AMB Elektrik Collets for Routers โ 3, 3.175, 4, 6, 8mm
The Kress collet chuck 8mm clamps 8mm-shank cutting tools inside AMB-Elektrik (Kress) router spindles. It gives even, centred clamping pressure so the tool runs true instead of wobbling in the cut.
ER11 Collets 1-7mm for CNC Router Spindle Tool Clamping
ER11 collets clamp a cutting tool's shank inside the spindle's ER11 nut, giving even, centred grip on shanks from 1mm to 7mm. They are the standard tool-holding format on small and mid-size CNC routers and engraving machines, and the correct size must be matched to the shank in use.
ER16 Collets for CNC Spindle Tool Clamping, 1-10mm
ER16 collets clamp cutting tool shanks from 1mm to 10mm inside CNC spindles fitted with an ER16 taper. Each size grips one specific diameter, so choosing the correct collet keeps runout low and the tool centred.
ER20 Collets – Precision Clamping 1mm to 13mm
ER20 collets clamp tool shanks from 1mm to 13mm inside ER20 spindles and chucks. Each size grips one diameter for centred, chatter-free holding, letting a single nut cover drills, end mills, and engraving cutters.
ER25 Collet Set 1-16mm for CNC Router Tooling
The ER25 collet set clamps round-shank cutters from 1mm to 16mm in diameter, with each collet sized 28mm OD x 34mm long to fit standard ER25 nuts and holders. It gives CNC routers and milling spindles secure, low-runout tool holding across a wide range of cutter sizes.
