Toolex Reamer - Straight Shank - Spiral Flute - Stub Length - Carbide - Through Coolant - H4 - 12.74mm

The Toolex Reamer is a straight shank, spiral-flute carbide finishing tool designed to bring holes to ISO H4 tolerance with precision and consistency. At 12.74 mm in diameter, it’s ideal for engineers, machinists, and workshops that require repeatable bore sizes in through-hole applications. The left-hand spiral flute and right-hand cutting deliver controlled material removal for a smooth, accurate bore.

This reamer is supplied by Toolex Ltd and manufactured to order, with a despatch window of 24–48 hours. It’s built for reliability in production or prototyping work, and its through-coolant design helps flush chips and manage heat during cutting.

• Through‑coolant delivery for clean, consistent holes: coolant flows through the tool to cool the cutting edge and evacuate chips, helping maintain hole quality and extend tool life.
• Carbide k10, stub-length construction: the stub length and carbide material provide rigidity and wear resistance for durable, repeatable reaming in demanding materials.
• DIN 8093, H4 tolerance: built to tight ISO H4 tolerances ensures reliable bore sizes across parts, reducing rework and simplifying finishing processes.

Designed for dependable performance, this reamer supports a smooth workflow from setup to finished holes. Use it when you need precise, repeatable bore dimensions, efficient chip evacuation, and durable cutting performance in through‑hole reaming tasks.
