Unlock precision and durability with our Carbide Blind Drill Bits for Wood. Designed for woodworking enthusiasts and professionals alike, these bits combine the toughness of carbide with the finesse needed for clean, accurate drilling in wood. Perfect for applications where a blind hole is required, these bits deliver exceptional performance and longevity.
- Material: Made from carbide, these drill bits offer high hardness, wear resistance, and heat resistance, making them suitable for drilling tough materials like hardwood, metal, and composites.
- Precision: Designed for accuracy, ensuring that the depth and diameter of the hole are consistent.
- Durability: Carbide tips maintain sharpness longer than other materials, providing longer tool life.
- Flute Design: The flute design helps in chip removal, reducing heat build-up and improving drilling efficiency.
- Variety of Sizes: Available in various diameters and lengths to accommodate different hole sizes and depths.
Size:
| Rotation | Diameter(D) | TotalLength(L) |
| R/ L | 2.0mm | 57/70mm |
| R/ L | 2.5mm | 57/70mm |
| R/ L | 3.0mm | 57/70mm |
| R/ L | 4.0mm | 57/70mm |
| R/ L | 5.0mm | 57/70mm |
| R/ L | 6.0mm | 57/70mm |
These bits are ideal for use in CNC machines, drill presses, and other precision drilling setups, especially when working with materials like metal, wood, and composites where a clean, accurate blind hole is required.
Design and Construction
The CNC carbide blind drill bits for wood carry carbide tips for blind (non-through) holes. The specifications table lists the product attributes as stated by the factory, including type (center drill bit, core drill bit), finish and intended application (wood).
How It Works
A blind hole stops at controlled depth: the depth stop or program sets the depth and the carbide tip cuts a flat or centred bottom without piercing the panel. Used where hardware screws or dowels seat in blind positions.
Applications
- Blind-hole drilling on CNC centres
- Hardware seat drilling
- Depth-controlled drilling
- Cabinet and panel production
Suitable Materials
- Melamine-faced particleboard
- MDF and laminated boards
- Plywood
- Solid wood panels
Carbide tips hold blind-hole depth and diameter across programmed runs.
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 and length 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.
