Toolex Reamer with a straight shank and spiral flute delivers precise hole enlargement and finishing for professional metalworking and machining. Designed for machinists, toolmakers, and fabrication shops, it combines durable cobalt-infused high-speed steel with an efficient flute geometry to deliver consistent, smooth holes.

• Diameter: 12.18 mm
• Material: HSS-E (high-speed steel with cobalt) for enhanced hardness and heat resistance
• Flute Design: Spiral flute for efficient chip evacuation and improved cutting action
• Shank Type: Straight shank for broad compatibility with common tool-holding systems
• Tolerance & Finish: Ground geometry engineered for accurate hole sizing and repeatable results

Toolex Reamers are known for accuracy and consistent performance. The cobalt-infused steel stands up to heat during finishing passes, helping maintain precise dimensions and a clean surface finish. The straight shank and spiral flute work together to reduce chip buildup, lower cutting forces, and minimize chatter, making it suitable for a wide range of materials—from softer alloys to harder steels. This reamer is ideal for enlarging drilled holes to a precise 12.18 mm diameter or bringing an existing hole to a final, tight tolerance with a smooth bore. For best results, use proper lubrication and steady feeds to maximize tool life and hole quality.
