Toolex Reamer - Straight Shank - Spiral Flute - Carbide - H5 - 4.42mm

The Toolex Reamer – Straight Shank – Spiral Flute – Carbide – H5 – 4.42 mm is an intermediate precision carbide reamer designed to finish drilled holes to a tight, repeatable size. The 4.42 mm diameter is paired with a carbide chucking-grade (K10) construction for dependable wear resistance and long tool life.

With a straight shank and a left-hand spiral flute paired with right-hand cutting, this reamer delivers clean, accurate bores across a broad range of common engineering materials, including steel, stainless steel, cast iron, non-ferrous metals, and even hardened steels.

• K10 carbide with straight shank: Intermediate precision carbide provides reliable wear resistance and consistent hole finishes for repeated use in a variety of metals.
• Left-hand spiral flute with right-hand cutting: Efficient chip evacuation and smooth bore surfaces, helping achieve a high-quality finish in a single pass.
• H5 tolerance (±0.003 mm): Tight, repeatable sizing that supports interchangeability and reduces the need for rework in precision assemblies.

Using this 4.42 mm reamer helps you achieve precise bore dimensions across common materials, guiding manufacturing workflows toward higher-quality parts with fewer corrective steps and consistent results.
