Toolex Reamer - Straight Shank - Spiral Flute - Carbide - H5 - 4.29mm

The Toolex Reamer, 4.29 mm, is a straight-shank carbide finishing tool engineered for precise, repeatable bore sizing. Built with an intermediate precision carbide (K10) grade and a left-hand spiral flute with right-hand cutting, it delivers clean, accurate holes in a range of materials while maintaining stable sizing across multiple passes. Its design aligns with DIN 212 B-style tolerancing, offering reliable performance in both setup-heavy and quick-turn applications.

• Carbide, K10 grade for durable, consistent sizing: The intermediate precision carbide composition provides wear resistance and long tool life, helping maintain hole accuracy over many cut cycles.
• Left-hand spiral flute with right-hand cutting: This combination enhances chip evacuation and cutting direction control, promoting smoother finishes and reduced risk of clogging in deep or long reach bores.
• Tight tolerance of ±0.003 mm (DIN 212-B style): Expect repeatable hole diameters from part to part, enabling reliable assembly and consistent performance in precision machining work.

Designed for professionals and serious hobbyists, this reamer helps you achieve accurate bore dimensions with confidence. Its straight shank seats securely in standard holders, and the 4.29 mm size makes it suitable for finishing pre-drilled holes to a precise diameter, reducing the need for subsequent sizing operations and improving overall workflow efficiency.
