How hard is the cutting material?

The carbide grade used in this pcd finger grip 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 finger grip 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 Finger Grip Bits

This PCD finger grip bit machines integrated finger-grip handles directly into furniture fronts — drawer fronts and doors that open without attached handles. One pass forms the grip recess with a comfortable finger radius.

Product Description

PCD Finger Grip Bits for CNC Woodworking

Design and Construction

＋Polycrystalline diamond (PCD) cutting edges are brazed onto a steel body with a finger-grip profile combining a radius and straight relief. The chart lists part numbers LH1503W1504–4402 with cutting diameters from 15.9 to 44.45 mm in 1/4″ and 1/2″ shanks. The series is produced in the Sichuan and Dongguan, China manufacturing bases.

How It Works

＋Mounted in the CNC router, the bit traces the grip channel along the furniture front; the profile mills the recess and the finger-pull radius simultaneously. The PCD edge keeps the grip geometry identical across a full furniture batch on abrasive boards.

Applications

Integrated finger-grip handles in furniture fronts (drawers and doors)
Handleless cabinet and furniture production 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 furniture-front thickness, grip depth and desired handle profile, plus the 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
Dual manufacturing bases in Sichuan and Dongguan, China

Precision & Quality Control

＋Every finger grip bit is inspected before shipment: cutting diameter, radius, shank diameter 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.
