GY6 Engine Case Boring Tool Replacement Blades

Spare Cutting Blades for the GY6 Engine Case Boring Tool

These spare blades are made to fit the GY6 Engine Case Boring Tool and help keep it cutting well. They are used when enlarging GY6 engine cases so that a bigger bore cylinder can be installed. They belong to our GY6 scooter parts range and are built for precise boring between 54mm and 61mm, which covers common engine upgrade sizes.

Carbide Tip Brazed to Steel

Every blade has a steel shank with a carbide cutting tip brazed on. The construction supports sharper, more accurate cuts and longer wear when you bore engine cases.

Bore Size Range

The blades handle bores from 54mm to 61mm, the sizes usually needed for GY6 big bore upgrades. They suit both 125cc and 150cc GY6 engine cases, so they work across several modification projects.
