Lenox Diamond Grit Precision Hole Saw for Tile & Glass

The Lenox Diamond Grit Precision Hole Saw line brings a diamond-grit cutting edge to hole-cutting tasks that standard twist bits and conventional steel hole saws struggle to handle cleanly. Offered across the 12117-22DGHS, 121074DGDS, 121085DGDS, and DG models, this family covers a range of precision cutting diameters, including a compact 1/4-Inch (6.4mm) option, so tradespeople and DIY users can match the right hole saw to the job at hand. Each model is compatible with standard hole saw mandrels and is engineered as a focused, single-purpose cutting tool rather than part of a multi-size kit, delivering clean, accurately sized holes in materials like tile, glass, and stone.

Key Features

  • Diamond-Grit Cutting Edge: Constructed with diamond grit abrasive material engineered to resist wear and maintain cutting performance longer than conventional tooth-style hole saws.
  • Purpose-Built Hole Saw Design: Designed specifically as a hole saw rather than a general-purpose bit, producing clean-edged, accurately sized holes in a single pass.
  • Standard Mandrel Compatibility: Works with standard hole saw mandrels for straightforward setup and use.
  • Compact, Detail-Ready Profile: Smaller diameter options in the lineup, such as the 1/4-Inch (6.4mm) size, allow access to tight work areas and precise layouts that larger hole saws cannot reach.
  • Model Lineup for Precision Sizing: Available as the 12117-22DGHS, 121074DGDS, 121085DGDS, and DG models, including a 1/4-Inch (6.4mm) diameter option for detail work.
  • Durable Lenox Construction: Manufactured by Lenox, a recognized name in professional-grade cutting tools, built for dependable performance on demanding jobs.
  • Consistent Cutting Performance: The diamond-grit design is intended to provide repeatable cutting results across multiple uses without rapid dulling.

Lenox DG – Frequently Asked Questions

1) What cutting diameters does the Lenox diamond grit hole saw come in?
Four sizes: 3/16 inch (4.8 mm), 1/4 inch (6.4 mm), 5/16 inch (7.9 mm), and 1-3/8 inch (34.9 mm). The part numbers run DG for 3/16, 121074DGDS for 1/4, 121085DGDS for 5/16, and 12117-22DGHS for 1-3/8. Each is a single-size saw, not a kit, so pick the diameter the hole has to end up at.
2) Will a regular bi-metal hole saw cut ceramic tile, or do I need the diamond grit one?
Use the diamond grit. Tile, glass and stone are brittle and abrasive, which chips out and dulls tooth-style bi-metal or carbide-tipped saws fast. The Lenox diamond grit saw cuts with a bonded abrasive edge instead of teeth, so it grinds through the glaze and body without chipping the face, and it holds up over repeat cuts.
3) Does the Lenox diamond grit hole saw need a special mandrel or arbor?
No. It takes standard hole saw mandrels, so if you already have an arbor for your bi-metal saws you can run these on it. Budget for water or coolant at the cut, which is normal practice with any diamond abrasive saw in tile or glass.
4) Which size do I need to drill tile for a toilet supply line or a small anchor?
For small fastener and anchor holes through tile, the 3/16 inch (4.8 mm), 1/4 inch (6.4 mm) and 5/16 inch (7.9 mm) sizes cover the usual plastic and toggle anchor range. The 1-3/8 inch (34.9 mm) size is the one for passing a supply stub, shower valve nipple or cable through a tiled wall. Match the saw to the finished hole you want, since each is one fixed diameter.
5) Can I use this on glass without cracking it?
Glass and other brittle materials are a stated application for the Lenox diamond grit saw. The abrasive edge removes material rather than biting into it, which is what keeps glass and glazed tile from spalling. Keep the pressure light and the cut wet, and start the saw at a slight angle before bringing it flat so it does not skate.
6) Is this the right tool for cutting a hole in tile for an outlet or switch box?
For a device box in tile or stone you need a rectangular cutout, so a hole saw of any kind only gets you the corner relief holes. The 1-3/8 inch (34.9 mm) diamond grit saw is sized for round penetrations, running cable or a conduit stub through a tiled surface. For the box opening itself you want a diamond blade in an angle grinder or an oscillating tool.
7) Is there a pilot bit with the Lenox diamond grit hole saw?
These are abrasive-rim saws with no pilot drill, which is deliberate: a pilot bit would crack tile or glass. Centering is done with the arbor and a steady start, or with a suction guide or template if you are drilling a polished face.
