Precision Twist Drill 7466260 Carbide Bur 5/8 in

Product Description

The PRECISION TWIST DRILL 7466260 is a double-cut carbide abrasive bur with a ball nose cylinder head profile. It is designed for aggressive material removal and fine-detail finishing on hard metals and alloys. The carbide head delivers consistent cutting performance across a 5/8-inch cutting diameter, with a 1-inch length of cut and a 7-inch overall length. The 1/4-inch round shank fits standard die grinders and rotary tools. At a maximum rated speed of 20,000 RPM, this bur handles demanding material removal tasks efficiently. Machinists, tool and die technicians, and fabricators use this type of bur for deburring, porting, contouring, and weld dressing operations.

This bur is suited for use on steel, stainless steel, cast iron, non-ferrous metals, high-temperature alloys, and other hard materials. It performs well in both production and maintenance environments where precise metal removal is required. Typical applications include deburring drilled or cast holes, blending weld seams, enlarging or shaping cavities, and surface preparation prior to inspection or coating. The ball nose cylinder profile allows access to contoured surfaces and inside radii that flat-end burs cannot reach.

Key Features

• Ball nose cylinder head profile for contouring, blending, and cavity work
• Double-cut tooth style removes material faster and leaves a smoother finish than single-cut
• Solid carbide head — uncoated — handles steel, stainless steel, cast iron, and high-temperature alloys
• 5/8-inch cutting diameter with a 1-inch length of cut for substantial stock removal per pass
• Rated to 20,000 RPM for use with standard pneumatic and electric die grinders
• 1/4-inch shank diameter fits the most common collet sizes on die grinders and flex-shaft tools

Compatibility

Designed for use in any die grinder, rotary tool, or flex-shaft machine fitted with a 1/4-inch collet. Conforms to SC-60DC-X industry specification for this bur geometry and cut style.

Installation Notes

Installation is performed by machinists, fabricators, and maintenance technicians using standard die grinders. Secure the 1/4-inch shank fully into the collet before operation and verify the collet nut is tightened to the tool manufacturer spec. Always wear eye protection and appropriate PPE when operating rotary burs. Do not exceed the 20,000 RPM rated speed, and ensure the workpiece is clamped or secured before beginning material removal.
