Precision Twist Drill 4710801 Countersink 3/4 in 80 Deg

Product Description

The PRECISION TWIST DRILL 4710801 is a single flute, straight shank countersink designed for precise hole finishing in metal, wood, and composite materials. Built with an 80-degree included angle, this countersink deburrs and chamfers drilled holes cleanly with minimal chatter. The 3/4 inch tip diameter and overall length of approximately 2-13/32 inches make it a compact, easy-handling tool suited for bench drill presses and hand-held power drills alike. Machinists, pipefitters, and general fabrication trades reach for this style of countersink when a clean, consistent seat is required before fastener installation.

This countersink is well suited for light industrial and general trade applications where a single flute design is preferred for its self-centering characteristics and smooth cutting action. It works effectively on ferrous and non-ferrous metals as well as softer materials. The straight shank seats directly into standard drill chucks without adapters, making it a quick-change option in production or field environments where efficiency matters.

Key Features

• Single flute geometry minimizes chatter and produces a smooth countersink finish

Compatibility

Designed as an OEM-style replacement or direct-use countersink for standard drill chucks accepting straight shank tooling across bench drill presses and handheld power drill applications.

Installation Notes

Installation and use should be performed by a qualified machinist or experienced tradesperson familiar with rotating cutting tools. Always secure the workpiece firmly before engaging the tool, and ensure the drill chuck is tightened completely before operation. Run at appropriate speeds for the material being countersunk — slower speeds are recommended for harder metals to prevent premature tool wear. Wear appropriate eye protection whenever operating rotary cutting tools.
