What It Is
This Cleveland C46225 countersink is a 100-degree centre reamer made from high-speed steel with a black-oxide finish. It measures 2-5/8 inches overall and is designed to machine conical seats for flat-head fasteners in metalwork. Professional machinists and maintenance technicians use it to prepare precise countersunk holes in steel and alloy components.
Who It Suits
The tool suits workshops that regularly cut 100-degree chamfers in ferrous materials and need the wear resistance of HSS. It is not for operators who require interchangeable pilot diameters, adjustable angle settings, or carbide-grade tooling for high-volume production runs.
Deciding Specification
The fixed 100-degree included angle determines whether the reamer matches the fastener standard specified on the drawing. If the print calls for a different countersink angle, this cutter cannot produce the required seat geometry.
Highlights
- 100-degree angle produces flush fastener seats
- High-speed steel construction resists wear in repeated use

Questions about this item
Will the high-speed steel cutting edges on the C46225 need resharpening or replacement after extended use?
High-speed steel edges dull over time; resharpen or replace the countersink when hole quality drops.
What limits continuous use of the 100-degree countersink in a production environment?
Heat buildup at the cutting zone is the first limit; allow cooling intervals to maintain tool life.
Does the black-oxide finish affect heat or noise during all-day drilling?
The finish reduces friction slightly but does not change heat or noise; use cutting fluid for thermal control.
