OKAZAKI Machine Reamer MR4000 Size 40.0 mm.
OKAZAKI Model MR4000 is a premium machine reamer from Japan, manufactured by OKAZAKI SEIKI. Made of High-Speed Steel (HSS), it is designed for fine reaming of pre-drilled holes to achieve the highest accuracy at 40.0 mm., focusing on cylindrical precision and smooth hole surface quality.
Feature
High-Speed Steel (HSS): Manufactured from Japanese industrial-grade high-speed steel, highly wear-resistant and retaining cutting edges exceptionally well under operating heat.
Precision Tolerance: Dimensions controlled according to JIS standards, ensuring accurate tolerances for engineering component assembly.
Straight Flute Design: Straight cutting flutes ensure stable reaming and easy re-sharpening.
Excellent Surface Finish: Eliminates roughness from drilling, delivering a mirror-smooth inner hole surface.
High Rigidity: High tool rigidity reduces vibration during operation, ensuring perfect roundness of the reamed hole.
Application
Used for fine reaming (finishing) to enlarge pre-drilled holes to a high-precision 40.0 mm. size.
Ideal for tight-fit applications such as large shaft holes, machine dowel pin holes, or bearing housing bores.
Compatible materials: Mild steel, cast iron, alloy steel, aluminum, copper, and other metal alloys.
Compatible with milling machines, lathes, or radial drilling machines.
