Toolex Reamer - Stub Type - Spiral Flute - Straight Shank - HSS-E - H4 - 12.16mm

Toolex Reamer - Stub Type - Spiral Flute - Straight Shank - HSS-E - H4 - 12.16mm is an intermediate-precision reamer designed to finish holes to a tight, repeatable diameter. Made from HSS-E (M35 cobalt) and configured as a stub reamer with a straight shank, it delivers durable performance in a range of materials. Supplied by Toolex Ltd, this 12.16 mm bore reamer adheres to DIN 8089 and ISO H4 tolerancing for consistent results in production or workshop settings.

This reamer is an ideal choice for engineers, machinists, and technicians who need reliable bore finishing that maintains size and finish across steel, stainless steel, cast iron, and non‑ferrous materials. The 12.16 mm size is designed for precise resizing or finishing of bored holes, helping you reduce rework and improve part interchangeability. 12.16 mm diameter guidance and the Toolex DIN 8089 specification underpin predictable, repeatable results in your tooling setup.

• HSS-E (M35 cobalt) construction: durable tool steel that resists wear for longer life and stable sizing through multiple passes in tough materials.
• Left-hand spiral flute with right-hand cutting: geometry optimized for controlled material removal and smoother bore finishes, aiding chip evacuation and consistency.
• 12.16 mm diameter with DIN 8089 and ISO H4 tolerance: precise bore sizing that aligns with industry standards for repeatable results across compatible tooling and processes.

The combination of material, geometry, and standard tolerances helps you achieve accurate bores with minimal downtime, keep tight tolerances on production runs, and rely on Toolex’s established reamer design for consistent performance in a wide range of machining applications.
