Precision Twist Drill 097602 Hss Combo Drill Countersink

Product Description

The PRECISION TWIST DRILL 097602 is a combination high-speed steel (HSS) drill and countersink designed for stub-length drilling applications. It delivers a 1 inch cutting depth, making it well suited for controlled, close-tolerance work where a standard-length bit would be impractical. The stub-length body provides added rigidity, reducing deflection and chatter during operation. This tool performs both drilling and countersinking in a single pass, saving setup time on production runs or repetitive fastener-prep work. It is a special-purpose bit intended for trade and industrial users who need consistent, repeatable results in metal or similar materials.

This combo drill and countersink is appropriate for metalworking applications where fastener seats must be prepared accurately. Its stub-length design suits drill presses, CNC setups, and benchtop operations where shorter tool projection is an advantage. Machinists, maintenance technicians, and fabricators working with screw or bolt assemblies will find this tool useful for countersinking pilot holes in a single operation without tool changes.

Key Features

• Combination drill and countersink in one tool — eliminates a tool-change step
• High-speed steel (HSS) construction for durability in metal drilling applications
• Stub-length body provides increased rigidity and reduced deflection
• 1 inch cutting depth for controlled, close-tolerance work
• Sold individually (minimum order quantity: 1)

Compatibility

Designed as an OEM-style special-purpose HSS combo drill and countersink suitable for use in standard drill chucks compatible with stub-length shank tooling.

Installation Notes

This tool is installed and operated by machinists or maintenance technicians using a drill press, milling machine, or compatible power tool with an appropriately sized chuck. Secure the workpiece firmly before operation to prevent movement during drilling and countersinking. Ensure the spindle speed is appropriate for the material being drilled and the tool diameter per standard machining practice. Inspect the cutting edges before use and replace the tool if chipping or excessive wear is observed.
