Htc 1105 Countersink 60 Degree 7 Flute Solid Carbide

Product Description

The HTC 1105 is a solid carbide countersink designed for precision hole finishing in metalworking and fabrication applications. Built with 7 flutes and a 60-degree included angle, it produces clean, chatter-free chamfers on drilled holes. The 3/8-inch shank diameter fits standard drill chucks and collet holders, and the 2-inch overall length suits most bench drill press and CNC machining center setups. The bright, uncoated finish is suited for general-purpose cutting, and the C2 carbide material grade delivers hardness and wear resistance for ferrous and non-ferrous materials. Licensed machinists, tool and die workers, and CNC operators are the primary users of this tool.

This countersink is used in machine shops, fabrication facilities, and production environments where consistent chamfer geometry is required. It is well suited for deburring and countersinking holes ahead of fastener installation in steel, aluminum, brass, and similar materials. The right-hand cut orientation is compatible with standard clockwise spindle rotation on drill presses, mills, and machining centers. It is cataloged under industrial holemaking tooling and is sold individually.

Key Features

• 7 flutes reduce chatter and improve surface finish quality
• Solid carbide construction with C2 material grade for hardness and wear resistance
• Right-hand cut for use with standard clockwise spindle rotation
• 3/8-inch shank diameter fits common collet and drill chuck systems
• Bright, uncoated finish for general-purpose cutting applications

Compatibility

Designed as a general-purpose countersink for use in drill presses, manual mills, and CNC machining centers accepting a 3/8-inch round shank toolholder or collet.

Installation Notes

Installation and use of this tool should be performed by qualified machinists or tooling technicians. Ensure the spindle is fully stopped and the machine is powered down before inserting or removing the tool from the holder. Secure the shank firmly in a collet or drill chuck rated for the shank diameter before operation. Follow applicable shop safety standards and machine tool manufacturer guidelines for speed and feed selection.
