Gatenzaag KWB 500306 6 mm voor keramiek graniet marmer

The KWB 500306 6mm hole saw is designed for drilling precise small-diameter holes in hard surfaces such as ceramic, granite and marble. Intended as an accessory for handheld drills and drill stands, this 6mm cutting tool provides a compact solution for tasks that require accuracy and clean edges. The construction balances hardness and wear resistance to maintain cutting performance during repeated use on dense materials.

Advantages

This 6mm hole saw delivers accurate, round holes with minimal chipping on brittle surfaces thanks to a cutting edge optimized for hard materials. The tool’s durable construction extends service life when used correctly and reduces the need for frequent replacements. Its small diameter supports fine, detailed work and allows installation of fixtures or passage of small conduits without excessive material removal.

How to use

Secure the hole saw in a compatible drill chuck or arbor and ensure the workpiece is firmly clamped or supported. Mark the drilling point and start at a low speed to establish the cut without slipping. Apply steady, moderate pressure and increase speed gradually as the cutter engages the surface. For ceramic and other brittle materials, use a backing support where possible to reduce chipping at exit. Periodically withdraw the cutter to clear debris and, if appropriate, use light water cooling to reduce heat buildup and extend tool life.

Recommendations

Use eye protection and gloves when drilling. Match drill speed and pressure to the material hardness, and avoid excessive force that can cause cracking. If uncertain, test on a scrap piece of the same material before working on finished surfaces.
