60 Degrees Cone Carbide Burr SJ Die Grinder Bits On 1/4″ Shanks

Tungsten carbide burrs are widely used across industrial sectors including machinery, aviation, automobile, shipbuilding, chemical engineering, and process engraving. Their primary applications include:

1. Fine processing of various metal molds, such as shoe molds and similar tooling.
2. Process engraving of metals and non-metals, including mold engraving and trimming of craft gifts.
3. Cleaning flash, burrs, and welds from castings, forgings, and weldments — commonly used in machine-casting plants, shipbuilding yards, and automobile factories.
4. Chamfering, rounding, and groove processing of mechanical parts; pipe cleaning; and finishing of inner hole surfaces — typical in machinery factories and repair shops.
5. Repair of impeller runners, such as those found in car engine manufacturing.

Carbide rotary burrs are primarily used with power tools or pneumatic tools (they can also be mounted on machine tools). The recommended driving speed is generally 6,000–50,000 RPM.

1. Double cut is more suitable for lower-density materials such as wood, plastic, and aluminum. Its crossed cutting lines enable fast chip removal, though it can clog easily in grain gaps during grinding and engraving — making it the better choice for softer materials.
2. Single cut is not ideal for soft materials, as debris tends to clog the cutting grooves, resulting in shallower texture depth and reduced cutting capacity. It is therefore better suited for hard materials such as iron, copper, and steel.

These solid carbide 60-degree cone-shaped burrs are designed for deburring, enlarging, and chamfering countersink bolt holes, repairing damaged 60-degree threads and V-grooves, and finishing other angular metal and material surfaces. They can also be used to prepare metal edges for welding fabrication.
