There is no more accurate way of drilling holes than through a drill bushing. The DJ-3 Universal Drilling Jig allows for two drill bushings to be inserted with a maximum drill size of 1/2” (13 mm). Compared to the previous generations of Bridge City Drill Jigs, DJ-3 features a new and improved stop system, and an adjustable jaw for off-center drillings. 

Using a similar dual cable adjustment system as the Bridge City CS-3 CenterScribe, the DJ-3Universal Drilling Jig will self-center on stock up to 12-13/32” (315 mm) in width. In addition, the DJ-3 will allow for off-center drilling up to 30 mm from center. Also, the DJ-3 Jaws are configured to hold cylindrical stock and spheres. With different configurations, DJ-3 is able to handle 9different drill applications as below:

As you will soon learn, the DJ-3 can easily be thought of as a drill press in a box. It offers a legitimate answer to the drilling needs of many customers without sufficient space.

The bushings are made of tool steel, hardened to a rockwell of 60-62 HRC. After thousands of hours of research and experiments, we found that this specifichardness gave the maximum life to both the bushings and the drill bits, so that the drilling accuracy is guaranteed.

In addition, the bushings have a tolerance of 10 microns, which ensures every hole drilled using this jig will be incredibly accurate.

The DJ-3 Universal Drilling Jig is mostly made of 6061 aircraft grade aluminum alloy for excellent rust resistance.

In addition, the DJ-3 Drilling Jig is anodized for a vibrant and decorative finish with strong corrosion and wear resistance.

The DJ-3 Universal Drilling Jig comes with the Standard Bushing Kit including 28 bushings of the following sizes:

Eleven Imperial Bushings:1/16" x1, 1/8" x1, 3/16" x1, 1/4" x2, 5/16" x1, 3/8" x2, 7/16" x1, 1/2" x2.

Seventeen Metric Bushings:1mm x1, 2mm x1, 3mm x1, 4mm x2, 5mm x1, 6mm x2, 7mm x1, 8mm x2, 9mm x1, 10mm x2, 11mm x1, 12mm x1, 13mm x1.

Using a similar dual cable adjustment system as the CS-3 CenterScribe, the DJ-3 Universal Drilling Jig can automatically align the bushings with the centerline of the workpiece. The maximum width of stock that can be drilled in this case is up to 12-13/32” (315mm).

The DJ-3 will also allow for off-center drilling up to 30 mm from center by using the laser-etched graduation on the back of the adjustable jaw. 

Milled into the removable jaws of the DJ-3 are two “V” grooves for drillingperpendicular holes on round or tube stock. 

The maximum diameter of stock that can be drilled in this case is up to 2-3/8” (60mm).

Round stock of ANY length can be drilled axially with the DJ-3 Universal Drilling Jig. This is the use that a drill press cannot compete with.The maximum diameter of stock that can be drilled in this case is up to 12-13/32” (315mm).

Because of the bushing we are using, the larger drills bits will not drift off the center line. The maximum side length of stock that can be drilled in this case is up to 1-19/32” (40.5mm).

Square stock of ANY length can be drilled axially with the DJ-3 Universal Drilling Jig. This is the use that a drill press cannot compete with.

The maximum side length of stock that can be drilled in this case is up to 8-55/64” (225mm)

Spheres from 5/16” (8mm) to 2-3/8” (60mm) in diameter can also be easily drilled with the DJ-3 Universal Drilling Jig.

Want miter joints that can be strengthened with dowels?

The DJ-3 Universal Drilling Jig, when fitted with the 45° miter jaws, will always drill holes perpendicular to the mitered edge directly on the centerline.

Stock of ANY length can be drilled with the 45° miter jaws, and the maximum width of stock that can be drilled in this case is up to 7-9/32” (185mm).

*This drilling application must be completed in conjunction with the optional Jaw Kit DJ-3-J.

In conjunction with Long Accessory Jaws, the large diameter bits with nominal shank diameters can be used for drilling large holes. 

Using this setup, holes can be drilled up to 45 degrees. The maximum thickness of stock is up to 5-5/16” (135mm).
