• Left-hand spiral flute with right-hand cutting: Balanced cutting action and predictable material removal for clean, consistent bore finishes.
• HSS (M2) material: High hardness and wear resistance for longer tool life in demanding metalworking tasks.
• ISO H5 tolerance with D = -0 +.005 mm: Delivers precise hole sizes to tight specifications with repeatable results.

In use, you’ll achieve accurate 17.37 mm bores with a smooth finish and repeatable performance across jobs. The taper shank offers secure, reliable seating in standard holders, while the M2 HSS resists wear for longer service between changes.
