Toolex Reamer - Stub Type - Spiral Flute - Straight Shank - HSS-E - H4 - 7.10mm

The Toolex Reamer is a stub-type finishing tool designed to bring drilled holes to ISO H4 tolerance with a clean, stable cut. It is built from HSS‑E (M35 cobalt) and sized for a 7.10 mm diameter with a straight shank, making it ideal for repeatable bore finishing across a range of materials.

With a left‑hand spiral flute and right‑hand cutting, this reamer adheres to DIN 8089 standards for precise, reliable results. It is manufactured to order by Toolex Ltd, with dispatch typically within 24–48 hours. If the listing shows in stock, that refers to blanks ready to be machined into the finished reamer, and quantities can be tailored to your production schedule.

• HSS‑E (M35 cobalt) construction: Delivers improved wear resistance and longer tool life for more finished holes between sharpenings.
• DIN 8089 / ISO H4 tolerance: Guarantees precise hole size and reliable interchange with standard gauges and components.
• Left‑hand spiral flute with right‑hand cutting: Promotes efficient chip evacuation and stable cutting for smooth, consistent finishes.

Using the Toolex Reamer provides repeatable bore quality, minimizes finishing time, and reduces the risk of oversize holes in critical assemblies. The robust HSS‑E edge handles demanding materials, while the standard DIN geometry ensures compatibility with existing tooling and measurement workflows. Because it is manufactured to order, you can tailor quantities to your production schedule without compromising on performance.
