Toolex Reamer with a straight shank and spiral flute is designed for precision hole enlargement and finishing in metalworking applications. The 6.88 mm diameter, crafted from HSS-E cobalt, delivers durable, consistent performance across a wide range of materials.

• Diameter: 6.88 mm for precise hole enlargement and finishing with tight tolerances.
• Shank design: Straight shank designed for easy clamping in common tool-holding systems and holders.
• Flute geometry: Spiral flute promotes efficient chip evacuation and smoother cutting action.
• Material: HSS‑E (high-speed steel with cobalt) delivers improved heat resistance and extended tool life.
• Precision: Consistent hole size and surface finish across multiple passes and materials.

This reamer provides reliable, accurate results whether you’re enlarging an existing hole or dialing in a precise diameter. The spiral flute design minimizes chip buildup for steady cutting and reduced downtime, while the straight shank ensures compatibility with a broad range of machining setups—from drills and mills to CNC holders. Ideal for metalworking tasks across steel, aluminum, and other common alloys, it helps you achieve smooth bore finishes and repeatable tolerances with fewer reworks.
