Priced to your specification — we do not work from a price list. A 150 mm wheel for 4 mm float glass and the same size for 19 mm laminated glass are not the same product. Tell us the machine and the glass, and the quote will be for what you actually need.

Why this wheel

Optional companion to the 3–150 mm glass drill bits — full range coverage.

One pass after drilling chamfers the rim; no chipping on 3–150 mm holes.

Fits glass drilling machines and bench drills; swaps with the bit.

Glass countersink sleeves are the optional companion to our diamond drill bits: once the hole is drilled, a pass with the countersink chamfers the hole edge and forms the countersink, so the rim does not chip during handling and fitting. Sleeve sizes are matched to the drill bits, covering the 3–150 mm range; special sizes are made to drawing. They fit glass drilling machines and bench drills and swap with the bit.
