Carbide Lollipop Ball Nose End Mill Overview
This solid carbide lollipop ball nose end mill combines a spherical cutting head with a relieved-neck design for undercutting, backside profiling and recessed-feature machining. Once the cutting head passes through a suitable opening, the reduced neck provides additional clearance for machining behind shoulders, around obstacles and inside difficult-to-reach areas. The tool can be used for backside deburring, cross-hole edge finishing, recessed grooves, mold-cavity finishing and complex 3D contouring.

2T / 3T by Size
Micro-Grain Carbide
Lollipop Cutting Geometry
Spherical Cutting Head
The rounded cutting form can contact recessed and curved surfaces from multiple directions, supporting radius features and complex side profiles.
Reduced-Neck Clearance
The relieved neck creates clearance between the cutting head and shank, allowing the tool to reach behind shoulders and into undercut regions.
R1–R10 Size Family
Multiple radius, neck and shank combinations cover small recessed features through larger backside and undercut applications.
Application-Specific Advantages
Undercut Access
Reach recessed side surfaces after the spherical head passes through a suitable access opening.
Backside Features
Suitable for backside edge finishing and deburring where direct front-side access is limited.
3D Contouring
The spherical head can follow curved and multi-angle surfaces in recessed mold and precision-component features.
Flexible Configuration
Radius, neck dimensions, overall length, coating and other specifications can be reviewed for custom applications.

Product Details
Lollipop Ball Nose End Mill Dimensions
The R1–R10 series combines different ball radii, relieved-neck dimensions, shank diameters and overall lengths for recessed and undercut machining. Tool selection should consider both the finished profile and the clearance required for the cutting head, neck, shank and holder throughout the complete toolpath.

Selection & Machining Guidance
- Radius Selection: Select the ball radius according to the required finished curved profile and available feature size.
- Entry Clearance: Confirm that the spherical cutting head can pass through the entry opening before lateral engagement begins.
- Relief Geometry: Use sufficient relief diameter and length to reach the undercut while retaining as much neck rigidity as practical.
- Controlled Engagement: Use smooth lead-in moves and progressive side passes rather than forcing the complete spherical profile into heavy engagement.
- Holder Clearance: Check the cutting head, relieved neck, shank and holder against surrounding workpiece geometry throughout the complete toolpath.
- Custom Tools: Provide a drawing or CAD model when the required radius, neck geometry, reach or overall length differs from the standard series.
Carbide Lollipop End Mill Customization
Ball radius, spherical-head geometry, relief diameter, relief length, shank diameter, overall length, cutting-edge configuration and coating can be customized for undercutting, backside profiling and recessed 3D machining. Standard R1–R10 configurations cover different feature sizes and access depths, while non-standard tools can be reviewed according to the finished profile, entry opening, undercut reach, workpiece material and available machine clearance.
| PARAMETER | MANUFACTURING CAPABILITIES |
|---|---|
| Ball Radius (R) | Standard R1–R10 radius configurations are available. Non-standard radii can be reviewed according to the required curved profile, undercut geometry and component drawing. |
| Spherical Head Geometry | Rounded cutting-head geometry can be configured for recessed grooves, backside edges, cross-hole features, undercuts and complex 3D surfaces. |
| Cutting Teeth | The current standard size matrix uses 2 cutting teeth for R1–R6 and 3 cutting teeth for R7–R10. Alternative configurations can be reviewed according to tool size and machining requirements. |
| Relief Diameter | Relief diameter can be matched to the ball radius, entry opening, undercut clearance and required neck rigidity. |
| Relief Length & Reach | Standard relief lengths range from 4–25 mm depending on tool size. Custom reach can be reviewed according to cavity depth, backside access and surrounding-wall clearance. |
| Shank Configuration | Straight cylindrical shanks from D4–D20 are used in the current standard series. Custom shank diameters and clamping lengths can be reviewed according to holder requirements. |
| Overall Length | Standard 50 mm, 60 mm and 75 mm overall lengths are available in the current series. Extended or drawing-defined lengths can be reviewed for deeper or restricted-access features. |
| Entry & Head Clearance | The entry opening must provide sufficient clearance for the spherical head before side engagement. Head diameter, neck geometry and access path should be checked against the component geometry. |
| Cutting-Edge Preparation | Cutting-edge preparation can be reviewed according to workpiece material, hardness, radius size, cutting engagement and required surface condition. |
| Coating Selection | Optional coating and surface treatment can be selected according to the workpiece material, hardness, machining temperature and coolant conditions. |
| Machining Application | Geometry can be reviewed for undercutting, backside profiling, cross-hole edge finishing, recessed grooves, mold-cavity finishing and complex 3D contouring. |
| Dimensional Tolerance | Drawing-defined tolerances can be reviewed for ball radius, head profile, relief diameter, relief length, shank diameter, overall length and finished cutting geometry. |
| Replacement Tool Matching | Existing lollipop or undercut cutters can be reproduced or modified based on a component drawing, existing tool drawing or physical sample. |
| OEM & Private Label | Laser marking, custom tool codes, labels and private-label packaging can be reviewed for distributors, tooling brands and OEM customers. |
