Double Cut Carbide Rotary Burr Set-10 Pcs 1/4″ Shank
10 pcs double-cut carbide rotary burr set, 1/4″ shanks. Full shape coverage for die grinder work.
A Double Cut Carbide Rotary Burr Set typically features burrs with a unique cross-cut design, providing enhanced material removal and smoother finishes compared to single-cut burrs. These burrs are widely used for cutting, shaping, grinding, and deburring various materials such as metals (like steel and aluminum), plastics, and even wood.
A Double Cut Carbide Rotary Burr Set typically features burrs with a unique cross-cut design, providing enhanced material removal and smoother finishes compared to single-cut burrs. These burrs are widely used for cutting, shaping, grinding, and deburring various materials such as metals (like steel and aluminum), plastics, and even wood.
A Double Cut Carbide Rotary Burr Set is a highly versatile toolset designed for precision shaping, deburring, and material removal. These burrs are primarily used in metalworking but are also effective on other materials such as plastics, ceramics, and even wood. The double cut design provides a smoother finish and reduces chip clogging.
- Double Cut Design: The crossed cutting edges produce smaller chips, allowing for a smoother finish and better control compared to single-cut burrs.
- Material: Made from tungsten carbide, offering excellent hardness, durability, and heat resistance, making them ideal for high-speed machining.
- Shank Size: Commonly 1/4″ shanks, fitting most die grinders or rotary tools.
- Variety of Burr Shapes: Burr sets typically include a range of shapes such as:
- Cylindrical: For flat surface and contour work.
- Ball: For precision grinding and concave cutting.
- Oval: For rounding and contouring.
- Tree: For working in tight angles and corners.
- Cone: For chamfering and deburring.
Applications:
- Metalworking: Grinding, polishing, and removing material from metal surfaces.
- Woodworking: Shaping and carving wood, though not as common as metal use.
- Plastics and Ceramics: Cutting and shaping non-metal materials.
- Automotive: Porting and polishing engine parts, removing welds.
- Fabrication: General smoothing and deburring of metal edges and surfaces.
Design and Construction
The double-cut carbide rotary burr set (10 pieces, 1/4″ shank) covers the standard burr shapes for die grinders and flexible shaft machines. All ten burrs are solid carbide with double-cut fluting on 1/4″ (6.35 mm) shanks, as listed in the specifications table.
How It Works
Double cut fluting cuts fast with a finer finish and lower pull than single cut; chips break small and clear from the flutes. The ten shapes cover the full range of deburring, shaping, contouring and cleanup tasks 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)
Ten double-cut solid carbide shapes cover the full range of grinding and shaping tasks.
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
10-piece set. Shape list per the specifications table below; individual shapes available on request.
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.
