Toolex Reamer - Straight Shank - Spiral Flute - Stub Length - Carbide - Through Coolant - H4 - 7.77mm

The Toolex Reamer is a straight‑shank, carbide stub‑length reamer designed to finish through‑holes to a precise 7.77 mm with ISO H4 tolerance. Its left‑hand spiral flute and right‑hand cutting provide stable, predictable performance, while the through‑coolant design keeps chips moving and the cutting edge cooler for consistent finishes.

Supplied by Toolex Ltd, this is a made‑to‑order tool—please allow 24–48 hours for despatch. Built for reliability in demanding applications, it suits engineers, machine operators, and workshop technicians who need repeatable hole perfection in a compact, easy‑to‑set‑up package.

• Carbide k10 construction: Delivers strong wear resistance and stable hole dimensions, helping you achieve consistent results over many cycles.
• Left‑hand spiral flute with right‑hand cutting on a straight shank: Optimizes chip evacuation and cutting control in through‑hole work, with compatibility to common toolholders.
• Through‑coolant, DIN 8093 / ISO H4 7.77 mm specification: Through‑coolant keeps the cut clean and cool, while tight tolerance ensures reliable fits and reduces rework.

This reamer is tailored for accuracy and durability in through‑hole finishing. Its rigid stub length and carbide edge shorten cycle times, improve surface finish, and deliver repeatable, high‑quality bore sizes—even in challenging materials and demanding production environments.
