Toolex Reamer - Straight Shank - Spiral Flute - Stub Length - Carbide - Through Coolant - H4 - 12.78mm

The Toolex Reamer in 12.78 mm is a straight‑shank carbide finishing tool designed for through‑coolant environments, delivering precise hole finish to ISO H4 tolerances on a wide range of metals. With a stub length and DIN 8093 compatibility, it’s built for reliability in production setups and by users who need consistent, repeatable results from a compact reaming solution. The flute arrangement combines a left‑hand spiral with right‑hand cutting to optimize chip control and cutting action, making it suitable for engineers, machinists, and hobbyists alike.

• Carbide, stub design: K10 carbide with a stub length provides a rigid cutting edge and stable hole sizing, helping you achieve consistent finishes over multiple cycles.
• Through coolant with spiral flute: Left‑hand spiral flute and through‑coolant design promote efficient chip evacuation and cooler cutting, reducing tool wear and improving surface quality.
• DIN 8093 compatibility and ISO H4 tolerance: Precisely sized for standard reaming procedures with D = ISO H4 tolerance, and a straight shank that fits common collets and holders for easy integration.

Manufactured to order, this reamer is shipped within 24–48 hours, ensuring you receive the exact 12.78 mm size you need without compromising on accuracy or delivery speed. Its combination of durable carbide, through‑coolant flow, and standardized tolerances supports reliable performance across demanding fabrication and finishing workloads.
