DSPIAE Spherical Bur (4mm) CT-40
The DSPIAE CT-40 is a robust 4mm spherical bur crafted for large-scale shaping, hollowing, and detailing in plastic and resin models. Ideal for modellers working on bigger components or structural pieces, this tool allows for clean and uniform shaping of rounded cavities and recesses with confidence and control.
- 4mm spherical tungsten steel head for wide-area shaping and smoothing
- Perfect for creating large recesses, domed details, or scooped surfaces
- Designed for compatibility with 3mm shank rotary tools and pin vises
- Durable, wear-resistant construction for long-lasting performance
- Excellent for plastic, resin, and other soft modelling materials
The CT-40’s larger cutting head offers efficient material removal while maintaining control, making it ideal for modifying vehicle components, figure bases, or hollowing interior sections on large kits. It delivers a clean, professional finish even in demanding applications.
High-Quality Materials
Manufactured from forged tungsten steel, the CT-40 resists chipping and blunting, ensuring a sharp edge and smooth finish across repeated use. Its spherical profile allows for flowing curves without gouging or chatter.
Recommended Applications
- Large-scale cavity shaping
- Refining domed areas and rounded detailing
- Working on figure bases, engines, or vehicle interiors
Part of DSPIAE’s professional line of burs, the CT-40 brings power, precision, and efficiency to your toolkit—especially for projects where precision meets scale.
