Tungsten Carbide Burr Manufacturer for Wholesale and OEM Supply
SINOLITE supplies tungsten carbide burrs for deburring, weld removal, edge preparation, shaping, grinding and surface finishing. They are suitable for die grinders, pneumatic tools and compatible rotary equipment used in metal fabrication, mould making, foundries, automotive repair and industrial maintenance.
Our carbide rotary burrs use a 100% virgin tungsten carbide cutting head and a durable 40Cr steel shank. Hardened and honed cutting edges provide consistent material removal, while the silver-brazed joint and R-shank design increase the joining area and improve impact resistance.
Bulk Supply and OEM/ODM Support
Established in 2005, SINOLITE has more than 21 years of experience supplying cutting tools to international professional markets. Our quality management system is certified to ISO 9001. Certificate copies and relevant quality documents are available upon request. Our product system covers more than 5,000 SKUs, allowing distributors and importers to consolidate tungsten carbide burrs with other metal cutting tools in one order. Expanded OEM/ODM packing facilities support private-label packaging, customized labels, product combinations and retail-ready carbide burr sets. Contact SINOLITE to request samples, specifications, MOQ and bulk pricing.
Key Advantages of SINOLITE Tungsten Carbide Burrs
◆ Stronger Brazed Joint
The flat-bottom silver-brazed connection provides a larger and more stable joining surface. The R-shank design further increases the brazing area, helping the carbide head withstand impact and vibration during demanding deburring operations.
◆ Low-Temperature Brazing Process
A controlled low-temperature brazing process reduces the risk of excessive heat affecting the tungsten carbide structure. This helps maintain carbide hardness, cutting performance and service life.
◆ Sharp and Consistent Cutting Edges
Each cutting edge is hardened and honed to improve sharpness and cutting stability. The optimized flute geometry supports efficient chip removal, reduces unnecessary vibration and provides more predictable surface results.
Multiple Cuts for Different Materials
Different tooth geometries are available to match the workpiece material and required finish:
◆ Single Cut / M: Fast stock removal on steel, cast steel and cast iron.
◆ Double Cut / MX: Better control, smaller chips and smoother finishing.
◆ Steel Cut / SX: Designed for demanding steel-processing applications.
◆ Aluminum Cut / NF: Wider flutes help reduce clogging on aluminum and other non-ferrous metals.
Complete Shapes and Size Systems
Wholesale tungsten carbide burrs are available in cylindrical, ball, oval, tree, flame, cone, countersink and inverted cone profiles. Metric and inch specifications make it easier for distributors to supply different regional markets.
