Description

The U300 ‘Big Shot’ Underground Piercing Tool is a premium pneumatic tool engineered for underground installations in water, gas, and cable/fibre optic projects.

Constructed with the highest quality standards, it is CNC machined to exact dimensional tolerances from a solid billet of nickel chromoly steel and fully heat treated for superior strength and wear resistance.

Designed to withstand high impact conditions, its pistons are treated with an anti-corrosive phosphate coating and feature an easily replaceable cartridge-style shock absorber along with a flexible air tube assembly to minimize internal deflection.

Backed by an warranty and excellent customer support, the U300 ‘Big Shot’ is the ideal choice for efficient and cost-effective moling.
