HSK63F ER32 70L Tool Holder

HSK63F ER32 Tool Holder

A precision HSK63F tool holder fitted with the versatile ER32 collet system, giving you a wide clamping range (typically 2-20mm) from a single holder. The hollow shank taper provides excellent rigidity, high repeatability and reliable automatic tool changer engagement, making it a strong choice for machining centres running HSK63F spindles.

The 70mm gauge length (70L) strikes a good balance between reach and rigidity, keeping deflection low while still clearing clamps, fixtures and part features.

Adam's tips

• Match your collet size exactly to your bit's shank diameter for the best grip and lowest runout
• Keep the HSK taper and contact face spotlessly clean — even fine dust here affects repeatability and clamping force
• Use two spanners to tighten the collet nut evenly and avoid cross-threading
• Don't overtighten — snug and secure is enough; excessive force shortens collet life
• Check runout periodically, especially after a knock, as HSK holders rely on precise contact for accuracy
