Toolex Reamer - Straight Shank - Spiral Flute - Stub Length - Carbide - Through Coolant - H4 - 17.87mm

Toolex Reamer - Straight Shank - Spiral Flute - Stub Length - Carbide - Through Coolant - H4 - 17.87mm is a high-precision carbide reamer designed to finish internal holes to ISO H4 tolerance in through-coolant setups. Manufactured from intermediate precision carbide (K10), this stub-length tool delivers the rigidity needed for accurate bore finishing in production and quality-critical applications.

Ideal for engineers, machinists, tradespeople, and hobbyists who require dependable, repeatable bore sizes and clean finishes, the tool combines a left-hand spiral flute with right-hand cutting, through-coolant delivery, and DIN 8093 compliance to ensure consistent geometry across reaming tasks. This item is manufactured to order, with despatch typically 24/48 hours to meet project timelines.

• Left-hand spiral flute, right-hand cutting: Delivers stable, controlled reaming with a clean finish and efficient chip evacuation through the flute, even in through-coolant operations.
• Through-coolant delivery: Coolant travels through the shank and flute to keep the cutting edge cool and flush chips away, helping extend tool life and maintain bore quality.
• DIN 8093 compliant, ISO H4 tolerance: Ensures precise bore sizing and compatibility with standard reaming processes, delivering repeatable results in production runs.

With these features, you gain reliable, repeatable bore finishes that meet tight tolerances, longer tool life to reduce downtime, and a through-coolant design that keeps bores clean and production moving smoothly. The stub-length, straight shank configuration provides rigidity in deep holes, making this reamer well-suited for both high-volume manufacture and precise, detail-driven work.
