Toolex Reamer - Straight Shank - Spiral Flute - Carbide - H5 - 12.34mm

Toolex Reamer - Straight Shank - Spiral Flute - Carbide - H5, 12.34mm is an intermediate precision carbide reamer designed to finish holes to exact diameters with a clean, repeatable surface finish. It features a straight shank and a left-hand spiral flute with right-hand cutting, delivering controlled material removal and dependable performance on a range of metals when used with standard toolholders. The 12.34mm diameter is designed to achieve tight tolerances in your holes and maintain consistent sizing across parts.

This reamer uses intermediate precision carbide (K10) and ISO H5 tolerance, closely aligned with the DIN 212-B family of straight shank reamers for reliable interchangeability and accuracy. It is manufactured to order, so please allow 24–48 hours for despatch, with stock related to blanks rather than the finished reamer. This combination supports durable performance and consistent hole sizing in production runs.

• Left-hand spiral flute with right-hand cutting: Optimizes chip evacuation and delivers a controlled, smooth hole finish in a single pass, enhancing precision and reducing rework.
• Carbide grade K10 with ISO H5 tolerance: Provides repeatable hole sizes and longer tool life compared with standard steel reamers, increasing reliability on critical parts.
• Manufactured to order with 24–48 hour despatch: Ensures consistent quality and alignment with production schedules, helping you plan builds without long waits.

This reamer helps you achieve precise holes, reduces downtime from rework, and supports efficient workflows in professional shops and by serious hobbyists alike. Its straight shank design simplifies toolholding integration, while carbide construction delivers durability for repeatable, trustworthy results across demanding applications.
