How hard is the cutting material?

The carbide grade used in this pcd compression router bit delivers 1,500–2,000 HV / 7,000–9,000 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 compression router bit 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.

PCD Compression Router Bit

PCD compression router bits size and groove solid wood and wood-based panels on compatible CNC woodworking machines. The series covers four tooth layouts — (1+1)Z, (2+2)Z, (3+3)Z and (4+4)Z — with cutting diameters from 6 to 60 mm, cutting heights from 15 to 60 mm and shanks from 8 to 32 mm.

Product Description

PCD Compression Router Bit for CNC Woodworking

Design and Construction

＋The cutting edges are polycrystalline diamond (PCD) brazed onto a 40Cr chrome-molybdenum steel body in a compression geometry: the tooth layout runs (1+1)Z to (4+4)Z, pairing an up-shear flute with a down-shear flute at each level. Shank diameters follow the table — 8, 12/12.70, 12.7, 16/20/25 and 20/25/32 mm options. The series is produced in the Sichuan and Dongguan, China manufacturing bases.

How It Works

＋In a single pass the lower flutes shear upward and the upper flutes shear downward, directing chip pressure toward the panel core. Both faces of the panel are pressed inward, so veneers and coatings exit clean on the top and bottom of the cut at the same time — the reason compression geometry is preferred for sizing and grooving double-sided panels. Select the tooth layout, cutting height and shank option as one configuration; the listed combinations are not interchangeable.

Applications

Sizing and grooving solid wood and wood-based panels
For compatible CNC woodworking machines, engraving machines and routing machines

Suitable Materials

Veneered or uncoated chipboard, plywood, MDF and suitable solid-wood workpieces
Suitability depends on the specific material grade, profile and machining conditions; confirm the application before ordering

Material Comparison: Traditional Brazed Tungsten Carbide vs. Diamond (PCD) Router Bit

＋Typical industry data for reference. Actual results depend on the workpiece grade, machine condition and feed rate.

Property	Traditional Brazed Tungsten Carbide Router Bit	Diamond (PCD) Router Bit
Cutting material hardness	1,500–2,000 HV	7,000–9,000 HV
Edge life on MDF / particleboard	Baseline (1×)	15–20× longer edge life
Edge life on solid wood	Baseline (1×)	10–13× longer edge life
Edge life on acrylic	Baseline (1×)	10–15× longer edge life
Regrinding / refurbishing cycles	2–4 times	5–8 times
Cut edge quality	Ra 0.4–0.8 µm, more fuzzing	Ra 0.2–0.4 µm, cleaner edge
Thermal conductivity	≈ 100 W/m·K	≈ 500 W/m·K, heat cleared faster
Friction coefficient	≈ 0.3	≈ 0.05–0.1, lower cutting force
Chipping risk on brittle panels	Higher at high feed	Lower, stable edge at high feed
Cost per metre of cutting	Higher over long runs	Lower over long runs

Delivery Scope

Each tool is packed in an individual plastic box.

＋Each order also includes an inspection record. Custom configurations are produced after the workpiece material, machine model and required dimensions are confirmed.

Why Choose VPOINT

＋VPOINT supports this series with:

One-year warranty on every router bit
Custom and non-standard diameters, cutting heights and shanks produced to order
Regrinding service to extend tool life
Factory direct since 2008, ISO 9001 certified
Dual manufacturing bases in Sichuan and Dongguan, China

Precision & Quality Control

＋Every compression router bit is inspected before shipment: cutting diameter, shank diameter, cutting height and tool runout are checked against the specification table at micron level. Production follows an ISO 9001 process with batch traceability, so reorders match the original configuration.

Specifications

The table below lists selected configurations transcribed from the original four specification charts. All dimensions are in millimetres. D is cutting diameter, H cutting height, d shank diameter, L overall length and Z tooth layout. Each row is a separate configuration; confirm the exact shank option and configuration before ordering — combinations and tooth layouts must not be interchanged.

Frequently Asked Questions

Which tooth layouts are available?

＋Four layouts: (1+1)Z, (2+2)Z, (3+3)Z and (4+4)Z, with cutting diameters from 6 to 60 mm and cutting heights from 15 to 60 mm. Each table row is one configuration and the combinations must not be interchanged.

How do I choose the right compression configuration?

＋Match the cutting height to the panel thickness and pick the tooth layout for the finish required, then select the shank for your collet as one complete table row. Confirm the panel thickness and operation before choosing a compression layout.

Can you supply the full LH055 model series?

＋Yes. Model codes LH05501 through LH05524 are listed on the original chart alongside the four series above. Send the item code or required dimensions for confirmation and quotation.

What should I send for a custom request?

＋The item code or required profile drawing, tool dimensions, workpiece material, machine model, cutting direction and quantity, plus a reference photo or current-tool drawing where available.
