JPT Bottle Boring Tools
“Bottle Boring Tools” – Built to Cut What Others Can’t
Not all bores are straight. Some curve, swell, or reverse direction—like a bottle. These internal bores aren’t just tricky—they’re impossible with off-the-shelf tooling. When profiles balloon, taper, or reverse mid-bore, you’re not boring anymore—you’re bottle boring. At JPT, we build the tools that make those parts possible using our innovative bottle boring tools.
What is Bottle Boring?
Bottle boring tools are a type of internal boring tool designed to machine complex internal profiles, especially those with undercuts, curved or “bottle-shaped” cavities. They’re often used in high-precision applications where traditional boring tools can’t reach or conform to the shape needed.
These features are often found in:
- Automotive: Machining of connecting rods, transmission parts, or other cast/forged parts with internal pockets that have variable diameters or bulging geometries.
- Truck and Heavy Equipment: Internal passageways, undercuts, grooves and multiple bore diameters.
- Aerospace: Structural components with weight-reducing internal cavities.
- Medical: Complex orthopedic implant bores.
- Die/Mold: Internal contouring of forms or cavities.
- Bottle Industry: Bottle boring tools are essential here for shaping intricate bottle-like cavities.
