Toolex Reamer - Straight Shank - Spiral Flute - Carbide - H5 - 4.59mm

The Toolex Reamer - Straight Shank - Spiral Flute - Carbide - H5 - 4.59mm is a high-precision finishing tool designed to bring drilled holes to a precise 4.59 mm diameter. Built on an intermediate precision carbide (K10) substrate, it delivers durable wear resistance and stable hole size for repeatable reaming in everyday shop work. The straight shank is compatible with standard toolholders, making it easy to integrate into existing setups.

Its left-hand spiral flute paired with right-hand cutting promotes efficient chip evacuation and smooth bore finishes, reducing friction and improving surface quality in the hole. The reamer adheres to DIN 212-B style conventions with an H5 tolerance, achieving a tight size control of ±0.003 mm so you can trust consistent results across parts and runs.

• K10 carbide substrate: Provides durable wear resistance and stable hole size for long service life in routine reaming tasks.
• Left-hand spiral flute with right-hand cutting: Enhances chip evacuation and delivers cleaner, more uniform bore finishes with less resistance during entry.
• DIN 212-B/H5 tolerance (±0.003 mm) for 4.59 mm: Ensures tight, repeatable size control and reliable fits in precision workpieces.

Designed for engineers, machinists, and shop floor operators, this reamer helps you finish holes to exact size quickly and consistently. The combination of carbide durability, precise tolerance, and a straightforward straight-shank design supports faster setup, reduced rework, and dependable performance across production runs.
