Core Drilling Machine

Core Drilling Machine

HR 72.10

Compact and mobile, ‘Core-drill’ machine drills through hard rock, concrete, bitumen, tiles, marbles etc. and takes out cores for the preparation of laboratory samples.

Drive is through a powerful multi speed motor.

It can easily cut cores upto 150 mm dia.

The total assembly move on a pillar to adjust the tip height of the bit.

Pillar is fixed on to a base with two wheels for site shifting.

Geared motor moves on a slide and the slide can be rotated through 360o. Travel of the geared motor is approximately 600 mm and the cores of 400-450 mm can be easily taken out in single operation

Power of the Motor : 2500 Watts

Multiple Speeds (3 speeds) : 500,1200,2000 rpm

Power Supply : 230 Volts, 50 Hz AC.

Continuous Running time without damage to bits & barrels : 30 minutes

Core Drilling Machine

HR 72.12

It is a compact drilling machine that can drill through hard Rock, Concrete, Bitumen, tiles, and marbles. Adequate fixtures are provided to drill cores of 100 mm from 150 mm diameter Gyratory samples and multiple cores from slab of 410x 260x (max) 100mm height. The unit have a rigid, stable and vibration free platform. The unit have arrangement for both Lateral and longitudinal movement of the main sample holding jig to facilitate coring from bigger diameter cores and multi cores from slabs. The sample is moveable in X Y direction and the main frame is stationary and have Z movement. Due to the flexibility in multi direction multiple cores of different sizes can be cored from slab of the size given above.
