Sworker 10Pcs Carbide Burr Set 1/4 Shank w/Clear Box Max Head Dia

The Sworker 10-Piece Tungsten Carbide Burr Set gives metalworkers, welders, and fabricators a versatile rotary tool kit for shaping, carving, deburring, and material removal. With its 1/4-inch shank, this kit is built to access confined spots where larger grinding wheels or discs cannot reach.

Each bit features a double-cut tungsten carbide head. This geometry grinds material cleanly, reduces chip size, and leaves a finer surface finish than single-cut alternatives. Sworker includes three distinct head diameters (6mm, 8mm, and 10mm) across the 10-piece assortment, allowing you to tackle broad material removal or fine profiling across steel, concrete, wood, stone, plastic, and weld seams. The heads operate with lower noise and reduced vibration for comfortable, steady hand control.

Compatibility is straightforward for standard workshop setups. The 1/4-inch (6.35mm) shanks fit electric and pneumatic die grinders from brands like DeWALT, Milwaukee, Makita, and Ingersoll Rand. The full set comes packed in a 4-inch by 3.2-inch by 0.6-inch slotted plastic clamshell box along with a reference manual to assist with operation.

One key limitation to keep in mind is tool sizing. These bits require a true 1/4-inch collet and will not fit rotary tools equipped with a 6mm collet. Additionally, the kit focuses on smaller head diameters up to 10mm, so users needing larger industrial profiles may need additional bits.

Verdict: The Sworker 10-Piece Carbide Burr Set is a dependable choice for DIYers and tradespeople who need controlled material removal across metal, wood, or stone. It is especially suitable for anyone using 1/4-inch air or electric die grinders in tight work spaces.

• Piece Count: 10 burrs, 1 plastic box, 1 manual, 1 paper box
• Material: Tungsten carbide
• Shank Diameter: 1/4 inch (6.35mm)
• Head Diameters: 6mm, 8mm, 10mm
• Cut Type: Double cut
• Storage Box Dimensions: 4 x 3.2 x 0.6 inches
• Tool Compatibility: 1/4-inch electric or air die grinders (DeWALT, Milwaukee, Makita, Ingersoll Rand)
• Incompatible With: 6mm collets

A great fit if you:

• Use a 1/4-inch electric or pneumatic die grinder for metal fabrication or welding cleanup
• Need to grind, chamfer, port, or deburr in tight spaces where grinding wheels cannot fit
• Work across a wide variety of materials including steel, wood, stone, plastic, and concrete
• Prefer double-cut bits that produce fine finishes and smaller waste chips

Consider something else if you:

• Use a rotary tool that only accepts 6mm collets
• Require burr heads larger than 10mm for heavy, broad-surface stock removal

Will these burrs fit a rotary tool with a 6mm collet?
No. The shanks measure 1/4 inch (6.35mm) and do not fit 6mm collets.

What materials can this burr set cut?
The tungsten carbide bits work on metal, steel, welds, wood, stone, concrete, and plastic for tasks like deburring, shaping, carving, and grinding.

What is included in the package?
You receive 10 tungsten carbide burrs, a slotted clear plastic clamshell box (4 x 3.2 x 0.6 inches), an instruction manual, and a paper box.

What is the benefit of a double-cut burr?
The double-cut pattern creates a finer surface finish than single-cut designs while reducing the size of the material chips produced during cutting.
