Precision Twist Drill 097604 Hss Combo Drill Countersink

Product Description

The PRECISION TWIST DRILL 097604 is a combination high-speed steel (HSS) drill and countersink in a stub-length configuration. This tool performs two operations in a single pass: drilling a pilot hole and countersinking in one step, reducing tool changes and setup time on the job. The stub-length body provides added rigidity for accurate hole placement, and the 1-inch cutting depth handles typical fastener countersink applications in metal, wood, and composite materials. Licensed tradespeople and experienced machinists working in fabrication, HVAC panel work, electrical enclosures, and general mechanical assembly will find this a practical single-tool solution.

This combo drill and countersink is suited for use in residential and commercial trade applications where countersunk fastener seats are required. Typical scenarios include sheet metal work, control panel fabrication, ductwork framing, and structural assembly tasks that call for flush or recessed fastener heads. The stub-length design makes it especially practical in tight clearance situations where a full-length bit would be difficult to maneuver.

Key Features

• Combines drilling and countersinking in a single tool pass
• High-speed steel (HSS) construction for durability in metal and multi-material applications
• Stub-length body provides increased rigidity and improved hole accuracy
• 1-inch cutting depth suitable for standard fastener countersink applications
• Sold individually (minimum order quantity: 1)

Compatibility

Designed as an OEM-style replacement or direct-use combo drill for standard drill chucks accepting stub-length shank tooling in trade and light industrial applications.

Installation Notes

This tool is installed into a standard keyed or keyless drill chuck by hand-tightening or chuck key to secure the shank before operation. Ensure the workpiece is firmly clamped before drilling to prevent walking or chatter. Use appropriate cutting fluid when drilling ferrous metals to extend tool life. Always wear eye protection and follow applicable OSHA safety standards when operating rotary cutting tools.
