Spoilboard Surfacing Router Bits

Insert-style spoilboard surfacing and slab flattening router bits (KY series): steel bodies with replaceable carbide knives, D 25.4–63.5 mm, 2/3-flute and 2+2 two-stage geometries for CNC bed maintenance. When the knives dull, rotate or replace them on the machine in minutes — the cutting diameter stays constant, so your Z-zero and stepover never need recalibration (the core advantage over brazed surfacing bits, which shrink at every regrind). Rigid machines from 2.2 kW spindle upward; knife packs and spare hardware on each product page. Batch-verified insert hardness.
