Crown Tools quick-release handles have been developed over several years to provide a better grip and enhanced functionality. These innovative handles feature self-ejecting heads, making blade changes quick and effortless. The collet is securely encapsulated in the head, so when you untwist it, the collet releases smoothly, allowing the blade to loosen with ease. Each handle includes three different size heads to suit various needs: Small (10mm, Gold), Medium (13.2mm, Blue), and Large (16.2mm, Red). This design ensures versatility and convenience for a range of applications. Model Number:
