Two Bladed Woodworking Precision Knife

Two-bladed precision knives, SHK 3.175–20 mm, CED 1–20 mm, CEL 4–80 mm. Finish-grade two-flute bits for visible cut faces.

The VPOINT Two Bladed Woodworking Precision Knife is a replaceable-knife cutting tool. Ideal for finish-grade grooving and slotting, visible edge sizing on CNC routers and final sizing before assembly.

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-bladed woodworking precision knife carries two ground flutes on a tungsten carbide body, ground to finish tolerances. Shank diameters (SHK) run 3.175–20 mm, cutting-edge diameters (CED) 1–20 mm, cutting edge lengths (CEL) 4–80 mm and overall lengths (OVL) 38–120 mm, as listed in the specifications table.

How It Works

The precision-ground flutes shear a finish-grade wall: runout is held tight and the edge line is honed for clean shearing rather than fast roughing. Use it where the cut face is visible — revealed edges, finished grooves, final sizing passes before assembly.

Applications

Finish-grade grooving and slotting
Visible edge sizing on CNC routers
Final sizing before assembly
Furniture reveal and detail work

Suitable Materials

Solid wood
MDF and melamine-faced panels
Plywood and veneered panels
Laminated boards

The precision-ground edges hold a finish-grade wall in wood and faced 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.

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.

Performance Data

Standard reference values for guidance only — always adjust to machine rigidity, clamping and tool wear, and confirm on the actual workpiece.

Material	Typical spindle speed	Typical feed	Notes
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
solid wood	15,000–20,000 rpm	4–9 m/min	Grain direction affects finish; climb-cut when possible
hardwood	14,000–18,000 rpm	3–7 m/min	Lower feed in dense grain

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.
