Diamond Electroplated Fluted Countersinks

Precision Chamfering for Hard and Brittle Materials

Diamond electroplated fluted countersinks deliver precise chamfering, deburring, and seating on hard and brittle materials. Unlike carbide or HSS countersinks, diamond electroplated tools hold form accuracy and cutting aggressiveness throughout their life cycle. The fluted geometry creates a balanced cutting action that lowers cutting pressure, reduces heat, and limits micro-fracturing when entering or exiting the part.

Electroplated Bond Structure with Aggressive Cutting Action

The electroplated nickel bond exposes diamond particles at full height, which allows fast cutting speeds and clean chip evacuation. This bond structure handles materials that chip easily or store heat, such as sapphire, quartz, silicon carbide, alumina, zirconia, borosilicate glass, carbon composites, and optical substrates. Diamond fluted countersinks outperform traditional tooling when accuracy, edge quality, and yield matter.

Applications Across Advanced Industries

Manufacturers in semiconductor, aerospace, optics, precision R&D, and defense rely on diamond fluted countersinks for consistent hole seating and chamfer quality. The tools improve component yield, minimize breakout, and reduce downstream finishing or polishing.

Configurable Pilots, Shanks, and Diameters

Braemar USA produces diamond electroplated fluted countersinks with fixed or adjustable pilots, threaded shanks, straight shanks, and custom mounting configurations. Adjustable pilots improve alignment inside drilled holes and protect fragile entry and exit edges. Customers can run these countersinks on CNC equipment, manual stations, or ultrasonic spindles depending on process requirements.

Custom Options for Production or Prototype Work

Users can specify included angles, grit sizes, pilot tolerances, shank dimensions, and body diameters. Braemar USA also optimizes tools for wet cutting, dry cutting, thicker substrates, or higher feed rates in production environments.

Performance Advantages

Diamond electroplated fluted countersinks improve edge finish, reduce chipping, and enhance dimensional consistency while offering long service life on modern engineered materials.
