Toolex Reamer - Straight Shank - Spiral Flute - Stub Length - Carbide - Through Coolant - H4 - 17.44mm

The Toolex Reamer is a straight shank, stub-length carbide tool (17.44 mm) designed for through-coolant hole finishing to ISO H4 tolerance (DIN 8093). It features a left-hand spiral flute and right-hand cutting for stable chip control and a clean finish.

Manufactured to order by Toolex Ltd, it typically dispatches within 24–48 hours. This reamer is ideal for engineers, job shops, tradespeople, and hobbyists who need repeatable hole sizes and reliable performance.

• Carbide, stub-length design for durability and precision: Intermediate precision k10 carbide and a stub geometry deliver long tool life and stable diameters across a range of materials, reducing the need for rework.
• Through coolant for efficient cooling and chip control: Coolant passes through the shank to keep the cutting edge cooler, improve finish quality, and extend tool life in demanding applications.
• DIN 8093 / ISO H4 tolerance for repeatable accuracy: Tight hole size control ensures consistent fits and predictable performance across production runs, with minimized deviation between tools.

Used as a precision finishing step, this reamer helps you achieve accurate, smooth-hole finishes with fewer passes, improving assembly reliability and overall workflow. The through-coolant design and stub-length geometry enhance control and repeatability, making it a dependable choice for both high-volume manufacturing and detailed, hands-on projects.
