Keo 956-000-064 Spotting Drill 1/2 in 120 Pt Hss

Product Description

The KEO 956-000-064 is a single-ended spotting drill designed to create accurate center points and guide holes for follow-on drilling operations. Built from high-speed steel with a bright, uncoated finish, it features a 120-degree point angle and a 0.500-inch cutting diameter. The two-flute spiral design and right-hand cutting direction provide clean, consistent entry points across a wide range of workpiece materials. At 3.750 inches overall length with a 1.375-inch flute length, this tool is suited for general-purpose spotting in machine shop, fabrication, and maintenance environments. Machinists, toolmakers, and maintenance technicians are the primary users.

This spotting drill is used in general-purpose drilling setups on drill presses, CNC machining centers, and manual milling machines. It is particularly well suited for establishing precise hole locations before step drilling or deep-hole drilling operations in metal fabrication, production machining, and field maintenance work. The 120-degree point angle is a common choice for pre-spotting holes that will be finished with standard 118-degree or 135-degree twist drills, helping to reduce walking and improve positional accuracy.

Key Features

• 120-degree drill point angle for accurate pre-spotting ahead of standard twist drills
• 0.500-inch cutting diameter with matching 0.500-inch straight cylindrical shank
• High-speed steel construction for general-purpose metalworking applications
• Bright, uncoated finish - ready to run as delivered or compatible with post-purchase coating
• Two-flute spiral geometry with right-hand cut for clean chip clearance
• Single-ended design at 3.750 inches OAL for standard toolholder and chuck setups

Compatibility

Designed as a general-purpose spotting drill compatible with standard drill chucks, ER collet systems, and toolholders accepting a 0.500-inch straight cylindrical shank on drill presses, CNC machining centers, and manual mills.

Installation Notes

Installation is performed by machinists or toolmakers using a standard drill chuck or collet system. Ensure the machine spindle is fully stopped and the tool is seated and secured before beginning any operation. Verify shank engagement depth meets the toolholder manufacturer minimum before applying cutting forces. Follow applicable shop safety procedures and machine-specific operating guidelines when setting speeds and feeds.
