Toolex Carbide Taper Shank Intermediate Reamer H5 17.75mm

The Toolex Carbide Taper Shank Intermediate Reamer H5 17.75mm is a precision carbide-tipped reamer designed to size holes with consistent accuracy. It combines left-hand spiral flute with right-hand cutting for efficient material removal and a clean finish, making it suitable for engineers, machinists, toolmakers, and hobbyists who demand reliable hole quality. It follows DIN 8051 B with a tolerance of D = ISO H5, ensuring tight, repeatable diameters. This item is manufactured to order—please allow 24/48 hours for despatch; if a listing shows “in stock,” that refers to blanks ready to be machined into your reamer, while the full range is produced to order.

• K10 carbide tipped for long tool life: The carbide tip delivers superior wear resistance, maintaining precise hole size across multiple uses and challenging materials, reducing downtime for tool changes.
• Left-hand spiral flute with right-hand cutting: Optimized geometry ensures efficient chip removal and stable cutting, producing cleaner holes and reducing finish passes in a variety of workpieces.
• ISO H5 precision tolerance (DIN 8051 B): Provides tight, repeatable hole diameters to standard references, lowering rework and enhancing repeatability in production runs.

Using this reamer helps you achieve dependable hole finishes on the first pass, speeding up setup and downstream assembly. The combination of carbide durability, flute geometry, and strict tolerance translates into fewer rework cycles, predictable performance, and greater confidence in your manufacturing or workshop outcomes—even under demanding materials or higher-volume work.
