收藏: Diamond Starrett Hole Saws

Diamond Starrett-style hole saws are large-diameter diamond core drilling tools designed for cutting clean, precise holes in stone, glass, ceramic tile, porcelain, and hard minerals. The continuous diamond-coated rim cuts a circular channel through the material, removing a clean core plug and leaving a smooth, chip-free hole edge. Compatible with standard drill presses, angle grinders, and heavy-duty hand drills with water swivel adaptors for continuous coolant flow.

Frequently Asked Questions

• Q: What is a Diamond Starrett Hole Saw used for?
  A: Diamond Starrett hole saws are used for cutting large-diameter holes in stone, glass, tile, and hard minerals — applications where standard drill bits are too small. They cut a circular channel and remove a core plug, making them ideal for plumbing penetrations in tile, decorative stone inlays, and large pendant holes in stone slabs.
• Q: Should diamond hole saws be used wet or dry?
  A: Always use wet. A water swivel adaptor delivers continuous coolant through the hollow shank directly to the cutting rim, preventing overheating and extending saw life. Never run a diamond hole saw dry — heat buildup will rapidly destroy the diamond rim.
• Q: What drill speed should I use with a diamond hole saw?
  A: Use low speed — 300–600 RPM for most stone and tile applications. Apply steady, moderate downward pressure without forcing. Slow, consistent cutting with continuous water cooling produces the cleanest holes and maximum saw life.
