This is a diamond core drill with the excelled drilling capacity developed by the total balance design. Piping installation work of the electric, a waterway, gas, a telephone, an air conditioning, etc. The test-piece extraction work for the strength test of all reinforced concrete, such as water and sewage, a dam, tunnel, and a bridge, etc. can be done smoothly.

Double isolation structure of grounding needless

The motor of the double isolation structure of safe grounding needless is used by all model safety.

A circuit breaker is equipped standardly

The burning prevention by overload current is equipped standardly with the circuit breaker.

The safe design which intercepts a rotation at the time of a drill-bit hold

Torque limiter clutch which intercepts a rotation of a drill bit is adopted as the unusual impact in drilling.

Roller clamp system and angle cut mechanism are adopted as a hoisting pole

By roller clamp system, the slide of a pole is smooth. And it is less wobble. High-precision stable drilling can be angle adjustment at 60°- 90° is possible.

High durability is held by no lubrication

Grease pack system is adopted as a gear mechanism, and it is high durability with gear in no lubrication.
