Toolex Reamers with straight shank and a spiral flute deliver precise hole enlargement and finishing, designed for machinists who need reliable bore accuracy across a range of materials. This 3.70 mm HSS-E reamer pairs durable cobalt-infused steel with efficient chip evacuation for consistent, smooth holes.

• Size: 3.70 mm nominal diameter for accurate hole adjustment and finishing.
• Material: High-speed steel with cobalt (HSS-E) for enhanced wear resistance and heat tolerance.
• Flute Design: Spiral flute to promote efficient chip removal and steady cutting action.
• Shank Type: Straight shank for broad compatibility with multiple tool holders and setups.
• Accuracy: Engineered for tight tolerances and a clean bore finish across materials.
• Applications: Ideal for enlarging existing holes or achieving precise diameters in metals and plastics.

This reamer is a reliable choice for shops requiring consistent performance and straightforward integration into standard milling or drilling workflows. The combination of HSS-E durability and the spiral flute design helps minimize chip buildup, reduce heat, and extend tool life. For best results, pair with appropriate lubrication and maintain steady cutting conditions to achieve repeatable, high-quality hole finishes.
