Rhino-Feed Inserts: Mini-Feed, Mid-Feed and Heavy-Feed
High-Feed Inserts
- Strong design allows high feed rates in all materials
- Positive clearance provides excellent ramping and helixing capabilities
- Multiple geometries for either smooth cutting or strong edge conditions
- Simple but effective grade variety provides strong performance in all materials
Cutting Edge Comparison
| Cutting Edge | Edge Strength | Tool Pressure | Heat Creation |
|---|---|---|---|
| T (T-Land) | Strongest | Highest | Highest |
| D (Dished) | Medium | Lowest | Lowest |
 | "T" inserts have a reinforced cutting edge for steels, irons and hard milling |
 | "D" inserts have a positive cutting geometry, designed to reduce cutting forces and heat. This edge is suitable for all materials. |

Mini-Feed Inserts Insert IC Thickness # of Usable Edges Corner Radius (Actual) Corner Radius (Program) DOC (Max.) DOC (Recommended) FPT
(Compensated)RF08-D 8MM .125" 3 .062" .088" .030" .010-.025" .012-.032" - * A special corner radius value is required for correct programming of a high-feed insert. Using the program radius avoids gouging of the corners in the workpiece material.
- The high-feed insert will naturally leave a small amount of extra material at the bottom-most layer of the cut, at the intersection of the wall and pocket floor.
- RHINO-FEED inserts are labeled with dots to indicate die position during pressing. For the most accurate runout when loaded into the cutter body, make sure each insert is loaded with the corresponding edge.

| Shock & Wear Resistance | Uncoated (Base Grade) | with Coating | Description | Specifications |
|---|---|---|---|---|
| TOUGHEST Shock Resistance |
DMK30 | Moderate wear resistance/high shock resistance. Recommended for interrupted or unstable steel, most 300 series stainless steel, high-temperature alloys and cast iron applications. | ANSI C1-C2, ISO K25-K40, M25-M35 | |
| DMK30-HP | High-performance medium-temperature grade. Optimum performance and wear resistance in most soft steels, soft stainless steels and cast irons. | |||
| DMK30-GLH | Premium high-temperature coating. Best resistance to heat for high-shock applications. Excellent for tough stainless steels, high-temperature alloys and soft tool steels. | |||
| MEDIUM Shock and Wear |
DMK25 | Micro-grain carbide providing higher wear resistance and good shock resistance for applications in tough stainless steels, high-temperature alloys, irons and many tool steels. | ANSI C2-C3, ISO K15-K30, M15-M30 | |
| DMK25-HP | High-performance medium-temperature grade. Optimum performance and wear resistance in most soft steels, soft stainless steels and cast irons. | |||
| DMK25-GLH | Premium high-temperature coating. Outstanding performance and wear resistance in high-heat applications involving tough stainless steels, high-temperature alloys and many tool steels. | |||
| MEDIUM Shock and Wear |
DMP25 | High wear resistance/moderate shock resistance. Recommended for most steel and ductile iron applications. | ANSI C5-C6, ISO P25-P40 | |
| DMP25-HP | High-performance medium-temperature grade. Optimum performance and wear resistance in most soft steels and cast irons. | |||
| DMP25-GLH | Premium high-temperature grade. Unbeatable performance and wear resistance in high-heat applications such as higher speed machining in steels (< 44 Rc) and ductile irons. |
- DMK30-HP is a good first choice for most applications.
