Toolex Reamer - Straight Shank - Spiral Flute - Stub Length - Carbide - Through Coolant - H4 - 20.07mm

The Toolex Reamer - Straight Shank - Spiral Flute - Stub Length - Carbide - Through Coolant - H4 - 20.07mm is a precision finishing tool designed to bring drilled holes to a tight, repeatable size. With a left-hand spiral flute and right-hand cutting geometry that complies with DIN 8093 and ISO H4 tolerance, it delivers consistent bore finishes across steel, stainless, cast iron, and non-ferrous materials. Manufactured to order, dispatch is typically within 24–48 hours.

• ISO H4 tolerance precision: Delivers repeatable hole sizes with tight fits across production runs.
• Through coolant carbide design: Chips are flushed and the cutting edge stays cooler for cleaner finishes and longer tool life.
• Left-hand spiral flute; straight shank stub length: Provides stable reaming in confined bores with efficient chip evacuation and rigid alignment, reducing deflection and chatter.

This reamer helps you achieve precise hole sizes quickly, enabling reliable mating with fasteners or bushings and reducing the need for rework. The through-coolant design maintains dimensional accuracy by flushing chips and controlling heat, while the stub-length, straight shank provides rigidity in deep or restricted bores for a smoother surface finish. With Toolex, you get a tool manufactured to order with clear despatch timelines, delivering dependable performance when you need it.
