Toolex Reamer - Straight Shank - Spiral Flute - Stub Length - Carbide - Through Coolant - H4 - 19.57mm

The Toolex Reamer – Straight Shank, Spiral Flute, Stub Length, Carbide, Through Coolant (H4, 19.57 mm) is a purpose-built finishing tool designed to reliably finish pre-drilled holes in metal. Ideal for engineers, machinists, buyers, tradespeople, hobbyists, and technicians, it delivers consistent hole sizes with a clean surface finish in a single pass when used with a compatible machine and through‑coolant system. This reamer is manufactured to order by Toolex Ltd and typically despatched within 24–48 hours.

With a 19.57 mm diameter and compliance to DIN 8093, it uses an intermediate precision carbide (k10). The left-hand spiral flute paired with right-hand cutting supports reliable chip control and a predictable cutting action, while the through coolant design directs coolant directly to the cutting edge to preserve hole quality and extend tool life.

• Through‑Coolant design: Direct coolant through the shank to the cutting edges improves chip evacuation and temperature control, yielding cleaner holes and longer tool life.
• Left‑hand spiral flute with right‑hand cutting: Provides stable, predictable reaming action and a clean finish across common steels and alloys.
• DIN 8093 / ISO H4 carbide (K10): Delivers tight dimensional control and wear resistance for repeatable results across production runs.

This reamer helps professionals finish pre‑drilled holes with high accuracy, reduces rework, and enhances overall workflow. The combination of through‑coolant capability, rigid stub‑length form, and carbide material supports longer tool life and consistent performance in demanding applications.
