How hard is the cutting material?

The carbide grade used in this diamond trimming knife 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 diamond trimming knife 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.

Diamond trimming knife

PCD trimming bits (Z2), D 6-13 mm, shank 6.35 or 12.7 mm, cutting height 20-30 mm. Straight-flute geometry trims edge banding and laminate overhang flush with the panel face.

The VPOINT Diamond trimming knife is a replaceable-knife cutting tool. Ideal for edge banding trimming on furniture panels, laminate and veneer overhang flush-trimming and flush trimming on cabinet doors and drawer fronts.

Product Description

The VP0026 series trimming bit pairs a solid PCD cutting edge with a 40Cr chrome-molybdenum steel body in a two-flute straight geometry that cuts a flat, flush surface. Diameter and cutting length follow the specifications table.

Design and Construction

The VP0026 series trimming bit pairs a solid PCD cutting edge with a 40Cr chrome-molybdenum steel body. The two-flute (Z2) straight geometry cuts a flat, flush surface with the panel face. Cutting diameters (ØD) run 6 to 13 mm with shanks (Ød) of 6.35 or 12.7 mm; cutting height (H) spans 20 to 30 mm, covering standard panel and banding thicknesses.

How It Works

The bit trims overhanging edge banding, laminate or veneer flush with the panel surface. The straight flutes shear the overhang in one pass while the flat PCD edge lands on the panel face, leaving no step or ridge. Shank options of 6.35 mm and 12.7 mm fit both portable trim routers and fixed CNC spindles.

Applications

Edge banding trimming on furniture panels
Laminate and veneer overhang flush-trimming
Flush trimming on cabinet doors and drawer fronts
Post-forming edge cleanup

Suitable Materials

Melamine-faced particleboard and MDF
Laminate (HPL) and edge banding strips
Veneered plywood
Solid wood

The PCD edge trims resin-rich banding and laminated faces without build-up, keeping the cut flush 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, shank and cutting height 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 — geometries, diameters, cutting lengths and shank configurations built to your drawing or sample.
Non-standard fabrication — profiles and sizes outside the standard catalogue, including profile restoration and special applications.
Resharpening service — cutters return to service after regrinding, restoring near-original edge performance 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 edge condition, cutting diameter (ØD), shank diameter (Ød), cutting length (L1) and overall length (L) 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.
