Toolex Reamer - Straight Shank - Spiral Flute - Carbide - H5 - 4.30mm

Finishing precision where it matters: Toolex Reamer - Straight Shank - Spiral Flute - Carbide - H5 - 4.30 mm delivers a true 4.30 mm bore with a final, smooth finish. Made from intermediate precision carbide (K10) and featuring a straight shank, this reamer provides reliable alignment on CNC and manual machines. The left-hand spiral flute, paired with right-hand cutting, promotes effective chip evacuation and stable cutting in a compact tool that fits standard collets and toolholders.

Designed for engineers, machinists, and workshop technicians, it’s ideal for finishing holes in metal and plastic that require tight tolerances and consistent results. With a tolerance of ±0.003 mm, this reamer supports repeatable production and helps ensure correct fits in assemblies without over-sizing.

• Carbide (K10) construction for longer tool life: The carbide body resists wear and maintains cutting geometry for more holes between regrinds, delivering dependable performance in demanding applications.
• Left-hand spiral flute with right-hand cutting: Optimizes chip evacuation and stability, reducing clogging and giving a cleaner bore finish across a range of materials.
• ±0.003 mm tolerance (H5 class): Provides tight, repeatable bore size to support accurate fits and high-quality assembly outcomes.

This reamer helps you finish holes to exact size with consistent results, improving workflow, reducing rework, and delivering reliable performance across production runs and precision assemblies.
