Carbide Lollipop Ball Nose End Mill Overview
This solid carbide lollipop ball nose end mill is designed for radiused T-slot milling, undercutting, backside-edge machining and recessed 3D profiling where conventional straight end mills cannot reach. The near-spherical cutting head works together with a relieved neck to provide side and backside access after the tool enters through a suitable opening. Standard sizes cover R1–R10, with 2-tooth configurations used for R1–R6 and 3-tooth configurations for R7–R10.

Lollipop Ball Nose Geometry
Spherical Cutting Head
The rounded cutting head can contact surfaces above, below and around its centerline, allowing radiused grooves and complex recessed profiles to be machined.
Relieved Neck
The reduced neck provides clearance behind the entry opening so the cutting head can reach undercuts, backside edges and recessed side surfaces.
R1–R10 Radius Series
A broad radius range supports small recessed features through larger radiused T-slot and side-profile applications.
Application-Specific Advantages
Undercut Access
Reach behind cavity walls, shoulders and openings after a suitable access path has been prepared.
Radiused Profiles
The spherical head produces blended and rounded forms rather than the flat form of a conventional T-slot cutter.
Multi-Angle Contact
Suitable for curved side surfaces and recessed 3D forms requiring contact from different tool orientations.
Solid Carbide Body
Solid carbide construction provides the rigid tool body required for controlled CNC profile milling.

Typical Application Areas
| APPLICATION | MACHINING FEATURE |
|---|---|
| Radiused T-Slots | Rounded internal recesses and side grooves |
| Undercut Features | Recessed surfaces behind shoulders, cavity walls and openings |
| Backside Edges | Edge blending and deburring when machine access permits |
| Complex 3D Components | Curved and multi-angle recessed side surfaces |
Profile Note:
A lollipop ball nose cutter produces a rounded cutting form. If the component requires a flat, parallel-sided T-slot or a defined angled dovetail profile, select the corresponding T-slot or dovetail form cutter instead.
Recommended Undercut Milling Workflow
Prepare the Access Slot
Machine an entry slot or opening large enough for the spherical cutting head to pass through safely.
Enter Without Side Contact
Move the ball head through the prepared opening without forcing the full spherical profile into solid material.
Use Controlled Side Passes
Apply smooth lead-in moves and controlled radial engagement to reduce load on the relieved neck.
Product Details
Lollipop Ball Nose End Mill Dimensions
Tool selection should be based on ball radius, spherical-head envelope, relief diameter, relief length, shank diameter and overall length. The relieved neck must provide sufficient clearance throughout the complete undercut or backside-machining toolpath.

Stable Machining Guidance
- Use the Largest Practical Neck: Select enough relief for the required undercut without choosing an unnecessarily slender neck.
- Limit Radial Engagement: Use progressive side passes rather than unnecessary full-profile engagement because the relieved neck is less rigid than the main shank.
- Check Entry Clearance: The prepared slot or opening must safely clear the spherical cutting head before side engagement begins.
- Control Chip Evacuation: Direct air or appropriate coolant toward the recessed cutting zone to reduce chip recutting and packing.
- Simulate the Complete Tool: Check the ball head, relieved neck, shank, holder and withdrawal path in CAM before machining enclosed or difficult-access features.
Carbide Lollipop Ball Nose End Mill Customization
Ball radius, relief diameter, relief length, shank diameter, overall length, cutting-tooth configuration, cutting-edge preparation and surface treatment can be configured for radiused T-slot, undercut and backside-profile machining. Standard configurations cover R1–R10, with 2-tooth designs used for R1–R6 and 3-tooth designs for R7–R10. Non-standard dimensions can be reviewed according to the entry opening, required undercut reach, finished profile, workpiece material and available holder clearance.
| PARAMETER | MANUFACTURING CAPABILITIES |
|---|---|
| Ball Radius (R) | The documented standard series covers R1, R1.5, R2, R2.5, R3, R4, R5, R6, R7, R8, R9 and R10. Non-standard radii can be reviewed according to the required finished profile and component drawing. |
| Spherical Head Geometry | Near-spherical cutting-head geometry can be matched to radiused grooves, recessed side surfaces, backside features and complex undercut profiles. |
| Relief Diameter | The standard series uses relief diameters from D1 to D10 depending on ball radius. Non-standard neck diameters can be reviewed according to entry clearance, undercut depth and required tool rigidity. |
| Relief Length | Standard relief lengths range from 4 mm to 25 mm according to tool size. Longer or application-specific reach can be reviewed according to cavity depth and surrounding clearance. |

| Shank Configuration | Straight cylindrical shank with standard sizes from D4 to D20 in the documented series. Drawing-defined shank diameters can be reviewed according to holder and machine requirements. |
| Longitud total | The current standard series uses 50 mm, 60 mm and 75 mm overall lengths. Custom lengths can be reviewed according to undercut depth, holder clearance and tool-rigidity requirements. |
| Head & Entry Clearance | The entry slot or opening must provide sufficient clearance for the spherical head to pass through before side engagement. Head envelope and access geometry should be checked against the component drawing. |
| Undercut Reach | Relief diameter and relief length can be matched to the required backside reach, cavity depth and side-wall clearance while maintaining as much neck rigidity as practical. |
| Cutting-Edge Preparation | Cutting-edge preparation can be reviewed according to workpiece material, hardness, cutting engagement, radius size and required surface condition. |
| Coating & Surface Treatment | Coating and surface treatment can be selected according to the workpiece grade, hardness, cutting conditions and required wear resistance. |
