Toolex Carbide Taper Shank Intermediate Reamer H5 12.56mm

The Toolex Carbide Taper Shank Intermediate Reamer is a precision finishing tool designed to bring drilled holes to exact size with a smooth, burr-free finish. Sized at 12.56 mm, it’s ideal for engineers, machinists, tradespeople, and hobbyists who require reliable hole quality in a compact taper-shank form.

Carbide-tipped cutting edge (K10) combined with a left-hand spiral flute and right-hand cutting delivers consistent results to DIN 8051 B tolerance (ISO H5). This item is manufactured to order, with despatch typically within 24–48 hours. If the listing shows “in stock,” that refers to blanks ready to be machined into your reamer.

• Carbide-tipped for extended tool life: The K10 carbide edge resists wear, maintains sharpness, and delivers repeatable, clean hole finishes, reducing rework and downtime.
• ISO H5 tolerance (DIN 8051 B): Precise hole size control ensures better part fit and fewer finishing steps, improving overall workflow and quality.
• Taper shank with left-hand flute and right-hand cutting: Stable alignment and efficient chip flow enhance performance in deeper holes while enabling quick, secure mounting in standard toolholders.

Using this reamer helps you achieve accurate hole sizes on the first pass, minimizes secondary finishing, and improves assembly reliability. The carbide tip provides long-lasting cutting performance in demanding materials, while the strict DIN 8051 B ISO H5 tolerance reduces deviations and rework. Because each reamer is made to order, you can expect careful geometry and surface finish tailored to your needs, with dispatch within 24–48 hours.
