Cobalt Countersink Bit 5/16 Inch Shank Diameter

Constructed with cobalt steel to improve performance when cutting harder metals, such as stainless steel or nickle alloys. Counterclockwise direction evacuates chips up and out of the cut to reduce clogging. KEO ZErO flute countersink and deburring tools are simple, all-purpose tools made of Cobalt that provide flawless countersinking and deburring. The chatter-free cutting action requires minimal power. The microsmooth CNC precision ground construction produces clean, smooth cutting without smearing on a variety of materials. The tool especially excels in countersinking or deburring holes in aluminum, plastics and other nonmetallics. Cobalt steel tools are similar to high-speed steel, but with more cobalt for improved performance when cutting harder metals such as stainless steel or nickel alloys. Round shanks allow use with a wide variety of toolholding systems.

• Cobalt steel tools are similar to high-speed steel, but with more cobalt for improved performance when cutting harder metals such as stainless steel or nickel alloys
• Uncoated tools feature just the base substrate without any additional treatment or coatings and are suitable for a wide range of applications
• Round shanks allow use with a wide variety of toolholding systems
• When run in a counterclockwise direction (right-hand cut) spiral fluted tools evacuate chips up and out of the cut to reduce clogging
• 82 degree angle
