Titan Usa CS36916 Countersink 1/4 in 100 Deg 6 Flute

Product Description

The TITAN USA CS36916 is a single-flute countersink designed for creating precise chamfered seat profiles in metal, wood, and composite materials. With a 1/4 inch head diameter, a 100-degree included angle, and six flutes, this tool delivers clean, chatter-resistant cuts in a compact form factor. The 1/4 inch shank diameter fits standard drill chucks and quick-change collet systems, and the 2 inch overall length (OAL) keeps the tool manageable in tight-clearance applications. Machinists, tool-and-die technicians, and fabricators use this countersink for deburring drilled holes and seating fastener heads flush with or below a workpiece surface.

This countersink is suited for light-duty to medium-duty countersinking tasks on the bench, in a drill press, or in a CNC machining center. The 100-degree included angle accommodates flat-head fasteners with that angle specification, which appear in aerospace, general metalworking, and woodworking applications. The 1/4 inch shank makes it compatible with most standard drill chucks and collet-style quick-change systems found in trade shops and field fabrication setups. It ships as a single unit.

Key Features

• 1/4 inch head diameter for small-fastener countersink seats
• 100-degree included angle matches flat-head screw specifications requiring that geometry
• 6-flute design reduces chatter and produces a cleaner finish than single-flute tools
• 1/4 inch shank diameter fits standard drill chucks and quick-change collet holders
• 2 inch overall length for use in drill presses, hand drills, and CNC setups

Compatibility

Designed as an OEM-style replacement or direct-use countersink for applications requiring a 1/4 inch head diameter, 100-degree included angle, 6-flute tool with a 1/4 inch shank.

Installation Notes

Install in a drill press, hand drill, or CNC spindle using a standard 1/4 inch collet or drill chuck. Secure the shank fully before operation and confirm the spindle is at a full stop before changing tools. Use appropriate cutting speed for the workpiece material and apply cutting fluid when countersinking hardened or stainless steel to extend tool life. Eye protection is required during all machining operations.
