Toolex Reamer - Straight Shank - Spiral Flute - Carbide - H5 - 5.20mm

The Toolex 5.20 mm straight shank reamer delivers ISO H5 hole accuracy in a compact finishing step, built on an intermediate precision carbide (K10) substrate for reliable performance across common engineering materials. Designed for machinists, toolmakers, and workshops that need tight size control without sacrificing workflow, its straight shank fits standard tool holders for straightforward integration into existing setups.

With a left-hand spiral flute and right-hand cutting, this reamer provides predictable chip control and smooth hole finishes. It is manufactured to order and ships within 24–48 hours from stocked blanks, offering a practical balance between precision and production schedules. Suitable for use on steel, stainless steel, cast iron, non-ferrous alloys, exotic metals, and hardened steel, it supports a wide range of finishing applications.

• Carbide (K10) construction: Stable, wear‑resistant material that maintains consistent cutting performance across demanding metals.
• Left-hand spiral flute with right-hand cutting: Effective chip evacuation and reliable hole geometry for smooth finishes and reduced reworking.
• ISO H5 tolerance (DIN 212 B equivalent): Tight dimensional control ensures precise hole size and dependable part fit.

Using the 5.20 mm reamer helps you achieve repeatable hole sizes with high surface quality, minimizes downtime from rework, and integrates easily with standard tooling. Its robust carbide body and proven geometry support reliable results across a broad range of materials, making it a dependable choice for production and prototype work alike.
