Htc 1103 Countersink 60 Degree 5 Flute Solid Carbide

Product Description

The HTC 1103 is a solid carbide countersink designed for precision hole finishing in metalworking and machining applications. It features a 60-degree included angle and five flutes for smooth, chatter-resistant cutting action. The right-hand cut geometry suits standard CNC and manual drilling setups. With a 1/4-inch shank diameter and a 2-inch overall length, this tool fits a wide range of drill chucks, collets, and quick-change toolholders. The bright, uncoated finish is standard for general-purpose carbide tooling. Machinists and tool and die professionals rely on this countersink for deburring, chamfering, and seat preparation in ferrous and non-ferrous materials.

The HTC 1103 is suited for shop floor and production use where consistent countersink geometry is required. It is appropriate for chamfering drilled holes, preparing fastener seats, and deburring workpiece edges in both light and heavy machining environments. The 60-degree angle is commonly used for countersinking flat-head fastener seats and chamfering in aerospace and general metalworking applications. This tool is intended for use by machinists, tool and die makers, and maintenance technicians working with lathes, mills, or drill presses.

Key Features

• 60-degree included angle for standard flat-head fastener seat preparation and chamfering
• 5-flute design reduces chatter and produces a smoother finish than single- or double-flute tools
• Solid carbide construction provides hardness and wear resistance for extended tool life
• Right-hand cut geometry compatible with standard spindle rotation
• 1/4-inch shank diameter fits common collets, chucks, and quick-change holders
• Bright, uncoated finish - no coating interference on close-tolerance applications

Compatibility

Designed as a general-purpose solid carbide countersink for use in drill presses, milling machines, and CNC machining centers accepting a 1/4-inch shank.

Installation Notes

Install this countersink in a properly sized collet or drill chuck and confirm secure clamping before operation. Power down and lock out the machine before changing tooling per standard OSHA lockout/tagout procedures. Use appropriate cutting fluid or dry cutting practices consistent with the workpiece material. Inspect the cutting edges for chipping before each use, as carbide tools can fracture if subjected to interrupted cuts or excessive side loading.
