IVY Classic Drill Bit Set 04030 15/32 Inch Cobalt Steel 6 Pack (135 Degree Split Point 3/8 Inch Reduced Shank Stainless Hard Metal Boring Tool)

IVY Classic 04030 15/32-Inch Cobalt Steel Reduced Shank Drill Bit 6-Pack

The IVY Classic 04030 15/32-Inch Cobalt Steel Drill Bit 6-Pack delivers high-speed penetration and severe thermal resistance when boring into work-hardening stainless steel, cast iron, and high-tensile structural alloys. Manufactured from premium cobalt alloy high-speed steel with a heat-resistant gold surface finish, each jobber length bit incorporates a 135-degree split point that self-centers instantly upon contact to eliminate bit walking without requiring a center punch. The engineered 3/8-inch reduced shank enables these large-diameter 15/32-inch cutters to chuck securely into standard 3/8-inch and 1/2-inch portable drills and stationary drill presses.

Best Used For:

• Stainless Steel & Alloy Machining: Drilling precision through-holes and tap clearances in 304/316 stainless plate and marine grade hardware without edge glazing.
• Heavy Equipment Fabrication: Boring structural fastener holes through cast iron housings, carbon steel truck chassis rails, and thick weldments.
• General Metal Fabrication: Enlarging pre-drilled holes in structural steel tubing, titanium sheet, and high-strength alloy brackets using standard handheld drills.

Key Performance & Safety Features

• Cobalt Alloy Tool Steel: High-density cobalt-infused metallurgy maintains red hardness and edge sharpness under severe frictional temperatures.
• 135-Degree Split Point: Self-centering tip architecture bites immediately into curved pipe or flat plate surfaces to eliminate drill wandering.
• 3/8-Inch Reduced Shank: Fits standard 3/8-inch drill chucks, expanding the boring capacity of compact handheld drills without requiring heavy tooling.
• Precision Ground Flutes: Parabolic flute geometry evacuates hot metal swarf quickly from the cut zone to prevent chip packing and binding.
• Contractor 6-Pack Supply: Provides immediate backup tooling on the production floor or jobsite to eliminate unexpected operational downtime.

Technical Specifications

Pro-Tip: When boring through thick stainless steel with a 15/32-inch bit, run your drill at low rotational RPM with continuous downward pressure and apply cutting fluid; never ease up on feed pressure while the bit is spinning to prevent work-hardening the metal base.
