Factory Wholesaler Cutting Burrs Set for Die Grinder Drill Bits
Multi-shape double-cut carbide burr set for die grinders: cylinder, ball, tree and flame heads in one wholesale case.
Design and Construction
A wholesale multi-shape set: double-cut tungsten carbide heads in cylinder, cylinder ball-nose, ball, tree, pointed-tree and flame geometries, each seated in a colour-coded plastic holder. Heads are ground from integral YG-series carbide with crossed flutes for fast, low-vibration stock removal.
How It Works
Double-cut crossed flutes shear metal into small chips at 6,000-50,000 RPM, so the burr pulls itself into the work with modest hand pressure. Switching head shapes covers flat, contoured and internal work without changing setups.
Applications
Die-grinder maintenance work, weld dressing, machine-shop deburring, fabrication shops and tool-room rework.
Field Cases
- Fabrication shop: removes MIG weld crowns on 6 mm mild-steel brackets with the flame head, then blends the toe with the tree head – about 20 seconds per joint.
- Maintenance team: dresses a worn cast-iron pump housing bore with the cylinder ball-nose head before re-sleeving.
- Tool room: re-cuts hardened clamp jaws (45 HRC) with the cylinder head where milling would need annealing.
Performance Data
| Metric | Value / Observation |
|---|---|
| Speed range | 6,000-50,000 RPM (lower for larger diameters) |
| Removal rate | Up to about 8 cm³/min in mild steel with a 12 mm head at 25,000 RPM (typical bench data) |
| Edge life | 5-10x an HSS burr of the same size on steel above 35 HRC |
| Head hardness | 1,300-1,500 HV (YG-series carbide) |
Suitable Materials
Steel, cast iron, stainless steel, copper alloys and hardwood.
Material Comparison: Set Purchase vs Single-Purchase Economics
What a multi-shape set changes in the cost line – typical industry data:
| Factor | Wholesale Set (this set) | Buying Singles |
|---|---|---|
| Coverage | Six contour families in one case | One geometry per purchase |
| Downtime | No job stop for a missing shape | Job waits on a tool order |
| Cost per shape | Set pricing – lowest per head | Single-unit pricing |
| Consumption planning | Reorder one shape when it wears | Whole-range reorder each time |
| Training | One case teaches the shape families | Fragmented references |
Delivery Scope
Full set in a plastic storage case; single shapes available separately. Laser marking and custom case printing on wholesale orders.
Why Choose VPOINT
One case covers the common contour families, backed by VPOINT regrinding service and one-year warranty.
Precision & Quality Control
Each head is inspected for flute symmetry, edge sharpness and shank runout at micrometre level; batches are traceable under ISO 9001.

Frequently Asked Questions
Are all heads double cut?
Yes, every head in this set is double cut for fast stock removal; single-cut and aluminum-cut versions can be mixed into the set on request.
Will these burrs fit my die grinder?
The 6 mm (1/4″) shanks fit standard air die grinders, cordless rotary tools and drill-press collets.
Can I use them on stainless steel?
Yes. Double-cut flutes resist chip loading on stainless; keep the speed in the mid range and let the burr cut.
What is the advantage over single burrs?
One set covers flat, curved and internal contours, so total tooling cost per project drops and work stops less often for tool changes.
Do you support wholesale branding?
Yes – laser marking, custom holders and printed cases are available for wholesale orders.
