2Z Two Blade Woodworking Composite Knife

2Z composite knives, SHK 3.175–20 mm, CED 3.175–20 mm, CEL 12–72 mm. Carbide bits for composite and laminated panel machining.

The VPOINT 2Z Two Blade Woodworking Composite Knife is a replaceable-knife cutting tool. Ideal for composite and laminated panel cutting, nested-based manufacturing and panel furniture machining.

Product Description

Design and Construction — a VPOINT router bit tool for CNC routing and nesting, sized for MDF and similar workpieces. The specification table below lists dimensions; the performance data table gives standard reference speeds and feeds to start with, and the FAQ covers selection, parameters and service. ISO 9001 production, batch-verified, custom sizes from drawings.

Design and Construction

The two-blade woodworking composite knife carries two flutes on a tungsten carbide body for composite and laminated panel machining. Shank diameters (SHK) run 3.175–20 mm, cutting-edge diameters (CED) 3.175–20 mm, cutting edge lengths (CEL) 12–72 mm and overall lengths (OVL) 45–130 mm, as listed in the specifications table.

How It Works

The two-flute geometry shears laminated and composite panels without lifting the face layer, and the matched flute count balances chip load for panel work. Edge diameters equal to shank diameters in most part numbers give maximum rigidity at the cutting point.

Applications

Composite and laminated panel cutting
Nested-based manufacturing
Panel furniture machining
Sizing and shaping on CNC routers

Suitable Materials

Laminated and composite panels
MDF and melamine-faced boards
Particleboard
Plywood

The matched flute geometry keeps the face layer intact and the cut width constant in composite panels.

Material Comparison: Tungsten Carbide vs. PCD

The figures below are typical industry data for CNC tooling. Tungsten carbide is the economic standard for general CNC routing — tough, regrindable and available in every geometry. PCD wins on very high-volume abrasive work; this page covers the carbide line, and the comparison shows where each material wins so you can match the tool to the job.

Property	Tungsten Carbide (This Tool)	PCD Diamond
Hardness	1,500–2,000 HV	7,000–9,000 HV
Tool life on MDF / particleboard / melamine	30–60 h (baseline)	15–20× longer (500–1,200 h)
Tool life on solid hardwood	80–150 h (baseline)	10–13× longer (800–2,000 h)
Edge renewal	4–6 regrinds at shorter intervals	5–8 regrinds, each removing only 0.2–0.3 mm of diamond
Surface finish	Ra ~0.8 μm typical, degrades as the edge wears	Ra ≤ 0.2 μm achievable, stable over the tool life
Thermal conductivity	~80 W/m·K	540–560 W/m·K — heat leaves the edge fast
Friction coefficient	≈ 0.3	≈ 0.05 — lower cutting forces
Fracture toughness	Higher — tolerates interrupted cuts and impacts better	Lower — needs stable, vibration-free setups
Suited for	General-purpose CNC routing in wood, panels, acrylic; the economic standard	Very high-volume abrasive panel work; non-ferrous metals

Figures are typical published values; actual tool life depends on the workpiece material, feed rate, depth of cut, machine condition and maintenance schedule.

Delivery Scope

Single cutter. Order by part number with the shank, cutting-edge diameter and cutting length stated in the specifications table below.

Why Choose VPOINT

One-year warranty on every cutter — defects in material or workmanship are covered for 12 months from delivery.
Custom tooling — diameters, shanks, cutting lengths and flute configurations built to your drawing or sample.
Non-standard fabrication — sizes outside the standard catalogue, including special geometries.
Resharpening service — cutters return to service after regrinding at a fraction of new-tool cost.
Factory-direct since 2008 — ISO 9001 manufacturing in Sichuan and Dongguan, China; no trading intermediaries.

Send a drawing, a sample or a worn tool, and our engineering team will quote the exact specification you need.

Precision & Quality Control

Every cutter is inspected before shipment. Shank diameter, cutting-edge diameter, cutting length and overall length are measured against the values listed in the specifications table, and cutting edge runout is verified on the assembled tool.

Tools measuring outside tolerance do not ship. Inspection is performed under our ISO 9001 quality system, with batch records retained for traceability.

MDF	18,000–22,000 rpm	6–10 m/min	Nesting and grooving; watch heat at small diameters
particleboard	16,000–20,000 rpm	5–8 m/min	Reduce feed if the face starts to chip
plywood	16,000–20,000 rpm	5–8 m/min	Keep the compression or shear geometry inside the panel
veneered board	18,000–20,000 rpm	5–7 m/min	Light finish passes protect the veneer
hardwood	14,000–18,000 rpm	3–7 m/min	Lower feed in dense grain
laminated board	16,000–20,000 rpm	5–8 m/min	Melamine faces chip easily; sharp edges only

Frequently Asked Questions

What finish can I expect on the edge?

With sharp knives and a stable feed the edge comes off clean enough to skip sanding on most boards; test on offcuts first.

How often should I rotate or replace the knives?

Rotate at the first sign of fuzzing or burn; a fresh edge costs less than a rejected panel.

Any special clamping notes?

Seat the knife fully, torque evenly and re-check after the first minute of cutting.

Where do these reference values come from?

They are standard reference ranges for this tool family, compiled from our specification sheets and common workshop practice — always confirm on the actual workpiece.
