Indexable Insert Surfacing & Facing Bits
Get a flawless flat finish in fewer passes. These indexable insert router bits are built for surfacing and facing work — flattening spoilboards, levelling timber slabs and epoxy river tables, and cleaning up large flat areas on your CNC. The wide cutting diameter clears more material per pass than a standard end mill, so big jobs go faster and finish smoother.
The real advantage is the replaceable carbide insert. Instead of throwing out a whole dull cutter, you simply rotate the insert to a fresh edge or drop in a new one — you're back to a factory-sharp cut in seconds, for a fraction of the cost of a new tool. One body lasts for years; only the cheap inserts are consumable.
Precision-ground carbide inserts leave a clean, tear-free surface across hardwood, softwood, MDF, plywood and cured epoxy, with the larger diameters ideal for slab flattening and spoilboard resurfacing.

Frequently asked questions
What is an insert surface planer for?
Fast spoilboard resurfacing, flattening timber slabs and finishing epoxy river tables. Its wide cutting diameter covers far more area per pass than an end mill.
Why replaceable inserts?
When an edge dulls you rotate the carbide insert to a fresh edge or fit a new one, instead of buying a whole new cutter. Replacement inserts are listed in the size options.
What materials can it surface?
Hardwood, softwood, plywood, MDF / HDF and cured epoxy.
Which size suits my machine?
The 25.4mm and 39mm heads are on a 6.35mm (1/4") shank for smaller routers. The 50.8–76.2mm heads are on a 12.7mm (1/2") shank for spindles that can take a 1/2" collet.
