How hard is the cutting material?

The carbide grade used in this pcd spiral router bit diamond compression end mill 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 spiral router bit diamond compression end mill 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 Spiral Router Bit Diamond Compression End Mill

PCD spiral router bit diamond compression end mills handle CNC panel nesting, slotting and compatible bottom-clearing operations on industrial CNC machining centres. The compression layout keeps both panel faces clean through the full cutting height, and configurations are produced to order against the required tool drawing.

Product Description

PCD Spiral Router Bit Diamond Compression End Mill for CNC Woodworking

Design and Construction

＋The spiral flutes carry polycrystalline diamond (PCD) cutting edges brazed onto a 40Cr chrome-molybdenum steel body in a compression arrangement. The tools pictured carry shank markings such as 16*25*H38 (2+2)T and 16*22*H58 (2+2)T, indicating 16 mm cutting diameters with (2+2)Z tooth layouts and different cutting lengths. The series is produced in the Sichuan and Dongguan, China manufacturing bases.

How It Works

＋As the tool plunges and traces the nesting path, the lower flutes shear upward and the upper flutes shear downward, pressing chip pressure toward the panel core. Both faces survive a full-depth through cut with clean edges, which suits nested-based manufacturing where every part is cut from a coated panel in one pass. Confirm spindle and collet fit, cutting direction, panel thickness and the required compression layout for the operation.

Applications

CNC panel nesting, slotting and compatible bottom-clearing operations
For compatible industrial CNC machining centres

Suitable Materials

MDF, multilayer plywood, solid-wood panels and blockboard, subject to material review
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

Configurations are produced to order after the tool drawing and quotation are confirmed.

＋Each order includes the selected configuration, protective packaging and an inspection record. Send the required dimensions together with panel thickness and the machining task so the compression layout is confirmed before production.

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 diamond compression end mill 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.

Frequently Asked Questions

Are standard sizes available from stock?

＋No. The original page specifies no numerical size range — each tool is produced to order against the final drawing and quotation. Provide the required cutting diameter, cutting length, shank, overall length and tooth layout.

What do the markings on the pictured tools mean?

＋The pictured tools carry shank markings such as 16*25*H38 (2+2)T and 16*22*H58 (2+2)T — 16 mm cutting diameters with (2+2)Z tooth layouts and different cutting lengths. They are examples of produced configurations, not a stock list.

Which materials suit this end mill?

＋MDF, multilayer plywood, solid-wood panels and blockboard are listed, subject to material review. Confirm the specific grade and the machining task before ordering.

What information is needed for a quotation?

＋The required cutting diameter, cutting length, shank diameter, overall length and tooth layout, together with panel thickness, spindle and collet fit, cutting direction and the machining task.
