Wholesale Carbide Bur Bits Double Cut Tungsten Rotary Burrs Industrial Grinding Tools

Standard Type-F oval head design fits curved surfaces perfectly, realizing dead-corner grinding for inner grooves and radians without blind spots.

Solid one-piece tungsten carbide construction features high hardness and chipping resistance, no tooth loss or rapid wear under high-speed grinding.

Cross double-cut flutes ensure smooth chip removal, no material clogging or tool burning for higher cutting efficiency.

Standard 6mm straight shank fits most pneumatic and electric die grinders with excellent universal compatibility.

Suitable for machining various metals including stainless steel, carbon steel, cast iron, alloy steel and cast aluminum.

Precisely CNC ground cutting edges guarantee consistent dimensions and superior surface finish on workpieces.

Optimized dynamic balance brings low vibration during high-speed rotation for stable and labor-saving handheld operation.

Much longer service life than high-speed steel burrs, effectively reducing long-term consumable costs for bulk processing.

Custom OEM available for extended shanks, single-cut aluminum teeth and non-standard sizes.

Each piece undergoes dynamic balance inspection before delivery to avoid runout and improve operation safety at high speed.
