Each pattern in the series uses a mono-beveled cutting edge, but differs intentionally in bevel length and angle of attack — producing distinct cutting behavior suited to different surgical objectives.\u003c\/p\u003e\u003cp\u003eThe CKN3 is the primary extraction-adjacent instrument in this series. Its long bevel and gentle angle of attack allow progressive bone widening and splitting, making it well suited for creating access around impacted or ankylosed teeth where controlled expansion of the surgical site is required.\u003c\/p\u003e\u003cp\u003eThe CKN55 and CKN75 feature shorter bevels with a steeper, more acute angle of attack. This geometry concentrates force at the cutting edge for more aggressive bone engagement — useful for removing dense cortical bone, exostoses, and tori that obstruct surgical access or complicate extraction site management.\u003c\/p\u003e\u003cp\u003eManufactured by Hu-Friedy from surgical-grade stainless steel for durability, corrosion resistance, and consistent clinical performance.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eAvailable Variants\u003c\/strong\u003e\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eCKN3\u003c\/strong\u003e — 7.5 mm mono-bevel working end.
