OZ Type Collets
From £19.20 ex VAT
A full range of metric and imperial size OZ 1831 and OZ 1833 type collets for use with Perske spindles. These differ to the ER collets in that they are made to take an exact size cutter shank.
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 type of OZ collet. The example spindles shown are just a 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 |
| OZ 1831 | 14.4 | 26 | Perske KRS35 1.2kw & 1.7kw |
| OZ 1833 | 19.7 | 34 | Perske KNS50 2.2kw (3HP) Perske VS60 5kw (6.7HP) |
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.
