Concrete Core Drilling and Sawing

Gilson offers core drills for sample extraction from concrete and asphalt materials, along with a wide selection of diamond coring bits.


Electric Core Drills are used in concrete and asphalt core drilling. This drill is powered by a super-duty two-speed electric motor, and offers versatility, precise placement and an economical price.

Gasoline-Powered Core Drill offers fast drilling, a stable platform and precision-feed system, and requires no external power source. It is ideal for vertical coring of asphalt and concrete pavements and slabs, and other such structures.

Concrete Diamond Coring Bits are optimal for reinforced concrete and other hard materials, and perform well in wet use. Concrete and Diamond Coring Bits are available in open-head or closed-head models, ranging in size from 2in to 6.25in (50.8mm-158.8mm).

Expander Sets for Open-Head Concrete Coring Bits are required when using the Core Drilling Machine with Open-Head Coring Bits. Expander sets are reusable and range in size from 2in to 6.25in (50.8mm-158.8mm).

Core Retrieval products offer safe and easy extraction of standard 4in and 6in diameter cores, and include tongs and extractors. Tongs are long-handled, while extractors are more compact, and have a locked-in grip.

Masonry Saws are available in portable or heavy-duty models and used for trimming concrete, asphalt and masonry specimens in preparation for further testing. Submersible pumps allow use of water for wet cutting and reduction of nuisance dust.
