Htc 1107 Countersink 60 Degree 7 Flute Solid Carbide

Product Description

The HTC 1107 is a solid carbide countersink designed for precision chamfering and deburring of drilled holes in metalworking and fabrication applications. Built with 7 flutes and a 60-degree included angle, it delivers smooth, chatter-resistant cutting action on a variety of workpiece materials. The 1/2-inch shank diameter fits standard drill chucks and collet holders, and the 2-inch overall length provides adequate reach for most bench and CNC drilling setups. The bright, uncoated finish maintains dimensional accuracy on the cutting edges. This tool is specified for right-hand cutting rotation. It is suited for machinists, tool and die shops, and production environments requiring consistent, repeatable countersink geometry.

The HTC 1107 is used in holemaking operations where fastener seats, chamfers, or deburring of hole edges are required. Typical applications include countersinking for flat-head fasteners in steel, aluminum, brass, and similar materials. The C2 carbide grade provides durability across general-purpose metal cutting tasks. This tool fits standard 1/2-inch collet and chuck setups on drill presses, milling machines, and CNC machining centers running right-hand spindle rotation.

Key Features

• 60-degree included angle for standard fastener countersink geometry
• 7 flutes for reduced chatter and smoother surface finish in the countersunk area
• Solid carbide construction, C2 grade, for extended tool life versus high-speed steel alternatives
• Bright, uncoated finish maintains sharp edge geometry out of the box
• Right-hand cut for use with standard clockwise spindle rotation
• 1/2-inch shank diameter fits common collet and drill chuck toolholding systems

Compatibility

Designed for use in drill presses, milling machines, and CNC machining centers with a 1/2-inch collet or drill chuck and right-hand spindle rotation. Suitable for general-purpose countersinking in ferrous and non-ferrous metals.

Installation Notes

Secure the 1/2-inch shank firmly in a collet or drill chuck before operation and verify spindle rotation is set to right-hand before engaging the workpiece. Ensure the workpiece is clamped securely to prevent movement during the countersinking operation. Use appropriate cutting speed and feed rate for the workpiece material and consult the tool manufacturer or machining reference data for recommended parameters. Inspect cutting edges for wear or chipping before each use.
