PCD Compression Spiral Cutter 18.5x112.7xH15 Z2+2 CNC Cutting Tool

Need a clean edge on both faces of a nested melamine panel? This PCD compression spiral cutter cuts them in one pass. 18.5 mm cutting diameter, 112.7 mm overall length, 15 mm cutting height, Z2+2 geometry — two up-cut and two down-cut edges on one body — with polycrystalline diamond as the cutting material. Listed for CNC routing and CNC nesting in MDF, particleboard, melamine, HPL, laminated panels and plywood. Custom sizes quoted on request.

A shop nesting melamine-faced board hits the same three problems. The top face chips where the bit enters, because an up-cut edge lifts the laminate before it shears. The bottom face chips at the vacuum pods, for the mirror reason. And the cutter that fixes both still wears out mid-nest, because a carbide edge rounds over on glue-filled core.

This PCD compression spiral cutter answers all three, and the size string settles fitment first: 18.5x112.7xH15 Z2+2. That is an 18.5 mm cutting diameter, a 112.7 mm overall length, 15 mm cutting height and Z2+2 geometry — two up-cut and two down-cut edges on one body, 4 flutes. The down-cut pair presses the top skin into the core, the up-cut pair lifts the bottom skin, and both faces are cut inward, so neither tears at the exit.

The cutting material answers the third problem. These are PCD edges — polycrystalline diamond, not tungsten carbide — so they keep their shape on the abrasive panels most nesting work uses: MDF, HDF, particleboard, melamine-faced particleboard, HPL, laminated panels and plywood.

It mounts in a CNC router or nesting machine for panel sizing, contour cutting, grooving and profiling, and one pass covers both faces. Customization is supported on diameter, cutting length, overall length, shank, tooth geometry and PCD grade, quoted against your machine model, existing cutter dimensions or a drawing. Price on request.

What separates a compression spiral that cuts clean on both faces from one that does not:

• 18.5 mm cutting diameter. The cutting circle measures 18.5 mm, so nested cut-outs and internal corners come out at the radius the program asks for.
• 112.7 mm overall length. 112.7 mm end to end settles reach and clamp height before an order, not after the first cut.
• 15 mm cutting height. H15 is 15 mm of active flute — the section that cuts, separate from shank and body.
• Z2+2 compression geometry. Two up-cut and two down-cut edges, 4 flutes on one body, so one through-cut is finished on both faces.
• PCD cutting material. Polycrystalline diamond rather than carbide, so the hard material sits exactly where the chip forms.
• Seven panel types. MDF, HDF, particleboard, melamine-faced particleboard, HPL, laminated panels and plywood — the board this cutter is catalogued for.
• CNC routing and CNC nesting. Panel cutting and sizing, contour cutting, grooving and profiling all sit inside the same geometry.
• Helical chip evacuation. The spiral flutes control chip flow out of the kerf, so a deep nested slot stays clear.
• Custom specifications. Diameter, cutting length, overall length, shank, tooth geometry and PCD grade are quoted to your machine.
• One line to reorder. 18.5x112.7xH15 Z2+2 identifies the cutter completely.

When a nesting cutter dulls, the choice is usually a cheaper bit of unknown spec, an edge that needs sanding after the machine, or downtime waiting on a delivery. What this cutter changes:

• Fitment is settled on paper. 18.5 mm diameter, 112.7 mm overall and 15 mm cutting height either match your nest or they do not — you know which before you pay.
• Both faces leave the machine done. 4 opposing edges in one pass means no second operation and no hand-sanding station at the end of the line.
• Diamond lands on the abrasive work. PCD on MDF, melamine and HPL is where the hardness earns its keep, which is most of what a nesting table cuts.
• Fewer tool changes mid-nest. A diamond edge holds its geometry on glue-filled board, so a long nest finishes on the cutter it started with.
• One line to reorder. 18.5x112.7xH15 Z2+2 identifies the cutter completely, so the second order is a copy of the first, not a new drawing.
• Small circle, real radii. 18.5 mm is the cutting circle, so internal corners are cut at the size the program specifies.
• Non-standard sizes quoted. Customization is supported on diameter, cutting length, overall length, shank, tooth geometry and PCD grade.
• Price follows your quantity. Quoted on request rather than listed, so the figure matches the volume you order instead of a single-piece list price.

Yes, if your machine takes an 18.5 mm cutting diameter on a 112.7 mm overall body with 15 mm of flute. Those numbers plus Z2+2 are the whole fitment check — send them with your machine model and you will know before you order.

Two up-cut and two down-cut edges — 4 flutes on one body. The opposing helices cut the top and the bottom face toward the middle of the panel, which is what stops both skins from chipping at the exit.

MDF, HDF, particleboard, melamine-faced particleboard, HPL, laminated panels and plywood. That is the engineered-wood and laminate group this PCD cutter is catalogued for as a compression spiral.

Because diamond holds its shape on abrasive board. PCD keeps a usable edge on glue-filled MDF and melamine where carbide rounds over, and that is the difference between finishing a nest on one cutter and changing mid-run.

Yes. Customization is supported on diameter, cutting length, overall length, shank specification, tooth geometry and PCD grade — send your machine model, your existing cutter dimensions, a drawing or a part number and the specification is confirmed against it.

No. It is catalogued for CNC routing as well as CNC nesting: panel cutting and sizing, contour cutting, grooving and profiling all sit inside the same Z2+2 geometry.

Quoted on request. The price is not listed because it follows the specification and the quantity you order — send the size string 18.5x112.7xH15 Z2+2 with the quantity and the figure comes back to that combination.
