No sacrificial drill tip. Clear passage for concrete and reinforcement.<\/h2>\n\n\n

The Olivier reusable drill tip closes the drill pipe during drilling. When rotation is reversed for extraction, the integrated gates open automatically. They remain attached to the auger head and return to the surface with it. A sacrificial steel drill tip is therefore no longer needed.<\/p>\n\n\n

Key benefits<\/h2>\n\n
<\/path><\/svg>

No sacrificial steel left behind<\/h3><\/div>

No sacrificial steel drill tip remains in the ground. The integrated gates are reused.<\/p><\/div>

<\/path><\/path><\/svg>

Safer working<\/h3><\/div>

There is no need for anyone to fit a sacrificial drill tip beneath the auger head. Eliminating this operation reduces exposure to the risks associated with fitting the tip.<\/p><\/div>

<\/path><\/path><\/svg>

Lower CO\u2082 emissions through reuse<\/h3><\/div>

There is no need to manufacture, transport and handle a new sacrificial steel drill tip for every pile. This avoids material consumption and the associated CO\u2082 emissions, pile after pile.<\/p><\/div>

<\/path><\/svg>

Clear passage for concrete and reinforcement<\/h3><\/div>

The open gates provide clear passage for concrete and reinforcement. During reverse extraction, concrete flows out of the drill pipe while the pre-positioned reinforcement cage remains at the intended depth.<\/p><\/div><\/div>\n\n

How the reusable drill tip works<\/h2>\n\n
01<\/span>

Drill with the gates closed<\/h3>

The closed gates form the drill tip and seal the drill pipe during drilling, preventing soil and water from entering.<\/p><\/div>

02<\/span>

Place the reinforcement<\/h3>

At the required depth, the reinforcement cage is lowered through the drill pipe. Concrete supply then begins.<\/p><\/div>

03<\/span>

Open the gates and extract<\/h3>

The gates open automatically during reverse extraction. The reinforcement remains at depth while concrete is supplied. The gates return to the surface with the auger head.<\/p><\/div><\/div>\n\n
