CRL Port-O-Holer Glass Drill Guide with Vacuum Suction Cup

• Most portable glass drilling tool for on-site hole cutting
• Uses your own cordless or 110V AC power drill (with GFI device)
• Drills up to 2" (51 mm) holes using 3/8" (9.5 mm) shank plated diamond drills

The Port-O-Holer Glass Drilling Tool (SKU: PH1) creates clean, accurate holes up to 2" (51 mm) in glass and mirror — even in awkward or hard-to-reach locations. Designed as a portable glass hole drilling kit, it requires only your cordless or 110V AC power drill, making it a cost-effective solution for installers, glaziers, and DIYers.

Place the Port-O-Holer on the glass, pump the vacuum cup to hold it securely, and use the engraved center reference marks to align holes precisely. Fill the housing with coolant using the included squeeze bottle; the built-in gasket seals to the glass for leak-free drilling. The PH1 ships with a Wood's W4000 8" (203 mm) Lexan handle vacuum cup. Constructed with an all-aluminum frame, the tool weighs just over 3-1/2 lbs.

Key differentiators:

• True portability — use with your own drill for on-site glass drilling
• Vacuum-mounted housing and gasket for stable, leak-free operation
• Center reference marks and included coolant bottle for precise, clean holes

Product Warning:

This tool is to be used on a flat surface only. Always make sure your glass is fully supported before drilling.
