Electric locator Function: A tool holder accessory designed to fix drills, milling cutters, grinding tools and other tools, with a cover to secure them. Benefits: Provides secure clamping, reduces tool movement during operation, and helps quick and repeatable setups. How it works: Tools are clamped in the locator and covered to hold them firmly in place during use. Compatibility: Suitable for drills, milling cutters, grinding tools and other similar accessories. Notes: Specific size and material are not specified. Grinding positioner Function: Allows the grinding accessory to rotate directly in the holder for fixation during electric grinding. Benefits: Enables precise positioning and stable fixation without manual readjustment. How it works: The grinding accessory rotates within the holder and locks in the desired position for consistent grinding. Compatibility: Works with electrical grinding setups and related grinding accessories. Notes: Described as an electric grinding accessory. Drilling locator Function: Enables changing drilling depth by turning the shaft and locks it securely with the side screw. Benefits: Delivers precise, repeatable drilling depth and secure depth locking. How it works: Turn the shaft to set depth, then tighten the side screw to fix the setting. Compatibility: Intended for use with standard drilling operations and compatible tools. Notes: Also referred to as a grinding guide locator in the description. Positioner Function: Improves precision and control on a variety of tasks by providing the needed support and stability. Benefits: Enhances stability, reduces deviation, and serves as a guide tool for grinding tasks. How it works: Provides a steady guide surface and reliable support during operation. Compatibility: Works as a general grinding guide tool in conjunction with the other components. Notes: Functions as a stable platform to improve accuracy. Use scenarios Scenario 1: Drilling with controlled depth in metal or wood. Use the drilling locator to set and lock the exact depth, clamp the drill with the electric locator, and use the positioner to stabilize the workpiece for repeatable results. Scenario 2: Precision grinding or sharpening. Mount the grinding accessory in the grinder holder using the electric locator, adjust the position with the grinding positioner for exact angle, and rely on the positioner to provide a stable guide during repeated passes. Scenario 3: Smallbatch milling or setup tasks. Use the electric locator to fix milling cutters in place, rotate and lock the grinding positioner as needed, and employ the positioner to maintain consistent alignment across operations.
