Toolex Reamer - Straight Shank - Spiral Flute - Stub Length - Carbide - Through Coolant - H4 - 4.29mm

The Toolex 4.29 mm Straight Shank Spiral Flute Stub-Length Carbide Reamer with Through Coolant is a precision finishing tool designed for clean, accurate hole enlargement in metalworking. Its left-hand spiral flute and right-hand cutting geometry work together for stable material removal and predictable finishes, especially in through-coolant reaming operations. This reamer is built for reliability in demanding setups where hole size and surface quality matter.

Dimensions and standards you can trust: 4.29 mm diameter, straight shank (4 mm), flute length 22 mm, overall length 63 mm, DIN 8093 compatibility, and ISO H4 tolerance. It uses intermediate precision carbide (k10) for durability and repeatable results. Through coolant channels direct coolant to the cutting edge to maximise chip evacuation and cooling during reaming. This item is manufactured to order, with despatch typically within 24–48 hours.

• Flute geometry for stable finishes: Left-hand spiral flute with right-hand cutting delivers controlled material removal and consistent hole finishes.
• Through-coolant design: Coolant passes through the shank to the edge, boosting chip evacuation and thermal control for smoother cuts.
• Carbide (k10) with tight tolerance: Intermediate precision carbide and DIN 8093 / ISO H4 tolerance ensure durable performance and precise hole sizes.

Whether you're setting up precision fixtures or upgrading shop productivity, this reamer helps you achieve accurate, repeatable hole sizes with reliable tool life and straightforward compatibility with standard straight-shank holders.
