Toolex Reamer - Taper Shank - Spiral Flute - Standard Length - HSS - H5 - 16.71 mm

The Toolex Reamer is a taper shank, spiral-fluted HSS reamer designed for reliable intermediate-precision hole finishing. With a 16.71 mm diameter and standard length, it suits a wide range of milling and drilling operations where consistent hole size and surface quality matter.

Featuring a left-hand spiral flute and right-hand cutting, it provides efficient chip evacuation and controlled material removal. ISO H5 tolerance (-0 to +0.005 mm) under BS 328/4 standards ensures precise, repeatable holes. The taper shank delivers secure seating in compatible toolholders, reducing runout and helping achieve better finishes. Made to order by Toolex Ltd, it ships within a 24–48 hour despatch window to fit tight shop schedules.
