Core bit choice depends on the material and hole diameter: standard segmented bits handle concrete and reinforced concrete efficiently, while specialised bits with adapted bond hardness are needed for porcelain stoneware, brick, sandwich panels or tungsten carbide to avoid glazing or premature wear. Laser-welded segments, used on the premier range, resist heat better and last longer under continuous coring. Threading (1/2 GAS, M14, 1 1/4 UNC) must match the drill or extension in use; all thread types fit the Pic Epeiche drill directly or via the drilling adapter range.

Frequently asked questions

Which diamond core bit suits reinforced concrete coring?

Sept Tools' standard and premier core bit ranges cover reinforced concrete across diameters from O9 to O500. The premier range uses laser-welded segments for higher resistance when coring through rebar-heavy sections, extending service life on demanding sites.

Is there a diamond core bit for porcelain stoneware or brick?

Yes. Beyond concrete, the 109-reference range includes specialised core bits for porcelain stoneware, brick, sandwich panels, fibreglass, cladding sheet metal, multi-composite materials and tungsten carbide, each with a bond matched to the material and mounting thread.

Which drill do diamond core bits mount on?

All Sept Tools diamond core bit types mount on the Pic Epeiche brushless drill, including its on-stand variant. Threading options are 1/2 GAS, M14 and 1 1/4 UNC depending on the bit reference and the job's diameter and depth.

How do I order diamond core bits without listed prices?
