Toolex Reamer - Straight Shank - Spiral Flute - Stub Length - Carbide - Through Coolant - H4 - 12.19mm

The Toolex Reamer is a straight-shank carbide finishing tool designed to bring through-holes to precise ISO H4 tolerances with confidence. Sized at 12.19 mm in diameter, it uses intermediate precision carbide (k10) and a stub-length body for rigid, stable cutting. The tool features a left-hand spiral flute and right-hand cutting, and it is designed to run with through coolant to keep the cutting edge cool and chips moving away from the hole. It is manufactured to order by Toolex Ltd, with an estimated despatch window of 24–48 hours.

• Through‑coolant delivery through the shank: Direct coolant to the cutting edge for better temperature control and improved chip evacuation in through-holes.
• Carbide stub‑length with durable construction: Intermediate precision carbide (k10) provides long tool life and consistent hole size in demanding materials, with a compact form that enhances rigidity.
• DIN 8093 / ISO H4 precision: Left‑hand spiral flute and right‑hand cutting meet established standards for reliable, repeatable hole finishes and smooth surface quality.

This reamer helps you achieve accurate, uniform bore finishes with minimal pass wear, supporting faster setup, reduced rework, and repeatable results across a range of materials. The through-coolant design and stable stub-length geometry translate to dependable performance in production or workshop environments, giving you the confidence to specify this Toolex reamer for tight-tolerance through-holes.
