The Trow & Holden 9-Point Tooth Carbide Bushing Chisel (SKU: CJ1212-9L) is a premium, heavy-duty pneumatic stone-working tool engineered for controlled material removal and precise surface finishing. Proudly manufactured in the USA, this industrial-grade chisel is trusted by professional stonemasons, sculptors, and restoration artisans worldwide.
Product Overview
Designed to offer exceptional control, the 9-point bushing chisel is less aggressive than standard 4-point models. It serves as an indispensable mid-to-late stage tool for removing high spots, evening out the coarse textures left by roughing tools, or adding a refined, uniform stippled pattern to smooth or sawed stone surfaces. Equipped with a ultra-durable tungsten carbide tip, this chisel effortlessly withstands the extreme demands of processing hard stone varieties like granite.
Key Features & Benefits
• Gradual Material Removal: Features a 9-point square head layout optimized for smooth, controlled high-spot reduction and texturing.
• Premium Tungsten Carbide Tip: The solid carbide formulation resists wear, heat, and scratching, outlasting standard steel under heavy-duty pneumatic impact.
• Extended Reach: Built with a 9-inch (230mm) overall body length ("L" variant) to offer maximum visibility and accessibility in tight corners or recessed stone joints.
• Standard Pneumatic Fitment: Machined with a 1/2-inch (13mm) diameter shank, making it seamlessly compatible with professional pneumatic air hammers.
