Product Description
Carbide Boring Drill bit
Carbide boring bits are cutting tools used for boring holes in hard materials such as metal, wood, plastics, and composites. These bits are made from carbide, a very hard and durable material that is able to withstand high temperatures and abrasion.
Carbide boring bits come in a variety of shapes and sizes, including straight, spiral, and gun drills. They can be used on a wide range of materials and are commonly used in the manufacturing and metalworking industries.
When using carbide boring bits, it’s important to choose the right bit for the job and to use the proper cutting techniques. The cutting speed and feed rate must be carefully controlled to avoid damaging the bit or the workpiece.
Overall, carbide boring bits are a highly effective tool for boring holes in hard materials, and can help to increase productivity and reduce manufacturing costs.
Application
1. Suitable for drilling hole wood, PVC and plastic.
2.Automatic boring machine.
3.Adjustable drill bit for cnc machine center
4.For chip free drilling of through holes in solid wood and wood-based panels.
5.Drill Wood material for chipboard, plywood, hardwood and MDF.

Design and Construction
The solid carbide hinge boring bits carry integral carbide drills for hinge-boring stations. Diameters (ØD) run 3 to 15 mm with 10 mm shanks and total lengths of 57 or 70 mm, offered left- and right-hand rotation (L/R) per the specifications table.
How It Works
The carbide tip sizes the hinge bore accurately while the flutes clear the chip without scoring the hole wall. Left- and right-hand versions pair on multi-spindle boring heads, drilling the hinge cup and screw holes in one pass sequence.
Applications
- Hinge boring on cabinet lines
- Multi-spindle boring heads
- Hardware hole drilling
- High-volume cabinet production
Suitable Materials
- Melamine-faced particleboard
- MDF and laminated boards
- Plywood
- Solid wood panels
Integral carbide holds hole diameter and wall finish across high-volume hinge boring.
Material Comparison: Tungsten Carbide vs. High-Speed Steel
This drill carries tungsten carbide — the production standard for woodworking lines. The figures below are typical industry data showing where carbide and HSS each win, so you can match the material to the job.
| Property | Tungsten Carbide (This Drill) | High-Speed Steel (HSS) |
|---|---|---|
| Hardness | 1,500–2,000 HV | ~850 HV (65 HRC) |
| Hot hardness | Keeps hardness at ~900–1,000 °C | Softens above ~600 °C |
| Edge life in abrasive board | Long baseline life in MDF/particleboard | Shorter — dulled quickly by adhesives and mineral fillers |
| Hole quality over life | Hole diameter holds as the edge wears slowly | Diameter shrinks visibly as the point wears |
| Regrind | 4–6 regrinds typical | 2–3 regrinds, softer edge deforms faster |
| Brittleness | Higher — avoid side loads and impacts | Lower — more forgiving of misuse |
| Suited for | Production drilling in MDF, particleboard, plywood, solid wood | Light-duty and occasional drilling |
Figures are typical published values; actual tool life depends on the workpiece material, feed rate, spindle speed and cooling.
Delivery Scope
Single bit, box quantities on request. Order by the diameter, shank, length and rotation 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.
