It is essential to use the correct size collet for the tool shank diameter. First make sure you are looking at the right type of collet to fit the spindle on your machine and then select the required size from either the metric or imperial range.

Use the table below to select the right size of ER collet. The example spindles shown are just a small selection of where these collets can be used. Even if your spindle is listed the best way to check compatibility is to compare the dimensions in the table with one of your existing collets.

Collet Type	D1 (mm)	L (mm)	Example Spindle Types
ER16	17	27.5	Colombo RC73, 1.5kw (2HP)
ER20	21	31.5	Perske KRS35 (1/2" capacity), 1.2kw, 1.7kw
ER25	26	34	Elte TMPE3, 2.2kw (3HP) Colombo RC90, 4.1kw (5.5HP)
ER32	33	40	Elte TMPE4 & TMPE5, 3.7kw (5HP), 4.5kw (6HP), 7kw (10HP) HSD 4kw (5HP), 7kw (10HP) Colombo RC110, 10kw

Collets should be replaced every 3 - 6 months. This will avoid problems associated with worn collets including:

poor cut quality
reduced tool life
premature tool breakage
tools working loose whilst cutting
