Toolex Reamer - Straight Shank - Spiral Flute - Stub Length - Carbide - Through Coolant - H4 - 6.81mm

Produce exact 6.81 mm holes with the Toolex Straight Shank Reamer — a stub-length, carbide tool designed for through-coolant operation. Built for reliability, it delivers consistent bore sizes and smooth finishes in a range of metals and alloys. Ideal for engineers, machinists, toolmakers, and workshops that demand tight, repeatable tolerances.

It features a left-hand spiral flute and right-hand cutting action for efficient chip evacuation and clean bore surfaces. The reamer adheres to DIN 8093 and ISO H4 tolerance, using intermediate precision carbide (k10) to maintain stability and accuracy over many cycles. Supplied by Toolex Ltd, this item is manufactured to order; despatch typically occurs within 24–48 hours after order confirmation.

• Intermediary precision carbide (k10) construction: Delivers stable hole sizing with ISO H4 tolerance for consistent fits across production runs.
• Left-hand spiral flute with right-hand cutting: Optimizes chip evacuation and surface finish for through-coolant reaming.
• Through coolant and stub-length straight shank: Through-coolant cooling keeps cutting edges cooler and longer life, while the stub length and straight shank provide rigidity and compatibility with standard toolholders.

By delivering stable, accurate bores quickly and consistently, this reamer reduces rework and downtime, improves part quality, and streamlines reaming steps in mixed-material workflows. The through-coolant design minimizes heat buildup and extends tool life, even on high-volume runs.
