How hard is the cutting material?

The carbide grade used in this through hole drills delivers 1,500–2,000 HV / 7,000–9,000 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 through hole drills 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.

Through Hole Drills

Through-hole drills, D 3–16 mm, L 57/70 mm, left and right rotation. Carbide drills for beam drilling and line boring.

The VPOINT Through Hole Drills are a carbide through-hole drilling tool. Ideal for through-hole drilling on beam drilling machines, line boring stations and panel furniture drilling lines.

Product Description

Design and Construction

The through-hole drill series carries tungsten carbide tips for drilling stations on woodworking lines. Drill diameters (ØD) run 3–16 mm in both standard lengths (57 and 70 mm), offered left- and right-hand rotation (L+R) per the specifications table.

How It Works

Through-hole drills pierce the panel completely in beam drilling and line boring stations: the tip geometry centres quickly and breaks the exit side cleanly, leaving a clean hole through the panel. Left- and right-hand versions pair on multi-spindle heads without changing feed logic.

Applications

Through-hole drilling on beam drilling machines
Line boring stations
Panel furniture drilling lines
Multi-spindle drilling heads

Suitable Materials

Melamine-faced particleboard
MDF and laminated boards
Plywood
Solid wood panels

The carbide tips keep hole diameter and exit quality across high-volume drilling.

Material Comparison: Tungsten Carbide vs. PCD

The figures below are typical industry data for CNC tooling. Tungsten carbide is the economic standard for general CNC routing — tough, regrindable and available in every geometry. PCD wins on very high-volume abrasive work; this page covers the carbide line, and the comparison shows where each material wins so you can match the tool to the job.

Property	Tungsten Carbide (This Tool)	PCD Diamond
Hardness	1,500–2,000 HV	7,000–9,000 HV
Tool life on MDF / particleboard / melamine	30–60 h (baseline)	15–20× longer (500–1,200 h)
Tool life on solid hardwood	80–150 h (baseline)	10–13× longer (800–2,000 h)
Edge renewal	4–6 regrinds at shorter intervals	5–8 regrinds, each removing only 0.2–0.3 mm of diamond
Surface finish	Ra ~0.8 μm typical, degrades as the edge wears	Ra ≤ 0.2 μm achievable, stable over the tool life
Thermal conductivity	~80 W/m·K	540–560 W/m·K — heat leaves the edge fast
Friction coefficient	≈ 0.3	≈ 0.05 — lower cutting forces
Fracture toughness	Higher — tolerates interrupted cuts and impacts better	Lower — needs stable, vibration-free setups
Suited for	General-purpose CNC routing in wood, panels, acrylic; the economic standard	Very high-volume abrasive panel work; non-ferrous metals

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

Delivery Scope

Single drill. Order by part number with the diameter, length and rotation direction stated in the specifications table below.

Why Choose VPOINT

One-year warranty on every cutter — defects in material or workmanship are covered for 12 months from delivery.
Custom tooling — diameters, shanks, cutting lengths and flute configurations built to your drawing or sample.
Non-standard fabrication — sizes outside the standard catalogue, including special geometries.
Resharpening service — cutters return to service after regrinding at a fraction of new-tool cost.
Factory-direct since 2008 — ISO 9001 manufacturing in Sichuan and Dongguan, China; no trading intermediaries.

Send a drawing, a sample or a worn tool, and our engineering team will quote the exact specification you need.

Precision & Quality Control

Every cutter is inspected before shipment. Shank diameter, cutting-edge diameter, cutting length and overall length are measured against the values listed in the specifications table, and cutting edge runout is verified on the assembled tool.

Tools measuring outside tolerance do not ship. Inspection is performed under our ISO 9001 quality system, with batch records retained for traceability.

Frequently Asked Questions

Which diameters are available?

＋The VP004101 series covers cutting diameters from 3 mm upward (3, 4, 5, 6, 7 mm and beyond) in 57/70 mm overall lengths, offered as L+R pairs for mirrored spindle positions.

Which machines suit these drills?

＋Beam drilling machines, line boring stations, panel furniture drilling lines and multi-spindle drilling heads are all listed as suitable.

Which rotation should I order?

＋L+R pairs are available. Match each bit to its spindle rotation — right-hand spindles take R bits, left-hand spindles take L bits — so mirrored holes drill in the same cycle.
