UCT Gem Carbide Rotary Burr SF-1 1/4 Inch (1/4 Inch Shank Solid Tungsten Carbide Tree Shape Radius End Double Cut 30000 Max RPM Weld Grinding)

UCT Gem Carbide SF-1 1/4-Inch Tree Shape Radius End Solid Carbide Rotary Burr

The UCT Gem Carbide SF-1 1/4-Inch Tree Shape Radius End Solid Carbide Rotary Burr is a specialized rotary grinding and deburring bit engineered for navigating acute angles, grinding narrow V-grooves, blending internal radiused weld seams, and shaping tight corner contours without digging into target workpieces. Rated for operational speeds up to 30,000 RPM on a standard 1/4-inch shank, this solid tungsten carbide bit features a tree-shape radius-end head profile and double-cut cross-flute geometry that breaks material into fine chips to eliminate chatter. Outfitted with a 1/4-inch head diameter and a 5/8-inch length of cut across a 2-3/4-inch overall length, this 0.12-pound rotary tool accessory executes precision metal removal.

Best Used For:

• Acute-Angle & V-Groove Joint Grinding: Reaching deep into narrow angled weld preparations and tight interior radiused corners to remove excess bead material.
• Internal Contouring & Recessed Deburring: Shaving sharp flash lines and burs from narrow cavities and radiused 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

• Solid Tungsten Carbide Construction: Single-piece carbide formulation maintains cutting edge hardness under intense frictional heat.
• Tree Shape Radius-End (SF-1) Head Profile: Rounded tree geometry provides smooth clearance in narrow V-cuts, acute angles, and rounded fillets without gouging.
• Double-Cut Cross-Flute Design: Opposing cutting flutes produce granular metal chips to minimize tool chatter and deliver smooth surface finishes.
• 30,000 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.

Technical Specifications

Pro-Tip: Guide the radius-end tree head smoothly through narrow V-grooves without jamming; maintaining steady die grinder speeds near 30,000 RPM with light pressure prevents tooth chipping and ensures even stock removal.
