17/64 190-AG Jobber Drill Bit

• Manufactured to NAS 907B specification from Premium Hi-molybdenum steel.
• Substantially outperforms cobalt drill bits in stainless steel, hardened steel and other heavy-duty drilling applications.
• Nitrocarburized for toughness, decreased wear, and corrosion resistance.
• Withstands substantially higher drilling temperatures while maintaining sharpness.
• UPC 050728057107

Magnum drill bits use special Hi-Molybdenum tool steel and feature a 135° split point for fast penetration and accurate starting without a center punch. They withstand substantially higher drilling temperatures while maintaining sharpness. Body and clearance are gold surface treated for maximum lubricity. These rill bits are heat treated at 2185° F and then nitrocarburized at 950° to be measurably harder than high-speed steel.
