Toolex Reamer - Straight Shank - Spiral Flute - Carbide - H5 - 3.85mm

The Toolex Reamer - Straight Shank - Spiral Flute - Carbide - H5 - 3.85mm is an intermediate precision finishing tool designed to tighten hole tolerances in a range of metals. With a 3.85 mm diameter and a straight shank, it fits typical tool holders for quick, secure setup in milling or drilling operations. Built around a carbide (K10) substrate, this reamer delivers consistent sizing and long tool life for production runs or workshop use.

Its left-hand spiral flute paired with right-hand cutting enables efficient chip evacuation and a clean, tight finish. The reamer is engineered to ISO H5 tolerance, similar to DIN 212 B standards, providing reliable hole sizing across compatible materials. The straight shank design supports secure clamping and repeatable results in standard holders.

• K10 carbide for stable, durable cutting: Intermediate precision carbide delivers steady performance in demanding materials, helping reduce wear and extend tool life.
• Left-hand spiral flute with right-hand cutting for efficient chip evacuation: Smooth chip flow minimizes built-up heat and burrs, supporting a cleaner finish in deeper holes.
• Straight shank with ISO H5 tolerance for precise, repeatable results: Straight shank ensures reliable tool holding and hole sizes that align with DIN 212 B-class accuracy.

Used on steels, stainless steels, cast iron, non-ferrous alloys, and hardened materials, this reamer helps you achieve consistent hole diameters with good surface finish. The combination of carbide grade, flute geometry, and tight H5 tolerance supports higher first-pass accuracy, reduces rework, and speeds up production workflows in machining shops and on job sites alike.
