How hard is the cutting material?

The carbide grade used in this diamond v-shaped 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 v-shaped 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 V-shaped knife

The company uses high-end production and testing equipment from Germany, selects international high-quality raw materials, and provides customers with professional supporting production tools and related accessories. The products include saw blades, forming knives, handle milling cutters, drill bits, and various diamond tools.

The VPOINT Diamond V-shaped knife is a replaceable-knife cutting tool for CNC machining centres. Built for CNC machining centres in daily production.

Product Description

The VP0027 diamond V-bit cuts V-grooves in 60° and 90° included angles, with cutting diameters from 12.7 to 50 mm on a 12.7 mm shank and tip lengths matched to the angle, as listed in the specifications table.

Design and Construction

The VP0027 diamond V-bit pairs a solid PCD cutting edge with a 40Cr chrome-molybdenum steel body. One- and two-flute versions cover 60° and 90° included angles from 14 to 50 mm diameter.

How It Works

The V geometry cuts a crisp groove with the angle built into the tool, and the PCD edge holds the tip and the angle in abrasive faced board, keeping groove width consistent.

Applications

Edge rounding and V-grooving on CNC routers
Decorative profiles in panels
Cabinetry and furniture machining
Sign making

Suitable Materials

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

The PCD edge holds the profile through long runs in abrasive sheet goods.

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 low-volume general work — but on abrasive sheet goods the difference in blade life is decisive.

Property	PCD Diamond (This Blade)	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 abrasive boards (fibre cement / composites)	10–15× longer	baseline
Edge renewal	Limited regrinds — the economics come from 15–20× longer intervals between changes, not regrind count	4–6 regrinds at shorter intervals
Cut finish	Ra ≤ 0.2 μm achievable, stable over the blade life	Ra ~0.8 μm typical, degrades as teeth wear
Thermal conductivity	540–560 W/m·K — heat leaves the tooth tip fast	~80 W/m·K
Friction coefficient	≈ 0.05 — lower cutting forces and heat	≈ 0.3
Suited for	Abrasive engineered wood, laminates, composites, fibre cement, non-ferrous metals	General-purpose solid-wood work; the economic choice at lower volumes

Figures are typical published values; actual blade life depends on the workpiece material, feed rate, depth of cut, machine condition and maintenance schedule.

Delivery Scope

Single blade. Order by part number with the diameter, bore, width and tooth count stated in the specifications table below.

Why Choose VPOINT

One-year warranty on every blade — defects in material or workmanship are covered for 12 months from delivery.
Custom tooling — diameters, kerfs, bores and tooth counts built to your drawing or sample.
Non-standard fabrication — sizes outside the standard catalogue, including bore re-sizing and tooth-count changes.
Resharpening service — blades return to service after regrinding at a fraction of new-blade 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 blade, and our engineering team will quote the exact specification you need.

Precision & Quality Control

Every blade is inspected before shipment. Outside diameter, kerf thickness, plate thickness, bore diameter and tooth count are measured against the values listed in the specifications table, and tooth geometry (hook angle, bevel angle) is verified against the design drawing. Blades are stress-checked for runout and tension before packing.

Blades measuring outside tolerance do not ship. Inspection is performed under our ISO 9001 quality system, with batch records retained for traceability.
