6-Flute High-Speed Steel Countersink, 3/4 in. Diameter, 90 Degree

This 6-flute high-speed steel countersink is designed for machinists and metalworking professionals who need to form smooth countersunk seats. Its 90-degree cutting profile helps prepare holes for flush-fitting fasteners in shop and production work.

The countersink has a 3/4-inch diameter, a 90-degree profile, and six flutes with staggered cutting angles. Its positive shearing action is designed for heavy cuts, while the cutting load is shared across six cutting edges. It can be used with milling machines, drill presses, screw machines, lathes, automatics, special machines, feed units, and hand tools. Effective minimum order: 1 each.

Key Features:

• Six-flute design: Distributes cutting load across multiple cutting edges for extended tool service life.
• Staggered cutting angles: Helps reduce harmonics associated with chatter during countersinking.
• Positive shearing action: Supports heavy cutting work and smooth countersunk seats.
• 90-degree profile: Creates a standard angled seat for compatible countersunk fasteners.

Choose this countersink for metalworking operations that require a 3/4-inch, 90-degree countersink with a six-flute cutting design and broad machine-tool compatibility.
