Ball Nose Insert Grade Selection
Ball Nose, Back Draft, Flat Bottom and High-Feed Insert Grades
Uncoated (Base Grade) | with Coating | Description | Specifications |
---|---|---|---|
F1 | Sub-micron 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) | |
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 |
|
FP-GLH | Premium high-temperature grade. Strong 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 |
|
FP-TS NEW |
New coating intended for general-purpose use across a wide variety of materials including steels and stainless steels. High-temperature grade providing excellent heat and wear resistance. Use for most applications. | 3800 HV, 2200°F, .2 Co |
|
FP-HM NEW |
New coating intended primarily for high-temperature applications like hardened steels, tough stainless steels, high-temperature alloys, and titanium. Highest hardness and heat resistance. Also excellent for irons. | 4000 HV, 2400°F, .2 Co |
|
FPD | CVD-applied PCD (diamond) coating. Excellent wear resistance in nonmetallic materials such as graphite, epoxy-based resins and plastics. | CVD Diamond Coating |
|
PCD | Premium diamond-tipped grade for carbon, composites, 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-DL NEW |
Diamond-like coating for achieving better tool life vs. standard PVD coatings in graphite and composite applications, without the high cost of diamond-tipped or diamond-coated inserts. | 5000 HV, 1000°F, .2 Co |
- “FP-GLH” and “FP-HM” coatings are best suited for higher operating speeds (temperatures) and harder materials.
- “FPO” and “FP-TS” coatings are best suited for low to medium operating speeds (temperatures) and softer materials.
