Hougen 10816 Drilling Machine Arbor MT3 Taper Shank

Product Description

The HOUGEN 10816 is a taper-shank drilling machine arbor designed to connect annular cutter tooling to drill presses and magnetic base drilling machines equipped with a Morse Taper 3 spindle. The arbor accepts cutters with a 2.375-inch hole diameter and provides a 1.5-inch arbor body diameter for solid tool engagement. At 6.44 inches overall length, it delivers adequate clearance for most production and maintenance drilling applications. Licensed machinists, millwrights, and industrial maintenance technicians install this arbor as part of a complete annular cutter setup on ferrous and structural steel workpieces.

This arbor is suited for use in fabrication shops, structural steel work, and on-site maintenance environments where MT3-spindle drilling machines are standard equipment. It is intended for use with annular cutters requiring a 2-3/8 inch pilot hole diameter. Typical applications include hole-making in plate steel, beam flanges, and machine frames where annular cutters outperform twist drills in speed and material removal efficiency.

Key Features

• MT3 Morse Taper shank provides positive, self-holding engagement with compatible drill spindles
• Accepts annular cutters with a 2.375-inch cutter hole diameter
• 1.5-inch arbor body diameter for rigid tool support during high-torque cutting
• 6.44-inch overall length offers clearance for standard drilling machine setups
• 0.938-inch shank diameter sized to MT3 taper specification

Compatibility

Designed for use with MT3-spindle drilling machines and annular cutters requiring a 2-3/8 inch cutter hole diameter. Verify spindle taper type before installation to confirm fitment with your specific drilling machine.

Installation Notes

Installation should be performed by a qualified machinist or industrial maintenance technician familiar with Morse Taper tooling. Clean and inspect both the arbor taper and machine spindle bore before seating to ensure full contact and prevent runout. Use a draw bar or drift bar as appropriate for your machine spindle design when seating or removing the arbor. Never use the arbor with a cutter that does not match the specified hole diameter, as improper fitment can cause tool ejection and injury.
