10Pcs Diamond Hole Saw Set,1/4"-2" Tile Hole Saw with EVA Mold Guide

The ASNOMY 10-Piece Diamond Hole Saw Set provides a complete kit for drilling clean circular openings in hard, delicate surfaces like ceramic tile, glass, marble, and granite. Built with a solid hardened steel body and a brazed, thickened diamond coating, this set helps users cut smooth, flat-bottom holes without surface chipping.

A standout feature is the unique serrated cutting edge on each core bit. The gaps between the teeth lower cutting resistance while actively clearing chips and debris away from the cut, resulting in faster and more accurate drilling. For positioning, the kit includes a thick EVA mold that protects the bits in transit and doubles as a guide jig fixture to prevent bit walking on slick granite or tile surfaces.

These hole saws undergo a high-temperature resistance treatment that permits direct dry drilling when water is not easily accessible. Even so, using water or another coolant during operation is recommended to extend the overall life of the diamond coating. The package also includes a dedicated storage bag to keep all bits and the guide organized together.

While the set covers a broad range of 10 standard sizes from 1/4 inch up to 2 inches, it does not include bits larger than 2 inches for larger plumbing or vent cutouts. Additionally, the listing does not specify the exact shank type or compatibility with specific drill chuck mechanisms.

Verdict: The ASNOMY 10-Piece Diamond Hole Saw Set is a practical, versatile option for DIYers and installers who need clean, chip-free holes in stone, tile, or glass. It offers great convenience with its dual-purpose guide mold and support for both wet and dry use.
