Toolex Reamer - Straight Shank - Spiral Flute - Carbide - H5 - 8.42mm

The Toolex 8.42mm straight‑shank carbide reamer is an intermediate‑precision tool designed to size holes with consistent accuracy in steel, stainless steel, cast iron and non‑ferrous materials. The 8.42 mm diameter and straight shank fit standard collets and reaming setups, and this item is manufactured to order—please allow 24/48 hours for despatch.

With a left‑hand spiral flute and a right‑hand cutting action, it provides efficient chip evacuation and a clean, controlled reaming process that helps minimize chatter and produce stable hole finishes across common engineering steels and related alloys.

• Left‑hand spiral flute for efficient chip removal: Chips are guided away from the cutting edge during reaming, reducing clogging and heat build‑up for smoother, more reliable hole sizing.
• K10 carbide with ISO H5 tolerance: Intermediate‑precision carbide delivers repeatable hole sizes and longer tool life, helping you meet tight tolerances with confidence.
• Straight shank with a 8.42 mm diameter and 10° helix: A rigid drive in standard tooling and a slight helix angle aids cutting efficiency and chip breakout for consistent results in steel, stainless steel, cast iron and non‑ferrous workpieces.

This combination of precise sizing, durable carbide and a chip‑friendly geometry helps you finish holes to specification faster, reduces rework, and improves overall workflow in production or repair environments. The reamer is designed for dependable performance across a range of common materials, making it a trustworthy choice for engineers, machinists and workshops seeking repeatable results.
