Core Drilling Machine (Motorised)
Core Drilling Machine (Motorised) (Product Code: SLE/CE/104) is an electric core drill used to cut cylindrical cores from hardened concrete, masonry and rock for strength testing and structural inspection in civil engineering laboratories and on construction sites. Testing labs, consultants and engineering colleges use it with core bits from 25 mm to 150 mm in diameter, driven by a 2800 W motor running at 840 rpm without load. It is supplied by Jain Scientific Equipments Pvt Ltd (ScienceLab), Ambala, India.

What Is the Motorised Core Drill Used For?
Cores drilled from an existing slab, beam, column or pavement are the most direct way to check the strength and quality of concrete in a finished structure. The drill cuts an annular groove with a hollow core bit, and the cylinder left inside is broken off and taken to the laboratory for compression testing, density or depth checks. Water fed through the swivel cools the bit and flushes out cutting slurry while the drill runs.
Choose the bit diameter to suit the aggregate size and the test you plan, from 25 mm for small checks to 150 mm for larger cores. Keep the water supply steady, feed the bit gently rather than forcing it, and let the friction clutch slip if the bit binds. Replace the swivel seal once it starts to leak. As a laboratory instruments supplier in India, we quote this drill to colleges and testing labs alongside the equipment used to test the cores.
What to Specify When Ordering
- Number of drilling machines required
- Core bit diameters you need within the 25–150 mm capacity (ask us about bits)
- Confirmation that your site or lab supply is ~220 V / 50 Hz
- Any spare water swivel seals (ask us)

Frequently Asked Questions
What core bit sizes can the Core Drilling Machine (Motorised) take?
The Core Drilling Machine (Motorised) has a bit capacity of 25 mm to 150 mm diameter, and its maximum bit diameter is listed as Ø50 mm / 100 mm / 150 mm. The spindle has a 1 1/4″ UNC male thread for fitting the core bit.
What power does the Core Drilling Machine (Motorised) need?
The Core Drilling Machine (Motorised) is rated for ~220 V / 50 Hz with a power input of 2800 W, and its no-load speed is 840 rpm. Check that your site generator or laboratory supply can deliver this load before drilling.
How is the motor of the Core Drilling Machine (Motorised) protected?
The Core Drilling Machine (Motorised) is equipped with a friction clutch and overload current protection to protect the motor. If the bit jams in hard aggregate or steel, the clutch slips instead of passing the full shock to the gearbox and motor.
Are core bits included with the Core Drilling Machine (Motorised)?
