How hard is the cutting material?

The carbide grade used in this pcd horizontal crown bit 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 horizontal crown 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 Horizontal Crown Bit

This PCD horizontal crown bit cuts sweeping cove and concave profiles for crown mouldings and decorative work. The large-diameter diamond profile machines wide moulding curves that smaller bits cannot form in one pass.

Product Description

PCD Horizontal Crown Bit for CNC Woodworking

Design and Construction

＋Polycrystalline diamond (PCD) cutting edges are brazed onto a large steel body with a horizontal crown profile. The chart lists part numbers 1826W2908–9508 with cutting diameters from 28.6 to 95.2 mm and cutting heights from 4 to 10 mm in a 1/2″ shank. The series is produced in the Sichuan and Dongguan, China manufacturing bases.

How It Works

＋In the CNC router the crown profile sweeps the cove across the workpiece face; the wide diamond edge forms the full concave curve in one pass. The PCD edge holds the curve geometry on abrasive boards, keeping the moulding detail consistent.

Applications

Sweeping cove and concave profiles for crown mouldings and decorative work
Wide decorative curves on CNC routers and moulding machines

Suitable Materials

MDF, chipboard and calcium board, 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 full moulding cross-section, required profile depth and workpiece dimensions; the overall cutter diameter and available machine clearance are reviewed together before production.
