Net-roof Core Drill Bit Segments for Reinforced Concrete

Description

With an additional net layer on each side of the segments, net-roof type core drill bit segments are a premium version of the roof type. They retain the advantages of the roof type for quick and accurate positioning when starting drilling. Generally, the thickness of core bit segments is 1-2mm thicker than the blank barrels to protect the diamond core drill bits. Therefore, the extra net layer provides additional protection for the core bits.

If you’re considering retipping the diamond segments on your core drill bit, it’s a wise decision to reuse your empty barrels and reduce operating expenses. Xpert Diamond Tools provides the main 8 types of core bit segments for (reinforced)concrete drilling. If you’re unsure about which core drill bit segments to select, feel free to reach out to us, and we’ll suggest the most suitable options for your needs.

3 quality levels

To meet various concrete drilling applications, we provide three different quality levels of concrete core drill bit segments for drilling different types of concrete:

• Grade A for Heavily Reinforced Concrete
• Grade B for Mdium Reinforced Concrete
• Grade C for Concrete & Lightly Reinforced Concrete

Different grades of core bit segments have varying qualities of diamonds and segment formulas. Grade A segments use imported diamonds from Element Six in Ireland to ensure fast cutting through highly reinforced concrete. Other grades use top-brand domestic diamonds in China. Arix core drill bit segments are the fastest and can be used for dry cutting, while other segments are designed for wet drilling only.

Size of core drill bit segments

As a professional diamond segment manufacturer, Xpert Diamond Tools provides two different types of core drill bit segments for concrete and reinforced concrete drilling: crown type and bar type. The crown segment is ring-shaped and used only on small core drill bits under 50mm. Meanwhile, a series of bar segments have been developed, including Normal, Turbo, Roof, Turbo+Roof, Turbo+Zigzag, Arix, Net+Roof, and Aero. These have a much wider application and can be used on very large core drill bits, up to 500mm in diameter.
