Plow Through Hardened Stainless Steel and Abrasive Alloys with Premium Cobalt Thermal Endurance

Defeat the most stubborn workpieces and maximize your workshop production rates with the industrial strength of the Ivy Classic Cobalt Drill Bit 12-Pack. Purpose-built for professional metal fabricators, machinists, auto mechanics, and commercial maintenance crews, these heavy-duty jobber length twist bits handle punishing cutting cycles that destroy standard high-speed steel (HSS) bits. Forged from premium cobalt steel alloy, this collection maintains absolute structural hardness even when subjected to the extreme thermal spikes generated by hard-to-machine metals. Whether you are repeatedly drilling out broken fasteners or boring deep installation paths, these gold-finished bits cut cleanly through tough stainless steel, high-tensile iron alloys, titanium sheets, natural hardwoods, and dense industrial plastics.

Uncompromising tracking speed and a massive increase in field service life define the technical design of this bulk fleet package. Every bit features a precision-ground 135-degree split point cutting head that automatically forces a fast, self-centering material bite. This aggressive tip design completely eliminates annoying bit walking or surface skidding upon initial contact, cutting out the mandatory step of center-punching layout marks and saving valuable runtime on your cordless handheld drills. Complemented by precision-engineered parabolic flutes that instantly clear packing metal curls and abrasive chips away from the cutting zone, these heavy-duty bits minimize frictional binding and work-hardening to deliver flat, uniform holes from start to finish.

Key Features

• Premium Cobalt Steel Build: Rugged metallurgical matrix retains core structural hardness and resists abrasive wear at extreme operating temperatures.
• 135-Degree Split Point Tip: Self-centering cutting geometry bites instantly into metal surfaces to eliminate skidding, bit walking, and surface marring.
• Precision-Ground Gold Finish: Polished exterior finish lowers operational friction and ensures highly accurate, round holes with smooth sidewalls.
• High-Velocity Chip Evacuation: Advanced spiral flute channels quickly lift hot metal debris away from the cutting zone to prevent binding and tool stall.
• Multi-Material Versatility: Masterfully engineered to cut stainless steel, high-carbon alloys, cast iron, structural aluminum, woods, and rigid plastics.
• Contractor-Focused 12-Pack Bulk Case: High-volume shop package ensures your crew always has fresh, razor-sharp boring tools ready on the deck.

Specifications

Pro-Tip: When drilling into dense structural stainless steel or hardened alloys with cobalt bits, heat management and rotational speed are critical to preventing your workpiece from work-hardening. Always drop your drill's operating speed to a low RPM and apply heavy, steady downward mechanical pressure to force the 135-degree split point to constantly slice fresh metal. Apply a few drops of specialized cutting fluid or heavy motor oil directly to the target drilling point; this cooling barrier lowers friction, protects the gold-finished cutting edges, and significantly extends the lifespan of your bits.
