Htc 1108 Countersink 60 Degree 9 Flute Solid Carbide

Product Description

The HTC 1108 is a solid carbide countersink designed for precision holemaking in metalworking and machining applications. It features a 60-degree included angle and 9 flutes, delivering smooth, chatter-resistant cutting action on a wide range of materials. The bright, uncoated finish is suited to general-purpose use, and the right-hand cutting direction is compatible with standard spindle rotation. With a 0.5-inch shank diameter and an overall length of 2.5 inches, this countersink fits conventional drill presses, CNC machining centers, and manual mills without adapters.

This countersink is used in production and job-shop environments where consistent, clean countersunk holes are required for flat-head fasteners, deburring operations, or chamfering. It is appropriate for use on steel, cast iron, aluminum, and other materials within the C2 carbide grade range. Machinists, tool-and-die makers, and CNC operators working in fabrication, aerospace prep, or general metal shops are the typical end users for this tool.

Key Features

• 60-degree included angle for standard flat-head fastener countersinking
• 9 flutes provide smooth cutting action and reduce chatter
• Solid carbide construction for rigidity and wear resistance
• C2 carbide grade suitable for general-purpose machining on ferrous and non-ferrous materials
• Bright, uncoated finish - no coating to chip or peel in service
• Right-hand cut compatible with standard clockwise spindle rotation

Compatibility

Designed as a standard-shank countersink for use in drill presses, CNC machining centers, and manual milling machines accepting a 0.5-inch round shank. No specific OEM compatibility was stated in the product data.

Installation Notes

Secure the shank firmly in a drill chuck or collet before operation and verify runout is within acceptable tolerance for the application. Set spindle speed according to the workpiece material and tool diameter - carbide tooling generally runs at higher speeds than high-speed steel but requires stable setups to avoid breakage. Always wear appropriate eye protection, and inspect the tool for edge chipping or cracks before each use. Carbide is brittle; avoid dropping or side-loading the tool.
