## Long description

Diamond hole saw GRAPHITE OTWORNICA, diameter 68 mm with M14 threaded shank (model TOP-55H315) is a cutting accessory designed for creating precise circular openings in hard surfaces. The tool's diamond cutting edge enables efficient removal of material when working with ceramics, tiles, porcelain and glass. It is intended for use with hand-held rotary tools and angle grinders equipped with an M14 mount, providing a stable connection for controlled drilling.
Advantages
The diamond-embedded rim delivers high abrasion resistance and consistent cutting performance when drilling brittle or glazed surfaces. The 68 mm diameter is suitable for mid-sized penetrations while the threaded M14 shank ensures secure attachment to compatible rotary tools and grinders. The saw's construction supports controlled cutting with minimal chipping when used with appropriate technique and speed.
Suitable for
 Drilling holes in ceramic wall and floor tiles
 Creating openings in porcelain sanitary ware and sinks
 Cutting circular holes in glass panels and mirrors (with proper cooling and support)
 Preparation of penetrations for pipes, conduits or fixtures in tiled surfaces
Key specifications
 Cutting diameter: 68 mm
 Shank/thread type: M14 threaded mount for rotary tools and angle grinders
 Cutting edge: diamond-coated rim for hard and brittle materials
 Intended materials: ceramics, tile, porcelain, glass and similar surfaces
 Tool compatibility: handheld rotary tools and angle grinders accepting M14 mounts
How to use
Mark the hole center on the workpiece and secure the material to prevent movement. Fit the diamond hole saw onto the tool via the M14 thread and tighten according to the tool manufacturer's instructions. Begin drilling at low speed to establish a pilot groove, then increase speed moderately while maintaining steady, even pressure. Use intermittent operation or continuous water cooling when working with glass and porcelain to reduce heat and prolong the diamond edge life. Avoid applying excessive axial force; let the diamond rim do the cutting.
Usage recommendations
For best results, clamp or support fragile materials, use water as coolant when possible, start drilling at low speed, and avoid side loads. Use appropriate personal protective equipment such as eye protection, gloves and dust control measures. Verify that the selected rotary tool accepts M14-threaded accessories before use.
