PFERD 21901501 HSS Rotary Bur Set, 6-Piece, 3 mm Shank, 6 mm Head, Cylindrical/Ball/Tree/Flame/Round Arch Shapes

For metalworkers who need a compact, versatile bur assortment without buying individual cutters, this six-piece HSS set from PFERD covers the most frequently used shapes in one plastic box. The 3 mm shank fits straight grinders and flexible shaft drives, while the standard cross cut removes material quickly on steels, stainless steel, cast iron, non-ferrous metals, and plastics. Unlike single-purpose burs, the mixed geometry here—cylindrical with end cut, ball nose, tree with radius end, pointed tree, flame, and round arch—handles deburring, chamfering, milling, and fine machining in tight areas.

Highlights

• Six essential HSS bur shapes for everyday metal finishing
• 3 mm shank diameter for standard collet chucks
• Standard cross cut for efficient stock removal and good surface finish
• Supplied in a durable plastic box for organised storage
• Made in Germany by PFERD, a leader in abrasive and cutting tools

In daily use

The set is aimed at workshops, maintenance teams, and model makers who regularly work on steel, cast steel, stainless steel (INOX), cast iron, non-ferrous metals, and plastics. The 6 mm head diameter reaches into corners and narrow grooves that larger burs cannot access. Because all pieces share the same shank size, switching between shapes is quick—no need to change collets. The uncoated HSS body keeps the cutting edges sharp and predictable, and the standard cross cut balances aggressiveness with control. For best results, use with a straight grinder or flexible shaft.
