UCT Gem Carbide Rotary Burr SA-5 1/2 Inch (1/4 Inch Shank Tungsten Carbide Cylindrical Double Cut 20000 Max RPM Weld Grinding Steel Porting)

UCT Gem Carbide SA-5 1/2-Inch Cylindrical Carbide Rotary Burr

The UCT Gem Carbide SA-5 1/2-Inch Cylindrical Carbide Rotary Burr is a rotary grinding and deburring bit engineered for heavy weld removal, engine head intake porting, sheet metal edge smoothing, and 90-degree corner dressing. Rated for operational speeds up to 20,000 RPM on a standard 1/4-inch steel shank, this tungsten carbide head bit features double-cut cross-flute geometry that breaks stock into small chips to reduce chatter. Outfitted with a 1-inch head diameter and a 1-inch length of cut across a 2-3/4-inch overall length, this 0.25-pound rotary tool accessory executes high-volume metal removal.

Best Used For:

• Heavy Weld Seam Grinding: Smoothing large structural weld beads flush on carbon steel, stainless steel, and iron fabrications.
• Automotive Engine Porting & Polishing: Enlarging, shaping, and clearing obstructions inside cast iron and aluminum intake manifold runners.
• Structural Steel Corner & Edge Deburring: Removing sharp burs from cut steel plates and dressing right-angle internal shoulders.

Key Performance & Safety Features

• Solid Tungsten Carbide Head: High-density carbide composition maintains cutting edge hardness under extreme friction heat.
• Double-Cut Cross-Flute Design: Opposing cutting flutes produce granular metal chips to minimize tool chatter and deliver controlled finishes.
• 20,000 Maximum RPM Rating: Precision-balanced construction accommodates pneumatic and electric 1/4-inch die grinders at full operational speeds.
• Cylindrical SA-5 Profile Geometry: Straight cylindrical body without end cut facilitates flat surface stock removal and shoulder squaring.
• Hardened 1/4-Inch Steel Shank: Precision-ground steel shank mounts securely into standard 1/4-inch collets to eliminate rotational runout.
• Ferrous & Non-Ferrous Substrate Versatility: Cuts efficiently through structural steel, cast iron, brass, bronze, and aluminum alloys.

Technical Specifications

Pro-Tip: Operate the die grinder at steady high speeds near 20,000 RPM while maintaining light, continuous tool movement; applying excessive pressure reduces cutting efficiency and causes thermal buildup on the tungsten carbide teeth.
