IVY Classic Drill Bits 04032 1/2 Inch Swift Bore Cobalt 6 Pack (135 Degree Split Point 3/8 Inch Reduced Shank Stainless Steel Metal Boring Tool)

IVY Classic Swift Bore 04032 1/2-Inch Cobalt Steel Reduced Shank Drill Bit 6-Pack

The IVY Classic 04032 1/2-Inch Swift Bore Cobalt Steel Drill Bit 6-Pack provides severe thermal resistance and high-speed penetration when boring into work-hardening stainless steel, cast iron, titanium, and high-tensile structural alloys. Engineered from premium cobalt alloy high-speed steel with a heat-dissipating gold surface finish, each 6-inch jobber length bit features a 135-degree split point that self-centers instantly on contact to eliminate drill walking without center punching. The 3/8-inch reduced shank enables these large 1/2-inch cutters to chuck securely into standard 3/8-inch and 1/2-inch portable drills and stationary drill presses for structural fabrication, machine overhaul, and jobsite maintenance.

Best Used For:

• Stainless Steel & Alloy Machining: Drilling precision 1/2-inch bolt clearance holes and tap entries in 304/316 stainless plate and marine hardware without edge glazing.
• Structural Steel & Frame Fabrication: Boring fastener pass-throughs through thick cast iron machinery housings, structural truck chassis rails, and heavy weldments.
• General Industrial Metalworking: Drilling high-tensile carbon steel plate, bronze bushings, and hard composites using portable handheld drills with 3/8-inch chucks.

Key Performance & Safety Features

• Cobalt Alloy Tool Steel: High-density cobalt-infused metallurgy retains red hardness and sharp cutting edges under severe frictional heat and continuous drilling loads.
• 135-Degree Split Point: Self-centering tip architecture bites immediately into curved pipe or flat metal surfaces to eliminate drill wandering and reduce thrust requirements.
• 3/8-Inch Reduced Shank: Fits standard 3/8-inch drill chucks, expanding the drilling capacity of compact handheld drills without requiring heavy industrial machinery.
• Precision-Ground Gold Finish: Specialized surface treatment improves lubricity, reduces chip friction, and protects cutting margins against thermal burnout.
• Jobber Length Flute Geometry: Rigid 6-inch body profile balances deep hole reach with maximum torsional deflection resistance during heavy downward feed pressure.

Technical Specifications

Pro-Tip: Maintain a slow rotational speed and apply heavy, continuous feed pressure paired with cutting lubricant when drilling stainless steel; preventing bit chatter protects the 135-degree split point from work-hardening the metal surface.
