HRC45–HRC65 2-Flute Solid Carbide Ball Nose End Mill Overview
This 2-flute solid carbide ball nose end mill series is designed for 3D contouring, cavity machining, profiling and surface finishing in steel from general HRC45 applications through selected hardened-steel conditions up to HRC65. The full-radius cutting profile follows curved and free-form surfaces, while the two-flute geometry provides chip space and lower cutting resistance for mold cavities and complex profiles. Carbide grade, edge preparation and coating should be matched to the actual workpiece hardness.
Key Configuration
Full-Radius Ball Nose
Maintains progressive cutting contact on curved surfaces, cavities, fillets and complex 3D profiles.
Two-Flute Geometry
Balances cutting-edge support with chip space for semi-finishing and finishing operations.
Hardness-Matched Tool Series
Carbide grade, edge preparation and coating can be selected for HRC45, HRC55, HRC60 or HRC65 application levels.
Key Product Advantages
Smooth 3D Toolpaths
The ball profile supports continuous contact when following curved and free-form surfaces.
Stable Chip Evacuation
Two flutes provide chip space without giving up the edge support required for steel finishing.
Wide Hardness Coverage
Separate series configurations support general, pre-hardened and selected hardened steels up to HRC65.
Standard & Long Reach
Multiple shank and overall-length combinations cover regular profiles and deeper cavity access.
Milling Operations
Mold Cavity Milling
Profile Milling
Semi-Finishing
Surface Finishing

|---|---|---|---|---|---|
| Steel & Alloy Steel — HRC45–HRC50 | 120-180 | 0.03–0.06 | 0.3–0.6 × D | 0.05–0.20 × D | Contouring / Semi-Finishing / Finishing |

Ball Nose End Mill Application Guidance
- 3D Finishing: Select step-over according to the ball radius, required cusp height and target surface finish.
- Tool Center: Cutting speed approaches zero at the center of the ball; use suitable tool inclination or toolpath strategy where possible.
- Extended Reach: Reduce radial engagement and feed when using long overall lengths or increased tool overhang.
- Toolholding: Use a clean, low-runout precision holder and keep unnecessary overhang to a minimum.
- Series Selection: Confirm the workpiece grade and actual hardness before choosing the HRC45, HRC55, HRC60 or HRC65 configuration.
HRC45–HRC65 2-Flute Ball Nose End Mill Customization
Ball radius, cutting diameter, flute length, neck reach, overall length, carbide grade, cutting-edge preparation and coating can be configured for steel contour-milling applications. The HRC45, HRC55, HRC60 and HRC65 product levels use different substrate, edge and coating combinations rather than one universal geometry. Standard sizes are available for regular orders, while non-standard dimensions can be reviewed according to the workpiece grade, actual hardness, cavity depth, tool engagement and required surface finish.
