Set of ten ER-25 metric collets. Sizes include: 3mm, 4mm, 5mm, 6mm, 8mm, 10mm, 12mm, 14mm, 15mm, 16mm.

ER-25 collets have a major diameter of 1.02" (26 mm) and a length of 1.34" (34 mm). The collets in this set have a clamping range of 3.0 mm - 16 mm (0.118" - 0.630").

ER collets are made from high grade tool steel, hardened and ground to close tolerance. Kerf cuts allow the collet to expand and contract as needed within the specific clamping range to securely hold the tool or workpiece.

*Collet must be assembled into a collet chuck nut before inserting into the collet chuck.

Customer Reviews (4.8 / 5 · 5 reviews)

Brian ★★★★★

I was pleasantly surprised by how precisely these collets fit my router—the 8mm one holds the bit securely without any wobble. The set covers a wide range of common sizes, which saves me from buying individually.

Jason ★★★★★

The 10mm collet holds my bits snug with zero wobble, and the 26mm diameter fits my spindle nut perfectly. I’ve used three sizes so far and they all seat cleanly without any sticking.

Robert ★★★★★

The runout on these ER-25 collets is impressively low, I checked a few sizes with a dial indicator and they were all within a tenth. The 3mm one holds a drill bit absolutely snug, and the whole set is a solid upgrade from my old generic ones.
