Precision Twist Drill 6002230 Spotting Drill 3/8 in

Product Description

The PRECISION TWIST DRILL 6002230 is a solid carbide spotting drill designed to create accurate center points and chamfered entry holes for twist drills, reamers, and other rotary cutting tools. With a 90-degree point angle and a 3/8-inch cutting diameter, this tool establishes precise hole location before full drilling operations begin. The bright, uncoated solid carbide construction delivers good rigidity and edge retention across a range of workpiece materials. Overall length is 3 inches, with a 1-inch flute length and a 3/8-inch straight cylindrical shank. It is used by machinists, tool-and-die professionals, and maintenance technicians in production and job-shop environments.

This spotting drill is suited for general-purpose spotting and center-marking operations on machining centers, CNC mills, drill presses, and manual milling machines. The right-hand cut, two-flute spiral configuration supports chip evacuation and consistent entry geometry. The DS-90 series is intended for applications where accurate hole positioning and clean chamfer profiles are required before secondary drilling or reaming passes.

Compatibility

Designed as a general-purpose spotting drill for use in standard straight-shank toolholders and collet chucks accepting a 3/8-inch shank diameter on CNC and manual machining equipment.

Installation Notes

Installation and use should be performed by qualified machinists or tooling technicians. Secure the shank fully in a collet, end-mill holder, or drill chuck rated for the 3/8-inch shank diameter before beginning any operation. Ensure the spindle is at a complete stop and machine power is off before changing or inspecting tooling. Follow applicable machine tool manufacturer guidelines and shop safety protocols when setting speeds and feeds for carbide tooling.
