High-Precision Adjustable Rough-Boring Tool for CNC & Machining Centers

Premium Material & Craftsmanship
Hardened high-speed steel (HSS) body with precision-ground carbide inserts ensures durability and extended tool life. Ultra-fine surface treatment reduces friction for smoother cuts.
Innovative Adjustable Design
40-taper shank (BRB-TC-S Arbor 40C) allows quick adjustments (0.1-5mm) for versatile boring depths without tool changes. Ideal for roughing cast iron, steel, and alloy workpieces.
Optimized Performance
Reduces vibration with balanced geometry, delivering superior surface finishes (Ra≤3.2μm). Engineered for high-speed operations (up to 3000 RPM) in heavy-duty CNC lathes and machining centers.
Cost-Efficient Bulk Solution
Direct factory pricing for wholesale buyers—stock up on high-performance tools without premium markups. Ships globally with bulk discounts.
Typical Applications
Automotive cylinder boring, aerospace component machining, mold cavity roughing, and general industrial metalworking.
