Htc 1102 Countersink 60 Degree 5 Flute Solid Carbide

Product Description

The HTC 1102 is a solid carbide countersink designed for precision holemaking in metal, wood, and composite materials. It features a 60-degree included angle and five flutes, delivering smooth, chatter-resistant cutting action on a right-hand rotation. The 3/16-inch shank diameter fits standard drill chucks and collet holders. With an overall length of 1.5 inches, this tool is well-suited for benchtop drill presses, CNC machining centers, and hand-held power drills. The bright, uncoated finish is standard for general-purpose carbide tooling. Machinists and fabricators use this countersink for deburring drilled holes and preparing fastener seats to consistent angular geometry.

This countersink is used in production machining, maintenance shops, and fabrication environments where countersunk fastener holes are required. The five-flute geometry distributes cutting load evenly, making it effective on steel, aluminum, and similar workpiece materials. The right-hand cut orientation is compatible with standard clockwise spindle rotation on virtually all drilling equipment. It is sold individually and is a direct replacement or replenishment tool for shops running C2 carbide-grade cutting tools.

Key Features

• 60-degree included angle for standard countersunk fastener seat preparation
• Five flutes for smooth, reduced-chatter cutting performance
• Solid carbide construction, C2 material grade, for durability and wear resistance
• Right-hand cut for use with standard clockwise-rotation spindles
• Bright, uncoated finish suitable for general-purpose machining applications
• 3/16-inch shank diameter fits common collet and drill chuck systems

Compatibility

Designed as a general-purpose countersink for use in standard drill chucks and collet holders accepting a 3/16-inch shank diameter, compatible with drill presses, CNC machining centers, and hand-held power drills with clockwise spindle rotation.

Installation Notes

Secure the shank firmly in the collet or drill chuck before operation. Set spindle speed appropriate for the workpiece material and tool diameter - carbide countersinks generally tolerate higher speeds than high-speed steel tools. Ensure the workpiece is clamped or fixtured to prevent movement during the countersinking operation. Inspect the cutting edges for chipping before each use, as carbide is brittle and sensitive to impact.
