Toolex Reamer - Straight Shank - Spiral Flute - Stub Length - Carbide - Through Coolant - H4 - 4.22mm

The Toolex 4.22 mm Straight Shank Reamer is an intermediate precision carbide (k10) stub tool designed for finishing through-holes with tight, repeatable size control. Its geometry combines a left-hand spiral flute with right-hand cutting for stable, clean finishes across a range of materials, including steel, stainless steel, cast iron, and non-ferrous alloys.

Manufactured to order—please allow 24 to 48 hours for despatch. The reamer adheres to DIN 8093 and ISO H4 tolerance standards, ensuring precise hole sizes and reliable interchangeability in production environments. A through coolant design directs coolant to the cutting edge, helping reduce heat and chip buildup for longer tool life and better surface finish in demanding applications.

• Left-hand spiral flute with right-hand cutting: Encourages efficient chip evacuation and consistent hole finishes in through-holes.
• Through coolant design: Delivers coolant directly to the cutting edge, reducing heat and prolonging tool life.
• DIN 8093, ISO H4 carbide (k10) tolerance: Delivers precise, repeatable hole sizes with dependable performance across materials.

Using this reamer helps you finish drilled holes with greater accuracy, reducing rework and speeding up production cycles. The rigid stub length and carbide construction resist wear, delivering reliable results across multiple jobs and material types while maintaining consistent dimensional control.
