Toolex Reamer - Straight Shank - Spiral Flute - Stub Length - Carbide - Through Coolant - H4 - 13.34mm

The Toolex Reamer, a straight shank carbide stub reamer with a through-coolant design, is built for finishing pre-drilled holes to strict ISO H4 tolerance (13.34 mm). With a left-hand spiral flute and right-hand cutting, it delivers precise, clean holes in steel, stainless steel, cast iron, and non-ferrous materials. Supplied by Toolex Ltd and manufactured to order, it’s designed for reliable, repeatable results in demanding production environments.

• Through-coolant delivery for cooler, cleaner holes: Coolant flows through the tool to flush chips and maintain cutting edge integrity, helping achieve consistent diameters and smoother finishes in challenging materials.
• Left-hand spiral flute with right-hand cutting: Optimizes cutting dynamics to reduce thrust and improve hole quality, especially in harder or tougher workpieces, while preserving dimensional stability.
• Stub-length, straight shank, carbide (K10) accuracy: Provides rigid tool guidance, dependable repeatability, and long wear life, all within DIN 8093 standards and ISO H4 tolerance for reliable production performance.

This reamer is designed to slot directly into standard toolholding and coolant setups, enabling quick, confident tool changes and consistent hole finishes across batches. Its intermediate precision carbide core supports durable performance in real-world machining, helping you minimize rework and maintain tight process control from part to part.
