Toolex Reamer - Straight Shank - Spiral Flute - Stub Length - Carbide - Through Coolant - H4 - 18.79mm Milling Cutter Arbors you can trust consistent holeThe Toolex Straight Shank Reamer is a stub length carbide finishing tool designed to finish drilled holes to ISO H4 tolerance. With an 18. 79 mm diameter, it uses intermediate precision carbide (k10) and a left hand spiral flute paired with right hand cutting for controlled, consistent material removal. Through coolant directs coolant to the cutting edge and clears chips for a smoother bore finish, helping you achieve precise results in a single pass.
