Toolex Reamer - Straight Shank - Spiral Flute - Stub Length - Carbide - Through Coolant - H4 - 4.52mm

The Toolex Reamer is a straight‑shank, 4.52 mm carbide stub‑length finishing reamer designed to bring drilled holes to ISO H4 precision. With a left‑hand spiral flute and right‑hand cutting, plus a through‑coolant design, it delivers clean, accurate finishes and reliable tool life in a range of materials when used in through‑coolant machines.

Manufactured to order by Toolex Ltd, this reamer ships in 24–48 hours and is ideal for shops that require consistent hole sizes and repeatable results, even in demanding production environments. The combination of carbide tooling, DIN 8093 specification, and a straight shank ensures compatibility with standard toolholders while delivering precise performance.

• Intermediate precision carbide (k10) stub reamer: Provides stable hole size and reliable finish over multiple passes, helping reduce rework and downtime.
• Left‑hand spiral flute with right‑hand cutting and through coolant: Optimizes chip evacuation and edge cooling for cleaner holes and longer tool life in through‑fluid machining.
• DIN 8093, ISO H4 tolerance, straight shank: Ensures precise sizing and straightforward seating in common collets and holders for quick, confident setups.

This reamer helps you finish drilled holes to exact dimensions with fewer rework steps, improving workflow and downstream assembly. Its stub length and straight shank provide rigidity in tight setups, while through coolant supports consistent surface finish and higher productivity across steel, stainless steel, cast iron, and non‑ferrous materials.
