Design and Construction
The 1/4″ shank 8-piece double-cut solid carbide rotary burr set covers the standard burr shapes for die grinders and flexible shaft machines. All eight burrs are solid carbide with double-cut fluting (cross-cut teeth) on 1/4″ (6.35 mm) shanks, as listed in the specifications table.
How It Works
Double cut fluting puts two sets of teeth on each flute: cutting is faster with a finer finish and lower pull than single cut, and chips break small. The eight shapes cover deburring, chamfering, contour shaping and material removal on wood, plastics and non-ferrous metals.
Applications
- Deburring and chamfering
- Contour shaping on die grinders
- Weld and seam cleanup on non-ferrous work
- Wood and plastic sculpting
Suitable Materials
- Hardwood and softwood
- Plastics and composites
- Aluminum, copper, brass
- Soft steel (light passes)
Double-cut solid carbide burrs remove material fast with a finer, more controlled finish.
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

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.
