Eliminate stuck core plugs entirely. Achieve perfectly clean, chip-free anchor and plumbing holes in marble and granite.
Dealing with wedged stone plugs inside a hollow barrel slows down production and risks fracturing expensive slabs. The Premium Red Non-Core Bits feature a solid, continuous-grinding head design that pulverizes the entire stone area into slurry instead of cutting a core ring. Engineered specifically for high-precision wet operation, these bits deliver an incredibly smooth, vibration-free drilling cycle. They are the ultimate choice for fabricators who need to drill pristine blind holes for mechanical anchors, clean undermount sink clips, or fast plumbing lines through natural granite and delicate marble with zero blowout risk.
100% Core-Plug Free Operation: Because the solid diamond matrix grinds away the entire volume of the hole, there is absolutely zero downtime spent hammering out stubborn, stuck stone plugs.
Chip-Free Precision on Marble: The continuous solid diamond head geometry drastically reduces edge vibration, allowing clean entry and exit cuts even on highly fragile natural marbles and softer travertines.
Maximum Flow Wet Optimization: Engineered strictly for wet use to ensure continuous thermal cooling and instant slurry flushing, drastically extending the bit's operational cutting life.
Rock-Solid Dynamic Balance: The heavy-duty solid-center design distributes torque evenly across the machine shaft, eliminating the bit "wandering" or skidding when starting a fresh hole.
Seamless Angle Grinder Threads: Equipped with a standard industrial 5/8"-11 female thread that spins directly onto standard electric or pneumatic right-angle grinders and variable-speed stone polishers without requiring adapters.
