Toolex Die Maker Reamer HSS-E Spiral Flute SS M35 COB 5% - 16-8mm

The Toolex Die Maker Reamer is a precision cutting tool designed for die makers, mold shops, and precision machinists. This spiraled, right-hand reamer finishes holes to tight, dependable sizes with a smooth surface finish, making it ideal for finishing dies, fixtures, and hard-material cavities.

Constructed from HSS-E cobalt steel (M35), it delivers enhanced wear resistance for longer life in tough materials. The tool features a 5% taper and a spiral flute for efficient material removal and stable cutting, with precise tolerances: D ± 0.05 mm, d ± 0.05 mm, L ± 1 mm, and d1 = h8.

• 5% taper for precise hole finishing: progressive cutting action along the length helps achieve accurate hole sizes with reduced finishing passes and consistent results across workpieces.
• Spiral flute with right-hand cut for smooth chip evacuation: efficient removal of material and reduced clogging in deep or narrow holes, leading to cleaner finishes and fewer tool interruptions.
• HSS-E cobalt alloy (M35) for extended wear life: increased hardness and wear resistance deliver longer tool life in hard steels and die components, improving reliability and reducing downtime.

This combination supports a dependable, efficient workflow: you get consistent hole tolerances, fewer rework steps, and longer tool life, which translates into faster setup, fewer tool changes, and improved overall performance in die-making and precision machining.
