Premium Tungsten Carbide Rotary Burr Blanks | Un-fluted Preforms & Shaded Blanks for Manufacturer
$19.87
Manufactured from 100% virgin sub-micron tungsten carbide powder, our blanks feature exceptional internal structural homogeneity, optimized grinding allowances, and superior metallurgical properties for seamless shank brazing. Whether you are producing standard USCTI shapes or custom high-performance geometries, our blanks ensure minimal wheel wear during your fluting process and maximum tool life for the end-user.
1. Technical Specifications & Geometry Matrix
We manufacture a complete line of un-fluted blanks adhering to USCTI (United States Cutting Tool Institute) and DIN dimensional standards:
2. Mechanical Properties & Material Grades
To balance the high-impact stress of manual deburring with edge sharpness, we utilize optimized B2B industrial grades:
Grade Recommendation (K20-K30 Matrix):
Density: 14.65 g/cm ^3 to 14.95 g/cm ^3 (Ensures uniform weight distribution and balanced rotational physics).
Hardness: HRA 90.5 to HRA 91.5 (Delivers long-lasting sharpness for final flutes).
TRS (Transverse Rupture Strength): ≥ 2800 MPa (Prevents head snapping at the brazing joint during heavy stock removal).
3. Manufacturing Technology & Technical Solutions
Q: Why do global rotary burr factories prefer Panda Carbide blanks?
We solve the three major bottlenecks in burr grinding:
Optimized Grinding Allowance: Our specialized extrusion and pressing dies provide a precise, minimized grinding allowance. This significantly reduces your CNC diamond wheel wear and shortens your cycle times per burr.
Flawless Brazing Surface Integration: For composite burrs (carbide head brazed to steel shanks), our blanks undergo a proprietary surface preparation process. This ensures maximum wettability for silver braze alloys, preventing catastrophic head separation under high thermal loads.
Advanced HIP Sintering: All blanks are processed via Overpressure Hot Isostatic Pressing (HIP), eliminating internal micro-voids and trace structural defects that cause tool failure during fluting or end-use.
4. Processing & Material Recommendations for Finished Burrs
Once fluted by your facility, the finished rotary burrs are highly recommended for high-efficiency deburring, chamfering, and weld preparation on the following target substrates:
Hardened Steel & Stainless Steel (Inox)
Cast Iron & Titanium Alloys
Aluminum, Brass, and Plastics (Alu-Cut configurations)
5. B2B Sourcing & OEM Support
Flexible Supply Configurations: Available as solid carbide blanks or pre-brazed assemblies (carbide head joined to steel/stainless shanks according to custom lengths).
Bespoke Preforms: We create non-standard, custom-molded stepped preforms based on your unique technical drawings to maximize your manufacturing efficiency.
