Toolex Reamer - Straight Shank - Spiral Flute - Stub Length - Carbide - Through Coolant - H4 - 5.46mm

The Toolex Reamer with straight shank, spiral flute, stub length and carbide construction is a precision bore-finishing tool sized at 5.46 mm. It’s ideal for engineers, machinists, and hobbyists who need clean, repeatable hole sizing in demanding metals. The through coolant design helps manage heat and flush chips away for a smoother finish.

Manufactured to order by Toolex Ltd, this reamer adheres to DIN 8093 with a tolerance of D = ISO H4. The 24–48 hour despatch window reflects its bespoke production, with blanks often in stock ready to machine to your exact spec.

• Carbide substrate for durability: Intermediate precision carbide (K10) provides wear resistance and long tool life in tough materials.
• Left-hand spiral flute with right-hand cutting: Enables efficient chip evacuation and predictable, stable reaming action for accurate holes.
• Through coolant and precision tolerances: Through coolant supports cooling and chip removal, while D = ISO H4 tolerance (DIN 8093) ensures consistently sized bores.

Using this reamer helps you achieve repeatable bore finishes with minimal rework, while the straight shank simplifies setup on standard tool holders. The stub length offers controlled cutting depth, and the robust carbide core delivers dependable performance across production runs, making it a reliable choice for precision hole finishing in both professional and workshop environments.
