18mm CNC Machine Table T-Slot Covers – PETG Snap-In Swarf Guard

Keep packed swarf, razor-sharp hot chips, and thick coolant sludge out of your machine bed with these custom 3D-printed 18mm T-slot cover strips. Engineered specifically to eliminate tedious slot cleaning during setups, these covers press directly into your table slots from above—preventing metal chips from jamming T-nuts and damaging ground table surfaces.

Key CNC Engineering Features & Field Benefits

• Precision 18mm Machine Fitment: Engineered specifically for standard 18mm bed slots found on commercial CNC machining centres, Bridgeport-style manual mills, and heavy-duty drilling beds.
• Drop-In Snap-Fit Installation: Features an engineered flex-leg design that snaps directly into the upper slot neck from above—no need to slide long strips in from the table ends or clear surrounding vices.
• Flush Bed Profile: Sits completely flush with the ground machine bed, allowing stock, fixtures, and parallels to slide smoothly across the table without snagging or catching.
• Easily Trimmed to Custom Lengths: Easily trimmed using a utility knife, shears, or fine saw to fit around vices, rotary tables, sub-plates, and fixture plates.
• Oil & Coolant-Resistant PETG: 3D-printed in high-impact industrial PETG polymer that resists synthetic coolants, cutting oils, tramp oil, and hot chips without degrading, warping, or turning brittle.
• 30+ Years Toolroom Heritage: Designed and manufactured in the UK by a production engineer with over 30 years of CNC machining and toolmaking experience.
