Toolex Reamer - Straight Shank - Spiral Flute - Carbide - H5 - 3.93mm

Toolex Reamer - Straight Shank - Spiral Flute - Carbide - H5 - 3.93 mm is a high-precision reaming tool designed to finish holes to tight, repeatable tolerances. Built on an intermediate precision carbide (K10) substrate with a straight shank, this reamer delivers reliable rigidity and consistent bore sizing in a compact, easy-to-handle form.

The tool uses a left-hand spiral flute and right-hand cutting action to optimize chip evacuation and cutting stability, helping you achieve smooth bore finishes and dependable results with minimal rework. It targets tight bore control with a tolerance of ±0.003 mm, aligned with the DIN 212-B style approach for predictable, repeatable performance.

• Carbide construction (K10) with straight shank: Provides durable rigidity and long tool life when used in standard collet or chuck holders, helping maintain bore accuracy over many cycles.
• Left-hand spiral flute with right-hand cutting: Ensures efficient chip removal and stable cutting, delivering cleaner bores and reduced heat buildup during use.
• Tight ±0.003 mm tolerance (DIN 212-B style): Enables repeatable bore sizes across parts, reducing rework and supporting tighter quality control in production runs.

Designed for engineers, machinists, and technicians who require reliable bore finishing, this reamer supports straightforward setup, consistent results, and durable performance that helps keep downtime low while delivering precise, repeatable bore quality.
