Toolex Carbide Taper Shank Intermediate Reamer H5 20.51mm

The Toolex Carbide Taper Shank Intermediate Reamer is a precision cutting tool designed to resize holes to a tight, consistent diameter of 20.51 mm. With a carbide-tipped (K10) tip and a taper shank, it delivers durable performance in demanding materials while maintaining precise size control.

This reamer features a left-hand spiral flute and right-hand cutting, optimizing chip evacuation and surface finish. It conforms to DIN 8051 B tolerance (D = ISO H5) and is manufactured to order, with a despatch window of 24/48 hours. Note that if the listing says in stock, that refers to blanks; the finished reamer is produced to order.

• Carbide-tipped for extended tool life: The K10 carbide tip resists wear, delivering more usable holes before regrinding, even in tough, abrasive materials.
• Left-hand spiral flute with right-hand cutting: Optimizes chip flow and cutting stability for a cleaner hole and smoother finishes.
• DIN 8051 B tolerance (D = ISO H5) for precise sizing: Tight size control ensures repeatable results and reliable fit in standard tooling and assemblies.

This combination of carbide tooling, exact tolerance, and thoughtful flute geometry means this reamer delivers consistent hole size, reduces rework, and fits securely in standard holders, supporting faster setup and reliable results across a range of materials.
