Toolex Reamer - Straight Shank - Spiral Flute - Carbide - H5 - 4.47mm

The Toolex Reamer, Straight Shank, Spiral Flute, Carbide, H5, 4.47 mm is a precision finishing tool designed to deliver exact, burr-free holes in carbide-grade or tough materials. Its straight shank accepts standard collets and toolholders for quick, secure setup across machines.

Featuring a left-hand spiral flute with right-hand cutting, this reamer maintains steady cutting action and efficient chip evacuation, helping you achieve clean, concentric holes every time. It’s specified as intermediate precision (K10 carbide) and tuned to tight tolerances, with a tolerance of ±0.003 mm and a DIN 212 B‑style finish for reliable, repeatable results.

• Intermediate precision carbide (K10): durable cutting edges and consistent hole finishes that stand up to repetitive production work without frequent regrinds.
• Left-hand spiral flute with right-hand cutting: promotes smooth chip evacuation and stable cutting, reducing bur, chatter, and finish variability.
• H5 tolerance with DIN 212 B alignment: precise 4.47 mm holes that align with standard manufacturing tolerances for dependable interchangeability.

Designed to finish holes with high dimensional accuracy, this reamer helps reduce rework and downtime while delivering repeatable, high-quality results in demanding environments. It pairs well with carbide-grade workpieces and supports consistent performance across shops that require tight control over hole size and surface finish.
