Viking Ultra-Bor Series Type 240-UB Super Premium HSS Jobber length Letter Size drill bits excel in demanding applications. The 135° split point design is self-centering and self-starting, preventing the drill bit from walking on the material surface and eliminating the need for a center punch or pilot hole. Black and Gold surface treatment provides additional lubricity, reduces wear and assists swarf in traveling along the flutes with less resistance as it exits the hole during drilling. Made in America using high moly alloy tool steel, the heavy-duty construction of Type 240-UB Super Premium Number Drill Bits makes them ideal for use with hard metals, work hardening grades of stainless steel, and other difficult to drill materials.
