Bores single holes or 2 holes in-line from 1.75 to 5.5 inches diameter spaced to about 20 inches apart.

1.50" dia x 36" long Boring Bar - made from highest quality chrome induction hardened and precision ground 100,000 PSI tensile strength alloy steel. The chrome resists burrs and scoring to still fit the bearings use after use. Cutting Bit mounting holes are spaced 5 inches apart. 3/4" shank with 3 flats for solid gripping by your drill chuck.
1 Drill Base Adapter with built-in bearing - Important safety device to hold the magnetic drill press in case of power failure. The built-in bearing takes the load of the boring shaft to prevent overloading the internal drill press bearings. Includes mounting hole for BOA-408-AMT bore welder.
2 Self-aligning Bearings - the I.D. of the bearings have a perfect fit between bar and bearings, which insures holes can be bored to near zero TIR runout.
2 Bearing Plates and 4 Standoffs - 3/4 inch thick for easy weld on and vibration free machining.
2 Centering Cones - for quick concentric alignment of the boring bar and bearings in larger holes.
2 Centering Sleeves - for quick concentric alignment of the boring bar and bearings in smaller holes.
7 Bore Cutting Tools - 3 types of boring, 1 chamfering and 1 facing. Held in the boring shaft by heavy set screws.
1 Electronic Caliper - Measures 0" to 8" with digital readout to .001" in/mm
1 Telescoping Bore Gage Set - To measure the diameter of your holes.
1 Wood case - with dolly wheels.

Powered by your magnetic drill with 3/4" drill chuck.
