Toolex Reamer - Straight Shank - Spiral Flute - Stub Length - Carbide - Through Coolant - H4 - 17.10mm

The Toolex Reamer - Straight Shank - Spiral Flute - Stub Length - Carbide - Through Coolant - H4 - 17.10mm is an intermediate precision carbide stub reamer designed for through-hole finishing with tight diameter control. It combines a straight shank and a left-hand spiral flute with right-hand cutting to deliver stable, predictable material removal and a smooth, burr-free hole finish. Through coolant enhances chip evacuation and cooling during reaming, helping sustain tool life and consistent size. Manufactured to DIN 8093 and finished to ISO H4 tolerance, this reamer is built for reliable performance in production environments. Each unit is made to order by Toolex Ltd, with a dispatch window of 24–48 hours.

• Carbide construction (K10) with stub length: for extended tool life and consistently stable hole sizes in demanding materials, reducing rework and downtime.
• Left-hand spiral flute with through coolant: efficient chip evacuation and cooling paired with a controlled cutting action for cleaner holes and longer tool life in through-hole applications.
• DIN 8093 compliance and ISO H4 tolerance: ensures precise hole diameter and reliable interchangeability with standard tooling across multiple machines and setups.

This reamer is designed to help you achieve repeatable, high-quality hole finishes with minimal setup effort. The combination of carbide durability, through-coolant operation, and strict tolerance control supports faster cycle times, fewer reworks, and consistently accurate results in serial production and critical assemblies.
