Precision Twist Drill 4710802 Countersink 1 in 80 Degree

Product Description

The PRECISION TWIST DRILL 4710802 is a single-flute, straight-shank countersink designed for creating clean, chamfered entry holes in metal and similar materials. The tool features an 80-degree included angle and a 1-inch tip diameter, making it suited for deburring, chamfering, and countersinking fastener seats in production and maintenance applications. At 0.25 pounds, it is a compact, lightweight tool. Licensed tradespeople and skilled machinists working on metal fabrication, HVAC equipment assembly, or mechanical maintenance will find this countersink well-matched to bench drill press and handheld drill driver setups.

This countersink is appropriate for use in light manufacturing, sheet metal work, and field service applications where a consistent 80-degree chamfer is required. The straight shank allows direct chucking in standard drill presses, CNC machines, or handheld power drills without an adapter. Overall tool length is 2-13/16 inches, keeping the tool rigid and minimizing chatter during operation. It is sold individually as a single unit.

Installation Notes

Installation is performed by machinists, sheet metal workers, or maintenance technicians using a standard keyed or keyless drill chuck. Secure the straight shank firmly in the chuck before operation and confirm the workpiece is clamped or fixtured to prevent movement. Apply consistent, moderate feed pressure to avoid work hardening or tool deflection. Always wear appropriate eye protection when operating rotary cutting tools.
