- 4 Inch Diamond Hole Saw: This brazed diamond hole saw is designed for cutting clean 4 inch / 100mm holes in hard materials. The 35mm / 1.38 inch cutting depth makes it suitable for many home improvement, bathroom, countertop, sink, tile and remodeling applications.
- Brazed Diamond Grit for Longer Life: The brazed diamond cutting edge provides stronger diamond retention than standard coated hole saws, helping deliver more durable performance, faster cutting and cleaner holes on ceramic, porcelain tile, marble, granite, quartz and glass.
- Dry Drilling Available: This diamond core drill bit can be used for dry drilling. For harder materials or longer drilling time, adding water is recommended to reduce heat, improve cutting smoothness and extend the service life of the hole saw.
- Includes Center Drill Bit: The removable center drill bit helps guide the hole saw and improves drilling accuracy, especially when starting a hole on smooth tile or stone surfaces. It makes positioning easier and helps reduce slipping during the initial cut.
- Important Use Notes: When drilling without the center drill bit, start at about a 45-degree angle to create a shallow groove, then slowly bring the hole saw upright. Not designed for wood, plastic, metal, iron or steel. Use proper speed, steady pressure and safety protection during operation.
