The 135° split point is self-centering for accurate starting without a center punch. Meant for faster, easier penetration and reduced thrust. Manufactured from premium high-speed steel and a heavy-duty construction for drilling in tougher materials. Titanium nitride (TiN) provides a super hard surface with high lubricity. Which greatly extends tool life in high wear or very abrasive applications. Manufactured to NAS 907B aerospace specification, Type 190-AN. Made in USA.
Titanium nitride (TiN) coating adds lubricity and hardness, enhancing chip flow, finish hole quality and drill life.
