Tungsten Nickel Iron PCD Diamond Router Bit 12mm Cutting Diameter for CNC Woodworking

This PCD diamond router bit is built for the abrasive panels where carbide gives up: 12 mm cutting diameter, 10 mm shank, 25 mm cutting height, 75 mm overall length, Z3+3 cutting configuration, polycrystalline diamond edges on a tungsten nickel iron body, specified for CNC woodworking machinery. It cuts MDF, HDF, particle board, chipboard, melamine board, laminated boards, plywood and veneered panels, so a CNC production line stops changing bits and the edge on the last panel matches the edge on the first. Price on request.

Three things stop a CNC router line: a carbide bit that dulls after a run of abrasive board, a spindle parked mid-shift for the tool change, and a cut edge that chips where the melamine skin lifts. All three trace back to one place — the edge wearing down — and that is what a diamond edge is for.

This is a PCD diamond router bit in D12 x D10 x H25 x L75, Z3+3: 12 mm cutting diameter, 10 mm shank diameter, 25 mm cutting height, 75 mm overall length, polycrystalline diamond edges on a tungsten nickel iron body, specified for CNC woodworking machinery.

The two materials do different jobs. PCD is the cutting material: a sintered diamond layer that resists abrasion where a brazed carbide tip gives up, so the edge keeps its geometry through MDF, HDF, particle board, melamine-faced panels, laminated boards, plywood and veneered panels. Tungsten nickel iron is the body: a high-density matrix that holds the 12 mm head rigid on the end of a 75 mm shank, so the cut stays dimensionally stable instead of springing under load.

The 10 mm shank is the mounting interface — it clamps in the tool holder already on the machine — and 25 mm of cutting height covers a banding rebate in one pass. Z3+3 carries the chip out: six edges, three plus three.

What the numbers on the shank do not say:

• PCD cutting edges. Polycrystalline diamond resists the abrasion that wears a brazed carbide tip out of shape.
• Tungsten nickel iron body. A high-density matrix holds the 12 mm head rigid instead of letting it deflect under load.
• Z3+3 edge layout. Six edges in two groups of three shear the chip and clear it, rather than packing it into the kerf.
• 12 mm cutting diameter. Takes the light radial cut that edge trimming and profile work need.
• 10 mm shank. Clamps straight into a 10 mm collet — no sleeve and no adapter between the bit and the spindle.
• 25 mm cutting height. One setting covers the full height of a banding rebate instead of two passes.
• 75 mm overall length. Long enough that the holder nose clears the panel while the 25 mm cutting head sits fully in the cut.
• Built for abrasive panels. MDF, HDF, particle board, chipboard, melamine board, laminated panels, plywood and veneered panels.
• Fewer tool changes. A diamond edge stays in the spindle while a carbide tip would already be off the machine.
• Specified for CNC. Runs on CNC woodworking machines and machining centres — the application this bit is specified for.

On an abrasive board line the question is not which router bit to buy — it is whether the spindle keeps stopping.

• Tool changes come off the shift. Every stop for a dull bit is machine time you pay for twice; a PCD edge holds its geometry across a run instead of tapering off before the run ends.
• The edge stops depending on how fresh the tip is. A worn carbide tip burns and chips quietly before anyone notices. Diamond wears slowly enough that the first panel and the last one are cut by the same 12 mm geometry.
• One bit covers the panels you actually run. MDF, HDF, particle board, melamine, laminate, plywood, veneer — seven families through one 10 mm shank.
• Your existing holder takes it. The 10 mm shank mounts in the collet already in the spindle, so nothing else has to change to try it.
• Rigidity where the load lands. The tungsten nickel iron body puts mass behind the 12 mm head at the end of 75 mm, so the tool resists deflection at depth.
• Depth in one setting. 25 mm of cutting height means a banding rebate is one pass, not two.
• Price quoted per enquiry. Quotes come back against the diameter, shank and tooth pattern you actually need, rather than a fixed catalogue price.

Abrasive wood-based panels. It is specified for MDF, HDF, particle board, chipboard, melamine board, laminated panels, plywood and veneered panels, and for CNC woodworking machinery in general. It is listed for wood-based panels, not for metal.

Six cutting edges, arranged as two groups of three. Z is the tooth count, so Z3+3 gives you three plus three edges working the cut instead of a single flute, which is the configuration the bit is built around for chip removal.

Yes if your tool holder takes a 10 mm shank. The shank diameter is 10 mm and the bit mounts in a 10 mm collet, so any spindle or holder set up for that shank size can run it.

25 mm. Cutting height is 25 mm on a 75 mm overall length, so a banding rebate or edge pass up to that height is one setting rather than two.

Because PCD wears slower on abrasive board. Polycrystalline diamond is the cutting material here, and it holds an edge where a brazed carbide tip dulls — which is the whole reason the bit exists.

Rigidity and dimensional stability. The body material is tungsten nickel iron, a high-density matrix that keeps the 12 mm head from deflecting at the end of the 75 mm length.

It is specified for CNC woodworking machinery. The bit is built as a 12 mm, Z3+3 production cutter with a 10 mm shank, and the application listed for it is CNC machines and machining centres, not hand-held work.

Ask for a quote. Pricing on this bit is contact-us-for-a-quote rather than a published figure, so send the 12 mm cutting diameter, 10 mm shank and Z3+3 pattern you need and the quote comes back against that specification.
