How hard is the cutting material?

The carbide grade used in this pcd core box bits delivers 1,500–2,000 HV (carbide) / 7,000–9,000 HV (PCD diamond) 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 core box bits 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 Core Box Bits

These PCD core box bits cut round-bottom grooves, veining lines and spherical recesses on CNC woodworking machines, engraving machines and routing machines. The polycrystalline diamond edge keeps the round profile crisp through long runs on abrasive panels.

Product Description

PCD Core Box Bits for CNC Woodworking

Design and Construction

＋Polycrystalline diamond (PCD) cutting edges are brazed onto a precision-ground steel body with a polished 12.7 mm shank. The chart lists item codes LH10001–LH10014 with cutting diameters from 4.76 to 50 mm, cutting heights from 6 to 30 mm and radii from 2.38 to 25 mm, all in 2Z tooth layout. The series is produced in the Sichuan and Dongguan, China manufacturing bases.

How It Works

＋Mounted in the CNC spindle, the half-round diamond profile shears a smooth round-bottom channel in a single pass. The PCD edge holds its radius on MDF and particleboard, so veining lines and recesses stay consistent across the whole nesting sheet.

Applications

Round-bottom grooves, veining and spherical recesses
Decorative carving and panel detailing on CNC routers

Suitable Materials

Hardwood, softwood, plywood and composite workpieces, subject to grade and application review
Suitability depends on the specific material grade, profile and machining conditions; confirm the application before ordering

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

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

Property	Traditional Carbide Router Bit	Diamond (PCD) Router Bit
Cutting edge hardness	1,500–2,000 HV (carbide)	7,000–9,000 HV (PCD diamond)
Edge life on abrasive panels	Baseline (1×)	15–20× longer edge life
Heat resistance of the edge	Loses hardness above ≈ 315 °C	Retains hardness up to ≈ 1,000 °C
Feed rate at equal quality	Lower	Higher
Sharpness retention on MDF / particleboard	Dulls quickly	Holds the edge through long runs
Regrinding cycles over tool life	2–4 times	5–8 times
Cut edge quality as the edge wears	More fuzzing and tearout	Consistent clean walls
Chipping risk on brittle boards	Higher at high feed	Lower, stable edge at high feed
Typical machines	Light-duty routers	CNC routers, engraving and routing machines
Cost per metre of cut	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. Send the item code or required profile drawing, tool dimensions, workpiece material, machine model, cutting direction and quantity so the configuration is confirmed before production.

Why Choose VPOINT

＋VPOINT supports this PCD router bit series with:

One-year warranty on every tool
Custom profiles, diameters and shanks produced to order
Regrinding service to extend tool life
Factory direct since 2008, ISO 9001 certified

Frequently Asked Questions

Which diameters and radii are available?

＋Item codes LH10001 through LH10014 cover cutting diameters from 4.76 to 50 mm with radii from 2.38 to 25 mm, all 2Z, as shown in the specification chart.

Which machines can run these bits?

＋Compatible CNC woodworking machines, engraving machines and routing machines; confirm the spindle or collet interface (12.7 mm shank) and machine clearance.

Can it cut spherical recesses?

＋Yes. Round-bottom grooves, veining and spherical recesses are the listed operations; share the recess profile so the cutter shape is checked against the workpiece.
