TROW And HOLDEN (USA) Tungsten Carbide Tipped Hand Tracer 1" (25mm) Stock 1-1/2 Inch (38mm) Blade Width CHT1112
The Trow & Holden Tungsten Carbide Tipped Hand Tracer (Model: CHT1112) is a premium, heavy-duty stonemasonry tool manufactured in Barre, Vermont, USA. It is engineered primarily for scoring, tracing lines, and splitting the hardest varieties of stone (such as granite, quartzite, and dense limestone)
Model Number: CHT1112
Stock Size: 1 inch (25mm) round steel shank
Blade Width: 1-1/2 inches (38mm)
Blade Edge: High-grade tungsten carbide tip
Striking Head: Standard flat steel head meant for use with steel striking hammers (typically a Masons Driving Hammer or Stone Sledge).
Focal Point Splitting: Unlike a structural chisel that removes bulk material, the hand tracer features a blunt, heavy-bevel angle. This focus concentrates the force of your hammer blow into a single directional stress line across the stone's surface, fracturing it cleanly down the grain.
Superior Blade Geometry: The ultra-hard tungsten carbide insert offers maximum wear resistance. It keeps its sharp profile significantly longer than traditional hardened tool steels when working with highly abrasive materials
Because tungsten carbide is exceptionally hard but inherently brittle, it is susceptible to chipping or fracturing if misapplied:
Align with the Grain: Always prioritize splitting level-bedded stone with the natural grain direction.
Avoid Cross-Grain Prying: Do not use this tool for aggressive cross-grain levering or shaping on hard rock, as lateral stress will fracture the carbide insert.
Flat striking contact: Ensure your hammer face strikes the steel head perfectly true and flat. Off-center or skewed hits can create uneven shockwaves that damage the tool body or the tip.
