BB2055 PRO Carbide Reamer 7.54–9.26mm | Spiral Flute | CNC Machining

Spiral Flute Design for Smooth Cutting Recommended for reaming steel and alloy materials with hardness up to HRC60. Spiral flute geometry promotes consistent chip evacuation and reduces cutting resistance during CNC reaming operations. Nano Coating on Cutting Edge Nano-coating applied to cutting edges for improved wear resistance and thermal stability. Suitable for continuous cutting in steel, cast iron, and pre-hardened materials. Integral Cemented Carbide Manufactured from micrograin cemented carbide for improved wear resistance and toughness. Designed to reduce tool change frequency in high-volume CNC reaming applications. Fully Ground Cutting Edge All cutting edges are precision ground. Spiral groove geometry improves chip flow and reduces vibration during cutting, contributing to dimensional stability and reduced tool breakage risk. Fixed Straight Shank Straight shank with precision-ground surface for secure chuck engagement. Chamfered tail for universal compatibility with standard CNC tool holders. Applicable Materials Aluminum alloy • Die-cast aluminum • Stainless steel • Carbon steel • Cast iron • Pre-hardened steel
