    SPIROL’s Series 24 and Series 25 Inserts are designed for tapered holes with an 8° (included) draft angle and are very similar to SPIROL’s standard Series 14 Inserts, except they are designed for use in alternate hole sizes historically specified in Europe. The Series 25 has the same body style as the Series 24 with the addition of a head for more bearing surface. Both the Series 24 and Headed Series 25 Tapered Inserts are made-to-order in metric thread sizes ranging from M2 to M8.
