Precision Twist Drill 6000060 Spotting Drill 3/8 in Tin Hss

Product Description

The PRECISION TWIST DRILL 6000060 is a 90-degree spotting drill designed to create accurate center points and guide holes for follow-up drilling operations. Manufactured from high speed steel (HSS) with a titanium nitride (TiN) coating, it delivers extended tool life and reduced friction at the cutting edge. The drill measures 5 inches in overall length with a 3/8-inch cutting diameter and a 1.125-inch spiral flute length. It features a straight cylindrical shank and right-hand cut geometry. Machinists and tool-and-die professionals use this drill in general-purpose metal removal applications where precise hole location is required before finish drilling or reaming.

This spotting drill is suited for use in manual mills, CNC machining centers, and drill presses working with ferrous and non-ferrous metals in job shop, maintenance, and production environments. The 90-degree included point angle is compatible with standard drill point geometry, allowing clean seat transfer to the follow-up drill. The Series SPRG-90 design is a single-ended tool sold individually per package.

Key Features

• 90-degree drill point angle for accurate spotting and chamfering on standard drilled holes
• TiN coating reduces cutting friction and extends tool life compared to uncoated HSS
• High speed steel construction handles general-purpose metal cutting at conventional spindle speeds
• Two-flute spiral geometry promotes chip evacuation during spotting operations
• Straight cylindrical shank fits standard drill chucks and collet holders accepting 3/8-inch shank tooling
• Single-ended design with 1.125-inch flute length suited for shallow spotting passes

Compatibility

Designed as a general-purpose spotting drill for use in standard drill chucks and collet systems accepting a 3/8-inch straight cylindrical shank, compatible with manual and CNC machine tools running Series SPRG-90 tooling.

Installation Notes

Installation and use of this tool should be performed by a qualified machinist or toolroom technician. Ensure the machine spindle is fully stopped and the tool holder is clean and free of debris before seating the shank. Verify chuck or collet runout is within acceptable tolerances before operating, as excessive runout will degrade spotting accuracy and reduce tool life. Follow machine manufacturer guidelines for spindle speed and feed rate appropriate to the workpiece material.
