01
Special Boring Bar
Tecksun CNC Special Tools is an engineering-first manufacturer specializing in custom Special Boring Bars (Internal Turning Tools). We design custom internal tooling to overcome challenges standard catalog bars cannot solve—such as deep-hole ratios, internal clearance bottlenecks, and complex interior contours. Our custom boring bars allow manufacturers to achieve precise internal diameters, smooth bore finishes, and exact geometric tolerances.
- Deep-hole machining capability
- Superior internal bore accuracy
- Smooth surface finishes
- Custom-engineered geometries
02
FACE GROOVING BORING BAR
Tecksun CNC Special Tools is a specialized manufacturer of high-rigidity Face Grooving Boring Bars. Face grooving requires cutting a circular groove on the flat face of a component, creating unique machining challenges. We custom-engineer these bars with precise curved radial clearances matching your exact entry diameters, preventing friction rub and ensuring clean, deep axial grooving.
- High rigidity construction
- Precision radial clearance design
- Clean groove formation
- Reduced friction and vibration

SPECIAL FACE GROOVING BORING BAR
Tecksun CNC Special Tools is a premier manufacturer of high-precision Special Face Grooving Boring Bars. Standard catalog face grooving tools are limited by fixed diameter ranges and straightforward plunge geometries. We specialize in engineering custom face grooving bars capable of machining non-standard diameters, ultra-deep radial faces, compound internal curves, and interlocking facial grooves in a single operation.
- Non-standard diameter machining
- Deep radial groove capability
- Complex contour machining
- Single-pass groove solutions
04
FACE GROOVING CARTRIDGES
Tecksun CNC Special Tools is a premier manufacturer of high-precision Face Grooving Cartridges. Cartridge systems provide a flexible and modular alternative to solid tool bodies by acting as replaceable insert seats mounted onto larger master bars and specialized face milling heads. We custom-engineer these cartridges to provide manufacturers with an affordable and highly adaptable solution for cutting deep, precise circular grooves on component faces.
- Modular tooling system
- Easy insert replacement
- Cost-effective maintenance
- High precision grooving
