Toolex Reamer - Straight Shank - Spiral Flute - Stub Length - Carbide - Through Coolant - H4 - 10.78mm

The Toolex Reamer is a straight-shank, intermediate-precision carbide (k10) stub reamer designed for finishing through-holes with tight, repeatable size control. It features a left-hand spiral flute with right-hand cutting and through coolant, conforming to DIN 8093, and is sized at 10.78 mm in diameter with ISO H4 tolerance. Supplied by Toolex Ltd, this tool is manufactured to order, with a despatch window of 24–48 hours to ensure you receive the exact specification you need for critical bore work.

• Through coolant for reliable chip removal: The through-coolant design channels coolant along the flute to evacuate chips, reduce heat buildup, and extend tool life in through-hole finishing.
• Left-hand spiral flute with right-hand cutting: This combination promotes stable chip flow and predictable bore quality, helping achieve consistent finishes across a range of materials.
• Carbide (k10) with ISO H4 tolerance: The hard-wearing carbide substrate delivers long wear life and rigidity, while the tight ISO H4 tolerance ensures precise hole diameters for reliable assembly.

Using this reamer helps you finish holes to exact sizes with a smooth bore, minimizing rework and speeding up production. The stub length adds rigidity to reduce deflection during finishing passes, even in longer through-holes, while the order-to-despatch model guarantees you receive the precise 10.78 mm reamer you specified within a predictable timeframe.
