Toolex Reamer - Straight Shank - Spiral Flute - Stub Length - Carbide - Through Coolant - H4 - 12.03mm

Achieve precise, ready-to-machine holes with the Toolex Reamer — Straight Shank, Spiral Flute, Stub Length, Carbide, Through Coolant, H4 tolerance. This intermediate precision carbide (k10) reamer from Toolex Ltd is designed for engineers, machinists, and fabricators who need tight, repeatable hole sizes in metalworking projects. It features a left-hand spiral flute with right-hand cutting, DIN 8093, and a 12.03 mm diameter to deliver accurate results from the first pass.

Manufactured to order, this reamer is supplied by Toolex Ltd and ships after a 24/48 hour despatch window. Through-coolant design supports efficient chip evacuation and effective cooling, helping maintain tool life and hole quality across production runs.

• Stub-length, straight shank for rigid, stable reaming: The brief length and straight shank provide solid toolholding in tight spaces, reducing runout and improving hole concentricity.
• Left-hand spiral flute with right-hand cutting: Optimized for controlled material removal and predictable hole finish, even in tough alloys.
• Through coolant and ISO H4 tolerance (DIN 8093): Coolant through the tool promotes cooling and chip evacuation, while ISO H4 keeps hole size tight and repeatable.

This reamer helps you deliver consistent hole sizes on faster cycles, reduces rework and scrap, and supports reliable performance in production and repair tasks. With carbide construction and a through-coolant design, you gain durability and repeatable results that you can depend on in everyday workshop and shop-floor applications.
