Titan Usa CD51526 Countersink 90 Degree 1 Flute Hss

Product Description

The TITAN USA CD51526 is a single-flute countersink designed for creating clean, chamfered seat holes in metal workpieces ahead of fastener installation. Built from high speed steel (HSS) with a bright, uncoated finish, this tool delivers reliable cutting performance across a range of shop and field applications. The 90-degree included angle is the standard geometry for flathead fastener seating in most machined metal assemblies. The straight cylindrical shank mounts directly into standard drill chucks and countersink holders without adapters. Machinists, toolmakers, and maintenance mechanics working with metal fabrication and assembly operations will find this a straightforward, no-frills countersinking solution.

This countersink is suited for light-duty countersinking tasks in ferrous and non-ferrous metals where a 90-degree seat angle is specified. The single-flute design reduces chatter and produces a smooth finish in the chamfer. Typical applications include deburring drilled holes, preparing fastener seats in steel plate, aluminum, and similar materials, and touch-up work on machined components. It is particularly useful in situations where a simple, low-maintenance tool is preferred over coated or multi-flute alternatives.

Key Features

• 90-degree included angle matches standard flathead fastener geometry
• Single-flute design minimizes chatter for a cleaner chamfer finish
• High speed steel construction provides durable cutting performance on common metals
• Bright uncoated finish allows visual wear inspection during service life
• Straight cylindrical shank fits standard drill chucks and countersink holders

Compatibility

Designed as a general-purpose countersink for use in standard drill chucks and compatible countersink holders accepting a straight cylindrical shank.

Installation Notes

Installation is performed by machinists or maintenance technicians using a drill press, milling machine, or hand drill with appropriate speed settings for the workpiece material. Secure the straight shank firmly in the chuck before operation to prevent runout. Always reduce spindle speed when countersinking harder materials to extend tool life and improve finish quality. Wear appropriate eye protection and ensure the workpiece is clamped securely before initiating the cut.
