• Carbide construction (k10) with stub-length design: Delivers long tool life and rigidity in tight or deep holes, helping maintain precise hole size over multiple uses.
• Left-hand spiral flute with right-hand cutting: Optimizes chip evacuation and cutting stability, producing clean, round holes with consistent finishes.
• Through coolant, DIN 8093 geometry, and ISO H4 tolerance: Supports effective cooling and chip removal while delivering repeatable hole diameters to strict ISO tolerances in a range of common materials.

Using this reamer helps improve workflow by delivering reliable hole quality with minimal rework, especially in through-coolant setups and production environments that demand consistent results. The straight shank ensures compatibility with standard toolholders, while the DIN 8093 geometry and ISO H4 tolerance provide repeatable, dependable performance across steel, stainless steel, cast iron, and non-ferrous materials. Manufactured to order, it arrives ground to the exact 4.11 mm size for your operations.
