## Long description

Diamond drill bit Smart SM-25-1020 102 mm with M14 shank is designed for drilling porcelain and other hard ceramics. The segmented diamond cutting edge and large 102 mm diameter allow creating precise round openings in tiles, sanitary ware and similar brittle materials. The M14 threaded shank enables secure mounting in angle grinders or other compatible rotary tools. When used with water cooling and controlled low-speed feed, the bit reduces chipping and ensures a clean edge around the hole.
Advantages
The diamond cutting segments provide durability and wear resistance when cutting through glazed porcelain and dense ceramics. The wide 102 mm diameter is suitable for common sanitary and tile installation openings. The M14 shank gives a stable connection to rotary tools, reducing wobble and improving accuracy. The design allows efficient removal of material while minimizing thermal stress when water cooling is applied.

Key specifications
 Cutting diameter: 102 mm
 Shank type: M14 threaded shank for angle grinders and compatible rotary tools
 Cutting material: diamond segments bonded for hard ceramics

How to use
Secure the M14 shank firmly in a compatible angle grinder or rotary tool according to the tool manufacturer’s instructions. Mark the drilling position on the porcelain surface and begin at low rotational speed with light, steady pressure. Apply a continuous water feed to the cutting area or use intermittent wetting to keep the diamond segments cool and to reduce dust and chipping. Maintain a perpendicular angle to the surface; avoid heavy pressure or high speeds to prevent cracking. After cutting, allow the material and the bit to cool before removing or cleaning.
Usage recommendations
Use this diamond drill bit with water cooling and low-speed, steady drilling to achieve clean holes and extend tool life. Wear appropriate personal protective equipment, including eye protection and a dust mask when dry cutting; follow the safety instructions of the rotary tool manufacturer.
