Toolex Reamer - Straight Shank - Spiral Flute - Carbide - H5 - 4.18mm

The Toolex Reamer is a straight-shank carbide reamer with a 4.18 mm diameter, designed to deliver precise, smooth bore finishes in a wide range of materials. Its left-hand spiral flute and right-hand cutting orientation help produce clean bore surfaces with predictable guidance, making it suitable for production work, prototyping, and field repairs.

Key construction and tolerance details include intermediate precision carbide (K10) for durable wear resistance and a DIN 212-B style tolerance of ±0.003 mm, ensuring consistent bore sizing across jobs. The straight shank is compatible with common toolholders, enabling straightforward setup in standard machining workflows.

• Carbide (K10) construction for extended life: Intermediate precision carbide provides wear resistance and stable cutting performance for repeated use across materials.
• Left-hand spiral flute with right-hand cutting: Enhances chip evacuation and delivers a smooth bore finish, improving consistency in deeper holes.
• DIN 212-B tolerance ±0.003 mm: Tight, repeatable bore sizing that supports reliable fits and interchangeability in precision work.

This reamer helps you achieve accurate bores with minimal rework, thanks to its robust carbide composition, precise sizing, and straightforward mounting. It supports efficient manufacturing and reliable results across a variety of projects, from engineering prototypes to production runs.
