Key benefits 50.8mm cutting diameter for fast surfacing over large flat areas. 4 replaceable carbide inserts for practical maintenance and extended cutter body life. Produces a flat, clean finish when levelling spoilboards, slabs and timber panels. Ideal for CNC surfacing of MDF spoilboards, hardwood slabs, softwood, plywood and timber-based sheet materials. Wide planer head reduces machining time compared with smaller-diameter router bits. Great for spoilboard resurfacing, board levelling, slab flattening and surface preparation. 12mm shank for strong tool holding in suitable CNC router collets. Uses 12x12 replacement inserts, sold separately for easy cutter maintenance. .atlas-spec-table-wrap { padding: 5px; margin: 30px 0 0; border: 1px solid #000; border-radius: 16px; overflow: hidden; background: #161616; box-shadow: inset 0px 1px 2px rgba(255,255,255,0.5), inset 0px 1px 2px rgba(255,255,255,0.5), 5px 8px 10px rgba(0,0,0,0.5), 0 0px 1px rgba(0,0,0,0.5); } .atlas-spec-table { width: 100%; border-collapse: separate; border-spacing: 0; border: 0; margin: 0; background: transparent; } .atlas-spec-table th { background: #dca101; color: #000000; text-align: left; padding: 14px 16px; font-size: 14px; font-weight: 800; } .atlas-spec-table th:first-child { border-top-left-radius: 12px; border-right: 1px solid rgba(0,0,0,0.2); } .atlas-spec-table td { padding: 14px 16px; border-top: 1px solid rgba(255,255,255,0.08); } .atlas-spec-table td:first-child { width: 42%; border-right: 1px solid rgba(255,255,255,0.08); color: #f2f2f2; font-weight: bold; } .atlas-spec-table td:last-child { color: #d6d6d6; } .atlas-spec-table tbody tr:nth-child(odd) td { background: #1f1f1f; } .atlas-spec-table tbody tr:nth-child(even) td { background: #161616; } .atlas-spec-table th:first-child { border-top-left-radius: 12px; } .atlas-spec-table th:last-child { border-top-right-radius: 12px; } Spec Result Cutting Diameter 50.8mm Shank / Collet Size 12mm Insert Quantity 4 inserts Insert Size 12x12mm Insert Type Replaceable carbide inserts Application Surface planing, spoilboard surfacing, slab flattening and board levelling Suitable Materials MDF, plywood, hardwood, softwood and timber-based sheet materials Replacement Inserts Sold separately .atlas-btn { display: inline-block; padding: 12px 22px; background: #dca101; color: #000000 !important; font-weight: 800; text-decoration: none; border-radius: 10px; box-shadow: inset 0px 1px 2px rgba(255,255,255,0.4), 3px 5px 8px rgba(0,0,0,0.5); transition: all 0.2s ease; } .atlas-btn:hover { background: #f2b705; transform: translateY(-2px); box-shadow: inset 0px 1px 2px rgba(255,255,255,0.5), 5px 8px 12px rgba(0,0,0,0.6); } .atlas-btn:active { transform: translateY(0px); box-shadow: inset 0px 2px 3px rgba(0,0,0,0.5); } Need 12x12 replacement inserts? Use this Product → Replaceable 12x12 insert system The cutter body uses four 12x12 carbide inserts. When an edge becomes worn, the inserts can be rotated or replaced instead of replacing the full surface planer body. This makes the tool practical for regular spoilboard surfacing, timber flattening and workshop levelling work. Use shallow passes and stable workholding for the cleanest finish, especially when flattening uneven slabs or resurfacing worn spoilboards. Versatility and benefits This surface planer is suited to CNC users who need to flatten slabs, clean up glued panels, resurface spoilboards, level MDF sheets or prepare timber before finishing. The wide 50.8mm cutter head removes material efficiently, while the 12mm shank provides a strong setup for suitable CNC routers. Show more
