Diamond core drill set Smart SM-25-SET10G, 10 pieces, diameters 4–68 mm

Diamond core drill set Smart SM-25-SET10G comprises 10 diamond core bits with diameters ranging from 4 mm to 68 mm, designed for drilling precise holes in hard materials such as concrete, masonry and tile. The set covers a wide size range so users can select the most appropriate diameter for plumbing, electrical, fastening and finishing tasks without purchasing individual bits separately. The solid construction and diamond cutting edges provide consistent performance when used with compatible drill motors and holders.

Advantages

The Smart SM-25-SET10G offers a complete selection of core diameters in one package, reducing setup time and the need to switch between multiple suppliers. Diamond-segment cutting edges maintain cutting speed and edge life on abrasive substrates while providing clean hole edges in tile and masonry. The variety of diameters enables flexibility across different job requirements, and the set is suitable for both professional contractors and home users performing renovation or installation work.

How to use

Select the core bit with the required diameter for the task and attach it to a compatible drill motor or core drilling adaptor according to the machine manufacturer’s instructions. When drilling tile or masonry, begin at low speed to position the bit, then increase speed as appropriate for the material. Use steady pressure without forcing the bit; allow the diamond segments to cut naturally. For concrete and prolonged use, follow recommendations for cooling and chip removal as specified by the drilling equipment to maintain bit life and hole quality.

Recommendations

Use appropriate personal protective equipment (safety glasses, gloves, dust mask) and ensure the drill and core bits are compatible. For extended life and cleaner holes in hard materials, consider using water cooling or intermittent drilling to reduce heat and clear debris. Match drill speed and feed pressure to the selected diameter and material type.
