How hard is the cutting material?

The carbide grade used in this pcd diamond spiral router bits z3+3 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 pcd diamond spiral router bits z3+3 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.

Cost Performance

The Z3+3 layout pairs a roughing and a finishing diamond in one cutter, so sizing and pre-cutting run in a single pass. The geometry is designed for coated timber and composite workpieces machined at high feed speed, and the 25 mm shank with seven reference sizes from D18 to D25 covers the panel thicknesses commonly seen on nesting and panel lines.

Every cutter is made at our own Sichuan and Dongguan factories under an ISO 9001 system, with 40Cr chrome-molybdenum steel bodies, a one-year warranty and support for non-standard sizes from drawings. The size references above are transcribed from the original product chart; confirm the final drawing and configuration before ordering.

PCD Diamond Spiral Router Bits Z3+3 for CNC Woodworking

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 cutter life is decisive.

Property	PCD Diamond (This Cutter)	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.

Frequently Asked Questions

What is the PCD Diamond Spiral Router Bits Z3+3 used for?

High-performance sizing and pre-cutting: the Z3+3 diamond layout combines rough and finish milling in one pass on CNC panel lines.

Which materials does it suit?

Particle board and MDF panels, raw chipboard and plastic material, plus coated timber and composite workpieces machined at high feed speed.

How do I choose the right size?

Seven reference sizes run from D18 to D25 mm on a 25 mm shank, with cutting lengths (L1) from 22 to 60 mm and overall lengths from 100 to 130 mm — match the cutter diameter and cutting length to the panel stack and machine clearance.

Can I order a custom size?

Yes. Send the required cutter diameter, cutting length and shank, plus the workpiece material and machine model, and the cutter will be produced to order.

Custom tooling and quotation

Send the item code or required profile drawing, tool dimensions, workpiece material, machine model, cutting direction and quantity. A reference photo or current-tool drawing helps us review a custom request. Confirm the final specification and availability before ordering.

Each tool is packed in an individual plastic box.
