Tungsten Carbide burr blank
Core Advantages
-
Ultra-High Hardness: Hardness of HRA 90+, capable of easily handling hard materials like stainless steel, titanium alloys, and cast iron.
-
Wear Resistance: Lifespan is more than 10 times that of high-speed steel tools, reducing frequent replacement costs.
-
High-Temperature Resistance: Stable operation at temperatures up to 1000°C, avoiding softening and deformation.
-
High-Precision Machining: Smooth surface finish supports subsequent precision grinding into complex blade shapes.
Common Models and Sizes
Tungsten Carbide Burr Blanks can be divided into various models based on blade type and application. Standard size ranges are as follows:
| Model | Diameter (mm) | Blade Length (mm) | Total Length (mm) | Application Scenarios |
|---|---|---|---|---|
| Single-Cut Straight | 3-25 | 10-50 | 50-150 | Surface milling, deburring |
| Double-Cut Cross | 4-20 | 15-40 | 60-120 | Fast chamfering, deep groove machining |
| Ball Nose Multi-Cut | 2-12 | 5-30 | 40-100 | Complex surface engraving, mold finishing |
| Tapered Spiral | 5-30 | 20-60 | 70-200 | Hole expansion, bevel machining, weld seam processing |
Customization Supported: Non-standard sizes and special blade types (e.g., serrated, flame-shaped) can be customized based on requirements.

Frequently Asked Questions (FAQ)
Q1: How to choose the right burr blank model?
A1: Select based on material hardness, cutting depth, and target blade shape:
-
Soft Metals (Aluminum, Copper): Recommend single-cut or double-cut types for higher efficiency.
-
Hard Alloys/Quenched Steel: Choose multi-cut ball nose types to reduce cutting resistance.
Q2: Do you support small trial orders?
A2: Yes, we accept trial orders with a minimum of 10 pieces and provide free samples for testing.
Q3: What equipment is needed for subsequent processing of blanks?
A3: A 5-axis tool grinder or dedicated CNC grinding equipment is required for blade shaping.
