How hard is the cutting material?

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

What is the PCD Round Over Bit used for?

It rounds over and eases sharp workpiece edges on CNC woodworking machines.

Which radius range is available?

Radii from 1.59 to 12.7 mm across 19 part numbers, on 12.7 mm and 6.35 mm shanks — choose the finished edge radius and shank size together.

Which materials does it suit?

Wood, MDF, plywood and composite workpieces; confirm the grade and edge section before ordering.

Can I order a custom radius?

Yes. Send the finished edge radius, shank size and a profile drawing, and the cutter will be produced to order.

PCD Round Over Bit

Product Description

PCD Round Over Bit for CNC Woodworking

VPOINT offers PCD Round Over Bit for rounding over and easing sharp workpiece edges. This page brings together the original product information, available size references and the details needed for a tooling enquiry.

Applications and material selection

Typical operation: rounding over and easing sharp workpiece edges.

Materials listed for this product include wood, MDF, plywood and composite workpieces. Suitability depends on the specific material grade, profile and machining conditions; confirm the application before ordering.

Machine compatibility and profile selection

For compatible CNC woodworking machines, engraving machines and routing machines. Confirm the spindle or collet interface, cutting direction, machine clearance and workpiece setup for the selected tool.

Choose the finished edge radius and shank size together. Check the cutting height against the edge section and workpiece thickness before ordering.

Material Comparison: PCD vs. Tungsten Carbide

The figures below are typical industry data for production woodworking. PCD does not replace carbide in every job — carbide remains the right choice for low-volume general work — but on abrasive sheet goods the difference in blade life is decisive.

Property	PCD Diamond (This Blade)	Tungsten Carbide
Hardness	7,000–9,000 HV	1,500–2,000 HV
Tool life on MDF / particleboard / melamine	15–20× longer (500–1,200 h)	30–60 h (baseline)
Tool life on solid hardwood	10–13× longer (800–2,000 h)	80–150 h (baseline)
Tool life on abrasive boards (fibre cement / composites)	10–15× longer	baseline
Edge renewal	Limited regrinds — the economics come from 15–20× longer intervals between changes, not regrind count	4–6 regrinds at shorter intervals
Cut finish	Ra ≤ 0.2 μm achievable, stable over the blade life	Ra ~0.8 μm typical, degrades as teeth wear
Thermal conductivity	540–560 W/m·K — heat leaves the tooth tip fast	~80 W/m·K
Friction coefficient	≈ 0.05 — lower cutting forces and heat	≈ 0.3
Suited for	Abrasive engineered wood, laminates, composites, fibre cement, non-ferrous metals	General-purpose solid-wood work; the economic choice at lower volumes

Figures are typical published values; actual blade life depends on the workpiece material, feed rate, depth of cut, machine condition and maintenance schedule.
