It’s built for engineers, machinists, and workshop users who require repeatable, high-quality hole finishes in metalworking projects.

Made from M2 high-speed steel, this reamer uses a left-hand spiral flute with right-hand cutting for controlled material removal. It carries ISO H5 tolerance (-0 to +0.005 mm) and conforms to BS 328/4 standards. As a made-to-order item by Toolex Ltd, despatch is typically within 24–48 hours of order.

• Taper shank for secure seating: A precise taper shank seats firmly in your spindle or collet, reducing runout and chatter to deliver consistent bore alignment and repeatable hole finishes.
• Left-hand spiral flute with right-hand cutting: This combination promotes efficient chip control and predictable material removal for a smoother bore surface and reliable results across materials.
• M2 HSS with ISO H5 tolerance: High-speed steel offers durability and wear resistance, while the ISO H5 tolerance (-0 to +0.005 mm) ensures holes finish at the intended size with minimal secondary machining.

Using this reamer helps you achieve precise bore sizes in fewer passes, reduces rework, and speeds up production cycles. The standard length and robust taper seating support quick, confident setup on a range of machines, while the made-to-order production ensures you receive a tool tailored to this specification within the stated despatch window.
