      Operating Instructions
      Step 1: Place boring bar suitable for boring range in the mounting hole of boring head. Keep flattened side of boring bar facing same direction with locking screw. Make sure cutting edge is facing the front direction with adjusting panel. Fasten the locking screw properly.
      Step 2: Loosen adjusting screw anti-clockwise.
      Step 3: Enlarge the boring diameter by adjusting anti-clockwise on the adjusting panel, while adjusting clockwise is to reduce the boring range.
      Step 4: Lock the adjusting screw clockwise properly to finish adjustment.

      Frequently Asked Questions
      QWhat is the dial precision of the DBJ10/12/16 micro-boring heads?
      All three DBJ series micro-boring heads (DBJ10, DBJ12, and DBJ16) feature a dial precision of 0.01 mm, allowing for highly accurate and repeatable boring diameter adjustments.
      QWhat is the boring range of the NBH2084 micro-boring head?
      The NBH2084 micro-boring head covers a wide boring range of 8–280 mm, making it suitable for a broad variety of precision boring applications. It has a micro distance of 28 mm and a dial precision of 0.01 mm.
      QHow do I properly adjust the boring diameter on the DBJ series boring head?
      First, loosen the adjusting screw anti-clockwise. Then rotate the adjusting panel anti-clockwise to enlarge the boring diameter, or clockwise to reduce it. Once the desired diameter is reached, lock the adjusting screw clockwise to secure the setting. Always ensure the locking screw is loosened before making any adjustments.
      QWhat adapter sizes are compatible with the DBJ tool kits?
      The DBJ tool kits are available with BT40 and BT50 adapters. For example, the BT40-DBJ10-6PCS uses a BT40-DCK4-70 adapter, and the BT50-DBJ12-7PCS uses a BT50-DCK5-90 adapter. The NBH2084 kit is compatible with BT40-NBH-A50 and BT50-NBH-A50 adapters.
      QWhat items are included in a standard DBJ or NBH2084 micro-boring tool kit?
      Each standard kit includes: one boring adapter, one micro boring head, seven (or six, depending on model) micro boring bars, and three wrenches. All components are designed to work together for complete precision boring operations.
      QWhat should I do if the adjustment becomes very difficult or faces strong resistance?
      Stop adjusting immediately. Check that the locking screw is fully unlocked (loosened) before attempting further adjustment. Also verify that the adjustment is still within the recommended boring range. Forcing the adjustment beyond the specified range may damage the tool.
