Sierra de corona KWB 500314 1,4 cm broca para cerámica

The KWB 500314 1.4 cm Ceramic Drill hole saw is a single-piece cutting tool designed for creating precise holes in ceramic tiles and similar hard glazed materials. With a 1.4 cm diameter it is intended for accurate, clean drilling where a narrow, well-defined opening is required. The tool is made to be used with compatible rotary drills and drill guides suited for tile work.

Advantages

This ceramic hole saw provides precise cutting performance on glazed ceramics and tiles, producing neat round holes with minimal chipping when used correctly. Its single-piece construction reduces wobble and improves concentricity during drilling, helping to maintain accuracy for repetitive tasks. The narrow 1.4 cm diameter is suited to installations that require small, controlled openings without excessive material removal.

How to use

Select a suitable drill with matching arbor or adapter and secure the workpiece to prevent movement. Mark the center point of the hole and, if available, use a drill guide or masking tape to stabilize the hole saw on the glazed surface. Start drilling at low speed with light, steady pressure and keep the cutting area cooled with water to reduce heat and prevent cracking. Increase speed gradually only if the tool and material remain stable; withdraw periodically to clear debris and allow cooling. After cutting, remove any residual slurry and smooth the edge if necessary.

Recommendations

Use continuous water cooling and low to moderate speed for best results; avoid applying excessive axial force. For brittle or very hard tiles, consider pre-drilling a pilot indentation with a carbide or diamond-tipped center bit to improve accuracy and reduce the risk of cracking.
