Cosmo Stubbing Wheels

Prepping recessed drainers, sinking out massive internal sink structures, or calibrating uneven slabs down to a uniform thickness puts immense structural pressure on CNC machinery. The Cosmo Collection Universal Segmented Stubbing Wheels are high-production milling tools engineered to rapidly evacuate vast amounts of stone material while keeping the milled pocket base completely flat and level.

By clearing away the heavy stock out of a recess area, these wheels create an accurately calibrated surface that protects subsequent profile and diamond polishing wheels from premature, uneven wear. Whether milling abrasive quartz networks or dense natural granites, the segmented configuration ensures clean, continuous cutting action without burning the stone or bogging down the spindle, giving fabricators a highly stable, fast-milling setup.

Technical Features

• Universal Material Bond: A highly versatile diamond segment composition formulated to cut smoothly through hard granites, quartz, and engineered stone without glaze buildup.

• Heavy Stock Removal Dynamics: Explicitly balanced to handle demanding material removal (ranging from 1mm up to 5mm depth per pass depending on machine settings), accelerating production times.

• Dual-Diameter Precision Sizing: Offered in an 87mm diameter for fast, expansive open-recess milling, and a compact 50mm diameter for navigating tighter inside radii and smaller vanity configurations.

• Flange Bore Geometry: Features a industry-standard 50mm centre bore configuration with 3 reversible holes, mounting seamlessly onto standard 1/2″ Gas or 35mm CNC cone adapters.

• Optimised Operational Balance: Precision-engineered to eliminate tool vibration at recommended running outputs (4,300–4,800 RPM), guaranteeing scratch-free, flat surfaces.

Tool Application Style

• CNC Worktops & Recess Drainers: The definitive choice for modern automated fabrication shops creating recessed drainer boards, flush-fit hobs, and deep-pocket vanity undermount alignments.

• Slab Calibration & Levelling: Essential for squaring up variable slab boundaries to precise, unvaried operational thicknesses before running automated edge-polishing routines.
