Hole Saw KWB 500312 1.2 cm for Ceramic Granite Marble

The KWB 500312 1.2 cm hole saw is a single-piece cutting tool engineered for drilling precise small-diameter holes in hard surfaces such as ceramic, granite, marble, stone and various tile types. Its 1.2 cm diameter makes it suitable for tasks that require compact, accurate openings — for example, for plumbing lines, anchors, cable passages or fixture mounting. The construction focuses on stability and controlled material removal to reduce chipping on fragile surfaces.

Advantages

This hole saw combines a compact diameter with a rigid single-piece design to deliver consistent circular holes with minimal vibration. The cutting edge and geometry are optimized for use on hard and brittle materials, helping to limit micro-fractures and edge breakage. Its compatibility with common drill chucks and straightforward attachment makes it practical for both professional tradespeople and DIY users who need small, accurate holes.

Key specifications

How to use

Mark the drilling point on the workpiece and secure the material to prevent movement. Fit the hole saw into an appropriate drill chuck and set the drill to a moderate speed. Apply steady, even pressure and keep the drill perpendicular to the surface to maintain a clean circular cut. For ceramic, marble and similar brittle materials, use light feed force and consider starting with a pilot guide or using masking tape over the mark to reduce slippage. Periodically withdraw the tool to clear dust and avoid overheating; cooling with water can be used if compatible with the worksite and material.

Recommendations

Use the 1.2 cm hole saw with a drill that offers speed control; begin at low speed and increase only if cutting remains stable. Wear appropriate personal protective equipment, clamp the workpiece, and consider using water cooling when drilling extended holes in stone or ceramic to reduce heat and prolong tool life.
