Edgetooth Milling Cutter (Corn Milling Cutter)

Corn milling cutters (edgetooth), SHK 3.175–12 mm, CED 0.4–12 mm, CEL 3–62 mm. Serrated carbide edges for fast roughing in wood and board.

The VPOINT Edgetooth Milling Cutter (Corn Milling Cutter) is a long-reach corn milling cutter. Ideal for roughing passes on CNC routers, deep profiling in thick panels and panel sizing and shaping.

Product Description

Design and Construction — a VPOINT end mill tool for CNC milling, 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 corn milling cutter (edgetooth milling cutter) carries a serrated tungsten carbide cutting edge. Shank diameters (SHK) run 3.175–12 mm, cutting-edge diameters (CED) 0.4–12 mm, cutting edge lengths (CEL) 3–62 mm and overall lengths (OVL) 38–100 mm; the edge specification (Z) for each part number is listed in the specifications table.

How It Works

The serrated edge breaks the chip into small segments instead of one long curl, so the cutter can take aggressive roughing passes in dense board without loading. Each serration acts as its own cutting point, spreading wear and keeping feed force low through deep passes.

Applications

Roughing passes on CNC routers
Deep profiling in thick panels
Panel sizing and shaping
Fast stock removal in wood and board

Suitable Materials

MDF and particleboard
Solid wood
Plywood and engineered panels
Laminated boards

The serrated edge keeps feed force low and chip clearance high through deep roughing passes.

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.

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.

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

Why the wavy (wave/corn) tooth design?

The staggered teeth split long chips into short ones, so the feed stays stable and the groove floor stays clean.

Which materials suit the toothed edge best?

Dense boards and laminates — MDF and similar — where plain flutes load up. Begin near 18,000–22,000 rpm / 6–10 m/min.

How do I extend edge life?

Keep the feed constant, avoid dwelling, and clear dust from the groove; packed dust heats the edge.

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.
