Precision Twist Drill 7466223 Carbide Abrasive Bur SA-30FM

Product Description

The PRECISION TWIST DRILL 7466223 is a carbide abrasive bur with a cylinder flat-end head profile, designed for aggressive material removal in rotary die grinder and pneumatic tool applications. Conforming to industry specification SA-30FM, it features an Aluma Cut tooth style engineered for efficient chip evacuation in soft, gummy materials. The 3/8-inch cutting diameter and 1/4-inch shank diameter make it a standard fit for most die grinders used by machinists, fabricators, HVAC sheet metal techs, and maintenance trades. Rated to 30,000 RPM, this bur handles high-speed passes without loading. The uncoated carbide head delivers consistent cutting geometry throughout its service life.

This bur is suited for deburring, shaping, and finishing operations on cast aluminum and glass fiber reinforced polymer components. It performs well in automotive, HVAC fabrication, composite repair, and general metalworking environments where soft or abrasive-resistant materials demand a dedicated Aluma Cut geometry. The 3/4-inch length of cut provides adequate reach for contouring recessed areas without sacrificing rigidity. At 2.5 inches overall length, it balances reach and control in confined work areas.

Key Features

• SA-30FM industry specification — cylinder with flat-end head geometry
• Aluma Cut tooth style optimized for cast aluminum and glass fiber reinforced polymers
• Carbide head construction for durability and consistent edge retention
• 30,000 RPM maximum speed rating for high-speed die grinder use
• 1/4-inch shank diameter fits standard die grinder collets
• 3/4-inch length of cut for controlled material removal in recessed areas

Compatibility

Designed as an OEM-style replacement and standard-fit abrasive bur for die grinders and rotary tools accepting a 1/4-inch shank collet, conforming to SA-30FM industry specification.

Installation Notes

Installation is performed by machinists, fabricators, or maintenance technicians using a die grinder or rotary tool with a matching 1/4-inch collet. Secure the shank fully into the collet and tighten to the tool manufacturer's specified torque before operation. Inspect the bur for cracks or damage before each use and never exceed the 30,000 RPM maximum speed rating. Always wear appropriate eye protection and secure the workpiece before beginning material removal.
