Toolex Die Maker Reamer HSS-E Spiral Flute SS M35 COB 8% - 12-5mm

The Toolex Die Maker Reamer is a precision HSS-E spiral flute reamer designed for die and mold work, delivering tight bore control and a clean finish in a single step. It’s ideal for engineers, machinists, and technicians who need dependable bore accuracy across a range of materials.

Built from HSS-E (M35 cobalt), this reamer offers enhanced wear resistance and heat tolerance for longer tool life in demanding applications. It features an 8% taper, a spiral flute, and a right-hand cut to ensure smooth entry, efficient chip evacuation, and stable cutting. Tolerances are D ± 0.05 mm; d ± 0.05 mm; L ± 1 mm; d1 = h8.

• 8% taper for precise bore sizing: Helps achieve consistent hole dimensions deeper in the bore, reducing post-reaming finishing steps and improving assembly fit.
• HSS-E cobalt construction for longer life: M35 cobalt enhances wear resistance and heat tolerance so the tool stays sharp longer and reduces tool changes.
• Spiral flute with right-hand cut for efficient cutting: Promotes smooth cutting, easy chip evacuation, and a clean bore finish with less clogging.

Use this reamer to achieve repeatable, accurate bores in die making, mold work, and precision machining. By delivering consistent diameter control and a smooth finish, it speeds up setup, reduces rework, and helps you meet tight tolerances across production runs.
