Key benefits Reduced risk of blade-head breakage by keeping the knife rod perpendicular to the workpiece during cutting. Simple, reliable operation with electric drills when the correct start/stop sequence is followed. Fast, straightforward blade and tool-seat replacement using the anti-loosening nut, set screw, and compression cap. Longer blade life and cleaner cuts when the blade is lubricated regularly, especially on aluminum plates. What it does and how it works Function: precision cutting using a blade mounted in a knife-rod assembly for use with an electric drill. Compatibility: intended for use with an electric drill as described; blade and tool-seat assembly use an anti-loosening nut, set screw, and compression cap for secure mounting. Maintenance and performance: routine lubrication reduces friction and heat buildup, improving cut quality and extending blade life—important when working with aluminum plates. Usage and operation steps Cutting orientation: always keep the knife rod perpendicular to the workpiece to avoid undue stress and prevent the knife head from breaking. Drill sequence: switch the electric drill on first, perform the cut(s), and finish the cutting process before switching the drill off. Blade replacement: 1. Open the cover. 2. Remove the anti-loosening nut and loosen the set screw. 3. Pull the blade out, replace it, then retighten the set screw and anti-loosening nut. Tool-seat replacement: 1. Unscrew the compression cap counterclockwise. 2. Replace the tool seat with the new one and reassemble. Lubrication: oil the blade frequently—this is especially important when cutting aluminium plates to avoid gumming, overheating, or premature wear. Practical applications Trimming and shaping aluminum plates and panels where clean edges and long blade life are required. Small metal-repair tasks and sheet-metal trimming using an electric drill-mounted blade assembly. Workshop and DIY cutting tasks on a variety of workpieces where controlled, perpendicular cutting improves safety and results. Safety and care reminders Maintain perpendicular blade alignment at all times while cutting. Do not turn off the drill mid-cut; complete the cut before powering down. Follow the blade and tool-seat replacement steps precisely to ensure secure mounting. Keep blades oiled and inspect mounting hardware (anti-loosening nut, set screw, compression cap) regularly for tightness and wear.
