KEO Countersink: 100°, 3 Flute, 1 1/4 in Body Dia

The KEO 100° countersink is used for deburring and countersinking holes in metal workpieces, particularly in aerospace and general machining applications. Its 100° included angle and three-flute design provide smooth cutting and chip evacuation. The AlTiN-coated cobalt construction enhances wear resistance and extends tool life when machining hardened steels and stainless alloys.

The KEO 917-000-865 is a general-purpose three-flute countersink with a 100° included angle and a 1 1/4 in body diameter. It features an AlTiN coating on cobalt substrate for heat resistance and durability. The tool is designed for use in CNC and manual machines, producing clean, burr-free countersinks in ferrous and non-ferrous materials.

KEO countersinks are available to order through 3G Electric, a global industrial equipment distributor. We source and deliver KEO cutting tools to worldwide destinations, handling full logistics and customs clearance. Contact 3G Electric for pricing and lead time on the KEO 917-000-865 or other KEO countersink models.

Select a KEO countersink based on the required countersink angle (e.g., 100° for flat-head screws), material hardness, and hole size. For hardened steels, choose AlTiN-coated cobalt tools like the 917-000-865. Match the body diameter to the countersink depth needed. Always use proper speeds and feeds per the manufacturer's recommendations for optimal tool life.
