Ingco 50mm Diamond Hole Saw (HSB60502) Premium Industrial Grade Diamond-Coated Core Drill Bit for Glass, Ceramic, and Porcelain Tile

Bore clean, flawless, and perfectly round holes through delicate and ultra-hard surfaces with the industrial-grade INGCO HSB60502 Diamond Hole Saw. Engineered with a 50mm diameter, this professional core drill bit is specifically designed to tackle materials where standard masonry or bi-metal hole saws would fracture, crack, or fail. It is an indispensable tool for kitchen and bathroom plumbers, tiling contractors, and interior renovators who require precision execution when running pipework, installing fixtures, or routing utility lines through premium tile installations.

The cutting rim is heavily embedded with high-grade, premium synthetic diamond grit, bonded securely to a rugged carbon steel body. This diamond-coated edge grinds smoothly through material rather than tearing into it, drastically reducing the risk of chipping, surface cracking, or thermal breakout on expensive workpieces. Forged with side clearance slots, the core bit facilitates rapid slug removal and allows cooling water to flow directly to the cutting zone. When paired with proper water lubrication, this heavy-duty hole saw operates with minimal friction, prevents overheating, and delivers a vastly extended service life with clean, smooth-edged results every time.
