Precision Twist Drill 097605 Hss Combo Drill Countersink

Product Description

The PRECISION TWIST DRILL 097605 is a combination high-speed steel (HSS) drill and countersink in a stub-length configuration, built for trade and production drilling applications where a clean, countersunk hole is needed in a single pass. With 1 inch of cutting depth, this tool removes the need for a separate countersinking step, saving setup time on repetitive fastener-prep work. HSS construction provides the hardness and heat resistance required for drilling into steel, aluminum, and other common metals encountered in HVAC, plumbing, and general mechanical work.

This combo drill-countersink is suited for technicians and fabricators who need to prep holes for flat-head fasteners in sheet metal, structural brackets, or light plate stock. The stub-length body offers added rigidity compared to jobber-length drills, reducing deflection when drilling without a guide bushing. It is a practical choice for field service work and shop production alike, particularly in applications where countersinking by hand or with a separate tool is time-consuming.

Key Features

• Combination drill and countersink in one tool — single-pass hole prep for flat-head fasteners
• High-speed steel (HSS) construction for durability in metal drilling applications
• Stub-length body increases rigidity and reduces bit deflection
• 1 inch cutting depth suits typical sheet metal and light plate fastener work
• Compact design compatible with standard drill chucks

Compatibility

Designed as an OEM-style special-purpose combination drill for use in standard drill presses, hand drills, and screw machines accepting stub-length tooling with a compatible shank diameter.

Installation Notes

This tool is installed and used by machinists, fabricators, and trade technicians working with drill presses or hand-held power drills. Secure the workpiece firmly before drilling to prevent movement and ensure a clean countersink. Use appropriate cutting fluid for metal applications to extend tool life and improve hole quality. Always wear eye protection and follow applicable shop safety practices when operating rotary cutting tools.
