Precision Drilling Through Delicate Materials With Ease

Calidad Ultra-Thin Wall Hole Saw Bit Set: 1" (25mm), 1 3/8" (35mm), and 2" (50mm) for wet use only. 

Tile, ceramic, and glass drill bits with ultra-thin walls (1mm) deliver a 2x longer lifespan and faster drilling speed on delicate surfaces. 

The key feature of these hole saw bits is their innovative electroplated diamond core, which is significantly thinner compared to other core drills available in the market. This slender wall design not only facilitates more precise cuts but also ensures a superior surface finish with minimal chipping. They are perfectly suited for working with a variety of delicate, hard materials, including optical glass, glass tiles, sheet glass, thin glass, and even slender stone slices.

These drill bits are particularly recommended for use with angle grinders, enhancing their versatility and precision. The suggested RPM range for optimal performance is between 3,500 and 4,500. To ensure both cooling and prolonged life of the hole saw bit, it's essential to use them only with water (Wet Use Only). The high-quality diamonds embedded in these bits enable faster and cleaner drilling, making them ideal for creating clean, precise holes in hard materials.

Disclaimer: These bits are designed for Wet Use Only. Please ensure you do not force the bit down too hard as it may break - let it work with adequate pressure.
