Toolex Reamer - Straight Shank - Spiral Flute - Stub Length - Carbide - Through Coolant - H4 - 12.64mm

The Toolex Reamer - Straight Shank - Spiral Flute - Stub Length - Carbide - Through Coolant - H4 - 12.64mm is a precision carbide reamer designed to finish holes to exact size with reliability. Its stub-length, straight shank design offers rigidity in tight bores, while the left-hand spiral flute works with right-hand cutting for efficient material removal across a range of materials. Through coolant channels flush chips away from the cutting edge, helping maintain a clean hole and extend tool life.

This reamer is manufactured to order by Toolex Ltd and conforms to DIN 8093 with a tolerance of ISO H4, ensuring consistent hole sizes and interchangeability with other tooling in standard setups. The 12.64mm diameter, combined with through-coolant and carbide construction, makes it suitable for precision finishing in both soft and hardened materials.

• Carbide stub-length design for rigidity: Intermediate precision carbide (k10) and a stub length minimize deflection, delivering stable, accurate hole sizes even in challenging workpieces.
• Through coolant with left-hand spiral flute: Chips are flushed through the flute while cutting, reducing heat and burr formation for smoother finishes and longer edge life.
• DIN 8093 / ISO H4 tolerance with straight shank: Precisely sized to H4 tolerance and compatible with standard toolholders, ensuring repeatable results across multiple setups.

Used in engineering, manufacturing, and workshop environments, this reamer helps improve hole quality, reduce deburring time, and maintain consistent performance across jobs. Its carbide construction, through coolant, and standardized tolerances support reliable, repeatable results andSource-friendly upkeep in demanding applications.
