Toolex Reamer - Straight Shank - Spiral Flute - Stub Length - Carbide - Through Coolant - H4 - 11.21mm

Toolex Reamer - Straight Shank - Spiral Flute - Stub Length - Carbide - Through Coolant - H4 - 11.21mm is a high-precision carbide reamer designed to finish through-holes with tight ISO H4 tolerances. Supplied by Toolex Ltd, this stub-length tool is built for reliable bore finishing with a straight shank and an 11.21 mm nominal diameter for accurate alignment in standard toolholders.

It features a straight shank (10 mm) with a flute length of 28 mm and an overall length of 80 mm, delivering rigidity and stable cutting. The reamer uses a left-hand spiral flute and right-hand cutting action, paired with through coolant to improve chip evacuation and edge cooling, all in compliance with DIN 8093 and ISO H4 tolerance requirements. This product is manufactured to order; please allow 24–48 hours for despatch.

• Carbide (k10) construction: Intermediate-precision carbide with a stub-length body delivers durable performance and repeatable hole finishes over more cycles than standard HSS reamers.
• Through coolant with straight shank and left-hand spiral flute: Enhanced chip control and cooling for smoother reaming, reduced heat build-up, and cleaner bore walls.
• DIN 8093 compliance and ISO H4 tolerance at 11.21 mm: Precise sizing that fits standard reamed holes and ensures consistent results across production runs.

This reamer is designed to deliver reliable, repeatable results in a range of materials and production environments, helping you reduce rework, improve bore quality, and maintain steady workflow from setup to final finish.
