The DB-21 is a 21 spindle construction boring machine which drills in both the vertical and horizontal directions producing a perfectly aligned pattern of edge and face construction holes. The DB21 has a pneumatic head tilt to go between vertical and horizontal boring. Also this machine comes with four hold down clamps instead of three as shown in the brochure. Line boring is available on this machine as an option.

Advantages of dowel construction:
Dowels have been part of woodworking and cabinetmaking forever, whether it’s chairs, cabinets or frames.. The reason is dowel construction is extremely strong. Dowels are also inexpensive and there is a lot of machinery available to insert and assemble with dowels.
Advantages of Dowel Construction- Once parts are machined dowel assembly forces the assembler to put the work piece together the correct way. There are no screw heads showing and no misaligned parts. To speed assembly a case clamp can be used. 
The advantages of using a case clamp- while glue is setting up, on a work piece in the clamp, the back can be installed. Squareness is guaranteed. Meanwhile the next cabinet can be pre-assembled and readied for when the preceding cabinet comes out of the clamp.Three to five minutes of clamp time is usually required for initial setup of glue depending on temperatures and the type of glue used.
