heads.
The four cutting edges on this insert have direct impact on workflow, because each edge can be rotated into position as earlier edges wear, maintaining similar geometry without changing the insert body. That rotation approach supports consistent toolpath results over multiple production cycles, since the straight 30mm form and 35 degree bevel remain the same from edge to edge. The solid carbide body provides a uniform substrate across all four edges, so each new edge behaves like the original in cut feel and finish. The defined dimensions of 29.5mm x 12mm x 1.5mm help maintain balance and spacing on the cutter head, which supports smoother running at CNC speeds. The HRK-30 part number links these characteristics to a specific insert family, aiding in standardizing setups across machines so operators can expect similar performance whenever this insert is used.
The HRK-30 is a solid carbide 4-cutting edge insert knife, so it functions as a replaceable cutting insert on compatible cutter heads for CNC routing tasks.
This insert knife is described for MDF, chipboard, and solid surface, so it targets common panel and surfacing materials used in cabinetry and fixture production.
The HRK-30 provides four cutting edges on each insert, which allows rotating to fresh edges and extending service life before full insert replacement is needed.
This insert knife is identified as 29.5mm x 12mm x 1.5mm, giving it a compact rectangular profile suited to multi-insert cutter heads in CNC setups.
The 30mm straight description indicates a straight-edge insert geometry around 30mm, which supports linear routing passes and clean edges on flat panel work.
The 35 degree bevel sets the cutting angle, helping the solid carbide edge shear MDF, chipboard, and solid surface for cleaner cuts and smoother finishes.
This Amana Tool HRK-30 solid carbide 4-cutting edge insert knife is sized at 29.5mm x 12mm x 1.5mm with a 30mm straight description and a 35 degree bevel, aligning it with CNC panel work in MDF, chipboard, and solid surface. The four usable edges and defined bevel angle give a predictable cutting profile across multiple rotations, supporting steady performance as jobs repeat. For shops standardizing on solid carbide insert tooling, this specific HRK-30 designation ties geometry, material, and edge count together so tooling choices stay consistent from project to project.
