Toolex Reamer - Straight Shank - Spiral Flute - Stub Length - Carbide - Through Coolant - H4 - 17.29mm

The Toolex Reamer is a straight shank, carbide stub reamer with a left-hand spiral flute and right-hand cutting, designed for precise through-hole finishing. With a 17.29 mm nominal diameter, it delivers a clean, accurate bore size to ISO H4 tolerance when used in conjunction with through-coolant tooling. This reamer is supplied by Toolex Ltd and is suitable for engineers, machinists, and workshop environments that demand reliable hole quality across metal, including steel and non-ferrous materials.

• Carbide (K10) substrate with through coolant: High-ward wear resistance combined with through-coolant delivery helps maintain dimensional accuracy and extends tool life for repetitive precision reaming tasks.
• Left-hand spiral flute, right-hand cutting: Optimizes cutting action and chip evacuation, providing stable performance and smooth hole finishes in through-hole operations.
• DIN 8093 / ISO H4 tolerance: Ensures a tight, consistent bore size that meets demanding engineering fits, reducing rework and improving part interchangeability.

This product is manufactured to order, with an estimated dispatch window of 24–48 hours. The combination of a stub length for rigid control, through-coolant capability, and precise ISO H4 tolerance makes it a dependable choice for production runs and quality-critical assemblies, where consistent results and minimal downtime matter.
