How hard is the cutting material?

The carbide grade used in this rough/fine trimming cutters delivers 7,000–9,000 HV / 1,500–2,000 HV hardness, which keeps the cutting edge sharp under continuous load.

Can you supply OEM or ODM parts, and how fast?

Yes. VPOINT TOOLS runs two factories in China (Chengdu and Dongguan) and accepts OEM and ODM orders. Standard samples and in-stock items ship within 24-48 hours; custom tooling is quoted per specification.

Which machines and materials is this rough/fine trimming cutters used for?

It is used on CNC routers, table saws and spindle moulders for cutting particle board, MDF, plywood, solid wood and aluminium composite panels. Chipbreaker or replaceable-insert models are available for high-volume production runs.

Do you ship worldwide?

Yes. VPOINT TOOLS ships carbide and PCD woodworking tooling to more than 100 countries. Tell us the destination and application and we will confirm freight cost and lead time.

Rough/Fine Trimming Cutters

Rough/fine trimming cutters for edge banders, D 56-75 mm, Z 3-6, bores 16/20 mm. PCD edges for trim and corner-radius stations.

The VPOINT Rough/Fine Trimming Cutters are a carbide woodworking cutting tool. Ideal for rough and fine trim stations on edge banders, edge band flush trimming and corner radius forming on edge banders.

Product Description

The rough/fine trimming cutter series covers edge banding trimming units with PCD cutting edges, in -J (rough) and -N (fine) versions across 56, 69, 70 and 75 mm diameters, matched to the station’s bore and bond.

Design and Construction

The rough/fine trimming cutter series covers the trimming units of edge banding machines, with PCD cutting edges. Part numbers (-J and -N series) cover diameters (ØD) of 56, 69, 70 and 75 mm with bores (Ød) of 16 and 20 mm, cutting heights (H) of 13-14 mm and tooth counts of 3 to 6, as listed in the specifications table.

How It Works

Mounted in the trimming units of the edge bander, the cutters trim the banded edge flush and form the corner radii. The roughing station removes band overhang; the fine station finishes the edge surface. PCD edges hold the trim geometry in abrasive banding material (PVC, ABS, melamine band) far longer than carbide.

Applications

Rough and fine trim stations on edge banders
Edge band flush trimming
Corner radius forming on edge banders
Furniture panel edge finishing

Suitable Materials

Edge banding strips (PVC, ABS, melamine, wood veneer)
Melamine-faced particleboard
MDF and laminated boards
Veneered panels

The PCD edges resist the abrasive fillers in PVC and melamine bands, holding trim quality across long production runs.

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.

Delivery Scope

Single cutter. Order by part number with the diameter, bore, height and tooth count 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, 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.
