Concrete Diamond Core Drill Bits

Gilson's Concrete Diamond Coring Bits can be used to drill through concrete, reinforced concrete, cured concrete, stone, asphalt, and other hard materials. Open-head and closed-head coring bits are available and can be used with gasoline or electric-powered powered core drills. Bits are constructed for wet use and are fast-cutting when used according to design applications.

Closed-head bits have an overall length of 20.5in (520.7mm) and are capable of coring up to a total depth of 18in (457.2mm). Open-head bits have an overall length of 14.75in (374.65mm) and are capable of coring to a total depth of 12.5in (317.5mm). The final core diameter is approximately 0.25in (6.35mm) smaller than the outside diameter. All concrete core bits may be refurbished when worn. Diamond coring bits are designed with custom trapezoid segments specifically designed to offer durable performance and longevity under optimal coring conditions.

Open-Head Coring Bits require expander sets listed for attachment to drills. These bits are slightly less expensive and the expander sets can be reused many times as the core barrels wear out and are replaced. They are an economical choice for high-output and heavy-use applications.

Closed-Head Coring Bits are one-piece construction for convenience and easy, direct attachment to drills. There are no extra parts to buy or lose. These are best suited for light-to-medium-duty or for occasional use. Bits have a 1.25inx7tpi and fit standard core drills.
