Spi 13-160-7 Electronic Edge Finder 0.4 Inch Head

Product Description

The SPI 13-160-7 is an electronic edge finder designed for precision workpiece location on milling machines, machining centers, and similar CNC or manual setups. The tool uses a ball contact tip to detect the edge of a workpiece and triggers a visual alert when contact is made, allowing the operator to establish a datum with an accuracy of 0.0004 inches (0.01 mm). The 0.4-inch head diameter and 3/4-inch shank diameter suit standard tool holders and collet chucks found in most shop environments. Machinists and CNC operators rely on this style of finder to reduce setup time and improve repeatability across production runs.

The 13-160-7 is suited for use in job shops, toolrooms, and production machining environments where accurate edge and centerline location is required. Its single-end configuration with ball contact head is a standard approach for locating part edges before beginning a cut. The 3-3/4-inch overall length positions the contact tip well below most spindle noses, keeping it clear of fixturing in typical vise or fixture-plate setups. No magnetic mounting is involved; the shank seats directly in the spindle collet or tool holder.

Key Features

• Electronic operation with visual edge alert for clear, repeatable detection
• Ball contact head type for consistent point contact on part edges
• 0.0004 inch (0.01 mm) accuracy for high-precision datum setting
• 0.4 inch head diameter with 3/4 inch shank fits standard collets and tool holders
• 3-3/4 inch overall length provides clearance in common fixturing setups
• Single-end design for straightforward edge and centerline location

Compatibility

Designed as an OEM-style precision tool for use in milling machines and machining centers equipped with standard collet or end-mill holders accepting a 3/4-inch shank diameter.

Installation Notes

Installation is performed by a machinist or CNC setup technician. Seat the shank securely in a compatible collet or tool holder and torque the drawbar or collet nut per the machine manufacturer's specification before use. Power down or enable the spindle-lock function on the machine before inserting or removing the tool. Do not operate this finder at high spindle speeds; consult the machine tool documentation for the maximum allowable RPM for edge-finding operations.
