Long Drill Bits For Wood Deep Hole
Long carbide drill bits for deep holes in wood. Made to order for your depth, diameter and shank.
Here are the key features of carbide long drill bits for wood deep hole drilling:
Product Description
Here are the key features of carbide long drill bits for wood deep hole drilling:
-
Exceptional Durability: Made from tungsten carbide, these bits resist wear and maintain sharpness longer than traditional steel bits, ensuring longevity.
-
Precision Drilling: The hardness of carbide allows for clean, accurate cuts, minimizing splintering and providing smooth holes in various wood types.
-
Extended Length: Designed specifically for deep hole drilling, these bits offer the length needed to reach greater depths without compromising stability.
-
Versatile Application: Suitable for a range of wood materials, from softwoods to hardwoods, making them ideal for diverse woodworking projects.
Application
-
Furniture Making: Ideal for drilling deep holes in furniture components, such as legs, spindles, and dowels, ensuring precise and stable joints.
-
Cabinetry: Used in the construction of cabinets and shelving, these bits provide the depth and accuracy needed for hidden screws or joinery techniques.
-
Woodturning: Essential for woodturning projects where deep, precise holes are required, such as creating hollow vessels or lamp bases.
Design and Construction
The long drill bits for wood deep-hole drilling carry carbide cutting geometry in extended overall lengths. Bits are produced to order: state the drilling depth, hole diameter and shank when ordering, and the bit is built to match the machine and job.
How It Works
Deep holes need chips evacuated over a long flute path: the long-bit geometry keeps the flutes clear while the carbide edge holds diameter through the full depth. Used for deep dowel holes, anchor holes and through-tenon holes in thick stock.
Applications
- Deep-hole drilling in thick panels and timber
- Deep dowel holes
- Anchor and bolt holes
- Structural timber joinery
Suitable Materials
- Solid wood
- Glulam and engineered timber
- Thick panels
- MDF and particleboard
The carbide edge holds hole diameter over the full depth of deep holes.
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
Bits are made to order. Send the drilling depth, hole diameter and shank, or the old bit as a sample, and our engineering team will quote the exact specification.
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.
