High-Speed Steel 6-Flute 3/8-Inch 90-Degree Countersink

This 3/8-inch countersink is designed for machinists and metalworking professionals who need to create smooth countersunk seats. Its six-flute design supports use in a range of machine and hand-tool operations.

The high-speed steel countersink has a 3/8-inch diameter and a 90-degree cutting angle. Six flutes use staggered cutting angles and a positive shearing action, with cutting load distributed across six cutting edges. It is suitable for milling machines, drill presses, screw machines, lathes, automatics, special machines, feed units, and hand tools.

Key Features:

• Six-Flute Design: Distributes cutting load across six cutting edges to support long service life.
• Staggered Cutting Angles: Helps reduce the harmonics associated with chatter in conventional tools.
• Positive Shearing Action: Supports heavy cuts and smooth countersunk seats.
• 90-Degree Angle: Provides a defined countersink profile for compatible applications.
• Effective Minimum Order: Minimum order quantity is 1.

Choose this 3/8-inch, 90-degree countersink for metalworking tasks that call for a six-flute cutting tool with chatter-reducing geometry and smooth-seat performance.
