Precision Twist Drill 097603 Hss Combo Drill Countersink

Product Description

The PRECISION TWIST DRILL 097603 is a combination high-speed steel (HSS) drill and countersink designed for trade and industrial applications where drilling and countersinking are performed in a single pass. Built to stub length, this tool offers a 1-inch cutting depth, keeping the bit rigid and reducing chatter during operation. Licensed trades and production shops alike use combination tools like this to cut steps out of their workflow when setting fasteners flush or preparing material for flathead hardware. The HSS construction holds up to repeated use across a range of ferrous and non-ferrous materials.

This combo drill and countersink is suited for use in metalworking, HVAC sheet metal fabrication, electrical enclosure work, and general trade shop applications. The stub-length body keeps deflection low, making it a practical choice in drill presses or hand drills where precision entry angles matter. Its compact form is useful in tight clearances where a jobber-length bit would be impractical.

Key Features

• Combination drill and countersink in a single tool — drills and countersinks in one pass
• Stub length body reduces deflection and improves rigidity during use
• 1-inch cutting depth suitable for sheet metal and light stock
• High-speed steel (HSS) construction for durability across ferrous and non-ferrous materials
• Minimum order quantity of 1 — available as a single unit

Compatibility

Designed as an OEM-style replacement or direct-use combination drill-countersink for standard drill chucks in drill press and hand drill applications where stub-length HSS bits are specified.

Installation Notes

This tool is installed into a standard drill chuck by a machinist, fabricator, or licensed trade professional. Secure the bit fully in the chuck before operation and confirm the workpiece is clamped or fixtured to prevent movement. Always wear appropriate eye protection when drilling or countersinking metal stock. Inspect the cutting edges before each use and replace if chipping or wear is evident.
