Description

IVY Classic 04007 7/64-Inch Cobalt Steel Jobber Length Drill Bit 12-Pack

The IVY Classic 04007 7/64-Inch Cobalt Steel Drill Bit 12-Pack delivers rapid penetration and extreme heat resistance when boring into high-tensile alloys, cast iron, and stainless steel. Manufactured from precision-ground cobalt alloy steel with a friction-reducing gold finish, each jobber length bit incorporates a 135-degree split point tip that self-centers instantly to prevent bit wander on curved metal stock. This contractor-grade multi-pack provides consistent dimensional accuracy across repetitive production drilling, metal fabrication, and maintenance operations.

Best Used For:

  • Stainless Steel & Alloy Machining: Drilling precision pilot holes in hardened stainless steel sheet, chrome alloys, and titanium plates without edge dulling.
  • Automotive & Machine Fabrication: Boring through tough cast iron engine brackets, structural angle iron, and high-carbon metal assemblies.
  • Hardware Pre-Drilling: Creating accurate fastener clearance holes in dense hardwoods, composites, and structural plastics.

Key Performance & Safety Features

  • Cobalt Alloy Steel Metallurgy: Retains core hardness and cutting edge integrity under the extreme frictional temperatures generated by difficult-to-machine alloys.
  • 135-Degree Split Point: Self-centering tip layout bites immediately into flat and rounded surfaces to eliminate walking without requiring a center punch.
  • Gold Oxide Finish: Precision-ground surface treatment improves chip lubricity and dissipates heat during high-speed feed rates.
  • Jobber Length Flutes: Balanced 2-5/8-inch overall length delivers optimal rigidity to resist torsional flex and breakage under heavy drill press load.
  • Swift Bore Design: Parabolic flute engineering clears metal swarf rapidly from the hole cavity to prevent chip binding.
