Toolex Reamer with a straight shank and spiral flute is designed for professionals who need precise hole enlargement and finishing in a range of metals. Made from HSS-E, it combines durability and heat resistance to deliver consistent, smooth holes in demanding machining environments.

• Diameter: 4.005 mm
• Shank type: Straight shank for easy clamping in collets, drills, and tool-holders
• Flute design: Spiral flute for efficient chip evacuation and reduced chip buildup during cutting
• Material: HSS-E (high-speed steel with cobalt) for enhanced wear resistance and heat tolerance
• Applications: Precision hole enlargement and finishing across a range of metals and alloys
• Performance: Delivers accurate hole sizes with a smooth finish and consistent depth control

Utilize this reamer in CNC mills, drill presses, and other precision machining setups to achieve tight tolerances and high-quality bore finishes. The cobalt-enhanced HSS construction supports extended tool life under demanding cutting conditions, while the spiral flute design promotes steady chip evacuation for cleaner cuts. With its straight shank, it offers broad compatibility across common toolholding systems, making it a reliable choice for repeatable bore sizing and surface-smooth results in a variety of materials.
