Custom Case | Solid Carbide Slitting Saw 47 × 1.0 × 16 mm, 72 Teeth for Fastener Slot Milling
Project Background
A manufacturer specializing in fasteners and precision stamped components required a custom solid carbide slitting saw for slot milling operations during the production of nuts, screws, and metal stamping parts.
The application demanded stable slot dimensions, clean edges, and reliable tool life in a high-volume production environment. Conventional cutters often produced excessive burrs and required frequent replacement, increasing production costs and machine downtime.
To improve machining consistency and production efficiency, a custom solid carbide slitting saw was manufactured according to the customer’s specifications.
Custom Tool Specification
| Item | Specification |
|---|---|
| Cutter Type | Solid Carbide Slitting Saw |
| Diameter (OD) | 47 mm (1.850″) |
| Thickness | 1.0 mm (0.039″) |
| Bore | 16 mm (0.630″) |
| Teeth | 72T |
| Material | Solid Tungsten Carbide |
| Coating | Uncoated |
| Application | Fastener Slot Milling and Stamped Components |
The customer selected an uncoated carbide cutter for this application.
For higher cutting speeds or abrasive materials, customized PVD coatings such as TiAlN, AlCrN, and DLC are also available to improve wear resistance and extend tool life.
Challenges in Fastener Slot Milling
Fastener manufacturing requires high dimensional consistency and repeatable machining quality, especially in mass production environments.
Common machining challenges include:
- Burr formation on slot edges
- Inconsistent slot width during long production runs
- Premature tool wear
- Frequent tool replacement and machine stoppages
- Surface finish issues on precision stamped parts
Maintaining stable tooling performance is critical for ensuring both product quality and production efficiency.
Customized Solution
The custom 47 mm carbide slitting saw was optimized specifically for fastener slot milling applications.
The 1.0 mm cutting width provides an ideal balance between rigidity and cutting precision, making it suitable for a wide range of nuts, screws, and stamped metal components.
The 72-tooth design distributes cutting forces evenly and improves cutting smoothness, helping reduce burr formation while maintaining excellent dimensional consistency.
Manufactured from premium solid tungsten carbide, the cutter offers outstanding wear resistance and production stability for continuous manufacturing environments.
Results Achieved
Following implementation, the customer achieved several improvements:
- Improved slot dimensional consistency
- Reduced burr formation
- Longer tool service life
- Lower tooling costs
- Increased production efficiency
The custom carbide slitting saw became a standard production tool for the customer’s fastener manufacturing operations.
