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.

The VP0062 pre-milling cutter series carries PCD cutting edges on steel bodies for edge banding pre-mill stations, from 50 to 125 mm diameter with 2+2Z two-stage tooth designs and total tooth counts of six to twelve. Cutters are built to the station’s bore, width and tooth pattern.

Design and Construction

The VP0062 pre-milling cutter series carries PCD cutting edges on steel bodies for edge banding pre-mill stations. Part numbers cover diameters from 50 to 125 mm (SIZE format D*bore*H) with two-stage 2+2Z tooth designs, total tooth counts of 6 to 12, and a 30° angle (a°) listed for all rows in the specifications table.

How It Works

The two-stage 2+2Z design cuts the panel edge in one pass — one tooth group takes the roughing cut, the other finishes the edge face. The 30° edge geometry shears the melamine face cleanly, and the PCD tips hold both stages through abrasive board at line speed.

Applications

Pre-milling on edge banding machines
Edge preparation before banding
Small and large panel lines
Panel furniture production

Suitable Materials

Melamine-faced particleboard
MDF and laminated boards
Veneered plywood
Solid wood edge panels

The PCD edges hold the two-stage geometry in abrasive boards, keeping the milled edge consistent across shifts.

Material Comparison: PCD vs. Tungsten Carbide

The figures below are typical industry data for production woodworking. PCD does not replace carbide in every job — carbide remains the right choice for steel, cast iron and low-volume general work — but on abrasive sheet goods the difference in service life is decisive.

Property	PCD Diamond (This Tool)	Tungsten Carbide
Hardness	7,000–9,000 HV	1,500–2,000 HV
Tool life on MDF / particleboard / melamine	15–20× longer (500–1,200 h)	30–60 h (baseline)
Tool life on solid hardwood	10–13× longer (800–2,000 h)	80–150 h (baseline)
Tool life on acrylic / plastics	10–15× longer (1,000–3,000 h)	100–200 h (baseline)
Resharpening cycles	5–8 regrinds (thick tips up to 10); each pass removes only 0.2–0.3 mm of diamond	4–6 regrinds, each removing more material
Surface finish	Ra ≤ 0.2 μm achievable, stable over the tool life	Ra ~0.8 μm typical, degrades as the edge wears
Thermal conductivity	540–560 W/m·K — heat leaves the edge fast	~80 W/m·K
Friction coefficient	≈ 0.05 — lower cutting forces	≈ 0.3
Suited for	Abrasive engineered wood, laminates, composites, plastics, non-ferrous metals	General-purpose; the only choice for steel and cast iron

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, bores, cutting widths and tooth counts built to your drawing or sample.
Non-standard fabrication — profiles and sizes outside the standard catalogue, including profile restoration.
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; 40Cr chrome-molybdenum steel bodies; 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 at micron level before shipment. Cutting diameter (ØD), bore (Ød), cutting width/height (B/H) and overall dimensions are measured against the values listed in the specifications table, and cutting edge runout and concentricity are verified on the assembled tool.

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

Frequently Asked Questions

What is the Pre-Milling Cutters used for?

The VP0062 pre-milling cutter series carries PCD cutting edges on steel bodies for edge banding pre-mill stations.

How do I choose the right size?

Refer to the specification table on this page: part numbers fix the cutting diameter, shank and cutting length. State the diameter, shank and cutting length you need when ordering.

Which materials does it suit?

Typical materials include Melamine-faced particleboard, MDF and laminated boards, Veneered plywood. Confirm the material grade and machining conditions for the specific tool before ordering.

Can I order a custom version?

Yes. Send the profile drawing or item code together with the workpiece material, machine model, cutting direction and quantity. Tools are produced to order, and each tool is packed in an individual plastic box.

What spindle speed and feed should I set for premilling MDF?

＋Start near 20,000–24,000 rpm spindle speed with the edge bander feed around 12–18 m/min, then fine-tune so the premill removes the saw overhang and old glue line in one clean pass.

Why PCD instead of brazed tungsten carbide for premilling?

＋On abrasive MDF and particleboard, PCD edges last 10–20 times longer (typical industry data cited in our comparison table above), so the bander runs far longer between tool changes.

How often should the premill knives be rotated or replaced?

＋Rotate the reversible inserts at the first sign of glue-line fuzzing; each edge has several usable sections, so a fresh edge takes seconds on the machine.
