Ball Nose, Back Draft, Flat Bottom and High-Feed Insert Grades & Selection Guide
| Uncoated (Base Grade) |
with Coating | Description | Specifications |
|---|---|---|---|
| F1 | Micro-grain tungsten carbide with high edge strength and good toughness. Good for machining steels, stainless steels, high-temperature alloys, cast iron and nonferrous materials. | (C-2), (K10) | |
| FPX | Titanium carbon nitride (TiCN) is a functional hard coating offering an optimal combination of hardness, toughness and antifriction characteristics. TiCN is recommended for high shock resistance. Excellent titanium grade. | 3000 HV, 750°F, .4 Co | |
| FPO | High-performance, medium-temperature grade. Optimum performance and wear resistance in most soft steels, soft stainless steels and cast irons. | 3200 HV, 1850°F, .4 Co | |
| FPA | Aluminum titanium nitride (AlTiN) is recommended when extra hardness and heat resistance are required. AlTiN makes both machining at higher speeds and dry machining possible. | 3600 HV, 2000°F, .4 Co | |
| FP-GLH | Premium high-temperature grade. Unbeatable performance and wear resistance in high-heat applications such as harder steels, tough stainless steels and high-temperature alloys. | 3600 HV, 2000°F, .2 Co | |
| PCD | Only available for BDR-0500-N and BDR-0750-N inserts. Premium diamond-tipped grade for carbon or light aluminum milling. Use in dedicated holder for the optimum in wear resistance, up to 100 times standard PVD-coated inserts. | Brazed-On Diamond Tips |
- "FP-GLH" and "FPA" coatings are best suited for higher operating speeds (temperatures) and harder materials.
- "FPO" and "FPX"coatings are best suited for low to medium operating speeds (temperatures) and softer materials.
- Other coatings available on request. Contact Dapra for details.
