How hard is the cutting material?

The carbide grade used in this carbide hinge boring bit delivers ≈ 60–65 HRC (HSS) / 1,500–2,000 HV (solid carbide) 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 carbide hinge boring 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.

Carbide Hinge Boring Bit

This hinge boring tool combines carbide cutting edges with a steel shank for drilling hinge holes in solid-wood panels, particleboard, plywood and MDF. Diameters from 15 to 25 mm in a 70 mm overall length cover the standard hinge-cup range, and right- or left-hand rotation is selected to match the boring spindle.

Product Description

Carbide Hinge Boring Bit for Woodworking Production

Design and Construction

＋The cutting head is tungsten carbide braised-ground for hinge-cup boring, brazed onto a polished steel shank. The chart lists cutting diameters 15, 16, 17, 18, 19, 20 and 25 mm at a 70 mm overall length, in right- and left-hand versions for multi-spindle boring heads. Production takes place in the Sichuan and Dongguan, China manufacturing bases.

How It Works

＋Mounted in the boring spindle, the carbide lip and spur shear the hinge-cup seat cleanly in one plunge. The carbide edge holds its diameter through thousands of holes on MDF and particleboard, keeping hinge cups at a consistent press fit without rework.

Applications

Hinge-hole boring on six-sided drilling machines, multi-spindle boring machines, bench drilling machines and side-hole drilling machines
Hinge-cup and system-hole drilling in cabinet and furniture panels

Suitable Materials

Solid-wood panels, particleboard, plywood and MDF, subject to grade and application review
Suitability depends on the specific material grade, machine condition and machining parameters; confirm the application before ordering

Material Comparison: High-Speed Steel (HSS) Tool vs. Solid Carbide Tool

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

Property	High-Speed Steel (HSS) Tool	Solid Carbide Tool
Cutting edge hardness	≈ 60–65 HRC (HSS)	1,500–2,000 HV (solid carbide)
Heat resistance of the edge	Loses hardness above ≈ 315 °C	Retains hardness up to ≈ 1,000 °C
Edge life on abrasive panels	Baseline (1×)	5–10× longer edge life
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	Limited	More regrinds
Cut edge quality as the edge wears	More fuzzing and tearout	Consistent clean walls
Rigidity in long tools	Lower	Higher (solid carbide body)
Typical machines	Light-duty routers and drills	CNC machining centres, multi-spindle borers
Cost per hole / metre of cut	Higher over long runs	Lower over long runs

Delivery Scope

Select the required diameter and rotation with your enquiry; each configuration is produced against the confirmed specification.

＋Each order also includes an inspection record. Send the hinge cup diameter, boring depth, board material, machine model and required rotation so the configuration is confirmed before production.

Why Choose VPOINT

＋VPOINT supports this carbide tool series with:

One-year warranty on every tool
Custom diameters, shanks and rotations produced to order
Regrinding service to extend tool life

Frequently Asked Questions

Which diameters are available?

＋The chart lists cutting diameters of 15, 16, 17, 18, 19, 20 and 25 mm, all at a 70 mm overall length.

Which rotation should I choose?

＋Multi-spindle boring heads alternate spindle rotation; match the rotation (right- or left-hand) of the spindle position where the bit will run. Send the machine model so the pairing is confirmed.

Which machines suit this bit?

＋Six-sided drilling machines, multi-spindle boring machines, bench drilling machines and side-hole drilling machines are all listed as suitable.

What should I send for a quotation?

＋Hinge cup diameter, boring depth, board material, machine model, required rotation and quantity, plus a current-tool photo or dimensioned drawing where available.
