PCD Diamond Spiral Router Bit 10mm Diameter 16mm Height 12.7mm Shank Diameter for CNC Woodworking

Need a router bit that keeps its edge through MDF, HDF and melamine board instead of being swapped out every shift? This PCD diamond spiral router bit is built for that cut. Cutting diameter 10 mm, cutting height 16 mm, shank diameter 12.7 mm (1/2 inch) — the three numbers that decide whether it fits your collet and your panel thickness. The cutting edges are polycrystalline diamond (PCD), not tungsten carbide, so the resin and mineral filler in engineered panels do not dull them at the same rate. Price on request.

A shop cutting MDF, HDF and melamine board every day runs into the same three problems: carbide bits lose their edge on abrasive glue lines, every tool change is a machine stop, and the last panel of a batch is cut by a duller edge than the first one. A small bit makes the last point worse, because a 10 mm diameter puts a short edge against a lot of abrasive panel.

This is a PCD diamond spiral router bit in size D10 × H16 × S12.7: 10 mm cutting diameter, 16 mm cutting height, 12.7 mm (1/2 inch) shank diameter. The cutting edge is polycrystalline diamond — diamond grit sintered into a solid layer and carried on the tool body — so the part that touches the panel is diamond, not steel. The spiral flute shears the cut instead of chopping it straight, and the 16 mm cutting height matches a 16 mm panel in one pass.

It runs on CNC routers and woodworking machining centers for routing, profiling, slotting and contour cutting. The material list is the abrasive one: MDF, HDF, particle board, melamine board, laminated panels and plywood — six panel families that carry resin and mineral filler. A 12.7 mm shank seats in a 1/2 inch collet with no adapter, so the bit goes from the box into the spindle without extra tooling.

What separates this bit from a standard carbide router bit is the edge material and three fixed dimensions.

• PCD cutting edges — Polycrystalline diamond, not tungsten carbide, is the material in contact with the panel — the point for melamine, MDF and laminated board.
• 10 mm cutting diameter — The D10 body reaches internal radii and narrow slots that a wider cutter cannot enter.
• 16 mm cutting height — 16 mm of usable edge covers a 16 mm panel plus its edge trim in a single pass.
• 12.7 mm (1/2 inch) shank — A 12.7 mm shank is exactly 1/2 inch, so it clamps in a standard 1/2 inch CNC collet with no reducing sleeve.
• Spiral flute geometry — The spiral shears material along the cut instead of striking it square, keeping the load even across the 16 mm edge.
• Six abrasive panel families — MDF, HDF, particle board, melamine board, laminated panels and plywood are all inside the stated application range.
• Four operations on one bit — Routing, profiling, slotting and contour cutting instead of four separate cutters in the carousel.
• CNC router and machining center mounting — Made for CNC woodworking and panel processing machines, the types that hold a 1/2 inch collet.
• One size to reorder — D10 × H16 × S12.7 is the full ordering code — diameter, cutting height, shank; three numbers, no guessing.

The choice today is between a cheap carbide bit you replace often and a diamond bit you buy once per size. For abrasive panel work the second option removes the labour, not just the wear.

• Tool changes stop eating the shift. When a 10 mm carbide bit is swapped twice a shift, the stops cost more than the bit; a PCD edge moves that change interval out to the panel volume you actually run.
• The edge material is the specification. Melamine glue and MDF filler are abrasive; diamond is the harder of the two cutting materials in common use, so the edge geometry survives the run.
• One bit, four operations. Routing, profiling, slotting and contour cutting from a single 10 mm cutter means fewer tools to stock, set and measure.
• The height matches the panel. 16 mm cutting height against a 16 mm panel leaves the trim inside one pass, so the operator is not stacking two cuts to clear one edge.
• No adapter, no runout from a sleeve. A 12.7 mm shank is 1/2 inch, so it seats directly in the collet the spindle was machined for.
• A quote is one message. Price is on request: send the size D10 × H16 × S12.7 and the quantity, and the quotation comes back for that exact configuration.

D10 × H16 × S12.7. That is 10 mm cutting diameter, 16 mm cutting height and 12.7 mm (1/2 inch) shank diameter, and the same three numbers are the ordering code.

Yes, if your spindle takes a 1/2 inch collet. The shank is 12.7 mm, which is exactly 1/2 inch, so no reducing sleeve is needed.

PCD is polycrystalline diamond: diamond grit sintered into a solid layer that becomes the cutting edge. On this bit the diamond layer, not steel or carbide, is the part in contact with the panel.

Yes. The stated application is CNC woodworking and panel processing, and the material list covers MDF, HDF, particle board, melamine board, laminated panels and plywood.

Because the wear comes from the panel, not the wood. Resin and mineral filler in engineered panels abrade a carbide edge; diamond is the harder cutting material, so the edge holds its shape across a longer production run.

Four: routing, profiling, slotting and contour cutting. All four are named in the tool's application range, so the same 10 mm bit covers them.

Yes for panels up to 16 mm thick. The usable edge is 16 mm; a thicker stack or a deeper slot needs a bit with a longer cutting height.

Send the size D10 × H16 × S12.7 and your quantity. Price is quoted on request for that configuration rather than listed as a fixed figure.
