Toolex Reamer - Straight Shank - Spiral Flute - Stub Length - Carbide - Through Coolant - H4 - 8.88mm

The 8.88 mm Toolex Reamer is a straight-shank carbide stub reamer with through coolant, built for precise finishing of drilled holes. It uses an intermediate precision carbide (k10) substrate and features a left-hand spiral flute with right-hand cutting to deliver consistent hole sizes and smooth finishes in a range of common materials. This reamer is manufactured to order by Toolex Ltd., with an approximate despatch window of 24–48 hours; if a listing shows “in stock,” that refers to blanks ready to be machined into your reamer.

• Carbide substrate (k10) for long tool life: Carbide resists wear and maintains dimensional accuracy through repeated reaming passes, helping you reduce tool changes and maintain consistent results over time.
• Left-hand spiral flute with right-hand cutting: Optimized for chip control and stable cutting in through-coolant applications, contributing to cleaner holes and reliable finishes.
• DIN 8093 / ISO H4 tolerance (8.88 mm): Tight, repeatable size control that supports precise assemblies and dependable interchangeability across production runs.

This reamer enhances your workflow by delivering repeatable, accurate holes with minimal deburring and rework. The combination of carbide durability, through-coolant delivery, and strict tolerance standards helps you finish parts faster, with consistent quality from start to finish—whether you’re prototyping, producing in volume, or performing maintenance and repairs.
