Clarke 6500023 CMA1B Attachment Instructions

To attach the Clarke 6500023 CMA1B Mortise Attachment to your drill press, first ensure the power is disconnected. Remove the existing chuck from the drill press spindle. Attach the mortise attachment by aligning its spindle adapter with the drill press spindle, then secure it using the provided set screws.
The Clarke 6500023 CMA1B Mortise Attachment can handle chisels up to 3/4 inch in size. Ensure you use compatible chisels to avoid damaging the attachment or workpiece.
To prevent wood from splintering, use sharp chisels and drill bits, and ensure the workpiece is securely clamped. Applying a piece of tape over the drilling area can also reduce splintering.
Regular maintenance includes cleaning the attachment after each use, ensuring all moving parts are lubricated, and checking for any loose screws or components. Periodically sharpen the chisels for optimal performance.
First, insert the chisel into the attachment and slightly tighten it. Insert the bit through the chisel and into the drill press chuck. Adjust the chisel so that its sides are parallel to the workpiece, then fully tighten the chisel and bit. Ensure there is a small gap between the bit shoulder and chisel to allow wood chips to escape.
If the mortise attachment is not cutting cleanly, check if the chisels and bits are sharp and properly aligned. Ensure there is no debris in the chisel slots. If everything is in order, reduce the feed rate to allow the tool to cut more effectively.
The Clarke 6500023 CMA1B Mortise Attachment is designed for woodworking. Using it on materials such as metal or plastic is not recommended as it may damage the attachment or produce unsatisfactory results.
To adjust the depth of cut, use the depth stop on your drill press. Set it to the desired depth by loosening the stop, adjusting to the correct position, and then retightening. Ensure the depth is checked with a test piece before proceeding with your main workpiece.
Store the mortise attachment in a clean, dry place. Disassemble the chisel and bit from the attachment, clean them thoroughly, and apply a light coat of oil to prevent rust. Keep all components in a secure box or case to protect them from damage.
If the mortise attachment wobbles during operation, check that it is securely attached to the drill press and that all screws and bolts are tight. Inspect the chisel and bit for proper installation and alignment. If wobbling persists, inspect the spindle adapter for wear or damage.
