Toolex Reamer - Straight Shank - Spiral Flute - Stub Length - Carbide - Through Coolant - H4 - 17.25mm

The Toolex Reamer is a straight shank, stub-length carbide reamer designed to finish internal bores with high precision in through-coolant machining. With a 17.25 mm nominal size, it supports tight tolerances while remaining compatible with standard toolholding setups. Its DIN 8093 specification and ISO H4 tolerance help deliver consistent bore finishes across a range of materials.

This reamer is built from intermediate precision carbide (K10) and features a left-hand spiral flute with right-hand cutting, optimized for efficient chip flow in through-coolant environments. Its geometry is selected to maximize stability and surface quality, even in demanding production settings.

• Carbide (K10) construction for durable, repeatable bore finishes: The intermediate precision carbide core provides wear resistance and helps maintain precise hole sizes over many cycles.
• DIN 8093 straight shank with through coolant: Left-hand spiral flute and right-hand cutting work together to improve chip evacuation and reduce built-up edge, while through coolant supports cooler, cleaner cutting.
• ISO H4 tolerance and 24/48 h despatch: Precise 17.25 mm bore tolerance achieved within a manufacturing-to-order process, with despatch typically within 24–48 hours.

Designed for engineers, machinists, and production teams, this reamer helps you achieve reliable, finished bores with minimal rework. The combination of carbide durability, DIN-spec geometry, and through-coolant capability supports smoother setups, faster cycles, and consistently high-quality results—tailored for demanding applications while keeping lead times practical for made-to-order tooling.
