Keo 955-000-087 Spotting Drill 1.75in 90pt Hss

Product Description

The KEO 955-000-087 is a single-ended spotting drill designed to create accurate starter holes and precise drill point locations in metal workpieces. Manufactured from high-speed steel with a bright, uncoated finish, it features a 90-degree point angle and a 1.75-inch cutting diameter. The straight-cylindrical shank measures 1.75 inches in diameter, making it suitable for use in large-capacity drill chucks and milling machine spindles. With a 5.5-inch overall length and 2.75-inch spiral flute length, this tool is built for general-purpose spotting applications in machine shop and production environments. It cuts right-hand and runs in two flutes for chip clearance.

This spotting drill is intended for use in machine shop environments where accurate hole location and consistent countersink geometry are required before full-depth drilling. It is appropriate for use on machining centers, knee mills, drill presses, and manual lathes equipped with appropriate toolholding. The large 1.75-inch diameter makes it well-suited for spotting oversized hole patterns or pre-locating large-diameter twist drills. Machinists, tool and die makers, and production machine operators are the primary users. No specific compatible machine models are provided by the manufacturer for this part.

Key Features

• 90-degree point angle for standard spotting and countersink prep

Compatibility

Designed as a general-purpose spotting drill for use in machine tools equipped with toolholding capable of accepting a 1.75-inch straight-cylindrical shank.

Installation Notes

Installation and operation should be performed by a qualified machinist or toolroom professional. Ensure the machine spindle and toolholder are fully powered down and locked out before mounting or removing the drill. Verify that the toolholder bore matches the 1.75-inch shank diameter to prevent runout and tool pullout during cutting. Follow applicable shop safety protocols and machine manufacturer guidelines for speeds and feeds when running high-speed steel tooling.
