UCT Gem Carbide SF-5 1/2-Inch Pointed Tree Carbide Rotary Burr

The UCT Gem Carbide SF-5 1/2-Inch Pointed Tree Carbide Rotary Burr is a specialized rotary grinding and deburring bit engineered for navigating acute angles, grinding narrow V-grooves, blending internal weld seams, and shaping tight corner contours without digging into target workpieces. Rated for operational speeds up to 20,000 RPM on a standard 1/4-inch steel shank, this tungsten carbide head bit features a pointed tree profile and double-cut cross-flute geometry that breaks material into fine chips to eliminate chatter. Outfitted with a 1/2-inch head diameter and a 1-inch length of cut across a 3-inch overall length, this 0.25-pound rotary tool accessory executes high-volume metal removal.

Best Used For:

  • Acute-Angle & V-Groove Joint Grinding: Reaching deep into narrow angled weld preparations and tight interior pointed corners to remove heavy bead material.
  • Internal Contouring & Recessed Deburring: Shaving sharp flash lines and burs from narrow cavities and channels in steel castings and machined components.
  • Engine Cylinder Head & Manifold Porting: 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 (SF-5) Head Profile: Tapered tree geometry provides maximum clearance in narrow V-cuts, acute angles, and sharp fillets without gouging.
  • Double-Cut Cross-Flute Design: Opposing cutting flutes produce granular metal chips to minimize tool chatter and deliver smooth surface finishes.
  • 20,000 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 steel shank mounts 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.
