## Summary description

Diamond hole saw by GRAPHITE, diameter 16 mm with M14 thread (model 55H304). Designed for drilling precise holes in hard materials where diamond grit cutting is required. Fits M14-shank angle grinders or compatible rotary tools. Suitable for ceramics, tile, glass and similar surfaces for installation, renovation and repair tasks.

## Long description

Diamond Hole Saw GRAPHITE 16 mm M14 (model 55H304) is a diamond-grit cutting cup designed for drilling precise small-diameter holes in hard and brittle materials. It is intended to be mounted on tools with an M14 threaded arbor and delivers concentrated cutting action for clean penetrations through ceramics, porcelain, glass and similar surfaces. The 16 mm diameter provides a compact cutting profile suitable for plumbing, electrical and finishing installations where accurate small holes are required.
Advantages
The diamond-coated rim ensures high abrasive performance on hard materials while reducing chipping around the hole edge. The M14-compatible thread provides secure mounting to angle grinders and compatible rotary tools, enabling stable rotation and controlled progress. The small 16 mm size gives precise results with minimal material removal and reduced risk of cracking when used with appropriate feed rate and coolant. The construction balances cutting speed and durability for repetitive small-hole drilling tasks.
Suitable for
Drilling holes in ceramic and porcelain tiles for fixtures and fasteners
Cutting small-diameter openings in glass for fittings and conduits
Creating precise penetrations in bathroom and kitchen renovation work
Plumbing and electrical installations requiring 16 mm holes
Key specifications
Cutting type: diamond grit rim for abrasive cutting
Hole diameter: 16 mm
Mounting thread: M14 compatible
Intended materials: ceramics, porcelain, glass and similar brittle/hard surfaces
Tool compatibility: angle grinders and rotary tools with M14 arbor
How to use
Mark the drilling position and secure the workpiece to prevent movement. Fit the hole saw onto a tool with an M14 threaded arbor, ensuring it is tightened correctly. Start drilling at low speed to establish the cut, then increase speed moderately while applying steady, light pressure. Use a coolant or water to reduce heat and remove debris, especially when working on glass or porcelain. Withdraw periodically to clear slurry and check progress; avoid forcing the tool to prevent cracking of the material.
Usage recommendations
Use continuous water cooling or intermittent wetting to extend tool life and improve hole quality. For best results on tiles and glass, begin drilling at an angle or use a guide to prevent wandering, then straighten the tool once the rim has seated. Wear appropriate eye, hand and respiratory protection when cutting, and clamp fragile workpieces securely.
