Toolex Die Maker Reamer HSS-E Spiral Flute SS M35 COB 10% - 14-6mm

The Toolex Die Maker Reamer is a precision finishing tool designed to true and finish existing holes with tight control over runout. Built for die makers, machine shops, engineers, and serious hobbyists, it delivers clean, true bores in a range of metals. Made from HSS-E with M35 cobalt, this reamer combines wear resistance with toughness for longer tool life. It features a 10% taper, spiral flute, and right-hand cutting to produce smooth, reliable finishes on every pass.

• 10% taper for smooth entry and precise hole finishing: The gradual diameter reduction toward the tip reduces cutting forces and helps establish accurate bore geometry from start to finish, improving concentricity and reducing need for rework.
• HSS‑E with M35 cobalt for extended wear life: Cobalt-enriched high-speed steel offers superior hardness and wear resistance, delivering longer tool life when reaming harder materials and delivering consistent results over many cycles.
• Spiral flute with right‑hand cutting for efficient chip evacuation: The spiral geometry carries chips away from the cutting edge, promoting a clean bore and reliable finishes with less clogging and plate-out.

Tolerances for this reamer are designed to deliver repeatability: D = ± 0.05 mm, d = ± 0.05 mm, L = ± 1 mm, d1 = h8. With these specifications, you can achieve tight, production-ready holes that improve part fit, reduce assembly effort, and streamline manufacturing workflows across molds, dies, and precision housings. The combination of cobalt-enhanced material and optimized flute geometry makes this reamer a dependable choice for demanding applications where consistent quality matters.
