Keep Machine T-Slots Free of Swarf, Hot Chips, and Coolant Sludge

Cleaning packed swarf and thick coolant sludge out of mill table T-slots burns valuable machine time during setups. Aluminum and steel chips wedged inside slots can damage T-nuts, ruin clamping setups, and score precision table surfaces when moving vices or rotary tables.

Designed and manufactured in the UK by an engineer with over 30 years of CNC machining and toolroom experience, these 18mm T-slot covers provide a clean, flush barrier across your machine bed. Featuring an engineered flex-leg design, these covers press directly into the slot from above with a firm snap fit—eliminating the need to slide long strips in from the ends of the table.

Key CNC Engineering Features & Field Benefits

• Precision 18mm Machine Fitment: Specifically engineered for standard 18mm bed slots found on most commercial CNC machining centres, Bridgeport-style manual mills, and heavy-duty drilling beds.

• Drop-In Snap-Fit Installation: Simply align the cover over the slot and push down. The spring-action side legs snap into the upper slot neck, holding the cover firmly flush without lifting under heavy coolant spray.

• Flush Table Surface Profile: Sits completely flush with the ground machine bed, allowing stock, fixtures, and parallels to slide smoothly across the table without snagging.

• Easily Trimmed to Custom Lengths: Can be cut cleanly to fit around vices, sub-plates, or rotary tables using a standard utility knife, shears, or fine-toothed saw.

• Oil & Coolant-Resistant PETG Construction: 3D-printed using high-impact PETG polymer that resists cutting oils, water-soluble coolants, tramp oil, and hot chips without warping or becoming brittle.
