• ISO H5 tolerance for tight, repeatable holes: The tolerance (-0 to +0.005 mm) ensures precise hole size across parts, reducing rework and improving interchangeability.
• Left-hand spiral flute with right-hand cutting for controlled reaming: This geometry promotes smooth chip evacuation and stable cutting, delivering clean, accurate hole finishes.
• Taper shank design for secure seating and reliable changeovers: The taper shank provides a firm, repeatable fit in compatible tooling setups, minimizing runout and downtime.

Using this reamer helps you achieve repeatable hole quality, reduces rework, and supports consistent performance across production runs. The M2 HSS construction offers durability for demanding tasks, while the tool’s geometry optimizes material removal for efficient workflows. With a clear made-to-order lead time, you can plan purchases with confidence and rely on a fresh, high-quality tool tailored to your needs.
