Description

UCT Gem Carbide SG-3 3/8-Inch Pointed Tree Solid Carbide Rotary Burr

The UCT Gem Carbide SG-3 3/8-Inch Pointed Tree Solid Carbide Rotary Burr is a specialized rotary grinding and deburring bit engineered for cleaning out acute-angled corners, grinding narrow V-cuts, blending internal welded seams, and deburring complex metal geometries without binding in tight spaces. Rated for operational speeds up to 25,000 RPM on a standard 1/4-inch shank, this solid tungsten carbide bit features a pointed tree flame-like profile and double-cut cross-flute geometry that breaks material into fine chips to eliminate chatter. Outfitted with a 3/8-inch head diameter and a 3/4-inch length of cut across a 2-1/2-inch overall length, this 0.15-pound rotary tool accessory executes precision metal removal.

Best Used For:

  • Acute-Angle & V-Groove Joint Grinding: Accessing narrow angled weld preparations and sharp interior corners to remove excess bead material.
  • Complex Mold & Die Cavity Deburring: Removing sharp flash lines and burs from narrow recessed cavities in steel castings and machined parts.
  • Engine Cylinder Head & Porting Modifications: Shaping and smoothing narrow internal runner transitions and curved port walls in automotive cylinder heads.

Key Performance & Safety Features

  • Tungsten Carbide Cutting Head: High-density carbide composition brazed to a hardened steel shank maintains cutting edge hardness under intense heat.
  • Pointed Tree (SG-3) Flame-Like Profile: Tapered tree geometry provides maximum clearance in narrow V-cuts, acute angles, and sharp fillets.
  • Double-Cut Cross-Flute Design: Opposing cutting flutes produce granular metal chips to minimize tool chatter and deliver smooth surface finishes.
  • 25,000 Maximum RPM Speed Rating: Precision-balanced construction accommodates pneumatic and electric 1/4-inch die grinders at full operating speed.
  • Standard 1/4-Inch Steel Shank: Precision-ground shank inserts securely into standard 1/4-inch collets to eliminate rotational runout.
  • Multi-Metal Substrate Compatibility: Cuts efficiently through structural steel, cast iron, stainless steel, brass, bronze, and aluminum.
