OKAZAKI Hand Reamer Model HR0740 Size 7.4 mm.
The OKAZAKI HR Series Model HR0740 is a high-quality hand reamer made from High Speed Steel (HSS). It is designed to finish and size pre-drilled holes to a precise 7.4 mm diameter. The reamer removes rough surfaces left by drilling, corrects hole roundness and concentricity, and delivers a smooth internal surface finish meeting high-precision engineering standards.

Feature

High-Grade HSS: Made from premium Japanese high-speed steel, offering high toughness, wear resistance, and excellent cutting-edge retention.

Straight Flute Design: Straight cutting flutes ensure balanced material removal, reduce chatter, and provide a consistently smooth finish.

Precision Lead Taper: Features a ground lead taper at the tip for self-centering when starting the reaming process, making operation easy and accurate even by hand.

Standard Square Shank: The square shank end is designed to fit securely into a tap wrench, preventing slippage during manual torque transmission.

Application

Used for precision reaming of 7.4 mm drilled holes to improve surface finish and achieve tight tolerances (H7 or specified standards).

Suitable for machinery assembly, maintenance, and pin installation requiring a precision fit.

Compatible with multiple materials including mild steel, cast iron, aluminum, copper, and engineering plastics.

Caution: Always rotate clockwise only (never reverse) and use appropriate cutting fluid/lubricant for best results.
