Toolex Reamer - Straight Shank - Spiral Flute - Stub Length - Carbide - Through Coolant - H4 - 11.54mm

The Toolex Straight Shank Reamer with a stub length is a high-precision carbide tool designed for through-coolant reaming of through-holes. Delivering an 11.54 mm diameter with ISO H4 tolerance, it provides reliable bore size control in a range of materials while supporting clean, consistent finishes. Its left-hand spiral flute and right-hand cutting balance chip evacuation and cutting action for stable hole geometry.

Manufactured to order by Toolex Ltd, this reamer ships within a 24–48 hour window, ensuring you receive a fresh tool tuned to your specification. It adheres to DIN 8093 standards and features through coolant to maximize chip removal and thermal management during reaming.

• Through-Coolant Design for Chip Evacuation: Coolant is fed through the shank directly to the cutting edges, improving heat control, reducing chip recutting, and extending tool life.
• Left-Hand Spiral Flute with Right-Hand Cutting: Optimizes chip flow and surface finish in through-holes, helping achieve accurate, repeatable bore sizes.
• Carbide Stub with ISO H4 Tolerance: Intermediate precision k10 carbide construction delivers consistent bore diameter and reliable performance across production runs.

This reamer is ideal for engineers and machinists who need dependable, repeatable hole sizing in production or workshop environments. The combination of through coolant, precise stub-length geometry, and Toolex’s DIN 8093/H4 specification supports efficient workflows, reduced downtime, and high-quality finishing in demanding applications.
